An account entitles designated cloud users the right to use computing, network, and storage resources of vDC. The account provides the required capabilities to manage these resources. Account defines the amount of vCPU, memory and storage resources that can be used from the available vDC resources.
The Actions pane is used to start jobs based on the current selection in the Navigation pane. Selections in the Navigation pane or center pane change the display of operations in the Actions pane. The Actions pane is subdivided into four sections – Operate, Organize, Deploy, and Update.
Reflects the state of system and indicates whether monitoring is actually being performed. The active state is not editable. When a rule is not enabled, monitoring is not active. The status is displayed on the Alert Monitoring Rules page, which is accessed from the Monitoring tab. Text in the Active field indicates whether the parameter is active.
Changes an inactive Oracle Solaris boot environment to the new default boot environment on reboot.
The Agent Controller software communicates with the Enterprise Controller and is installed automatically when an asset is discovered to make the asset a managed asset. You can choose to manage resources remotely with proxy resources without putting an agent on the system. Some features of the product don't work without the agent, but discovery manages the assets without putting an agent on them.
A system that is managed with Oracle Enterprise Manager Ops Center without the Agent Controller software being installed.
Monitors the state of managed resources and their attributes and raise an alert when the state is outside the pre-defined thresholds.
An alternate boot environment, or ABE, is an inactive Oracle Solaris boot environment.
Annotations are scripts or comments that you can associate with a incident. Annotations can be automated operations to solve a incident, a suggested action, or a comment. You can associate an annotation with a specific incident. Annotations can be added to the Incidents Knowledge Base.
Assemblies are kind of infrastructure templates that contain a configuration of multiple virtual machines with their virtual disks and the inter connectivity between them. Assemblies can be created as a set of .ovf (Open Virtualization Format) and .img (disk image) files, or may all be contained in a single .ova (Open Virtualization Format Archive) file.
Assets are physical or virtual piece of hardware, storage device, or operating system that you can manage with Oracle Enterprise Manager Ops Center.
An auto-balancing policy determines if, and how, a server pool is automatically load balanced. By default, automatic balancing is not selected. When you designate the server pool for automatic balancing, the software reviews the load on the virtualization hosts for the interval and day that you request. The software then migrates the guests, as needed, to balance the load. You can require administrator approval before the guests are moved. Also see placement policy and policy.
Bandwidth flow is the speed of a connection, or the amount of data that flows from a site's server out to the viewer at any given time.
A dated collection of Oracle Solaris patches, patch metadata, and tools. Oracle releases Solaris baselines on a monthly basis. You can use the black lists and the white lists to modify a baseline and create a custom patch set.
Baseline check is a feature of Oracle Enterprise Manager Ops Center Engineered Systems where the factory setup of eighth, quarter, half, and full rack configurations are considered as a normal or ideal setup. When the assets are discovered and associated with the rack, this setup is compared with the normal factory setup.
A list of Oracle Solaris operating system patch IDs that you never want to apply to an asset. The black list is used when you are using a baseline to update an Oracle Solaris operating system.
A block storage library consists of LUNs (Logical Unit Number). Each LUN is a slice of a storage volume, which is storage space provided by a collection of disks.
A collection of mandatory file systems (disk slices and mount points) that are critical to the operation of the Oracle Solaris operating system. These disk slices can be on the same disk or distributed across multiple disks.
Zones that are capable of emulating user environments from operating systems other than Oracle Solaris 10. Zones supports different versions of Oracle Solaris operating system in the zones for running applications.
For Oracle Enterprise Manager Ops Center's Local Content, a category is the type of software that is uploaded to Oracle Enterprise Manager Ops Center for use at a site. The parent category is one of the types defined in Oracle Enterprise Manager Ops Center. The local category is a category defined for the site, for example a script for a quarterly inventory.
An operating system distribution, such as Oracle Solaris 10 5/09 on x86 platform or Oracle Linux 5.5. A channel is also called a distribution.
A cloud is a set of physical resources that can be divided and allocated to multiple users who can in turn create and use virtual resources as needed without impact to or awareness of the other users' resources. A cloud is implemented as a pool of servers sharing the same virtualization type, storage, networks and fabrics.
Cluster heartbeat is used to verify if the Oracle VM Servers in a clustered server pool are up and running. The heartbeat function has a network component, where a TCP/IP communication channel is created with each Oracle VM Server. Each Oracle VM Server sends regular keep-active packets and these packets are used to determine if each Oracle VM Server is active.
This is the default connection mode for Oracle Enterprise Manager Ops Center. With this mode, patch data is regularly downloaded from Knowledge Base through an Internet connection.
A domain that is created when Oracle VM Server for SPARC software is installed. The control domain contains the software packages for Oracle VM Server, including the domains manager application and the domains manager daemon (ldmd) process required for managing the logical domains. The interface to the hypervisor is through the domains manager. The control domain enables you to create, and manage logical domains and allocate virtual resources to the domains.
File systems that are required by the Oracle Solaris operating system. When you use Solaris Live Upgrade, these file systems are separate mount points in the vfstab file of the active and inactive boot environments. Example file systems are
/opt. These file systems are copied from the source to the inactive boot environment.
Displays a high-level overview of an asset or a group of assets on the user interface. The information of the selected asset or group is displayed in the Center Pane.
Defines the sequence of steps that must be carried out on an asset to deploy. Deployment plans also include the specification or profile that each step should apply, and the resources that are required to apply it such as network addresses, host names and so on. Customized deployment plan enables you to perform hardware, firmware and operating system provisioning activities in a repeatable fashion.
This is the alternate connection mode for Oracle Enterprise Manager Ops Center. Instead of relying on an Internet connection for updates, patch data is acquired using the harvester script and moved to the Enterprise Controller.
This is the method for adding assets to Oracle Enterprise Manager Ops Center. Assets can be discovered using a variety of protocols, by their service tags, or by declaring hardware so that it can be configured and provisioned with an operating system.
For an operating system, a distribution is a specialized version of the operating system.
Distribution groups are defined especially for Oracle Exalogic system based vDCs. Place your vServers in a distribution group and ensure that no two vServers run on the same Oracle VM Servers.
DNS is a network protocol that issues IP addresses within a specified range to devices on the network.
In M-Series servers, you can partition the available hardware resources into smaller logical systems called as dynamic system domains. Dynamic System Domains run their own copies of the operating system and offer a very high level of isolation from other domains in the system because the partitioning occurs at the hardware level.
When the block storage library uses LUNs constructed from a storage array that is a managed asset, the block storage library is dynamic. You can add storage capacity as needed by adding LUNs supplied by the storage array.
When the block storage library relies on a storage array that is not a managed asset, the block storage library is static. Because Oracle Enterprise Manager Ops Center has less information about the storage array, you cannot increase the number of LUNs in the storage library.
A monitoring rule that is enabled is actively monitoring a parameter. By default, all rules are enabled. Users can disable and enable parameters on a per asset or group basis. The status is displayed on the Alert Monitoring Rules page, which is accessed from the Monitoring tab. Text in the Enabled field indicates whether the parameter is enabled.
This is the central server for Oracle Enterprise Manager Ops Center software. The Enterprise Controller hosts the user interface and communicates with the Knowledge Base. Enterprise Controller stores management information, such as firmware and operating system images, plans, profiles, and policies and also stores the asset data and site customizations. All operations, or jobs, are initiated from the Enterprise Controller.
A dedicated network interface is allocated to the zone. You can choose the network interface when you assign the network to a zone.
A monitoring rule that uses an instruction to execute something that returns a value.
The directory that contains critical system configuration files and maintenance commands.
The directory on a WANboot server that contains the client configuration information and security data that are required for a WANboot installation.
A file system on an operating system server that is shared with other systems on a network. For example, the /export file system can contain the
root ( / ) file system and swap space for diskless clients and the home directories for users on the network. Diskless clients rely on the /export file system on an operating system server to boot and run.
Fabrics are network topologies where network nodes connect with each other through one or more network switches. A true fabric provides a direct connection between any two ports, and supports single step/lookup-based processing. Regardless of its various components, a fabric appears on the outside as a single, logical device with a single, consistent state.
The term is popular in telecommunication, Fibre Channel storage area networks, and other high-speed networks, including InfiniBand.
A software or storage library that relies on a file system on the Enterprise Controller's system or a shared file system on an NFS server that the Enterprise Controller mounts.
In Oracle Solaris Zones, the global zone is both the default zone for the system and the zone used for system-wide administrative control. The global zone is the only zone from which a non-global zone can be configured, installed, managed, or uninstalled. Administration of the system infrastructure, such as physical devices, routing, or dynamic reconfiguration (DR), is only possible in the global zone. Appropriately privileged processes running in the global zone can access objects associated with other zones.
A group is a user-defined set of assets. Assets can be added to groups based on asset attributes such as type or location. A group can include other groups. Assets can be manually added in addition to the rules based addition using attributes. Any type of asset that can be in a group can be added manually to any user-defined asset group.
Guest refers to a virtual machine that is configured and installed in a virtualization host. For example, the logical domains in an Oracle VM Server host are referred to as guests in a server pool.
Globally Unique Identifier. A pseudo-random 128-bit number that is computed by Windows to identify any component in the computer that requires a unique number. In Oracle Enterprise Manager Ops Center, GUIDs are used to identify LUNs.
Hardware virtualization is a technology that is used to create multiple virtual systems on a single piece of physical hardware. When you create a hardware virtualized (HVM) guest, you must supply an ISO file in a repository to create the virtual machine.
PVHVM is identical to HVM, but has additional paravirtualized drivers for improved performance of the virtual machine. PVHVM improves the performance level of Microsoft Windows running in guests.
The name by which a system is known to other systems on a network. This name must be unique among all the systems within a particular domain (usually, this means within any single organization). A host name can be any combination of letters, numbers, and dashes ( - ), but it cannot begin or end with a dash.
A hypervisor is the software that enables multiple virtual machines to be multiplexed on a single physical machine. The hypervisor code runs at a higher privilege level than the supervisor code of its guest operating systems to manage use of the underlying hardware resources by multiple supervisor kernels.
Image Packaging System is an Oracle Solaris 11 package that contains operating system components and a manifest that provides basic metadata.
An event that triggers an alert when a monitored attribute does not meet the monitoring parameters. A new incident is displayed in the Unassigned Incidents queue in the Message Center. From the Message Center you can view and act on incidents.
InfiniBand is a switched fabric communications link primarily used in high-performance computing. Its features include quality of service and failover, and it is designed to be scalable. The InfiniBand architecture specification defines a connection between processor nodes and high performance I/O nodes such as storage devices.
InfiniBand transmission rates begin at 2.5 GBps.
IPMP (IP network multipathing) provides physical interface failure detection and transparent network access failover. You can configure one or more physical interfaces into an IP multipathing group, or IPMP group. After configuring IPMP, the system automatically monitors the interfaces in the IPMP group for failure.
JumpStart Enterprise Toolkit provides a framework to simplify and extend the JumpStart functionality provided within the Oracle Solaris operating system. You can use JET to install Oracle Solaris on the SPARC and x86/64 platforms. You create JET templates to customize the operating system configuration options as required.
Java Management Extensions (JMX) technology provides the tools for building distributed, modular, and dynamic solutions for managing and monitoring devices, applications, and networks. The JMX API defines the notion of MBeans, or manageable objects, which expose attributes and operations in a way that enables remote management applications to access them. The public API in Oracle Enterprise Manager Ops Center can be accessed through JMX-Remoting.
The Knowledge Base is the repository for metadata about Oracle Solaris and Linux operating system components. Knowledge base stores information about patch dependencies, patch compatibilities, withdrawn patches, downloads, and deployment rules and also stores URL of operating system vendor download sites and downloads the components at set intervals. The Enterprise Controller must have Internet connection to connect to the Knowledge Base.
Least allocated is a parameter in the server pool placement policy. The lowest allocated CPU and memory is the total static resource allocation across all guests on the virtualization host. The other placement policy parameter is relative load.
A collection of virtual machine images and disk images that are located under the same file system. When a server pool is created, one or more libraries are assigned to the server pool. Server pools can share the same libraries.
Link aggregation is a standard defined in IEEE802.3ad. An aggregated link consists of several interfaces on a system configured as a single, logical unit. Link aggregation increases the speed and high availability of a connection between a server and a switch.
LUN stands for Logical Unit Number. In storage, a LUN is the number assigned to a SCSI protocol entity, that handles (I/O) operations. A SCSI target provides a LUN for each storage volume.
An asset is managed when Oracle Enterprise Manager Ops Center can monitor it and target it with jobs. Operating systems can be managed with or without an Agent Controller, but operating system update functions are only available with an Agent Controller.
Each Oracle Solaris 11 package has an associated manifest that describes how the package is put together. The package manifest provides basic metadata about the package (such as name, description, version, and category), what files and directories are included, and the package dependencies.
Shows a graphical relationship between assets and status of the connection. A blue line shows the working connection and a red line represents the faulted or disconnected status. The membership graph is displayed in the Center Pane.

MTU stands for Maximum Transmission Unit. MTU is the largest packet size, in bytes, that can be sent over a network.
A set of monitoring rules that defines alert conditions. Policies are either system-defined, user-defined, or generic. Each monitoring policy contains one or more alert monitors for a specific type of resource. An alert is raised when the state is outside the pre-defined condition.
Contains monitoring parameters that state the values and boundaries for an asset's activity. The set of rules is called a monitoring policy.
MPxIO provides a multipathing solution for storage devices accessible through multiple physical paths. MPxIO is included as a part of the distribution in Solaris 10 onwards.
NAT stands for Network Address Translation. NAT is a protocol that enables a network to use many internal-only IP addresses and a few Internet-facing IP addresses.
Navigation pane is an important part of the user interface of Oracle Enterprise Manager Ops Center. navigation pane contains Message Center, Assets, Plan Management, Networks, Libraries, Reports, vDC Management, and Administration. The Assets section of the Navigation pane lists all the asset that are managed by Oracle Enterprise Manager Ops Center, grouped by its type and the required criteria.
A network enables guests to communicate with each other or with the external world (that is, the Internet). When a server pool is created, one or more networks is assigned to the server pool. Server pools can share the same networks.
Network bonding refers to the combination of network interfaces on one host for redundancy and/or increased throughput. Redundancy is the key factor you use to protect your virtualized environment from loss of service due to failure of a single physical link. This network bonding equals as the Linux network bonding. Using network bonding in Oracle VM might require some switch configuration.
A system of centralized network administration, in which the permissions that grant access to resources in the network are maintained in one or more servers. Network Domains use a hierarchical structure that enables you to assign permissions to collaborate with different departments in an organization.
A large network may have several domains based on the needs of each set of users.
NIS stands for Network Information System. NIS is a network naming and administration system for smaller networks. NIS is similar to the Internet's domain name system (DNS) but designed for a smaller network.
A virtualized operating system environment created within a single instance of the Oracle Solaris operating system. One or more applications can run in a non-global zone without interacting with the rest of the system. Non-global zones are also called zones.
A clone of the type "non-sparse copy" is a disk image file of a physical disk, taking up the space equivalent to the full specified disk size, including empty blocks.
An email, pager, or user interface message that is automatically sent by Oracle Enterprise Manager Ops Center when specified conditions are met. You can configure separate notification profiles for different assets and different users. You can configure the software to send notification for specific incidents, or when a critical or warning incident is detected.
An opaque data is a data type that is incompletely defined in an interface, so that its values can only be manipulated by calling subroutines that have access to the missing information.
Oracle Enterprise Manager Cloud Control is a single, integrated solution for managing all aspects of the Oracle Cloud and the applications running on it. Oracle Enterprise Manager Cloud Control couples a potent, top-down monitoring approach to delivering the highest quality of service for applications with a cost-effective automated configuration management, provisioning, and administration solution.

Oracle Solaris Clusters is a high availability software product for Solaris operating system. Oracle Solaris Clusters are used to improve the availability of software services such as databases, file sharing on a network, electronic commerce websites, or other applications. You can now manage Oracle Solaris Clusters as any other asset using Oracle Enterprise Manager Ops Center.
Oracle Solaris Zones is a software partitioning technology used to virtualize operating system services, and provide an isolated and secure environment for running applications. When you create a non-global zone, you produce an application execution environment in which processes are isolated from all other zones. This isolation prevents processes that run in a zone from monitoring or affecting processes that run in any other zones. See also global zone and non-global zone.
Oracle Solaris 11 Software Update Library repository is located on the Enterprise Controller. This contains the Oracle Solaris 11 packages that you need to install, provision, and update your Oracle Solaris 11 operating system.
Oracle VM Server is a virtualization technology that enables the creation of multiple virtual systems by a hypervisor in the firmware layer, interposed between the operating system and the hardware platform. This is designed to abstract the hardware and can expose or hide various system resources, allowing for the creation of resource partitions that can operate as discrete systems, complete with virtual CPU, memory and I/O devices.
Oracle VM Server for SPARC was previously known as Logical Domains, it is a virtualization technology designed to run on CMT based servers.
Oracle VM Server for x86 is a managed virtualization environment or part of such an environment, that is designed to provide a lightweight, secure, server-based platform for running virtual machines. Oracle VM Server for x86 is based upon an updated version of the underlying Xen hypervisor technology, and includes Oracle VM Agent.
An Oracle Solaris operating system file system that uses storage pools to manage physical storage.
Paravirtualization enables you to select a location for the mounted ISO file from which you create the virtual machine. Before you create the virtual machine using the paravirtualized method, you must mount the ISO file on an NFS share, or HTTP or FTP server.

Photorealistic view displays the front and rear views of the rack. All slots and the respective assets are displayed. Positions within the rack are displayed in a 2-dimensional view. All assets in the rack have a specific image. The health status of assets such as OK, Warning, and Critical are displayed in the form of colored buttons.
Determines whether the guest is placed on a virtualization host with the lowest relative load or the least allocated. By default, new guests are placed on the server with the lowest load and are automatically started. The placement policy is defined when a server pool is created. Server pools can have different placement policies.
Defines how a job is performed and sets the automation level of the job. A policy file is similar to a response file. If there is a conflict between a profile and policy, the profile overrides the policy.
Defines the configuration of components for a specific type of system. By using a profile, you can define what is enabled, and not enabled, to be installed on a system. If there is a conflict between a profile and policy, the profile overrides the policy.
Proxy Controllers link the managed assets to the Enterprise Controller and act as proxies for operations that must be located close to the managed assets, such as operating system provisioning. Proxy Controllers distribute the network load and provide for fan-out capabilities to minimize network load. Proxy Controllers perform management operations on assets and report the results to the Enterprise Controller. An Oracle Enterprise Manager Ops Center installation must have at least one functioning Proxy Controller.
Relative load is a parameter in the server pool placement policy. Lowest relative load is based on the lowest memory and CPU utilization for the virtualization host over the past three weeks. The other placement policy parameter is least allocated.
A repository is a central place that stores an aggregation of data in an organized way, usually in a computer storage. Depending on how the term is used, a repository may be directly accessible to users or may be a place from which specific databases, files, or documents are obtained for further relocation or distribution in a network.
The top level of a hierarchy of items.
root is the one item from which all other items are descended. See
root directory or
root ( / ) file system.
The top-level file system from which all other file systems stem. The
root ( / ) file system is the base on which all other file systems are mounted, and is never unmounted. The
root ( / ) file system contains the directories and files critical for system operation, such as the kernel, device drivers, and the programs that are used to boot a system.
Define the monitoring parameters. The following types of rule parameters are available: Threshold, Boolean Control, Enumerated Control, and Expression. Some parameters are editable. All active parameters can be disabled.

A command file that is associated with one of Oracle Enterprise Manager Ops Center's actions, either before the action occurs (pre-action script), or after the action completes (post-action script).
The organization of users and other domain objects into groups for easy administration of access permissions is known as a security group. A Security Group enables you to specify certain security settings on an instance specific basis. You have the ability to filter traffic based on IP's (a specific address or a subnet), packet types (TCP, UDP or ICMP), and ports (or a range of ports). You can also grant access to an entire security group. This enables your trusted computers to access each other without having to open ports to the public.
Server management is used to manage the physical Oracle VM Servers in a server pool, for example, to update the Oracle VM Agent on the different Oracle VM Servers.
A server pool is a resource pool of virtualization hosts that share compatible chip architecture, which facilitates actions such as moving guests between virtualization host instances. Members of the server pool have access to the same network and storage library resources. Guests can access the images contained in the server pool's library. Several server pools can share the same network and library storage resources.
Server templates provide pre-built images for creating vServers. They can be uploaded individually or as part of an Assembly. Server templates can be created from an existing vServer.
Service tags are XML files that identify assets uniquely. Assets with service tags can be discovered using the Find Assets wizard.
The global zone shares its network interface with one or more zone. You must define the network interface when you assign the network to the global zone.
Snapshot, a point in time image of a volume is a non-bootable copy of a boot environment that uses much less disk space than a boot environment. You can create a boot environment from a snapshot.
A software library can be a local file system on the Enterprise Controller or a mount point on an NFS server. The software library is used to store the operating system images for provisioning, branded images, flars, firmwares, profiles, operating system updates, custom programs and scripts.
A clone of the type "sparse copy" is a disk image file of a physical disk, taking up only the amount of space actually in use; not the full specified disk size.
Specifies the route taken by the network for external access. You define a default gateway for the network; however, this default gateway may not be reachable to a given subnet. In this case, you must add a static route for this specific subnet.
The Status pane in the Jobs section describes about the state of the incidents like jobs in progress, jobs failed, jobs partially successful, jobs stopped, jobs schedules, jobs successful and so on.
Microsoft System Center Configuration Manager (SCCM), is used to update Windows operating systems.
Syncing is the process of reconfiguring or updating the Oracle Solaris 11 Software Update Library with the Oracle Solaris 11 Image Packaging System (IPS).

Attribute specific monitoring rules that are hard-coded into drivers. You can disable a system-defined rule, but cannot edit, move, or reconfigure these types of rules.
A thin clone is a clone of a physical disk that takes up only the amount of disk space actually in use; not the full specified disk size.
Unmanaged storage is the storage resource that is unknown to Oracle Enterprise Manager Ops Center. When you add storage to zones using the native CLI or manage existing zone environments, the zone's storage is not identified and termed as unmanaged.
A network domain provides custom network resources from an Ethernet or InfiniBand fabric to virtualization hosts, server pools, or virtual datacenters so that new networks can be created as needed. A user-defined network domain supplements the Default Network Domain that is always available and cannot be deleted.
Monitoring rules that are associated with, and determined by, the type of managed resource. You can apply a user-defined rule to many different attributes.
A file system on a standalone system or server that contains many of the standard UNIX programs.

/usr file system with a server rather than maintaining a local copy minimizes the overall disk space that is required to install and run the Solaris software on a system.
A file system or directory (on standalone systems) that contains system files that are likely to change or grow over the life of the system. These files include system logs, vi files, mail files, and UUCP files.
vDC is a collection of physical servers and storage that are placed on a common network. These physical resources are organized into a pool that are accessed by self-service users. This offers an access point through which you can allocate and control the resources inside. This is created during the set up phase. An example of a vDC is a single Exalogic system that might consist of multiple racks.
vNets are managed networks and their associated logical (L2) fabrics that can be associated with a vDC and it's Accounts.
vServer is an entity that provides the outward interface of a standalone operating system. This may be a Virtual Machine (VM) or a Solaris Container or a similar construct. This consumes CPU and memory resources. This can be a member of one or multiple vNets.
vServer type is a profile for vServer creation that defines size of memory, size of disk and number of vCPUs to be used when creating a new vServer instance, that is used in combination with a Server Template.
A list of Oracle Solaris operating system patch IDs that you always want to be applied to a host. The white list is used when you are using a baseline to update an Oracle Solaris operating system.
A virtual disk image is a representation of a virtual storage device that is associated with a virtual machine. Such storage can represent a virtual hard disk or a virtual CD/DVD.
Oracle VM Server that are managed by Oracle Enterprise Manager Ops Center is referred to as virtualization host. The virtualization host contains a hypervisor and its local resources and network connections.
A virtual machine is a software implementation of a computing environment in which an operating system or program is installed and run.
A virtual machine typically emulates a physical computing environment, requests for CPU, memory, hard disk, network, and other hardware resources that are managed by a virtualization layer which translates these requests to the underlying physical hardware.
A Virtual Machine Template provides a standardized group of hardware, and software settings that is used repeatedly to create virtual machines configured with those settings.
A virtual server image is the persisted specification and state of a virtual machine. A virtual server is created when you create a guest. The virtual server image contains the general specification of the guest such as CPU, network, memory, and the type of physical storage that is backing the guest. A virtual server image is also referred to as a guest image.
VLAN is a group of network resources connected to different network segments that behave as if they were connected to a single network segment. All transmissions from the VLAN are identified by a unique VLAN tag.
A volume is an identifiable unit of data storage that is sometimes physically removable from the computer or storage system. In tape storage systems, a volume may be a tape cartridge. In mainframe storage systems, a volume may be a removable hard disk. Each volume has a system-unique name or number that enables it to be specified by a user.
WINS stands for Windows Internet Naming Service. The WINS server converts NetBIOS names to IP addresses.
Web Services for Management (WS-MAN) is a specification for managing servers, devices, and applications using web services standards. WS - Man provides a common way for systems to access and exchange management information across the entire IT infrastructure.
