Glossary |
A Storage Automated Diagnostic Environment program that runs on a management host, monitoring its storage elements and diagnosing any problems.
A warning of an existing or approaching alert. See also event.
A subtype of an event that requires user intervention. The term actionable event often describes an alert. See also event.
A disk subsystem, made up of multiple disk drives, that functions as a single large device. A high-availability (HA) array configuration has multiple controller and expansion trays of disk drives.
A disk that serves as a hot spare within an array; a reserve disk that can be made available to all virtual disks within an array. See also hot spare.
The amount of data sent or received by the host per I/O operation; the size of a data unit.
The amount of storage you must allocate to storage elements, including volumes, pools, and virtual disks. Capacity planning should include allocations for volume snapshots and volume copies.
Command-line interface. The SSCS command-line interface is available from the remote CLI client or through an SSCS directory on the Solaris Operating System management software station.
A tray with an installed redundant RAID controller pair. In a Sun StorEdge 6130 array, 1x1, 1x2, 1x3, and 1x8 array types are available.
The route used for communication of system management information, usually an out-of-band connection.
See site LAN.
See direct access storage (DAS).
Any host that uses the system for storage. A data host can be connected directly to the system (DAS) or can be connected to an external switch that supports multiple data hosts (SAN). See also host.
The route taken by a data packet between a data host and the storage device.
A storage architecture in which one or two hosts that access data are connected physically to a storage array.
A physical drive component that stores data.
A notification of something that happened on a device. There are many types of events, and each type describes a separate occurrence. See also alarm and alert.
A tray that does not have a RAID controller, used to expand the capacity of an array. This type of tray must be attached to a controller tray to function.
The process of changing the data path automatically to an alternate path.
The percentage of faults detected against all possible faults or against all faults of a given type.
See Fibre Channel (FC).
A 2-gigabit, bi-directional serial data-transfer protocol, deployed across a wide range of storage hardware and commonly used for storage area network (SAN) configurations.
A networking device that can send packets directly to a port associated with a given network address in a Fibre Channel SAN. The Fibre Channel switches are used to expand the number of servers that can connect to a particular storage port. Each switch is managed by its own management software.
An assembly component that is designed to be replaced on site, without the system having to be returned to the manufacturer for repair. Servicing FRUs is documented in the Service Advisor software.
See field-replaceable unit (FRU).
As a function of the Sun StorEdge 6130 array configuration, a host represents a data host and is mapped to initiators and volumes to create a storage domain. See also data host, initiator.
A controller board on the server that allows the server to attach to external storage. See also initiator.
A group of hosts with common storage characteristics that can be mapped to volumes. See also host.
The drive used by a controller to replace a failed disk. See also array hot spare.
System management traffic that uses the data path between a host and a storage device. See also out-of-band traffic.
On a Fibre Channel network, a host that requests transactions with storage elements. Each connection represents a separate initiator, so if a host is connected to the system through two HBAs, the system identifies two different initiators. Initiators can be grouped into host groups. Sun's MPxIO software provides a round-robin mode, where multiple HBAs are grouped together and the system identifies the group of HBAs as one initiator.
A measure of transaction speed, representing the number of input and output transactions per second.
The identifier for a volume as it is recognized by a particular host. The same volume can be represented by a different LUN to a different host.
See logical unit (LUN).
See media access control (MAC) address.
A Solaris host serving the configuration, management, and monitoring software for the Sun StorEdge 6130 array. The software on the station can be accessed with a browser to run the BI or with a remote thin-scripting client to access the SSCS CLI commands.
media access control (MAC) address
The physical address identifying an Ethernet controller board. The MAC address, also called an Ethernet address, is set at the factory and must be mapped to the IP address of the device.
A design for redundancy that provides at least two physical paths to a target.
System management traffic outside of the primary data path that uses an Ethernet network. See also in-band traffic.
See power distribution unit (PDU).
See storage pool.
The assembly that provides power management for the system. The redundant design uses two PDUs in each system so that the system's data path continues to function if one of the PDUs fails.
See storage profile.
Redundant array of independent disks. A configuration in which several drives are combined into a single virtual drive to improve performance and reliability. Also called a RAID set or a RAID group.
Reliability, availability, and serviceability.
Also called the thin-scripting client, the remote CLI client runs the SSCS command-line interface on any qualified host in the network. The client communicates with the management software through a secure out-of-band interface, HTTPS.
The client must be installed on a host that has network access to the system. The available clients are for the Solaris, Microsoft Windows 2000 and Windows 2003, Linux, HP-UX, IBM AIX, SGI, and Novell operating environments.
Monitoring of the functions and performance of a hardware system from a location other than where the hardware resides.
The remote management host uses Sun Remote Services Net Connect 3.1 software to communicate problems with Sun service.
See storage area network (SAN).
The local area network at your site. When the system is connected to your LAN, the system can be managed through a browser from any host on the LAN.
A copy of a volume's data at a specific point in time.
Sun Storage Command System, the CLI that can be used to manage the array.
An architecture in which the storage host are connected to each other to increase data availability and storage utilization.
Storage Automated Diagnostic Enviroment (StorADE)
An automated fault management system (FMS) for SAN devices. The FMS provides health and telemetry for Sun SAN devices.
A storage partition created through the mapping of initiators to hosts and the mapping of volumes to hosts or host groups.
A collection of volumes with a common configuration, availability, and performance. You assign a profile to a pool to define the attributes of the pool.
A set of storage pool attributes that optimize the storage pool for a particular access pattern and level of data protection. You assign a profile to a pool to define the attributes of the pool.
An enclosure containing disks. A tray with dual RAID controllers is called a controller tray; a tray without a controller is called an expansion tray.
The total amount of data in a stripe, representing the block size multiplied by the number of disks in the stripe. See also striping.
A storage allocation method in which data is stored over a series of disks or virtual disks, improving performance.
The recipient of initiator commands, usually a volume.
See remote CLI client.
See storage tray.
A collection of physical disks that share a RAID level and disk type (FC or SATA). Virtual disks are created as a result of an option during the development of a volume.
A container in which applications, databases, and file systems store data. Volumes are created from virtual disks, based on the characteristics of a storage pool. A volume is seen by a Data Host as a single disk.
See snapshot.
World Wide Name. A unique 64-bit number assigned by a recognized naming authority such as the IEEE that identifies a connection (device) or a set of connections to the network. The WWN is constructed from the number that identifies the naming authority, the number that identifies the manufacturer, and a unique number for the specific connection.
