A disk that serves as a hot-spare within an array as part of the storage pool; a reserve disk that can be made available to all virtual disks within an array. See also hot-spare.
block
The amount of data sent or received by the host per I/O operation; the size of a data unit.
capacity
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.
CLI
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.

data host
Any host that uses the system for storage. A data host can be connected directly to the array or can be connected to an external switch that supports multiple data hosts (SAN). See also host.
data path
The route taken by a data packet between a data host and the storage device.
direct access storage (DAS)
A storage architecture in which one or two hosts that access data are connected physically to a storage array.

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.
Fibre Channel switch
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.
field-replaceable unit (FRU)
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.
FRU
See field-replaceable unit (FRU).
GUI
Graphical user interface. Users access the GUI through a web browser.
HBA
host
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.
host bus adapter (HBA)
A controller board on the server that allows the server to attach to external storage. See also initiator.
host group
A group of hosts with common storage characteristics that can be mapped to volumes. See also host.
hot-spare
The drive used by a controller to replace a failed disk. See also array hot-spare.
in-band traffic
System management traffic that uses the data path between a data host and a storage device. See also out-of-band traffic.
initiator
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 host bus adapters (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.
IOPS
A measure of transaction speed, representing the number of input and output transactions per second.
LAN
Local area network.
logical unit (LUN)
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.
LUN
See logical unit (LUN).
MAC address
See media access control (MAC) address.
management host
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 GUI or with a remote thin-scripting client to access the SSCS CLI commands.
master / alternate master
A design for reliability that uses redundant configuration. Array configurations share master/alternate master configurations: each array configuration has two controller trays that are grouped as one host. In each case, the master component uses the IP address and name. If the master fails, the alternate master assumes the IP address and name and takes over the master's functions.
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.
multipathing
A design for redundancy that provides at least two physical paths to a target.
out-of-band traffic
System management traffic outside of the primary data path that uses an Ethernet network. See also in-band traffic.
PDU
See power distribution unit (PDU).
pool
See storage pool.
power distribution unit (PDU)
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.
profile
See storage profile.
provisioning
The process of assigning storage to hosts.
RAID
Redundant array of independent disks. A configuration in which several drives are combined into a single virtual drive to improve data availability. Also called a RAID set or a RAID group.
RAS
Reliability, availability, and serviceability.
remote CLI client
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.
remote monitoring
Monitoring of the functions and performance of a hardware system from a location other than where the hardware resides.
remote support
The software management host uses Sun Remote Services Net Connect 3.1 software to communicate problems with Sun service.
SAN

site LAN
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.
snapshot
A copy of a volume's data at a specific point in time.
SSCS
Sun Storage Command System, the CLI that can be used to manage the array.
storage area network (SAN)
An architecture in which the storage hosts are connected to each other to increase data availability and storage utilization.
storage domain
A storage partition created through the mapping of initiators to hosts and the mapping of volumes to hosts or host groups. Also called a LUN map set.
storage pool
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.
storage profile
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.
storage tray
An enclosure containing disks. A tray with dual RAID controllers is called a controller tray; a tray without controllers is called an expansion tray.
stripe size
The total amount of data in a stripe, representing the block size multiplied by the number of disks in the stripe. See also striping.
striping
A storage allocation method in which data is stored over a series of disks or virtual disks, improving performance.
target
The recipient of initiator commands, usually a volume.
thin-scripting client
See remote CLI client.
tray
See storage tray.
virtual disk
A collection of physical disks or logical extents that acts as one disk to the hosts and initiators that have access to it. All storage on the disk must share the same storage characteristics as defined by profiles.
volume
A fixed amount of storage, not limited by the physical device. A disk can have more than one volume, and a volume can span more than one disk. Applications that use volumes do not need to be aware of physical storage locations, because the management software maps the virtual address to the physical address.
volume snapshot
See snapshot.
WWN
World Wide Name. A unique 64-bit number assigned by a recognized naming authority such as the Institute of Electrical and electronic engineers (IEEE) that identifies a connection (device) or a set of connections to the network. The World Wide Name (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.
