direct access storage (DAS)

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.

expansion tray

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.

failover and recovery

The process of changing the data path automatically to an alternate path.

fault coverage

The percentage of faults detected against all possible faults or against all faults of a given type.


See Fibre Channel (FC).

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.


See field-replaceable unit (FRU).


See host bus adapter (HBA).


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 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.


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.


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 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.

out-of-band traffic

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.

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.


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.

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 remote management host uses Sun Remote Services Net Connect 3.1 software to communicate problems with Sun service.


See storage area network (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.


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.

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 a controller is called an expansion tray.

See storage tray.

virtual disk

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.

volume snapshot
