A common connection point for devices in the storage network. The hub may be unmanaged, IP-managed, or FC-managed. An unmanaged hub is passive in the sense that it serves simply as a conduit for data, moving the data from one storage resource to another. IP-managed and FC-managed hubs are intelligent, containing features an administrator can use to monitor the traffic passing through the hub and configure each port in the hub.

A zone set available for activating on a Fibre Channel fabric. See also active zone set, zone set.

A type of Fibre Channel management protocol. The most prevalent in-band protocol over Fibre Channel is SCSI Enclosure Services (SES). Contrast with out-of-band.

See HBA port group.

An identifier for a computer or other device on a TCP/IP network, written as four eight-bit numbers separated by periods. Messages and other data are routed on the network according to their destination IP addresses. See also virtual IP address.

A storage router implementing the Internet Small Computer Systems Interface (iSCSI) protocol (SCSI over IP) to extend access of a Fibre Channel fabric and attached storage devices to IP servers. Currently, CommandCentral Storage discovers only the Cisco SN 5420 iSCSI router.

A cabinet of disks.

See LUN.

A simple volume that resides on an extended partition on a basic disk and is limited to the space within the extended partitions. A logical volume can be formatted and assigned a drive letter, and it can be subdivided into logical drives. See also LUN.

A unique and discrete addressable unit or logical volume that may reside inside one or more simple or array storage devices. LUNs are exposed to the outside world through an addressing scheme presented to the host as SCSI LUN numbers. Each LUN has a unique device handle and represents a logical volume.

The creation of access paths between an addressable unit (AddrUnit) within a disk array and a port on the array. AddrUnits are storage volumes built out of the physical disks within the array. Array ports are connected to the SAN fabric and function as SCSI targets behind which the AddrUnits bound to those ports are visible.

The practice of enabling access to a particular addressable unit (AddrUnit) for a host on the storage network. This is done by creating an access control list
