Interface on the DC2 and DC4 drive cages through which the node software communicates to the cage enclosure services controller to obtain enclosure and cage status and control the cage behaviors. A detectable system occurrence. To present a virtual volume to a host. Exporting makes a volume available to a host by creating an association between the volume's name and a LUN (logical unit number) for the specified host and port. Drive type: either Fibre Channel or Serial Attached SCSI (SAS). With regard to drive types and drive capacities, the abbreviation FC applies to Fast Class. With regard to ports, the abbreviation FC applies to Fibre Channel only. Fibre Channel Arbitrated Loop. A fast serial bus interface standard used to connect storage devices to servers. A Fibre Channel PCI host bus adapter (HBA) located in a controller node. The Fibre Channel adapter connects a controller node to a host or to a drive chassis. A virtual volume (snapshot) with a set amount of user space and for which snapshot administration space and snapshot data space draw resources from a Common Provisioning Group (CPG). A network adapter located in a controller node. The Gigabit Ethernet adapter connects a controller node to a network in order to transfer data via the network. To increase the size of a virtual volume or CPG. The unit of storage space by which the system creates and allocates additional logical disks to a Common Provisioning Group (CPG) when the volumes in that CPG require additional resources. The minimum growth increment varies according to the number of controller nodes in the system (from 8 GB for a two-node system to 32 GB for a eight-node system). An optional setting that enables you to specify the maximum size to which a CPG can grow. An optional setting that enables you to specify the size at which the system alerts you to the amount of CPG growth. A path or set of paths, defined as either WWN or iSCSI names, to one or more ports on a system. The name of the host and the list of the paths (WWN or iSCSI) assigned to the host, if any. If you remove all the paths assigned to the host, the host name becomes the host definition. A VLUN template that allows a specified host connected to any port to see a virtual volume as a specified LUN (logical unit number). A data-protection solution that provides restore operations for a variety of platforms, such as Oracle, SQL Server, Exchange, and more. Software that enables you to create and continually update backup remote copies of virtual volumes and use those copies for disaster recovery, if necessary. The utility that enables the system to reallocate space usage in order to take advantage of additional resources, such as added hardware or updated CPGs. The System Tuner identifies underused chunklets and overused volumes, and balances the usage. Software that enables you to create a virtual volume that allocates resources from the CPG on demand and in small increments. Software that enables you to create virtual copies (aka snapshots) of virtual volumes. To create a virtual copy, the system uses the copy-on-write technique, which creates an up-to-date snapshot at the same time as data is written to the host. Software that enables you to create distinct domains with domain-specific users and objects. 88 Glossary

drive mount
A metal bracket used to secure a physical disk to a drive magazine. Each disk must be secured
by two drive mounts.
encryption key
A cryptographic key that is not exposed outside of the drive itself. The encryption key is used to
encrypt and decrypt all data stored on a drive.
ESI
Enclosure Services Interface. Interface on the DC2 and DC4 drive cages through which the node
software communicates to the cage enclosure services controller to obtain enclosure and cage
status and control the cage behaviors.

A detectable system occurrence.
export
To present a virtual volume to a host. Exporting makes a volume available to a host by creating
an association between the volume's name and a LUN (logical unit number) for the specified host
and port.
Fast Class
Drive type: either Fibre Channel or Serial Attached SCSI (SAS). With regard to drive types and
