4 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
1.2 IBM Storwize V5000 Gen2 terminology
The IBM Storwize V5000 Gen2 system uses terminology that is consistent with the entire IBM
Storwize family and the IBM SAN Volume Controller. The terms are defined in Table 1-2. More
terms can be found in Appendix B, “Terminology” on page 819.
Table 1-2 IBM Storwize V5000 Gen2 terminology
IBM Storwize V5000 Gen2 term Definition
Battery Each control enclosure node canister in an IBM Storwize V5000
Gen2 contains a battery.
Chain Each control enclosure has either one or two chains, which are
used to connect expansion enclosures to provide redundant
connections to the inside drives.
Clone A copy of a volume on a server at a particular point. The
contents of the copy can be customized and the contents of the
original volume are preserved.
Control enclosure A hardware unit that includes a chassis, node canisters, drives,
and power sources.
Data migration IBM Storwize V5000 Gen2 can migrate data from existing
external storage to its internal volumes.
Distributed RAID (DRAID) No dedicated spare drives are in an array. The spare capacity is
distributed across the array, which allows faster rebuild of the
failed disk.
Drive IBM Storwize V5000 Gen2 supports a range of hard disk drives
(HDDs) and Flash Drives.
Event An occurrence that is significant to a task or system. Events can
include the completion or failure of an operation, a user action,
or the change in the state of a process.
Expansion canister A hardware unit that includes the SAS interface hardware that
enables the control enclosure hardware to use the drives of the
expansion enclosure. Each expansion enclosure has two
expansion canisters.
Expansion enclosure A hardware unit that includes expansion canisters, drives, and
power supply units.
External storage MDisks that are SCSI logical units (LUs) that are presented by
storage systems that are attached to and managed by the
clustered system.
Fibre Channel port Fibre Channel ports are connections for the hosts to get access
to the IBM Storwize V5000 Gen2.
Host mapping The process of controlling which hosts can access specific
volumes within an IBM Storwize V5000 Gen2.
Internal storage Array MDisks and drives that are held in enclosures that are part
of the IBM Storwize V5000 Gen2.
iSCSI (Internet Small Computer
System Interface)
Internet Protocol (IP)-based storage networking standard for
linking data storage facilities.
