Glossary
VLP
ISP which has neither a host nor a device port. Some central management
processes, in particular
VLM
und
PLM
, run on this ISP. A CentricStor
system can contain two VLP-ISPs. The central management processes
then only run on one of these, the
VLP Master
. The other, the Standby VLP
(
SVLP
), is inactive except for monitoring the VLP Master.
VTC
In the small CentricStor models VTC and SBU this is the only ISP and
combines the attributes of the
ICP
,
IDP
and
VLP
. For the
TVC
the local
disks are configured to form a RAID10 instead of an external RAID system.

LV
A logical volume (LV) is a file which is stored temporarily in a Tape File System of the
Tape Volume Cache
(
TVC
) and stored permanently in a physical volume (
PV
). The
standard size in an
LVG
is 900 MB, but this can be selected in discrete steps: 2, 5, 10,
20, 50, 100 oder 200 GB.
No more than 500,000 LVs can be defined in a CentricStor system, the name of each
(
VSN
) being unique in the system.
