Note:
The maximum number of virtual disks is 512. One virtual disk can be presented
to multiple hosts. The maximum size of a virtual disk is 2047 GB. The maximum
number of presentations is 8192.
There are three types of virtual disks:
■
Active member of a virtual disk family
—
a virtual disk that is accessed by one
or more hosts for storage. An active member of a virtual disk family is
automatically created whenever a new virtual disk family is created. An active
virtual disk member and its snapshot(s), if one or more exist, constitute a
virtual disk family.
■
Snapshot virtual disk
—
a virtual disk that reflects the contents of another
virtual disk at a particular point in time. A snapshot operation can be done
only to an active member of a virtual disk family. The active virtual disk
member and its snapshots constitute a virtual disk family. A snapshot is
intended to be temporary.
Note:
A maximum of seven snapshots per virtual disk can exist at one time.
Business Copy EVA must be installed to enable the snapshot and Snapclone features of
the storage system.
■
Virtual disk Snapclone
—
a Virtually Instantaneous Snapclone is a virtual disk
that is an exact copy of another virtual disk at a particular point in time. Only
an active member of a virtual disk family can be snapcloned. The snapclone,
like a snapshot, reflects the contents of the source virtual disk at a particular
point in time. Unlike the snapshot, the snapclone is an actual clone of the
source virtual disk and becomes an independent active virtual disk member of
its own disk family when all the data is replicated. A snapclone can be
presented to hosts and used for storage while the data is replicating.
Within the Virtual Disks folder in the Navigation pane are Vdisk families. You can
click on any one of the Vdisk families within the virtual disk folder to see the
properties page for a specific Vdisk family.
The Virtual Disks folder is accessible using the folder structure in the Navigation
pane, as shown in
