Raid Levels For Replication Repository Virtual Disks; Primary And Secondary Virtual Disk Pairs - Dell POWERVAULT MD3600F Owner's Manual

Other information about replication repository virtual disks include:
• Specifying that replication repository virtual disks be created from
unconfigured free capacity on the disk group, or creating a new disk group
and its member replication repository virtual disks from unconfigured free
capacity on the storage array.
NOTE:
be deleted without disabling the Remote Replication premium feature.
• Default names of the replication repository virtual disks are Replication
Repository 1 and Replication Repository 2. These names cannot be changed.
• The activation process creates replication repository virtual disk with
identical capacity. In a dual RAID controller module storage array, the
default capacity for each replication repository virtual disks is 128 MB per
controller (requiring a total of 256 MB in the RAID group). This default
capacity cannot be modified.

RAID Levels for Replication Repository Virtual Disks

If replication repository virtual disks are created from unconfigured free capacity
on the storage array, you can select a RAID level for the disk group of either RAID
1/10, RAID 5, or RAID 6. However, if the replication repository virtual disks are
created from an existing disk group, RAID levels are not user configurable.

Primary and Secondary Virtual Disk Pairs

After the Remote Replication feature is activated and configuration of the FC
fabric, individual virtual disk replication pairs are be created. Up to 16
replication virtual disk pairs can be established. Each pair consists of a
primary (online) virtual disk and a secondary (offline) virtual disk, both of
identical capacity. During operation, primary and secondary roles can be
interchanged to test the replicated data sets without breaking the
relationship. Independent copies may be created by deleting the relationship,
in which case both virtual disks are available online to their configured hosts.
