Switch Cascading

When two or more Fibre Channel switches are cascaded, the switch management software combines the ports for all of
the switches that are linked.

Journaling File Systems And Remote Replication (Legacy)

When using a journaling file system, you cannot gain read-only access to a remote virtual disk. A journaling file system
does not let you mount the remote virtual disk in Windows NTFS. However, you can mount a snapshot of the remote
virtual disk, if available.
Prerequisites For Setting Up And Managing Remote Replication
(Legacy)
Before setting up remote replication between two storage arrays, ensure that:
• The Remote Replication premium feature has been activated.
• The local storage array contains two replication repository virtual disks (created during activation).
• The local storage array contains the primary virtual disk to be replicated.
• The remote storage array contains the secondary virtual disk to serve as the replication target, and:
– Both virtual disks are visible to a single management station; replicated disk pairs cannot be managed
on separate instances of the MD Storage Manager.
– The RAID level of the secondary virtual disk can be different than that of the primary virtual disk.
– The capacity of the secondary virtual disk (after creation and formatting) must be equal to or greater
than the capacity of the primary virtual disk.
• The storage arrays containing the virtual disks you want to replicate are connected to each other through a
Fibre Channel switch fabric and are accessible from a single management station.
If either the primary or secondary virtual disk does not exist, you must create it before proceeding with remote
replication setup. See Activating The Remote Replication Premium Feature And Creating Replication Virtual Disks
complete the necessary steps.
If all virtual disks are created, skip to
Activating The Remote Replication (Legacy) Premium Feature And
Creating Replication Virtual Disks
To activate the Remote Replication (Legacy) feature and create the two replication repository virtual disks required, you
can either:
• Activate the feature, then create the two replication virtual disks from the total unconfigured capacity on the
storage array, or
• Activate the feature, then create the two replication virtual disks from the unconfigured capacity in an already-
existing disk group
