Redundancy is established by installing separate data paths between the host and the storage array, in which each path is to one of the two RAID controller modules installed in the storage array. Redundancy protects the host from losing access to data in the event of path failure, because both RAID controller modules can access all the disks in the storage array.

Cabling PowerVault MD1200 Series Expansion Enclosures
You can expand the capacity of your PowerVault MD3600f series storage array by adding PowerVault MD1200 series expansion enclosures. You can expand the physical disk pool to a maximum of 120 (or 192, if enabled using Premium Feature activation) physical disks using a maximum of seven expansion enclosures.
Expanding With Previously Configured PowerVault MD1200 Series Expansion Enclosures
Use this procedure if your expansion enclosure is directly attached to and configured on a Dell PowerEdge RAID Controller (PERC) H800 adapter. Data from virtual disks created on a PERC H800 adapter cannot be directly migrated to a PowerVault MD3600f series storage array or to a PowerVault MD1200 series expansion enclosure connected to a PowerVault MD3600f series storage array.
CAUTION: If a PowerVault MD1200 series enclosure that was previously attached to PERC H800 adapter is used as an expansion enclosure to a PowerVault MD3600f series storage array, the physical disks of the expansion enclosure are reinitialized and data is lost. You must backup all data on the expansion enclosure before attempting the expansion.
To attach previously configured PowerVault MD1200 series expansion enclosures to the PowerVault MD3200 series storage array:
1Back up all data on the expansion enclosure(s).
