Redundant And Non-Redundant Configurations; Cabling Powervault Md3060E Expansion Enclosures; Expanding With Previously Configured Powervault Md3060E Series Expansion Enclosures - Dell PowerVault MD3660f Deployment Manual

• Dual path data configuration — A dual path configuration allows you to connect a maximum of four hosts.
You choose the data configuration based on:
• Number of hosts required
• Level of data redundancy required

Redundant And Non-Redundant Configurations

Non-redundant configurations are configurations that provide only a single data path from a host to the storage array.
This type of configuration is only recommended for non-critical data storage. Path failure from a failed or removed cable,
a failed HBA, or a failed or removed RAID controller module results in loss of host access to storage on the storage
array.
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.
NOTE: For detailed information about all cabling configurations including direct and SAN-attached hosts, cabling
for remote replication environments, the use of zoning, and HBA installation, see
the Dell MD3660f Series Storage Array , at support.dell.com/manuals.

Cabling PowerVault MD3060e Expansion Enclosures

You can expand the capacity of your PowerVault MD3660f Series storage array by adding PowerVault MD3060e
expansion enclosures. You can expand the physical disk pool to a maximum of 120 (or 180, if enabled using Premium
Feature activation) physical disks using a maximum of two expansion enclosures.

Expanding With Previously Configured PowerVault MD3060e 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 MD3660f Series storage array or to a PowerVault MD3060e Series expansion enclosure connected to a
PowerVault MD3660f Series storage array.
CAUTION: If a PowerVault MD3060e Series expansion enclosure that was previously attached to PERC H800
adapter is used as an expansion enclosure to a PowerVault MD3660f 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 MD3060e Series expansion enclosures to the PowerVault MD3660f Series
storage array:
After the PowerVault MD3060e Series expansion enclosures are online, they can be accessed as a part of the storage
array.
1. Back up all data on the expansion enclosure(s).
2. Upgrade the expansion enclosure firmware to the latest version available at support.dell.com while the enclosure
is still attached to the PERC H800 controller.
Windows systems users can reference the DUP.exe package and Linux kernel users can reference the DUP.bin
package.
3. Ensure that the storage array software is installed and up to date before adding the expansion enclosure(s).
