NOTE:
RAID 0 and independent disks are possible but are not recommended for a
high-availability system because they do not offer data redundancy if a disk
failure occurs.

Introduction
Minimum Requirement
At least two NICs: one NIC for the public network and another
NIC for the private network.
NOTE:
It is recommended that the NICs on each public network are
identical and that the NICs on each private network are identical.
One controller connected to internal disks for each node. Use any
supported Redundant Array of Independent Disk (RAID)
controller or disk controller.
Two physical disks are required for mirroring (RAID 1) and at least
three are required for disk striping with parity (RAID 5).
NOTE:
It is strongly recommended that you use hardware-based
RAID or software-based disk-fault tolerance for the internal drives.
Minimum Requirement
One Dell PowerVault MD3000i RAID enclosure.
Up to two Dell PowerVault MD1000 expansion enclosures.
Two integrated hot-pluggable power supply/cooling fan
modules.
At least two physical disks in the PowerVault MD3000i RAID
enclosure.
In a switched-attached configuration, clusters and stand-alone
systems can share one or more PowerVault MD3000i systems.
