Introduction 9
Cluster Nodes
Table 1-1 lists hardware requirements for the cluster nodes.
NOTE: For more information about supported systems, HBAs, and operating system
versions, see the Dell Cluster Configuration Support Matrices at dell.com/ha.
Table 1-1. Cluster Node Requirements
Component Minimum Requirement
Processor At least one processor for each cluster node.
Cluster Nodes A minimum of two identical PowerEdge systems.
RAM At least 1 GB RAM on each cluster node.
Host Bus Adapter
(HBA) ports
Two Fibre Channel HBAs per node, unless the server employs an
integrated or supported dual-port Fibre Channel HBA.
Network
Interface Cards
(NICs)
(public and
private)
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.
Internal Disk
Controller
One controller connected to internal disks for each node. Use any
supported Redundant Array of Independent Disks (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 recommended that you use hardware-based RAID or
software-based disk-fault tolerance for the internal drives.
