Cluster Nodes

Table 1-1 lists the hardware requirements for the cluster nodes.

Table 1-1. Cluster Node Requirements

Component	Minimum Requirement
Cluster nodes	A minimum of two identical Dell™ PowerEdge™ servers are
	required. The maximum number of nodes that is supported
	depends on the variant of the Windows Server operating
	system used in your cluster, and on the physical topology in
	which the storage system and nodes are interconnected.
RAM	The variant of the Windows Server operating system that is
	installed on your cluster nodes determines the minimum
	required amount of system RAM.
HBA ports	Two Fibre Channel HBAs per node, unless the server employs
	an integrated or supported dual-port Fibre Channel HBA.
	Where possible, place the HBAs on separate PCI buses to
	improve availability and performance.
NICs (public and	At least two NICs: one NIC for the public network and
private networks)	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	One controller connected to at least two internal hard drives
controller	for each node. Use any supported RAID controller or disk
	controller.
	Two hard drives 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.

NOTE: For more information about supported systems, HBAs and operating system variants, see the Dell Cluster Configuration Support Matrices located on the Dell High Availability Clustering website at dell.com/ha.
