Easy to scope server
capacity for one
server failure.
The cluster node next in line for failover may not have
ample resources available to handle the additional
workload of the failed node.
Minimum System Requirements
NAS Fibre Channel cluster configurations require the following hardware and software components:
Cluster nodes
Cluster storage
Cluster interconnects (private network)
Client network connections (public network)
Operating system and storage management software
Cluster Nodes
Table 1-11 lists the hardware requirements for the cluster nodes.
Table 1-11. Cluster Node Requirements
Component Minimum Requirement
Cluster
nodes
Two supported PowerVault NAS systems running Windows Storage Server 2003, Enterprise Edition.
Processors At least two processors for each cluster node.
NOTE: Each cluster node must have identical processors.
RAM At least 512 MB of RAM installed on each cluster node.
NOTE: Each cluster node must have identical memory configurations.
HBAs Two Fibre Channel HBAs for each cluster node.
Dell recommends placing your Fibre Channel HBAs on separate PCI buses to improve availability and
performance.
See the Platform Guide for more information about supported NAS systems, specific HBA models supported
by the system, and PCI slot configuration guidelines.
NICs Minimum of two NICs: one NIC for the public network (client LAN connections) and another NIC for the
private network (cluster interconnect).
You must install identical NICs in each cluster node for the public and private networks.
RAID
controller
The operating system volume is located in a RAID 1 configuration on an internal RAID controller on each NAS
system.
Cluster Storage
Table 1-12 provides a list of supported storage systems and the configuration requirements for the cluster nodes and stand-
alone systems connected to the storage systems. Table 1-13 provides hardware requirements for the processor enclosures
(DPE and SPE).
