Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 9)

PowerVault NAS Cluster Minimum System Requirements
PowerVault NAS SCSI 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 1-6 lists the hardware requirements for the cluster nodes.
Table 1-6. Cluster Node Requirements
Component Minimum Requirement
Cluster
nodes
Two homogeneous (identical) PowerVault 770N or 775N NAS systems that support clusters in homogeneous
pairs.
Processors One or two processors on both cluster nodes.
NOTE: Both cluster nodes must be configured with the same number of processors.
RAM At least 512 MB of RAM installed on each cluster node.
RAID
controllers
One of the following PERC RAID controllers installed in each system for the cluster's shared storage:
PERC 3/DC
PERC 4/DC
Up to two PERCs per cluster node may be used for the cluster's shared storage.
Two disk drives are required for mirroring (RAID 1) and at least three disk drives are required for disk
striping with parity (RAID 5).
Network
adapters
Two or more network adapters installed in each PowerVault NAS system for the node-to-node cluster
interconnect.
If two network adapters are not installed in the PowerVault 770N NAS system, you must install an additional
network adapter for the private network. PowerVault 775N NAS systems are preconfigured with two onboard
network adapters, which meets the minimum requirements.
NOTE: The network adapters must be identical on both systems.
NOTE: Dell and Microsoft support only the specific configuration described in the Dell PowerVault NAS SCSI
Cluster Platform Guide.
Private
network
cables
If you are using Fast Ethernet network adapters for the private network, connect a crossover Ethernet cable
between the network adapters in both cluster nodes.
If you are using Gigabit Ethernet network adapters for the private network, connect a standard Ethernet cable
between the network adapters in both cluster nodes.
