Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 10)

Table 1-7 provides the minimum requirements for the shared storage system(s).

Hardware
Component
Minimum Requirement
Shared storage
system(s)
Up to four PowerVault 21xS or 22xS enclosures (for the shared disk resource) with the following
configuration:
Two SEMMs for each PowerVault 21xS
Two EMMs for each PowerVault 22xS
Redundant power supplies connected to separate power sources
At least two SCSI hard drives in each PowerVault 21xS or 22xS enclosure to support hardware-
based RAID functionality
Currently, MSCS supports only the Windows NT File System (NTFS) format for the shared storage
system.
Two volumes are the minimum requirement for an active/active cluster configuration (where the
active nodes process requests and provide failover for each other)
See " Configuring Active and Passive Cluster Nodes " for more information on active/active and
active/passive cluster configurations.
Two 1-, 4-, 8-, or 20-m SCSI cables for each PowerVault 21xS or 22xS storage system in the
cluster
Cluster Interconnects (Private Network)
Table 1-8 provides the minimum requirements for the cluster interconnects (private network).

Hardware
Component
Minimum Requirement
Network
adapters
Any network adapter supported by the system for each cluster node. The network adapters for the private
network must be identical and supported by the system.
NOTE: Dual-port Fast Ethernet network adapters are not recommended for simultaneous cluster connections
to the public and private networks. When you configure the network adapter in MSCS Setup to All
Communications, the public network can provide redundancy for node-to- node traffic in the case of a
failure in the private network segment.
Ethernet
switch
(optional)
One Ethernet switch for the private network (cluster interconnect).
Ethernet
cables
One standard or crossover Ethernet cable.
Standard Ethernet cable (not included with the Dell Cluster kit) connects two copper Gigabit Ethernet
(1000 BASE-T) network adapters.
Crossover Ethernet cable connects two fast 100 Mb/s Ethernet network adapters.
Ethernet
switch
cabling
(optional)
Additional Ethernet cables (not included) may be used to attached to an Ethernet switch for the public
network (client connections) and private network (cluster interconnect).
