Server components

The Series 4000 server comes in four models: Hitachi NAS Platform 4040, Hitachi NAS
Platform 4060, Hitachi NAS Platform 4080, and Hitachi NAS Platform 4100.
Physically, models HNAS 4060 and HNAS 4080 are identical. To upgrade a model HNAS
4060 to a model HNAS 4080 requires the addition of a software license. From outside of
the chassis, model HNAS 4100 is identical to the other models--it shares the same ports
and connectivity.
Hitachi NAS Platform and Hitachi Unified Storage Series 4000 Hardware Reference
With the HNAS 4040 model, the switch is also required if there are
more than two RAID subsystems attached or if there are two RAID
subsystems attached.
All cluster configurations require an external Ethernet switch.
See Hitachi Vantara Support Connect for information about the 10
GbE switches that have been qualified for use with the system, and to
find out about the availability of those switches.
The server connects to a 10 GbE switch for connection with the public
data network (customer data network).
Also, a 10 GbE switch is required for internal cluster communications
for clusters of three or more nodes.
See Hitachi Vantara Support Connect for information about the 10
GbE switches that have been qualified for use with the server, and to
find out about the availability of those switches.
Hitachi Vantara requires dual 10 GbE switches for redundancy. In a
dual-switch configuration, if one switch fails, the cluster nodes remain
connected through the second switch.
