I've heard of 40Gbps NAS (by Cisco) :
a) is supporting/managing/provisioning new storage easier than conventional SAN ?
b) how does in perform in terms of IOPS compared to say an 8Gbps SAN (VMAX)?
c) on the servers end, do we need to install 10Gbps NIC or what types of
NIC is needed
d) under what situations is such a NAS preferred over SAN ?
e) if we are doing VTL backup, does such a NAS support it?
f) does such a NAS support SSD, Fiber & SATA disks with auto-tiering?
