Brian,
Thanks for your input. When in production, each node will be Gigabit
connected directly to a router so thoughput shouldn't be an issue in the
event of a failure. As for the 1TB LUN, only about 300GB will be in use at
the outset, the rest is for growth. Your concerns, however, have not fallen
on deaf ears and such considerations will be discussed internally.
The LUNs are RAID-5 on a brand new EMC SAN.
