hi tareef,
we use this since 1 year:
Mainboard Supermicro X8DT3
Chasis SC836
CPU 1xIntel Xeon 5550W
RAM 24GB (6x4GB)
Raid Controller Adaptec ICP Vortex 8165BR with BB 256 Cache
HDD 16x Western Digital 1TB Raid Edition 3
NIC Intel 10gbe CX4 Dual Port
Switch
2x HP 6400cl CX4
we only change our raidcontroller to areca.
because of a still not fixed adaptec driver and raid 6 error in open-e.
so dont use adaptec and raid 6 with open-e!!!
look at this thread
