Hi T_matz,
It is really strange. I have one of these Intel X540-AT2 (rev 01). It is working fine, I really like about this card is that it has two controller.
But I'm not getting more than 235mbps, do anyone have a suggestion to get beet better performance out of this config? my expatiation around 900 to 1000mbps.
This is my test server config Intel® Xeon® CPU E5-4650 0 @ 2.70GH, DDR 32GB ECC, Intel X540-AT2 (rev 01) 10G, Seagate ST12000NM002G 12 TB SAS x12, Parity 2x12TB, Cache 2x1TB SSD.
