ATM the Arista is may favourite. For the dual 10GeB NICs I tested the Intel X520-DA2 and the Mellanox ConnectX-3. My favourite is the Intel X520-DA2. -martin Am 07.11.2012 22:14, schrieb Gandalf Corvotempesta: > 2012/11/7 Martin Mailand : >> I have 16 SAS disk on a LSI 9266-8i and 4 Intel 520 SSD on a HBA, the node >> has dual 10G Ethernet.
