Pros: No issues under Centos 6.5. Dedicated IPMI. i250-at supports VLAN filtering and iSCSI boot.

Cons: Usual lack of options in Supermicro's BIOS. Get a single-bit ECC error about once per week, but that could be one of the UDIMMs since RAM is maxed out at 32GB.

Overall Review: Has been in production 6 months as a Pacemaker cluster node without any issues.
