I've got a few X1028A-z cards in our blade servers and they work great under Solaris 10 (but a serious bug under ESX 3.5 - another forum thread covers that). They also seem to work fine under Windows 2008 R2, except I cannot determine if the supplied Windows driver supports 802.3ad link aggregation (LACP). We'd like to test this while we have demo Cisco Nexus gear on hand. The docs simply refer to Solaris (which is easy). Anybody know?
