Hi, Anyway, if you'd go for 10G on 12K, don't use the E4+ 10G card, SIP/SPA is really the only option. If you'd go n x 1G and stability is a concern stick to E3 4xGE card, one of the best cards ever made by cisco, I have seen lots of problems on 10x1GE SPA, especially in pre 12.0.(32)S7, now it has been stable for quite some time
