You guys are just amazing, starting from the stability, backporting, bug correction, community support to documentation. I really don't have nothing to complain, only to thanks. What I was trying to says its, I was not asking a list of ALL the hardware drbd run's fine, because it should go fine everywhere. What I was trying to says it's, imagine in the next week, I will deploy a new cluster with drbd, I will need 10Gbit NIC's, because I have a lot of I/O bandwidth. If there is a list with a couple of 10Gbit NIC's that works, I will simply forward it to my manager and ask him to buy one of that ones. If he would like to buy a shipper one, and things go wrong, don't blame on me, or even on DRBD or Linbit... :). Would be nice to have that list, that's only. -- Igor Neves<igor.neves at 3gnt.net> 3GNTW - Tecnologias de Informação, Lda SIP: igor at 3gnt.net JID: igor at 3gnt.net ICQ: 249075444 MSN: igor at 3gnt.net TLM: 00351914503611 PSTN: 00351252377120 -------------- next part -------------- An HTML attachment was scrubbed...
