December 9, 200916 yr i have this motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128377 and around 10 drives is a really crappy chopped up case. i was thinking about getting one of these two server chassis: http://www.norcotek.com/item_detail.php?categoryid=1&modelno=RPC-4020 http://www.norcotek.com/item_detail.php?categoryid=1&modelno=RPC-4220 i am just really unfamiliar with all the server connections. i kind of understand what a backplane is but was wondering if there are 4 or 5 sata drives going through a sas backplane would there be a throughput bottleneck. not that it matters because i dont even have sas on my mobo. i am pretty sure the first one is what i need but wanted some feedback before i purchase. thanks.

SAS connectors are what Infiniband technology uses and they are designed to up to 16 Gbps I believe. Each SAS port handles 4 SATA connections, so your theoretical bandwidth won't exceed 12 Gbps (4x3Gbps). Not to mention you have drives that would be able to supply a sustained 3Gbps stream anyway. Even you you had a drive like this, I doubt any of your applications will saturate a 3Gbps link. Also you don't have to use controllers with SAS connectors, just buy a SAS-to-SATA break-out cable (1 SAS to 4 SATA). I believe Newegg sells cheap Norco break-out cables for those cases.
December 9, 200916 yr Author ok, thats what i assumed but really couldnt find much of an answer. thanks.
December 9, 200916 yr You need what are called Multi-lane Internal (SFF-8087) Serial ATA breakout cable, reverse. Fans out from the Multi-lane (SFF-8087, drive/backplane side) into four (4) discrete SATA connection to the controller. They must be reverse or they wont work.
