You should have mentioned this sooner, as there is a better solution than buying 3 of the 9211-8i, which is $239*3= $717. And you end up with one SFF8087 port wasted. Instead, get a 24 port Intel 6Gb SAS expander: http://www.provantage.com/intel-res2sv240~7ITSP0V8.htm $238.24 and the LSI 9240-4i, same LSISAS2008 chip as the 9211-8i: http://www.newegg.com/Product/Product.aspx?Item=N82E16816118129 $189.99 Total: $429 W/4 extra SFF8087 cables (assuming you already have 2): http://www.newegg.com/Product/Product.aspx?Item=N82E16816116093 $60 Total: $489 This solution connects all 20 drives on all 5 backplanes to the HBA, and will give you ~1.5GB/s read throughput with 20 7.2k RPM drives using md RAID 5/6, and ~800MB/s with hardware or md RAID10. You connect the SFF8087 of the LSI card to port 0 of the SAS exapander. You then connect the remaining 5 ports to the 5 SFF8087 ports on the 5 backplanes. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
