IBM sells the 9210-8i as the ServeRAID M1015, available at Newegg for $320 (way over priced as with all things Big Blue). IBM adds optional RAID5/50 fakeraid to the BIOS with an additional license key payment. The retail version of the 9210-8i is the LSI 9240-8i, available at Newegg for $265. However, the specs on the 9211-8i are the same, and the connector layout is better--front vs top. I recommend it over of the 9240-8i. And it's a little cheaper to boot, $240 vs $265, at Newegg: http://www.newegg.com/Product/Product.aspx?Item=N82E16816118112 9211-8i full specs: http://www.lsi.com/products/storagecomponents/Pages/LSISAS9211-8i.aspx Unless you need to use drives larger than 2TB the $155 Intel 1068E card is a far better buy at almost $100 less. If you need to connect more than 8 drives, get a 9211-4i and one of these Intel expanders for 20 drive ports: http://www.newegg.com/Product/Product.aspx?Item=N82E16816117207 This combo with run you ~$450, or $22.50/port for 20 ports. The 9211-8i runs $30/port for 8 ports. > p.s. Sory for the duplicate Stan, I couldn't figure out how to disable html on > my android mail client, and linux-raid bounced it. No need to apologize.
