That's because the 9210* is...
"*Only available to OEMs through LSI direct sales."
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:

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.

No need to apologize. Sh*t happens.
