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:
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.

No need to apologize.  Sh*t happens.
