HP BL660c vs Dell M820 – A Comparison

If you are a recurring reader to this blog, you’ll know that I work for Dell (1 year as of August 15) which makes me a bit bias toward Dell.  However, with the recent announcements of 4 socket blade servers based on Intel’s E5-4600 processor by HP and Dell, I thought it would be interesting to see how they line up.  With the attempt to be unbiased, I’ve listed everything I thought was relative about both servers so that you, the reader, could make your own decision about which server would work best in your environment.  I welcome any feedback, thoughts or comments below.  The data below is from HP and Dell’s websites and is current as of 8.14.12.

Updated 8.15.12 – Changed bottom CPU offering on Dell (originally omitted.)  Added PDF version of this table.
