I got tasked with the job of finding a server that can have an intel sandy bridge processor today. So I looked up a bunch of servers and for example, the HP DL360 Gen8 supports Intel® Xeon® E5-2600 v2 processors. The Gen 6 version of the same server, from the spec sheet, just says Intel 5500/5600 Series Xeon® Processors. So I am trying to reconcile two different name/types. Now from the sandy bridge wiki page I can see that only the Xeon E3, E5 is listed. So I guess this means the Xeon 5500/5600 isn't sandy bridge?
I am sorry to hear you are having problems with this configuration but let me help you.
I recommend you accessing at the following link so you can search for the processors you are interested in and compare them using the Comparison Tool in the website:
