In the BIOS of my server I have 2 X 2.26 quad cores, however in VMware I only see 2 cores per CPU ? Surely this isn't right?

BIOS

VMware

Processor Cores and Processor sockets should show as below:

Processor Sockets: 2

Cores per Socket: 4

Logical Processors 16

Hyper.. : Active

Answer - Cores set to dual, not all.

DUAL-Set

Visit your BIOS config page and check processor settings. Do you see a value of "4" for "Number of Cores per Processor"?

Also, can you provide the build number of your ESXi installation? This could also be a bug (less likely).

  • I am completely unsure and confused as to whether this is a valid answer or should be a comment. Following what I've recently been pointed at I should flag this and put it up as a likely candidate for being a comment on the OP. But as it stands I don't see any way to directly answer OP with anything that's closer to an answer than what you wrote here! You're confusing me ewwhite! – Reaces Aug 26 '15 at 11:51
  • It's probably BIOS, since Dell was known to ship some of these units with the wrong BIOS settings. But this is a Nehalem-era chip, so that would be 2009-ish. The history of the server could be helpful. Was it recently installed? Was it repurposed? Just not enough info in the initial question. – ewwhite Aug 26 '15 at 12:07
  • Yep, correct again ewwhite. I am still unsure why this is a function of a processor in the bios? What benefit does limiting the cores to a machine give exactly? Maybe just because of licensing? – StackUser_py Aug 26 '15 at 12:16
  • @Reaces Don't get hung up on the fact that it is phrased as a question, it still includes the information that answers the problem. – JamesRyan Aug 26 '15 at 12:19
  • @StackUser_py Sometimes people limit BIOS cores for licensing requirements. – ewwhite Aug 26 '15 at 12:20
