We have just upgraded three DL580 G7's that are model 584084-001 to Xeon E7-4870 processors. We found that what mattered in our environment was the revision of the main system board (not the CPU board/tray or SPI riser). After reading that last response, I checked iLO to verify all of our PAL versions. We do have one server that is running 4 E7-4870 ...
This can not be answered because it depends on what you do application wise. Generally on an application level you do not care about those - you care about application level metrics (average response time per request, to be "simple").
Yes, this is possible, but currently only with the largest instances of some the newest families using the Intel Xeon E5-2666 v3: c4.8xlarge d2.8xlarge m4.10xlarge The EC2 documentation provides examples of how to do this on Linux. Basically it boils down to limiting the maximum sleep state to C1: kernel /boot/vmlinuz-... [...] intel_idle.max_cstate=1 ...
Like ewwhite notified it, I just ignored a serious compatibility issue. I finally got my hands on a 643086-B21 CTO model, fitted with two E7-8837 on PROC1 & PROC2. Sequential test done (I,J are E7-8837, SLC3N, 130W TDP): 1) PROC1=I, PROC2=J, PROC3=X, PROC4=X, POST=TRUE (E7 dimm cartridges) 2) PROC1=A, PROC2=B, PROC3=C, PROC4=D, POST=TRUE (E7 dimm ...
