CPU issues - New Server
Posted on 2011-02-10
I have 2 brand new servers, both have identical hardware. One of my two servers is having big issues with CPU constantly spiking spiking, and slowing down the machine. We've narrowed the issue down to system interrupts, but still cannot figure out what's causing the issue. Here's the specs:
SuperMicro server board X8QBE-F
Windows Server 2008R@ enterprise
128 GB RAM
Intel Xeon 7550 x 4 CPUs
I've gone back between the two servers and checked every single driver to ensure they are the same (including driver version). We see no difference with the exception of one thing (well two as one server has an external RAID box and controller, and that's on the working system). the difference is the problematic system has the "Composite Bus Enumerator" under system devices. Could this be what is causing issues? Any suggestions?
