What is your gluster setup? Please share volume details where vms ate stored. It could be that the slow host is having arbiter volume.

I don't think it is related with iDRAC itself but some configuration is wrong or there is some hw error. Did you check battery of raid controller? Do you use disks in jbod mode or raid mode?

"Did you check the BIOS/Power settings? They should be set for high performance. Also you can try to boot "intel_idle.max_cstate=0" kernel command line option to be sure CPUs not entering power saving states.

I have a 3 host gluster replicated cluster that is providing storage for our RHEV environment. We've been having issues with inconsistent performance from the VMs depending on which Hypervisor they are running on. I've confirmed throughput to be ~9Gb/s to each of the storage hosts from the hypervisors. I'm getting ~300MB/s disk read spead when our test vm is on the slow Hypervisors
