CPU resource sharing in RHEL5

Srinikalyan — Wed, 24 Mar 2010 08:26:16 GMT

Hi,
Is there any product or software in RHEL5 similar to HP's gWLM where I can share the resources (CPU) between the servers (bl460c blades)? My requirement is on the DR site we have one server for DR and another is for performance. In the normal scenario, performance should have more resources i.e. taking most of the CPU's from perf. env. In case of DR, the other way around.

Thanks,
Srini

It seems that gWLM itself already support linux: http://h20338.www2.hp.com/enterprise/cache/257279-0-0-225-121.html

If so, IMO, this is the best option for you.

Thanks for your response. But gWLM supports linux only if they are running as a guest OS on an HP Integrity Virtual Machine. In our case we have two independent servers.

I see.
If so, VMWARE-based infrastructure should provide similar functuonality, see http://pubs.vmware.com/vsp40/resmgmt/wwhelp/wwhimpl/common/html/wwhelp.htm#href=c_load_balancing_and_virtual_machine_migration.html&single=true .
(I don't think you can share CPUs between a few server w/o some virtual infrastructure)

Shalom Srini,

vmware, from vmware, or other virtualization packages does permit the assignment of CPU resources and priority to one machine or the other.

A standards based tool will be easier to administer in the scenario you envision.
