Comment on Mem.MinFreePct and Memory Reclamation in vSphere 5 by Michael

Hi,
Good reading. Thanks for the info.
I know this is an old post but I do have some questions:
When “High” memory state is reached and Large pages are being broken into small, is this done for some VMs or for all of them?
When large pages will be used again? Only for new VMs that are powered on? Or only after server reboots?

Thanks.

Eyal,

I checked the link and found the paper to be still there. In any case, here is the exact link to the paper: http://www.vmware.com/files/pdf/techpaper/vmware-vsphere-virt-sql-vcdb-WP-EN.pdf

“If you have to sVMotion a vmdk on a SIOC enabled datastore when do you do it?”

**With VaaI – Any time you want since offloaded svMotion doesn’t go against it’s “quota” of I/O allowed by SIOC.
**No VaaI – Preferably at time when VM has low I/O requirements so that svMotion I/O doesn’t hog the “quota” of I/O allowed to it by SIOC and consequently, adversely affect the performance of the VM being svMotioned.

Great post!
