How does the load/re-balancing process works in horizon view?

[Johan_DWI]

Hi, we work with linked clones located on local storage of several esx hosts.
Some esx hosts are much more powerfull (cpu and memory) and have much less stress handling a higher number of vdi's.

For the moment all esx hosts have around the same amount of vdi's.

From other posts/forums it seems that view will only take into account the available disk space to balance the vdi's over the different hosts. Is there a way to change this? e.g. Make cpu and mem count as well?

best regards

you can enable DRS on each cluster at vCenter level. DRS will make sure the VMs workload are balanced in the cluster by doing vmotions.

Hi Yezdi,

thanks for your reply!

If you activate DRS don't you risk having potential interuptions in a vdi sessions of an active user in case vcenter decides to do a vmotion on the vdi? Or could you potentially activate DRS in vcenter when executing a rebalance in view and then deactivate it again?

Not at all!

1. My recommendation is to enable HA on your cluster as with any virtualized workload. That's a key feature of vSphere and makes sense to have on.

2. For DRS, understand your workload a bit. How many hosts will you have? How many VMs? How tight is the consolidation?

VMware vSphere Distributed Resource Scheduler (DRS) is commonly used in today's virtualized infrastructures. It is considered to be best practice in server virtualization to enable DRS. To turn off Load Balancing based on resource usage, slide the bar all the way to the left, Conservative. This means DRS will action moves based on everything except resource imbalances between physical hosts.
