I just came across this GREAT PowerPoint presentation today, I wish I had it 6 months ago, it really helps you to clear the sky and understand many things before making the design and purchase decision.
At first, I got very poor performance when I was trying to svMotion a 20GB VM within the same Equallogic SAN between different volumes, it took over 20 minutes to complete, I thought there must be something wrong as I’ve already enabled VAAI.
After searching the net and discovered the problem is due to Different Block Size between the two volumes (1MB vs 2MB) that will actually disabled VAAI feature.
So choosing the volumes with the same block size, I was able to reduce the time by almost 10 times!!!
See attached graph, 15:22 to 15:42 is the one without VAAI, 15:50 to 15:52 is the one with VAAI.
In additional, I have implemented Storage I/O Control today and found Storage vMotion with VAAI isn’t affected by SIOC as the whole svMotion is offloaded on to the EQL array, so SIOC won’t really kick in, you may say svMotion with VAAI is “Out of Control ”, this is another great thing about VAAI!
Finally, I do think SIOC is one of the best feature in ESX 4.1 for many cloud hosting providers as they can finally meet their storage SLA now besides the CPU and memory.
It’s nice to have this compliment plug-in for your Equallogic and VMware vCenter.
EqualLogic Datastore Manager – Allows administrators to provision new Datastores, expand existing Datastores, and monitor storage usage in the VMware Datacenter.
Auto-Snapshot Manager/VMware® Edition 3.0 – Creates and restores Smartcopies of Hypervisor consistent Virtual Machines (VMs). Utilizes snapshots, clones, and replicas within PS Series group allowing for fast restoration or disaster recovery.
EqualLogic Virtual Desktop Deployment Tool – VMware View aware desktop provisioning wizard which allows the deployment of manual virtual desktop pools using array based space efficient thin clones and also allows the refresh of these pools.
Note: These tools can be launched from the Home screen of vCenter and also from the new context sensitive tabs and right-click menu options that are added with the plug-in.
Btw, I am also getting the Dell Management Plug-in for VMware very soon from my Dell account manager, can’t wait to try it!
