ESXi 4.x and 5.x and Diskeep
I have two ESXi servers running 4.1 and will be moving to 5.x very soon. Both servers have local storage. I have seen advertisment for Diskeeper on ESX servers. I've used Diskeeper on Windows servers but never on a Vmware ESX server. Is this a god idea. I thought a Linux OS could get fragmented like a WInodws OS. Wouldn't running Diskeeper increase I/O usage?

Can it work on ESXi ???
We use the v-locity product with good results, defragmenting, and also reclaiming used space.
I'm intrigued - as it runs at the hypervisor level, what impact on performance is there?
ASKER
hanccocka, you are using Diskeepers v-locity on ESX or ESXi??
Yes, always, we involved with V-locity Beta, it's now released.
Both ESX and ESXi.
The reclaim storage function I believe is unique to V-locity.

I guess I new thought of Linux OS's geting fragmented..
Also I'm confused at how you can install Diskeeper on ESXi since it's stateless

It's installed on the VMs!

Ahh..
I thought this was something that could be installed on the ESX/ESXi host. How does v-locity differ from the regular diskeeper

Granted, it's from the vendor, but it does discuss performance.
Personally, I'm not a massive fan of automated defragmentation on servers. Also, I'm not sure how well this would cope with thin provisioned disks.
And digging around, there appears to be a few comments suggesting it can interfere with backups.
