Best Practice Array/Volume Size on Nimble AF40?

Hi, is there a best practice, sizing Nimble arrays/ volumes for vsphere 6.5?

Best regards

Re: Best Practice Array/Volume Size on Nimble AF40?

Hello,

Not really, a search on this forum will yield many results around the 10/15/20 VMs per datastore rule. Oh, and don't make your volumes any bigger than a few TB. Large multi-TB datastores are asking for trouble when thinking about snapshots, replication, and even performance.

i'd recommend to use VVols more than anything though.

I've been under the impression that the atomic test & set (ATS) primitive had obsoleted the 15-20 max VMs per datastore guidance.  Anyone seen updated information surrounding this?

Unfortunately not. There's plenty of blogs around, but here's a good one - it's old, but still relevant. http://www.boche.net/blog/2013/02/28/vaai-and-the-unlimited-vms-per-datastore-urban-myth/

There was a thread on Reddit recently which was a similar discussion point. This might be useful: https://www.reddit.com/r/sysadmin/comments/eeow4y/nimble_dhci_storage_allocation/fbxx1bp/?context=3
