Hi Sanjay, I’ve built a rather large ACS Cloud with 13 zones all over the world, most of them use NFS for 95+% of VMs, with the largest running over 10,000 VMs without any issues.
It really depends on your use case and which storage array you use. I personally would use NFS as default, unless there’s need for super low latency with very high random IOPS.

If we go with nfs, is there any issue related to performance. Therefore, we are trying to host more then 2000 vms on. Thank you!

Personally I'd go NFS, then CEPH, then local storage as my options.

In terms of commercial offerings, if your thing is distributed and hyperconverged then Storpool or Linstor comes to mind. Last but not least, if you are ok with not having fail over, VMs on local storage (SSD, NVME) are the fastest, so you could offer several tiers of storage I guess to meet most needs. Additionally NFS can still be a great solution if you plan it right and it's easy to do and has very mature support in Cloudstack, it will likely be faster than CEPH in many circumstances. The above is very generic advice and you should do more research before committing to anything.
