Can I use internal SSDs instead of SAN storage?

Yes, but there are some things you should know.  The bandwidth on internal SSDs is great, and it’s a cheaper option, but there are some serious limitations/considerations you should be aware of. There is no redundancy with internal SSDs.  If a drive dies, it’s dead and all information is lost.  If you use internal SSDs you lose the ability to do resource pooling - each VM must run on a single host and the associated internal SSD. This also prevents you from running hosts in an HA configuration on large clouds.  With internal SSDs you are limited to 1TB/host.  Our small cloud bundles use internal SSDs by default.
