I'll second BeenGD,
I have deployed tegile HA2100 on two sites.
Site 1 - VMware View VDI: ~35, VM Servers: ~35.
Site 2 - VMware View VDI: ~50^, VM Servers: ~50
^ - hosted on FusionIO card because the site required an instant recompose.
No issues at all at Site 1 when the View is fully hosted there. Recompose will be a bit slower than FusionIO but that's normal.
I even carved it out a few TB to use as my daily Veeam backup repository and no performance being impacted.
Tegile support is TOP notch. They are very responsive even when you call them at midnight or 2 am. (I did test it once)
I wish VMware support is like that. Lol.
My only gripe is still the storage dashboard. They did make a big update just recently so it's way better than before but I still think Nimble wins on that part. But the engine I believe is better than Nimble.
Maybe ask for a POC on their smaller storage and test it out yourself?
Cheers.
