I give the replication feature a 10 out of 10. The GUI for snapshot replication gives you a lot of flexibility to schedule asynchronous replication, bandwidth control, and disk-rebuild resource allotment.
High Availability is a 10 out of 10, too, for having redundant RAID controllers per tray and the ability to build an HA Multi-Site.
I also like the easy setup of these units. We get project bids with zero lead time and when you have to build out a facility and you have a deficit of time to do so, it helps to have a quick and easy install and intuitive GUI. Running updates on these systems is nice and easy. The support staff are also very good.
My update for 5/31/2016:
Current Config:
Our Horizon View, VMware, Atlantis, ProfileUnity, Liquidware, and McAfee Move (Agentless) software versions are generally the same. Slight version upgrades. Our big change for the first half of 2016 is that we purchase our first CS250-HC Hybrid (2 SSDs). Logon times have improved 40 to 45 seconds. The VSA for the CS250 is on a separate cluster since the CS240 has such different storage requirements. we are now just under 100 VDI users and quickly deploying now that the new hardware is in place. 400 UDI users by the end of 8/2016.
We still planning a 2nd half 2016 DR deployment, DMZ, and load balancers.
Biggest Hurdles:
Same as before - Training the helpdesk
