I wanted to use RCU to build citrix presentation servers for production use, do you guys think that it is a good idea to use RCU/Flexclone for Production server? what is official line by NetApp?
if you guys please advise your suggestions and docs to read will be very helpful
Solved! See The Solution
Yes - Please use VMs deployed via RCU (FlexClone) for produciton use cases.
You should understand that Data ONTAP is a pointer based storage array. Snapshot backups, File Clones, & Data Deduplicaiton are all based on the same technology. Pointers for backup, zero cost provisioning, and storage efficencies over the life cycle of a data set.
If you have any additional thoughts arounf the use of RCU, you will find loads of discussion and comments here:
do you have any case studies which can show RCU/FlexClone works well with heavily utilised VMs like Citrix Servers? All I hear about is test and dev environment, also VDI environment. I trialled it out and seems to be wonderful technology
Absolutely. The VMs created by RCU will create pre-deduplicated virtual hard drives. The result is not only capacity savings, but speed improvements as well. This is because the NetApp storage controller cache is dedup aware.

Question for you Eric, this NetApps official line as I need to present some sort of doc to my boss where it says in black and white? so far all I found was can be used in Lab, development etc!
thanks in anticipation
Chris lays it out in this video...
I've asked some folks to provide more collateral for you as well.
In the mean time, here are some answers:
NetApp dedup is appropriate for production virtual server workloads (in fact it will boost performance).
NetApp file level FlexClone creates "pre-deduplicated" vmdk files.
The RCU leverages NetApp file level FlexClone to create space efficient virtual machine clones.
Hope this helps,
