My scenario is the following:
2 Citrix hypervisor 8.0 servers in HA mode.
2 QNAP TS-451 +, 8 GB RAM, 4 x Hard drive 2 TB.
I would like to use a QNAP as a primary with an ISCSI LUN to store all the high availability virtual machines of the Citrix servers and another QNAP as secondary to store the live replica of the ISCSI LUN of the primary QNAP, with all its virtual machines and without loss of information.
it's possible? What would be the best practice?
regards
What is the best practice to implement 2 QNAP replicating the VMs of 2 Xenserver cluster servers?

Sorry but Citrix Xenserver is just terrible for performance and people always end up blaming storage.

Contact Citrix to see if the QNAP models are certified for use. Contact QNAP for performance questions.

Use RAID and external backups. RAID will protect you from disk failure, keep your system running, and data accessible while the disk is replaced, and the RAID rebuilt. Backups will allow you to recover data that is lost or corrupted, or from system failure. One does not replace the other.

Here's the HCL. Found Citrix Hypervisor slow, even with SANs. Well that was my experience - just not worth the hassle over Hyper-V/ESXi. But maybe it's better now...
