We are in the process of trialing 2x Open-E DSS v7 for Active/Passive Fail-over.
We have followed the setup guide. Server's configuration is as follow:
* Intel Server Chassis
* Dual Intel Xeon CPU
* 32 Gb Ram
* 3 x 4TB HDD
* Dual 1gbit ethernet
* Dual 10gbit ethernet
Both Servers are identical
From what we can see replication is working well, the issue we have is when we try to create a new Virtual Machine in ESXi it takes over 3 hours to build whether it is from and ISO or Template.
What we have found is when we break the fail-over it improves the performance down to approximately 1 hour.
I feel the reason we are having this issue is because it is trying to create the VM at the same as it is trying to replicate the VM.
