I have a Dell with HBA and currently running 12 x 6tb with OS (Core) on a SSD. I want to purchase a SLOG and ZIL for it as we want to use it as failover VM storage.
My plan is to get a PCIe NVME card and use that as the SLOG and ZIL on normal SSD storage. Given that we have limited slots on the R720, I assume I would need 2 of these for replication purposes. I believe after that I will be able to disable sync on NFS which should improve the NFS based storage in XCP?
Also, is it better to use ISCSI over NFS as XCP offers both. I'm new to ISCSI, have been using NFS for a long time. Any other recommendations considering that it would host VM's?
