Questions about READYNAS 4200v2 and ESXI (optimal RAID format and iSCSI vs NFS)
I'm setting up a 4200v2 for use in a home lab setup as a datastore for ESXi v7U2 (free version). It has 12 Seagate Constellation ST4000NM0053 ES 4TB SATA 7.2K 6Gbps drives, an Intel Xeon X3450 proces...

Maybe set up one of each, and then benchmark them.

After a factory default and new setup, the device picked X-RAID 6 as the array format. Should I stay with X-RAID, or move to a FLEX-RAID 10 array with 6 disks in each set?
You should get faster writes with RAID-10 (though of course you will also get significantly lower capacity).
Another option is to include a RAID-10 SSD array.

I added a Supermicro AOC-STG-i2T Dual 10G Ethernet Network Adapter (which OS 6.10.5 recognized just fine). I plan on going direct to my HP Proliant DL380's dual 10gb ports with the two 10gb ports on the 4200v2 with an MTU of 9000.
Set up the ReadyNAS to use "round robin". That should give you the fastest speeds in the NAS->Proliant direction. If you can find the same mode on the Proliant, then use that.

I'm working on testing the speed now. SSDs are not an option, as I had already purchased drives for it.
Thanks for the response.
