Slow iSCSI VMWare zvol

I guess this would be easier if I just put SFP+ in 10gbps networking?

Well, yes.

I've been seeing Dell 5524's on eBay now and then for as low as around $75. Gives you two ports of SFP+ 10G and 24 ports of 1G copper. You can also stack two of them to double your port counts (it uses HDMI to stack).

My kit is all Ubiquiti - so I'll probs go for Ubiquiti EdgeSwitch 16 XG - ES-16-XG

Since we have put the bottleneck problem to bed.

Can someone confirm if this is the best mirrored setup for performance, resilience/capacity?

is nobody going to mention sync writes? Granted this person with their extremely limited knowledge of storage systems would be best to leave such settings alone.

Also EXACLY how is your 4gb network achieved? Is this a LAGG to the switch? Are you simply using MPIO over 4 subnets? are you running 5gb ethernet and reserving 1gb of bandwidth on the interface in vSphere?

Please provide the output of lspci and ifconfig from your FreeNAS server.

Well... I did. In the second post. ;)
