Depends on your expander. You can find more card examples in the hardware guide.OK Thanks.
What's the best card I can get for the amount of drives?

We've done it without lz4. It wasn't that great. See my posts earlier in the thread.On the sekond HBA, wich has 30 disks, can you do a riad 10 (striped mirrors ) and leave lz4 compresion on.
What model are the Intel NIC's? Do you have multiple interfaces on the FreeNAS target and Windows initiator or are you configured to only use one 10Gbe interface on each box?
There is another thread with a user having iSCSI issues with those same NIC's....maybe a coincidence, but interesting nonetheless. From an elevated command prompt on the initiator, what is the output of "mpclaim -s -d" and then "mpclaim -s -d num" where num is the disk number from the previous command, i.e. "mpclaim -s -d 1" for Disk1.
We're using Intel X540-T2 10GBE adapters
I wouldn't even worry about the network until you get reasonable performance locally. If dd is slow to read and write, nothing at the network side is going to make it better.
What SSDs are you using? If you create a pool without SSDs is it still slow?
My guess is that the Highpoint Rockets are the bottleneck. Never used them with FreeNAS because I had so many problems with them before FreeNAS. I know some people swear by them but I've pretty much only sworn at them.
Cheers,
Matt
