Hi John,

Nice, useful information on ZFS tuning.

We are building a similar setup i.e. ZFS + XSAN and wanted to know a few more details.

Did you all do any OS level tunings like increasing TCP Buffers, Disk nr_requests, read_ahead etc.?
How many SSDs are you using for ZIL and Cache?
Did you all partition the same SSDs for ZIL and Cache or did you all allocate different disks for each?

Also are your clients on 10G NICs?
Were there any OS tunings on the client side?
Could you give some idea about the client configuration too?

Thanks and Regards,
