FREENAS SERVER SETUP
Freenas 9.2.1.6
Asrock
motherboard
E3C224D4I-14S
Intel Xeon E1230V3 3.3GHz Processor
32GB Crucial memory CT2KIT102472BA186D.000 2x - 8GB DDR3-1866 ECC.
Hard Drives
1x Samsung 840 128Gb Freenas OS
Hitachi
7x HDS724040ALE640
7200 RPM
Switch Cisco 3750G
LACP enabled on two ports giving a 2Gb connection
I am new to the Freenas scene so read a few threads and decided to try it myself.
The items listed above are those used in my home Lab setup
The results so far from Freenas have been what I expected about 110MB/second.
What is confusing me is that people have been saying they get 300-400MB/second.
How on earth is that possible when a gig link can't support and I don't believe for a minute they are on a 10GB network?
When I come to create a ZFS volume it asks me about what type of Raid set I want
I choose RaidZ2 and select all my 7x 4TB disk drives but it complains this is not optimal performance. It appears it wants me to choose RaidZ3 but this looses me too much disk space. What is the issue with RaidZ2 with 7x 4TB drives is there really a performance issue?
I noticed you can create a SSD cache for Freenas what exactly is this for what advantages will it gain me over the transfer speeds I already get?
If the SSDs fail with the cache and log setup on them later on what happens then does it cause major issues?
I want to eventually setup AES encryption as my processors supports it but what's anyone's recommendation with doing ISCSI with about 10 targets on Freenas with encrypted ZFS is this doable?
