Hello everyone.
I plan on building another freenas server for my veeam backup needs.
i've been using a freenas setup for more than a year, and it's been fine, haven't had any serious issues with it.
But now, since it'll be a new thing, i've started digging a little more and i would like to do it right from the start.
Hardware-wise:
Dell R510 (12x3.5 chassis)
Dual L5630
32 GB ram
Will start with a raidz2 pool of 6 x 3TB WD Reds
Usage: Veeam B&R running on windows.
I've tried connecting from the veeam machine to freenas using cifs/nfs/iscsi, and i settled on iscsi (due to initial performance tests-basically the nfs implementation in windows has abysmal performance, cifs is somewhat decent, while iscsi is wirespeed).
This freenas server will not be used for anything else but those backups, which will be made using "Incremental" /w syntethic fulls. with 3 restore points on disks.
That means the the iscsi disk will contain 1 big file (100-500GB) + and 3 smaller files (<5GB) for each job, and there are currently about 20 jobs.
Now, that's the background(also worthy of mentioning is i'm using 1 gbps network).
Apparently there's an issue with high fragmentation for this type of scenario (currently looking at 33% FRAG on a similar server), and also i was planning on making one big iscsi disk that will probably fill all vdev, making freenas complain about pool usage from the start.(although currently i will be using less than 30% of the ~12 TB i will be getting from 6x3TB raidz2).
Given this pattern usage, any recommendations for the new setup?
Thank you for your time.
