• Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
    Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.

Need more speed!

I've got 24x2TB SAS drives. I'm getting 193MB/s out of my setup (with about 10 VMs idling). 40 gig NICs are getting dirt cheap. I wants them. Ain't no point to buying them when I can't saturate a 10 gig link, though. When I put this together, I figured that I needed about 35TB of space. Turns out, I could be perfectly happy with 20TB. So, let's talk about reconfiguring this beastie to get me the best speed. How do I find out what my bottleneck is?

Usage:
1) Datastore for 10-20 VMs.
2) Storage space for ISOs, documents, movies, etc. I've got everything on here, and I access it daily - mostly streaming video.

I've got a backup solution, so don't worry 'bout that. I just need speed and a little bit of uptime protection. ZFS on CentOS 7, in a VM with 2vCPUs (E3) and 8GB RAM allocated to it. LSI 2308 passed through.
 
You should be able to get 24x100MB/s from your hard drives. Maybe you should access them differently.
