I've lurked for a while and read most of the stickies, I played with configuring freenas on a vm a year or so ago and I'm finally about to do a build. Just a few questions remain.
This is the build I'm considering hobbling together
Intel SR2612UR
one or two xeons (quad core)
at least 32 gb eec buffered
12x or 6x sata 7200 750 gb
My plan is to have two vdevs so I can incrementally upgrade the drives in one or the other withoutneeding to upgrade all the drives at once, or is beyondraid available now?
The drives are second hand... and kinda old but pretty much free, is RAID Z2 going to be enough to compensate for that move?
Immediate use is a 3tb shared network drive and os backup for ~30 desktop systems and two servers, near term I would like it to also serve drives for vm's residing on a separate host but if performance is an issue it will just back up the drives.
Is there a noticeable performance difference between SATA 1, 2, and 3? Platters only spin so fast anyhow, and system ram is acting as buffer anyhow is it not?
In a trade off between more ram and faster ram which buys more performance? Options are 1333 MHz, 800 Mhz or 667 MHz. (max 96 / 192gb; one / two cpu)
Is a six year old xeon quad core going to max the system out or should I plan on buying a second one.
I saw some sticky bemoaning link aggregation as being useless, I can see how this would be true for cases where only one user is being served but when you have multiple users with simultaneous demand wouldn't it provide substantial benefit? And yes my switch supports it already. On the other hand 10 gig has really started to come down in cost, especially when you get lucky on ebay I'd really like to swing something with it.
