Is an Intel Xeon E3-1245V3 CPU overkill for me?

Hi all,

As the title suggests, would this be a waste of money?

I'm going for a zfs system serving ~40 people from 6 x 2TB WD red drives set up in a RAID-Z2.

The NAS is going to be used primarily for file sharing and will also host a wiki - probably dokuwiki.

I'd rather put the money into more ECC RAM and get something like a Pentium G3450.

For that specific use it would be overkill, you would be better of with more RAM.
If the price difference is not too high try an i3 instead of the Pentium, this way you will get better LZ4 compression performance (which I definitely recommend you use, as it will INCREASE performance).
Also make sure to check if the CPU support ECC on Intel site.

Well, if you are using samba, it requires CPU resources and 40 people through a fast connection are enough to bring that G3450 to its knees...
But on 1GB your NIC will most likely be the bottleneck, and not the CPU
I will let others say their opinions, too, however...

P.S.: Keep in mind that E3-1245v3 has an integrated GPU (which you might not need and save some money from there - eg E3-1241v3 is faster and cheaper)
I suggest you post your hardware specs here so that we can see the whole picture...

it depends which workload the 40 people are producing.

40 people accessing the server constantly (i.e small files like in home directories) then go with the e3.
40 people storing large files and accessing them infrequently. and pentium cpu will be fine.

but like erico said. more ram with help both scenarios.

Thanks all for the replies,

The NAS is not going to be hammered by all 40ish people at once, it will get light use frequently.

This is what spec I'm looking at going for:

Mobo - Supermicro X10SLH-F 1150
CPU - Intel Core i3-4370
RAM - 32GB (4 x 8GB) Crucial Unbuffered ECC
Disks - 6 x 2TB WD Red 3.5" (RAIDZ2)

Will this spec be suitable for our needs?

Thanks

for light use that should be enough.

Looks fine from here....
There is only one thing you could consider:
A x10sll-f is cheaper than x10slh-f. If it covers your needs you could save a few bucks from there...
And if you feel like it, add a few more bucks to the ones you will save from the mobo and invest in a xeon cpu (after the fiasco with sandy/ivy bridge i3s, when intel suddenly decided that they do not support ECC, I would not trust an ECC oriented build with an i3)
Example of an alternative CPU would be an E3-1226v3
