I'm using freenas on HP Microserver Gen8 in home for 2 yrs and oversatified about it.
and now I'm planning to build a bigger one for my department use(I worked at a small research institute in China ,and partly act as the IT expert for my dept of about 20 people.)
The use case is mainly as a samba file server for near-line storage,and hosting my department's tiny internal web site(just static HTML for announcements,and a web mail),and maybe temporarily(2-3 weeks per time,<5 times per year) host a few(<10) virtual machine's storage (the computing task is on another server with powerful CPU but w/o big storage)for testing purposes.
The planned config is
2U rack server w 12*3.5 SAS drive bay(HUAWEI RH2288) /Xeon E5-2609V4(8cores/1.7GHz) /32GB ECC RAM/Intel X520 dual 10Gbit NIC/12*3TB or 4TB NL SAS drive
3*16GB sandisk cruzer fit drive mirrored for boot env
my problem is:
1.Is the CPU over or under configured?I've chosen it for it's the 2nd cheap one in the server model's processor options.And there's an E5 1620 V4(4C*3.5GHz) at same price,high frequency/less cores and lower freq/more cores,which one is better for freenas?
2.I know the more the better, but is 32GB RAM enough?
3.If 64GB RAM recommended,Should I add a L2ARC/ZIL device?
Thx a lot in advance!
