But will it blend?

Hello everyone,
This is such an awesome resource for lurkers like me who always sit around and read the posts, but always felt strange when asking a question.
So, I'm spec'ing out a new FreeNAS build, as my current one has it's case full and I'm growing my data requirements.

Chassis: Rosewill RSV-L4500
CPU: Intel Xeon E5-2620 V4
Motherboard: Supermicro MBD-X10SRL-F
RAID Controller: HighPoint RocketRAID 840A
Drives: Seagate IronWolf ST10000VN0004 10TB (x13)
SAMSUNG 850 PRO 2.5" 1TB (x2)
RAM: Kingston 64GB (4 x 16GB)

My original plan was to go with a RaidZ3 on the 13x 10TB drives, and going to mirror the 1TB SSDs so I can use them for small Virtual Machines.

I'm open to suggestions/criticism.
Thanks again, so much.

Blend? no.

- read the recommended hardware (see my sig for a bunch of good reads)
- avoid that controller.
- consider getting a 1620 or 1650 CPU. Higher core frequency > count in the typical FreeNAS use.

Will 64GB be enough for 100-130TB of storage?

Probably.

Normal recommendation is 1GB per TB, thus 128GB. I'm not sure if that actually applies at this scale.

And if you wanted 128GB to start with then you should consider 32GB Dimms so you don't use all your slots immediately.

Do you intend to use iscsi? VMs?

Cpu is not a good choice and rocket raid is even worse. But your memory choice is good.

Yes. Rather than using a RocketRAID, you should use an LSI HBA, and if you're going to get an LSI-HBA then you should just get the X10SRH-CF

http://www.supermicro.com/products/motherboard/Xeon/C600/X10SRH-CF.cfm

Which has 8 SAS3 ports off a LSI 3008 chipset and 10 SATA3 ports off the PCH, ie, it supports a total of 18 drives before you have to use a SAS expander.

I'd recommend the E5-1620v4 or the E5-1650v4 over the E5-2620v4
https://www.servethehome.com/intel-xeon-e5-1600-v4-workstation-processor-family-launched/

The 1620 is 4/8 cores/threads up to 3.8ghz and the the 1650 is 6/12 cores up to 4Ghz. The core*gigahertz of the 1650 is higher than the 2620, even though it has less cores.

As Samba is single-threaded per connected user, it can be more important to have a high clockspeed vs more cores.

I'm just starting with freenas and FreeBSD so I can't answer this question but I do see that the OP is planning to use small virtual machines.
Doesn't that mean that more cores could actually be highly beneficial for him?

I might be misunderstanding this. I'm not sure if he want's to run vms on the box or just store the virtual machine images on the box....
