What Is Best Intel E5-2600 v4 CPU For A New TrueNas Core Build?

[uberguru]

Trying to build a new storage server running TreNAS CORE using Dell R730xd with 24 + 2 2.5" SSD
It supports Intel E5-2600 v4
I am thinking buying just one E5-2699v4 but wanted to ask you guys what will be the best CPU to use for this build from the E5-2600v4 family

Seems a bit overkill for a storage server and not worth spending $500 on given the age. Why not an E5-2683 v4 for 1/5th the price? Don't forget that you will need 2 CPUs to access all the PCIe lanes, so be sure to check the block diagram to see what will and won't work with a single CPU.

I think the E5-2696 V3 is still the budget king as it is basically a 2699v3 oem tray and is only ~$120 on Ebay

Perhaps things have changed though, and there is something even better out there?

18 cores at 145 W != 22 cores at 145 W

Is the improved handling of VMs on V4 CPUs worth it/noticable???

I clearly said budget king! If you can find me a cheap 2699v4 and I'll buy it

Also, the v3's have a "bug" where you can run all cores at full speed using some bios mod's if your motherboard supports it, and in that mode it will beat a 2699v4 as the 2696v3 will be running at 3.8Ghz on all 18 cores if you want it to

Do you factor in power efficiency when calculating your cost?
Imagine deploying these in a Dell M1000e blade servers
lets say 64 of those, imagine which one will be more expensive after 1 year of power usage bills

Use case? Besides TrueNAS for storage, what else do you need to run? VMs? Expected workload...i.e. home or or business ? Other hardware...mechanical disks or SSD (it was unclear to me if its all SSD or not), and what speed on the network?

Honestly, at the low end of the TrueNAS spectrum: to be "just" a NAS for home, with mechanical disks and Gigabit networking, you just need enough CPU to keep ahead of the other components, so that they are the bottleneck and not the CPU. For Broadwell, pretty much any of them will do that. A 2620 v4 goes for around $35 on Ebay. Gives you lots more money for disks and other stuff.

At home, for my "NAS Only" TrueNAS setup with SSDs (because I had them, and they are silent in my home office) the Gigabit networking is the bottleneck, not the onboard Atom C3558 CPU.

Things scale up from there of course. If your system will be reading/writing most of the time from SSDs over 10G, running multiple OS and passing through lots of GPUs and other stuff, then obviously more is better!

18 cores at 145 W != 22 cores at 145 W

The all core Turbo hacks aside, if you're going to use this as a NAS, then its probably going to be running either at idle or in short bursts most of the time? By the time of Broadwell, the difference in power draw at idle between the different model CPUs was negligible, and the Chipset & onboard components drew more power than the CPU.

Is the improved handling of VMs on V4 CPUs worth it/noticable???

If the system is at idle most of the time, then my vote is probably not. But at the lower end of the spectrum, the v4 chips aren't selling for much more than v3 and they are probably going to be a year (or more) newer.
