I setup an i7 3770k system in 2012; ran it as my primary machine all the way until a couple years ago when I moved to a 5800x.
This is Ivy Bridge, not Sandy, but frankly apart from Intel cheeping out on the TIM by using paste instead of soldering it may as well be the same.. arguably worse since Sandy could generally be overclocked further.
That 3770k system got turned into a Proxmox server; pfsense, TrueNAS Core, few other misc low demand VMs.
Here's the rub: I recently swapped the 3770k for a 3770 because the k model does not support VT-d for some reason.. I had to use PCI-E passthrough in order to use TrueNAS reliably (NICs and an LSi HBA for the six SATA drives).
Really the biggest limitation for me is core count and ram, I'm maxed at 32 gigs and ZFS loves ram. There's other quibbles like Asus not issuing an updated bios to implement Microcode updates on my P8Z77-V, but the Linux kernel has mostly mitigated it in software to the point that the remaining vulnerabilities are the kind I'm not concerned with.
I'm hoping to build a replacement next year.
I would like to talk about how great my 3770k was for lasting so long but really it's just because for gaming there was little incentive for a long time.
- whalesalad 3y agoWhat a coincidence. I too have a proxmox server running on my 3770k with an LSI HBA flashed to IT mode, on the same motherboard. Fortunately it works with Proxmox and that is where I am running/managing ZFS. I never attempted to run TrueNAS w/ pass-thru so didn't encounter that VT-d issue.
- refracture 3y agoA coincidence indeed. It has been a solid platform all these years. Now the question is do you also have it housed in a green Corsair Vengeance C70? I presume since you're running an LSI HBA on the same board you also had to tape over the SMBus pins as well. I had debated just running all of the HBA (IT mode as well though I didn't mention it before) connected drives direct on Proxmox with ZFS to side step the VT-d issue but I had some other use cases necessitating PCI-E passthrough that I didn't have a workaround for. The non-k 3770 was cheap enough that I was willing to go for it.
- whalesalad 3y ago> tape over the SMBus pins as well totally unfamiliar with this
- refracture 3y agoI have a Dell H310. The SMBus signal stops my board from posting. http://yannickdekoeijer.blogspot.com/2012/04/modding-dell-perc-6-sas-raidcontroller.html?m=1 http://yannickdekoeijer.blogspot.com/2012/04/modding-dell-pe... I think it’s just a quirk of the Dell LSI HBAs.
- whalesalad 3y agoAhhh I have an IBM card :sunglasses:
- dizhn 3y agoZFS makes good use of RAM but it actually does not need as much of it as people have been parroting. If you need the RAM for other things you should definitely try reducing ZFS's allocation. (All of this is assuming you are not running dedup)
- kbuck 3y agoYou can install the microcode driver to have Linux provide the updated microcode, if you'd like. (Depending on your distro, it might already be doing it.) https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-guidance/secure-coding/loading-microcode-os.html https://www.intel.com/content/www/us/en/developer/articles/t...
- scns 3y agoWhat a fine piece of writing!
- refracture 3y agoI'm running Proxmox (Debain underneath really) which has a meltdown-spectre checker package available, I followed a debian guide I believe for implementing the microcode and the results are mostly in the green now. I haven't looked into it but as far as I know I don't think I need to worry about this for the VMs but I could be wrong.
