oVirt is definitely more professional especially since its running on rhel nix vs proxmox that works on debilan; but as long as you keep it monitored, and handle stuff in respective amount of time there's nothing to worry.

non branded just lsi are best in my opinion - branded often have limitations in io queue depth or integrations for their management controllers like idrac, bmc etc. (or even hardware lock) from 9300-8i raid mode cards here are some options (battery is desired)...

for vga server board you would want something like this (vga to hdmi converted with power over usb ~ often servers want to have that usb power - often one of the usb ports is marked with wench, 'i', or lightbulb - its likely intel board also has one port like that - as supermicro also has it ~...

I'd say cheapest solution would be proxmox, else you can try oVirt but there's less usage - and cert expiring can nuke your setup.

As per photo you posted earlier each of backplanes you have there have 2 sas cables going out of them. You can get 2 sas/raid controllers and use mpio (Each backplane would have 1 cable going to raid controller 1 and 1 cable going to controller 2; same for the other.) So if one pcie card fails...

if you plan on doing docker HA and still use more than half your nodes - you need to go kubernetes if you want to be "free"; Else if you are ok loosing 2 nodes, you can use linux pacemaker or similar and just run mirrored nodes. (would need rhel *nix)

I guess purpose is to do it - and if a disk dies, you can still get your data. If they had os on it - one would go to recovery mode / installation fdisk and bring the dynamic disk online. (one may have to repair mbr/boot whatever) Typically there's software (like MegaRAID) with any raid...

you can use pretty much any lsi sas controller (there are break-out cables for sata/sas) I recommend something of 9300-8i or 9400-8i (if you plan on nvme's). https://www.amazon.com/Cable-Matters-Internal-SFF-8643-Breakout/dp/B01BW1U2L2 (if you plan connecting that 2nd backplane with 9300/9400...

The 2nd disk is connected over sata/300 cable/controller | while the other is connected at rated sata/600 mode. (or the other way around 2nd disk being 3Gbps version, and 1st one is 6Gbps version) sata/300 = sata2 3Gbps sata/600 = sata3 6Gbps

Just a note, if one of your dynamic disks in mirror goes down - your whole dynamic mirror will set as offline - thats why windows doesn't allow it - as you won't be able to start your system if 1st disk dies/gets removed. Just get lsi 9400-8i tri-mode raid controller (they aren't that...

for fp64 it might be worth to look at amd with zluda; there's been plenty of development on amd/windows side to run on directML (MI100, 210 might see a new life with those) (just last night i managed to run stable diff on 7900xtx on windows10 ~ i don't have good comparison at this time with nv...

Those are not SMR, but CMR and you can format them to 4096. This is a ok price for 8tb sas hdd. 8TB ones with 4kn tend to cost around 35-50 usd depending on their smart state, i suspect smart state isn't great - thats why the price is 35ish. (i have like 8 on stock myself @ Home, they are worth...

The 22G variant or RTX 5-8k are definitely better deal in terms of vram; the int8 or tensor performance is small price to pay for capacity. In terms of performance in int8 in nv cards its almost always 4xfp32 since volta if i recall correctly - tho it doesn't scale that well in reality, Titan V...

you'd need to link to a specific drive; SMR typically = garbage for large storage, doesn't play well with zfs.

is this wd branded? or ibm/oracle/cisco?

I also do remember some disks not being recognized in certain backplanes - backplanes also having limits.

sorry changed; open viewer access granted to all.

Just FYI in case someone looking Titan V has recently gone cheaps Can be bought at around 400-500 usd on ebay. For those interested here's of cards i had for my own research (non-sxm2 - compute fp16 oriented)...

Whats the make&model of the disk; Have you formatted this model before to 4096 with sg_format?

some older controllers can't see disks over certain size.
