Hi guys
Confused which optane is supposed to be good for VM storage for high drive writes. Im using blueiris cctv and eanr high performance with high drive rights. I have 3 x 2280 slots on my motherboard.
Many say these drives are super cheap but I can’t find them or im confused as to what model I need.
Can anyone confirm?
Thanks
Cheap optane drives in M.2 format large enough for your purposes I don’t think exist.
Optane m.2 (M10 drives) came in 16GB, 32GB up to 118GB
The H10/H20 drives have an optane cache but normal TLC NAND made up the bulk of the drive but I suspect would mostly act like normal drives in your use case (streaming writes)
How much space are you looking for, how many cameras?
In PCIe format they get bigger - but thats not what you want.
I have 14 cameras. I can see there are 1TB Optane M2 drives - its CCTV so im not bothered if they fail. Perhaps 2 x 1TB in striped format and I can off load the recordings to my 6 x 2TB WD spinning disk for archive purposes.
I was thinking two of these ? Or maybe 4 as my asus z890 prime has 4 x M2 slots.
Perhaps the 32GB flash ( or 64gb when stripped) could be used as L2ARC?
My system has 64GB memory and the intel Ultra 7 CPU.
It seems not worth it compared to a high durability drive like the WD black nvme 1tb.
The optane pcie cards are too big and not using m2 and too costly. Doesnt appear to make sense using the h20 compared to new nvme
There are no 1TB optane drives. Not M2, and not proper ones. If you are referring to H10/H20 drives then they are QLC NAND with a 3DXpoint cache. In the example you give its description is misleading. Its a 1TB QLC Drive with 32MB of Optane Cache on it (the description says the otherway around). The drive will work normally as a 1TB drive (I believe) however there appears to be a caveat.
The dual controller setup on the single M.2 module makes compatibility a bit tricky, though. To use this device, the motherboard has to support bifurcation. That feature allows the PCIe 3.0 x4 device to operate on two separate PCIe 3.0 x2 links. The acceleration also only works on systems with Intel 300-Series chipsets, and only if the device is connected to the platform controller hub (PCH). The drive also requires the RST Driver 17.2 (or greater).
So if you want a normal 1TB drive, that works at PCIe 3.0x2 then thats all it will be. You need motherboard support, driver support & bifurcation to use the optane cache.
Its endurance is not leading edge either. Unlike a real optane drive which has enourmous endurance.
Great info thanks. Then the search for nvme low cost drives with good durability continues. The pure optane drives are expensive still (non h10/h20) and are pcie which consumes alot of space.
Yup.
Even the M10 drives don’t have stunningly high endurance, or speed - you need the PCIe / U.2 drives for a proper optane drive. And those ain’t cheap
Something else - why use NVMe at all for this purpose?
Are you very space-constrained?
I’m pretty sure you’d come much cheaper here with some HDDs.
Yes the 4u case doesn’t have much space left. Im using thr 4 x 2.5 bays for drives that serve as mirrors for other VMs (plex , openhab, promox etc)
The 10 bays in the case provide SAS/SATA drives for truenas storage - these bays are served by a LSI 9305-16.
I really want to run blueiris cctv on fast disk but anything over pcie3 is really overkill for 14 cameras.
See if I can fit another 2 x 2.5 Intel enterprise SSDs. There isnt anything price comparable.
I’m stil missing something. Why not use the disks in the 10 bays for cctv? Does that need so much performance?
Could you provide a full hardware overview?
Asus Z790 Prime MB
64GB DDR5
Intel Core Ultra 7 285K CPU
Silverstone RM41-506 Case & Corsair 850watt psu
2 x Silverstone SST-305E Drive Bays (accepts 5 x SAS/SATA)
LSI 9305 16 HBA Adapter - has 6 x 2TB WD RED & 2 x 1.96TB Dell Enterprise SAS SSDs
I pass the entire HBA to TrueNas and run the following from the internal sata ports off the motherboard:
I think it might be easiest if I just run BlueIris CCTV as a VM inside TrueNas rather than Proxmox.
Would solve the problem - I can just mirror the 2 x 1.96TB SAS SSDs
That would leave some VMs in Proxmox and BlueIris as a VM in TrueNas
Hope that provides some context?
I now definitely understand your configuration better. Just to be sure, you mean 2TB WD RED SSDs right?
If you are already running proxmox I’d not want to run the VM nested on TrueNAS.
Why not run a seperate VM for blueiris cctv and use some share from TrueNAS (I don’t know the software.. NFS/SMB/iSCSI…) as storage for it?
You’d have to set the startup order of course.
Yes but blueiris needs to run on SSD for best performance. And this is what I lack- hence looking at reliable nvme because my motherboard has 4 slots for them.
Long term cctv video retention will absolutely reside on the the spinning disk array presented to blueiris via SMB/NFS as you said.
In that case, some WD Red SN700 M.2 SSDs?
Strictly speaking that’s true: There are 750 GB and 800 GB drives (HHHL or U.2), and then 1.5 TB, 1.6 TB and even 3.2 TB drives.
M.2 stops at 373 GB, in 22110 size.
But why throw high end drives for CCTV footage? Pearls for pigs and all that…
Note that Intel has discontinued driver support for H10/H20, which ultimately are old QLC drives and never were suitable for any kind of demanding application.
I dont want to throw high end drives at it. Just with the caneras writing 24/7 id imagine it would just burn the consumer nvme drives.
Looks like the WD red sn700 though fixes that! Didn’t know this drive existed. That would solve it.
