[SOLVED] PVE on SATADOM

[kyriakoschar]

Hello starter here and i am thinking to install PVE on 2 dedicated SATADOMs (as mirroring boot drives), in order to save 2 sata slots from my mobo.

Supermicro's solutions are these below:
64GB with READ/WRITE = 520/95 MB/S
32GB with READ/WRITE = 280/50 MB/S
For both drives, supermicro gives 1DPWD endurance (and something UBER values) but i didn't find if there is a PLP feature. Does anyone knows if PLP applies to this drives?

Also, i would like to ask if such drives are ok for PVE , i mean by the perspective of speed (is it ok the 280/50?). My plan is to use them only as boot drives on an 24x7, ups powered home server. Other files like ISOs, tempates etc, will be stored probably on the 2 SSDs of VMs (which i will need some advices in another topic in the future).

Thank you!

Performance shouldn't be problem when even HDDs are totally fine. Its more about the durability of cheap flash because of the write amplification as PVE is doing tons of small writes (here ~10GB per disk per day). Especially when using ZFS for your mirror.

I have satadoms on supermicro and i hate it. I will rather buy extra sata card and normal ssds.

Even with 280/50 mb/s read/write speed?

Is the 1 DPWD sufficient enough for PVE?

Is there a wear on these drives over short time that it made you to regret installing them?



I am reconsidering for 2 ssds for pve + vms + lxcs

SATA domes are generally intended for read-intensive systems, not write-intensive systems. DWPD also only says that you can write 32 GB per day, but the value is limited by the warranty, so if you have 3 years, you have a TBW of about 35 TBW. Enterprise SSDs with 120 GB cost about the same and usually make 350 to 600 TBW.

ok. I turned my research and i am searching options for mixed use like intel S4620 now. Thank you all for your valuable info!

Totally agreed. Satadoms on supermicro are nightmare. Try to avoid it
