Recommended enterprise level SSDs for PM 8 on 1U server?

[mylesw]

I'm looking at custom building a 1U server designed for colocation, where it won't be serviced regularly. My goal is a low power consumption platform (ie. AMD EPYC or similar) with a 20TB+ storage system that removes most of the challenges of spinning HDD failure rates. I was thinking SSDs would be up to the task here, but would be interested in anyone's experiences to date on this.

My goal would be to have a PM 8 level server built with about 20 x VMs on it, mainly Rocky Linux VMs, but the possibility of a Windows server in there. I realize each VM would have its own filesystem choice, but was hoping to do everything I can to reduce SSD writes to get the greatest longevity out of this server. I'll install as much memory as needed to remove the burden on the SSDs.

Thoughts?

Thanks in advance for any input.

In general I can recommend Samsung. Either the PM883 (are cheaper than the PM893) as SATA or NVMe e.g. the PM983.

If you get 10-12 of these into a server and use them in ZFS, TBW should never be an issue either.

I run the PM/SM 863a and 883 in CEPH storage and have had no problems so far. The wear and tear is so minimal that I can probably still use it in 10 years.

State side the cost metrics (for the moment) seem to skew heavily NVMe over SSD for cost per TB. If your chassis supports NVMe I'd lean hard that direction. 4TB also seems to be the sweet spot when I was shopping the other month

Have used Samsungs/Solidigm without much fuss. Solidigm does have some tooling for keeping the FW current/troubleshooting on their offerings that is .deb friendly which is nice.
