Samsung SSD 970 EVO Plus 500GB PROXMOX RAID-5 (RAIDZ-1)

[ed9]

Good day to all,

I setuped RAID-5 configuration and did some disks performance/efficiency tests. Main idea is to check RAID-5 efficiency with this server configuration:

CPU: 48 Cores @ 2.8 GHz
RAM: RAM DDR4 256GB 2400
Disk: 4x NVME 500GB (Samsung SSD 970 EVO Plus 500GB)
Raid Level: Custom
NIC: 3Gbps Uplink

Everything was tested with fio tool, all tests are done, but there is no material with which to compare the results. Maybe somebody did same tests with Samsung SSD 970 EVO Plus 500GB and RAID-5 configuration or maybe know some useful articles?

Thanks in advance,


P.S. Parameters I'm interesting in: I/O, Read/Write, Random Read/Write; Read/Write at the same time, MB/s, latency.

Do you want to run guests on that raidz? If so, you might want to reconsider that and setup the pool in a RAID10 like setup with 2 mirror vdevs. We have a section in the docs explaining the details behind this: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_zfs_raid_considerations

Thank you for the reply! I want to run some virtual machines on raidz-1, so I'm interesting in disk pool efficiency and how much data can I put into it. I have already all result, but want to compare with something, with some other tests, what people maybe did as well with this type of SSDs and RAIDZ-1.
