Question about maintenance

[killmasta93]

Hi
So currently i was running proxmox on version 6.4 with various VMs and was working fine,
the server was a dell r720 with 192 gigs of ram 2 CPU and 8 SSD, i then bought another server same config, but i put proxmox 7 and passed all the VMs to the new server
and what i saw is that the VMs were much faster,
My question is, do i need to do maintenance on the servers when running SSD? or is it just because on version 7 of proxmox is much faster?

Thank you

bump?

same storage config ?
same ssd ?

 

[killmasta93]

yeah same config same everything my only guess was the version and because its recently formated.
but i was wondering if there is a special maintenance one has to do on proxmox?

I don't know any maintenance on pve.
What SSDs do you use ?
Do you use ZFS ?
+ On these old cpu, I set mitigations=off as kernel option.

correct using ZFS using disks bx crucial 1tb

Thats a terrible SSD for use with ZFS (and terrible in general because except for the old 120GB versions it uses QLC NAND).

 

[killmasta93]

its working awesome on the new servers, or alteast its better then SAS 10k disks, but would would you recommend?

An Enterprise SSD with power-loss protection so sync writes won't be terrible slow and killing the SSD very fast. Or at least a Consumer SSD with DRAM cache and TLC NAND (not recommended...but still way better than QLC).

Crucial BX is the worst for ZFS. I don't know how do you get normal performance with this config.
They are burnt. How many months (years?!) they run ?
Here I trash many of these (mainly 120GB/240GB so, the no many freespace doesn't help) after 4-5 years , only used on baremetal Windows.
They become slow, and they writes sequentially 0 (the easy top speed bench) at 10MB/S instead of their 300 MB/S out of the box when they're empty.

Killed two of the BX 120GB versions (the ones that still use TLC NAND) in under a year when used as a TrueNAS system disks ZFS mirror.

currently have it 2 years working fine

Consumer SSD do you recommend Samsung?
