Hello the community,
Are there charts on the message processing capacities per PMG node ?
i have to design some PMG for 1 million mails received+sent per day with a size of 50ko : how many nodes should I deploy (on recent materials) ?
Thanks for your answers.
The last weeks I did 172 benchmarks to find out why my write amplification is so horrible and to see what storage setup might work better.
In this thread I will try to summerize all the tests and explain what I learned so far.
Will post link when finished.
thanks for the release of Proxmox Backup Server!
PBS looks very promising in regards to what our company needs:
Incremental backups of our VMs, e.g. every 15 minutes
Flexible retention cycle, e.g. keep last 8, keep 22 hours, ...
One pushing PVE client, several backup servers pull...
we are currently in the process of replacing our VMware ESXi NFS Netapp setup with a ProxMox Ceph configuration.
We purchased 8 nodes with the following configuration:
- ThomasKrenn 1HE AMD Single-CPU RA1112
- AMD EPYC 7742 (2,25 GHz, 64-Core, 256 MB)
- 512 GB RAM
- 2x 240GB SATA...
Just ran these the other week, thought I'd share. I'll try to do some more proper ones on Linux, but before that happens here's some CrystalDiskMark ones on Windows 2019 (virtio-scsi).
The underlying storage is a single Samsung 850 PRO SSD.
I was pleasantly surprised by the QCOW2 performance...
