Cluster & HA Archetecture

[Sikjairi]

Hello Everybody

I would like to rebuild a new architecture of proxmox cluster with HA To ensure the High Availability of my VM Servers , Could someone give me the best practices and the best storage type with my following Hardware ? Thank you .

1-Dell PowerEdge R640:
-cpu : 32* Intel(R) Xeon(R) Silver 4110 CPU @ 2.10GHz (2 sockets)
-Ram : 128 go
-Storage : 2*446go SSD (RAID1 446go)_ 5*2235go SAS(RAID5 8940go)
-Network :4* Intel(R) GbE 4P I350-t rNDC
2-Dell PowerEdge R640:
-cpu : 16* Intel(R) Xeon(R) Silver 4110 CPU @ 2.10GHz (1 sockets)
-Ram : 64 go
-Storage : 2*446go SSD (RAID1 446go)_ 5*1117go SAS(RAID5 8940go)
-Network :4* Intel(R) GbE 4P I350-t rNDC
3-HP proliant Gen10:
Cpu : 8 x Intel(R) Xeon(R) Bronze 3106 CPU @ 1.70GHz (1 Socket)
Ram : 16 go
Storage : 2*300 SSD
Network : 4 port
4-Dell EMC NX3240 (Storage server NAS)
Cpu : 8 x Intel(R) Xeon(R) Bronze 3106 CPU @ 1.70GHz (1 Socket)
Ram : 16 go
Storage : 600go ssd 1600 go SAS
Network : 4 port

5-Switch HPE Aruba Poe 24 port

6-Switch HPE office connect Poe 24 port

NB: possible to change storage disk to another server

Could someone give me the best practices and the best storage type with my following Hardware ?

Ceph. I'd see that each node has a smaller SSD/NVME for the PVE installation and spread the reamaining disks and add ceph to all nodes and use those disks as Ceph OSD. Scalable, fault tollerant and reliable.

You can also add more OSDs to one node any time. The OSDs don't have to be spread evenly between the nodes, but it's not bad to do.

Hi t.lamprecht
As i am not expert in Proxmox , Could you please give me an example depend my Hard disks, how can i split the disks for 3 pve nodes ? if i use all storage i have for " Ceph osd " is that good ? Thank you a lot of .
