Hyperconverge with SCSI MULTIPATH 10Gb/s DELL ME4024

[synergy-it]

Hello everybody,

I woul'd like to design an Hyperconverged infrastructure with 3 proxmox linked by DELL Fibre Switch S4112F in one hand and one DELL SAN ME4024 in other hand

We have configure LVM on the the cluster's datastore.

We have problème, only HA is available but, we have to have a continus activité without downtime. Can you help us to configure proxmox ?


thx,

continus activité without downtime

If you mean that VMs must keep running and be up even if the host running them goes down, then you are out of luck as there is no equivalent of VMWare's Fault Tolerance feature.

On PVE, HA will start the VMs again on a remaining node of the cluster if the host running them dies or gets isolated from the corosync (network(s)) after aprox 2 minutes. That time can't be changed.

Hyperconverged infrastructure

Hi @synergy-it, in addition to what @VictorSTS already said, the infrastructure model you are creating is not hyper-converged.
The most common definition of hyper-converged is when CPU, Network, and Storage are converged into the same nodes.
PVE+Ceph (when running on compute nodes) is hyper-converged.
What you described is standard SAN-based architecture.

Good luck
