VMware to Proxmox migration

[misterju]

Hello,
I would like to migrate my VMWARE infrastructure from 3 ESXs to proxmox. My servers are connected to a DELL SCv3020 SAS storage array via 12Gb 9300-8e SAS HBA cards.
Are there drivers available for Proxmox and if so where can I find them?
At the same time, are there any people who have already done this migration?
Thank you very much.

Should just work since the 9300 uses the LSI 3008 chipset which works with mpt2sas driver.

I use the Dell HBA330 in production which has the same chipset and runs without issues.

Thank you for your reply. Can you tell me how you set up the storage in Proxmox?

Took a look at the SCv3020 manual and it seems this storage unit supports direct connection to SAS.

Proxmox should be able to see each individual drive.

I use ZFS in production on standalone servers for its data/metadata error checking, compression, and snapshots. For max IOPS, I use ZFS RAID-10. For backup servers, I use ZFS RAID-6 (RAIDZ2). An intermediate option between RAID-10 and RAID-6 is RAID-50 (RAID-5 striped).

For clustered servers, I use Ceph.

Each server, irregardless of storage technology, boot off small drives using ZFS RAID-1. Rest of disks used for VMs/data.

No issues besides the typical drive dying and needing replacing.

I prefer ZFS myself but OP should be aware of , that ZFS formated storage can't be used as shared storage.
Would it work to setup one dedicated storage per node on the SAS?

Presumably you've already configured LUNs on your storage. Your PVE hosts will automatically see the disks. follow the instructions here: https://pve.proxmox.com/wiki/Storage#_storage_configuration to set up lvm-thick pools on them.

(lvm-thick is your only option.)

Hello,

Thank you very much for your answers.
On my DELL storage bay it is a volume that is attached to the 3 servers of the VMware cluster.
My idea is to remove a server from the cluster, install Proxmox on it and attach a new volume from the bay to it.
The unknown in my equation was the detection by Proxmox of the SAS connection.
I am now a little reassured and I will soon get started.
Thanks again, I will leave the post open in case someone has already performed this type of migration.

Have a nice day
