Proxmox VE 7.4 - DAS Connectivity

[Daniel_Marambio]

Hi!

I have a question about the connection and compatibility that proxmox can give me when connecting direct 4 Lenovo Servers to a Storage via 16GB fiber channel. (DAS Connectivity). *Without SAN Switch*

The storage has 2 controllers, each one with 4 fiber ports, which allows us to connect a maximum of 4 servers.

Is this possible?

Proxmox is based on Debian. Debian is a variation of Linux OS.
If your DAS supports direct host connectivity and it supports Linux, then there should be a guide/document on connecting Linux/Debian to DAS.
In general, there is no reason why it shouldnt work. But there are DAS systems out there that dont support direct host connectivity.
Check with your storage vendor support.

while this is unlikely, you will need to make sure your HBA is supported in debian 11; this is not nearly a foregone conclusion as it appears. check your make/model/firmware rev/available linux drivers errata.

Once your hba is working, you may need to do some configuration on the storage side. your targets will probably be set to auto and that SHOULD work, but if it doesnt you might want to set them to PTP (point to point) manually (and the HBA too.)

lastly, probably need to do lun mapping on the storage side to allow your HBA WWN.
