Which SAN software will run atop RHEL?

[The Gecko]

I am on a hunt for any SAN software that can be installed atop RHEL/Almalinux/Rocky, kind of like you can install Proxmox on top of a plain install of Debian if you really want to go that way. My reasoning for this is because I want to perform performance tests with a Chelsio NIC and they only offer drivers for RHEL and Suse. If they offered Debian drivers, I'd be using TrueNAS Scale (Debian-based) as my SAN of choice.

What can you recommend?

This is kinda in my wheelhouse since I (recently) spent a fair bit of time deciding on my storage setup, moving forward (from an HA setup of Starwind NAS/SAN).

So...bottomline, in the RHEL world, there's pretty much nothing. With a caveat. If you're ok with the CLI, RHEL (and its derivatives) is rock solid and can be made to work as a SAN/NAS just fine. Yes, there's Cockpit...which kinda is similar to the Truenas GUI, but not quite. It can work, if your expectations are low-ish.

p.s. Proxmox is not really SAN software. Actually, it's not, period.

Edit: So, what did I finally go with? Truenas. I'm not thrilled about it, it does have some rough edges, but it's acceptable for now.

Edit2: That said, all my compute nodes run Almalinux 10.1, with SAN boot (iscsi) and NFS over RDMA and NVME-oF over RDMA for data from Truenas.

What will you boot via SAN. VMs? or Physical machines? You should really describe what you intend to do and or at least make a simple outline of your desired storage architecture.
Pretty sure that you can use iSCSI or NVME-oF on RHEL-clones. Another old and kinda forgotten is AoE.
I dabbled around with NBD but it was long time ago...

You can try napp-it cs, a copy and run multi-os, multi server ZFS storage web-gui that runs on Free-BSD, Illumos, Linux, OSX and Windows (Storage Spaces and OpenZFS). For the host backend in a multi server setup you only need Perl. Setup on any Linux similar to Proxmox, https://napp-it.org/doc/downloads/proxmox-aio.pdf

RHEL 10 has targetcli that can be used to set up iSCSI LUNs and export them. It also has iscsi-initiator-utils for connecting to remote iSCSI devices. You can also install nfsutils and/or samba but don't expect to use the RHEL server as a domain controller.

There are chelsio drivers included in the debian kernel already so unless the Chelsio ones provide some otherwise different functionality, it might just work ootb.
