Hi,

thanks for your quick response.

The reason I'm asking about iSCSI is because I have been able to deploy and use it in earlier releases (the last one was probably Pacific), but I'm struggling with deploying NVMe-oF in a virtual lab cluster. I haven't had the time to really dig into it yet, so there's definitely a knowledge gap I need to close. Until I made some progress with NVMe-oF I thought maybe iSCSI could still be used. The use case is to grant access to an air-gapped Ceph cluster.

Thanks!
Eugen

Hey Eugen,

AFAIK the Ceph NVMe-oF Gateway superseded the iSCSI one: it's actively
maintained, more performant, scalable, secure and better integrated with
the Ceph management & observability framework.

I'm curious: what's the target platform/use case for iSCSI that NVMe/TCP
cannot fulfill?

Kind Regards,
Ernesto

Hi,

could someone clarify if using iscsi via cephadm is still supported or
not? According to [0] it's "in maintenance" since November 2022, so no
active development. But it's still documented in all active releases
and can be deployed in Squid or Tentacle (though I haven't checked if
it actually works).
Is it still supported to use iSCSI?

Thanks!
Eugen
