Hello Mark,
The planned replacement is based on the newer NVMe-oF protocol and
SPDK. See this presentation for the purported performance benefits:
https://ci.spdk.io/download/2022-virtual-forum-prc/D2_4_Yue_A_Performance_Study_for_Ceph_NVMeoF_Gateway.pdf
The git repository is here: https://github.com/ceph/ceph-nvmeof.
However, this is not yet something recommended for a production-grade
setup. At the very least, wait until this subproject makes it into
Ceph documentation and becomes available as RPMs and DEBs.
For now, you can still use ceph-iscsi - assuming that you need it,
i.e. that raw RBD is not an option.
