New page

= NVMe-oF Target Configuration =

QuantaStor can present Storage Volumes over NVMe over Fabrics (NVMe-oF) in addition to iSCSI, Fibre Channel, and CephRBD. NVMe-oF carries the NVMe command set across the network fabric instead of translating through SCSI, giving lower command overhead and deeper queueing than iSCSI on the same media. It is available on both scale-up (ZFS) and scale-out (Ceph) pools.

== Transports ==

* '''NVMe/TCP''' — works over any standard Ethernet fabric, no special NIC required.
* '''NVMe/RDMA (RoCE v2)''' — requires RoCE-capable NICs on both target and initiator, and a lossless fabric with Priority Flow Control (PFC) and Explicit Congestion Notification (ECN) enabled end to end. Recommended for latency-sensitive block workloads.

== How targets are modeled ==

Each Storage Volume exposed over NVMe-oF gets its own NVMe subsystem, identified by an NQN, the same way it gets an IQN when exposed over iSCSI. Host access is controlled per volume by initiator NQN, directly analogous to iSCSI initiator ACLs, see [[Storage Volumes#Managing Host Initiators|Managing Host Initiators]].

== Enabling NVMe-oF on a target port ==

NVMe-oF is enabled per network port rather than configured as a separate target type.

Via the Web UI: '''Storage Management''' > select the storage system > '''Network Ports''' tab > select the port > '''Modify'''. Check "NVMeoF Portal" (the Network Ports list shows this same setting as an "NVMeoF TCP" column, same flag, inconsistent label).

[[File:nvmeof-ports-list.png|thumb|400px|Network Ports list, showing the iSCSI and NVMeoF TCP columns per port]]



The dialog also has a "Lossless Networking" checkbox, this is the RDMA/RoCE toggle, it's only selectable when the NIC actually supports it, greyed out otherwise.

[[File:nvmeof-modify-dialog.png|thumb|400px|Modify Network Port dialog, showing the NVMeoF Portal and Lossless Networking checkboxes]]



Via CLI:
qs target-port-modify --port <port> --nvmeof-enable true

The same option is available when creating a floating service VIF or an HA failover interface, so an NVMe-oF-enabled target can be made highly available the same way an iSCSI target is.

== Connecting an initiator ==

Standard NVMe-oF host tooling applies (Linux nvme-cli, VMware NVMe-oF adapter, etc.). Discover and connect using the target's NQN and portal address as you would for any NVMe-oF target; QuantaStor does not require a proprietary initiator.

* [[Network Shares]]

== Changes needed on the Storage Volumes page ==

See the separate "Storage Volumes Full Page Corrected" doc for the exact, ready-to-paste page text with both edits already applied, and "Storage Volumes Wiki Edits" for the explanation of what changed and why. Not repeated here to avoid two slightly different copies of the same instructions drifting apart. Short version: the existing "Managing Host Initiators" section gets one word turned into a link, and a new "NVMe-oF Access" subsection (three equals signs, matching its siblings) gets inserted right after it, before "Managing Host Initiator Groups".
