You can generate and print a PDF of this page, and then use the following worksheet to record NVMe over RoCE storage configuration information. You need this information to perform provisioning tasks.
Direct connect topology
In a direct connect topology, one or more hosts are directly connected to the subsystem. In the SANtricity OS 11.50 release, we support a single connection from each host to a subsystem controller, as shown below. In this configuration, one HCA (host channel adapter) port from each host should be on the same subnet as the E-Series controller port it is connected to, but on a different subnet from the other HCA port.
An example configuration that satisfies the requirements consists of four network subnets as follows:
-
Subnet 1: Host 1 HCA Port 1 and Controller 1 Host port 1
-
Subnet 2: Host 1 HCA Port 2 and Controller 2 Host port 1
-
Subnet 3: Host 2 HCA Port 1 and Controller 1 Host port 2
-
Subnet 4: Host 2 HCA Port 2 and Controller 2 Host port 2
Switch connect topology
In a fabric topology, one or more switches are used. Refer to NetApp Interoperability Matrix Tool for a list of supported switches.
Host identifiers
Locate and document the initiator NQN from each host.
| Host port connections | Software initiator NQN |
|---|---|
Host (initiator) 1 |
|
Host (initiator) 2 |
|
Target NQN
Document the target NQN for the storage array.
| Array name | Target NQN |
|---|---|
Array controller (target) |
Target NQNs
Document the NQNs to be used by the array ports.
| Array controller (target) port connections | NQN |
|---|---|
Controller A, port 1 |
|
Controller B, port 1 |
|
Controller A, port 2 |
|
Controller B, port 2 |
