To join an Xsan 5 SAN, computers must meet the following minimum requirements.
If you’re using macOS Server 5.2 on OS X 10.11.6, you have Xsan 4.1.

Xsan 5 clients and controllers must have macOS 10.14 and have the ability to connect to either a Fibre Channel fabric or a wired 1GB network.

Client computers must have at least 4 GB of RAM.
Computers used as metadata controllers must have at least 8 GB of RAM for macOS Server and one SAN volume, plus 2 GB of RAM for each additional SAN volume hosted by the controller.
For example, a controller should have 8 GB of RAM to host one volume, or 10 GB for two volumes.
