			== Cabling ==

			The cabling for the Western Digital Data24 is a little different from how we cable SAS JBOFs. Where with SAS JBOFs we crossover so that each server is connected to separate IO Modules (IOMs) with the Data24 we need to keep the server connections all to the same IOM. In this diagram we show server 1 connecting to IOM-A and server 2 connecting to IOM-B. Two connections is sufficient and you can even get away with a single cable connection per server. Three or four connections could be done but they won't yield more performance due to filesystem overhead so we recommend two cables per server, again, to the same IOM.

			This is most easily done through the WD Data24 web user interface. After logging in navigate to the section for the IO modules then click on the slider for 'Shared' mode access on all IO modules. This makes it so that all the NVMe devices are accessible from all ports.

			# chmod 755 wd-set-devres.sh
			# ./wd-set-devres.sh -p admin
			</pre>

			The default username and password are both 'admin' for the Data24.
