Displaying XIV Cache size

The XIV GUI is all about simplicity. Its about taking tasks which on other products are difficult or time consuming, and either eliminating them, or making them as simple as possible.
But for those who like to issue commands via a command line interface (a CLI), the XIV also has a very rich CLI called XCLI.
If your familiar with the XCLI your hopefully aware that list commands can produce much more detailed output if the -x option is used (-x requests XML output).
So here is something you can try out.
If your XIV is on 10.2.1 firmware you can use the module_list -x command to display how much server memory each XIV module has.
If your XIV has 2 TB disks, you should find that you have 16 GB of server memory per module.
This means a 15 module machine has a whopping 240 GB of server RAM.
To be clear, I am not referring to this as 'cache' because a small portion (around 2.5 GB) of the RAM in each module is used by the modules internal Linux operating system.
This means that a 15 module XIV with 2 TB drives and 16 GB of server memory per module, has over 200 GB of cache.
As former Australian Prime Minister Paul Keating once said: "its a beautiful set of numbers"
