Isilon/PowerScale protection sizing practice

Practice the sizing rules for Isilon/PowerScale by inputting the variables that would effect the striping and/or mirroring of files and see the result. This should help with one of the tough parts of the Isilon Admin, Advanced Admin class and their respective exams.

Note:PowerScale is the re-branding of Isilon in 2020 to standardise the naming of Dell products (see: Isilon & PowerScale documentation).
If you wish to sample real data for Isilon/PowerStore sizing (for evaluating a migration for example) see: Isilon/PowerScale capacity calculator.
