Usable Storage Capacity

Question

Is there a way or formula I can use to determine usable storage capacity? I'd like to be able to better guesstimate the usable capacity of each drive pack, without having to enter in workload information if that is possible.

Think this was covered in more detail the ask the experts thread, but will repeat a summary here as that thread has gotten way long. This is also in the presales deck on the enablement center http://bit.ly/SellVxRail

With the current hybrid configs, and FTT=1 you can use ~48% of Raw.

So I would just combine the SSD and HDD raw size and calculate for FTT ?

Nope, just the HDD raw size. SSD's are used for caching and not persistent storage. VSAN takes 1% for formatting and overhead and there is some space reserved on the first appliance for the infrastructure VMs.
