Dear Exports,

I'm trying to find the RAW Capacity of our VNX.
I can see the Pools capacity via Storage Pools Summary - Storage - Storage Config - Storage Pools, but I want to see Totals together for RAW and Usage able (including all Pools and CIFs)

If it is even possible

Its, easy just count the number of disks and multiply by their capacity!

does this help? https://community.emc.com/docs/DOC-33116

From memory, Unisphere doesn't tell you the raw capacity as its not a terribly important number. You can derive it from the reporting tools that show you what drives you have and their capacity - then as Gerald notes, you multiply them
Out to get raw storage. Or of you're feeling lazy, divide your useable capacity by 2/3 as that's the average raw to useable ratio that I see on VMX arrays.

Doesnt Watch4net cost a bomb?

I was going to add the disks, but thought it would be able to tell me from the Unisphere GUI itself. How poor is that!...

So I guess there is no summary page that tells you the whole array on RAW and Usable (adding all the pools together)...
Any good free monitoring/reporting tools out there?

I'm curious as to why you care what the raw storage is? It's a largely  irrelevant number as you can't store anything there.

The pie chart on the home page shows you allocated, unallocated and available space - those *are* important numbers.

Solar Winds has some good monitoring tools that are worth taking a look at.

@duncan, that was my feeling, whatever the RAW capacity, its irrelevant. EMC probably don't make it easy to find out as that would show off how bad the utilisation is!

@jack, make sure you dont get caught in the 1000x1000, 1024x1024 trap when comparing numbers (approx 7% different)
