“Look Ma! Capacity.”

We are the nerdy type around here, and as such we love graphs – they are an easy visual aide to what can be mounds of data – so it pleases me to share with you the graphs from our recent ‘Mail Storage Maintenance‘:

Daily disk utilization for E-Mail storage.

Daily disk utilization for E-Mail storage.

You can see we were hovering around 85%; which for the NetApp Filers is the point at which the overhead of maintaining free and used space begins to impact performance. Fortunately for us, the storage requirements for Customer E-Mail grows linearly, so it’s easy to plan ahead and have a new shelf ready to install:

Yearly disk utilization for E-Mail storage.

As you can see, it was about this time last year when we added more capacity, and if the graphs hold true, we will be doing another upgrade in a year; of course at some point we will run into power and other physical constraints, at which point we may need to do an even bigger jump to newer Filers with higher capacity disks; for now though, we all sleep a little bit better knowing we have plenty of room to grow for the coming year.
