InfoSight...
...is the reason we like using Nimble with our managed services customers. The supports teams don't worry much about the arrays themselves, they simply consume and occasionally troubleshoot.
But they are not "storage people", typically they are generalists who only care that 1) it's fast enough; 2) there's enough capacity; and 3) it has no single point of failure. The nice thing about InfoSight is that when they start running into issues, it's dead simple for our storage specialists to analyse the data and make informed decisions as to how to proceed.
That keeps our managed services support teams busy supporting customers and their apps, and our storage specialists busy doing storagey things.
