Yes - if stability is the only consideration so sticking with EMC is a very good idea, but it's not.
There are also other considerations, like money - EMC (and it's maintenance) is expansive and many times you need a lot of storage for an unimportant purpose. There's also the fact that there's a limitation on how many servers you can physically connect to the EMC.
So the right answer is, like always, somewhere in between, trying to meet all the needs with one solution is very ambitious, there should be a few solutions available - not a single one and not dozens of them. The important thing is that when you arrive to a point where you decide to use a new solution:
- You do it for a good reason.
- You "take care of it" - you need to test it, monitor it and have a standard for maintaining it, just like you have with any other solution.
Hopefully this atones for my sin...
