Yeah, that is my concern exactly. I know the 3PAR system handles snapshots well, but I'm not sure how well. These are datastores for virtual machines running in VMWare so I'm guessing the change rate is fairly high.
My other concern is using snapshots as backups, but I suppose as long as the data is replicated off site it is essentially the same thing as a backup.

Is your concern is the performance impact that 14 snapshots, living off your production volume 24x7 will have?
If you know what your change rate, or write to read ratio, then we could get an idea of how concerned you should be. In a high change rate (lots of writes) workload, you would want to validate the setup to ensure the storage is sized to handle the overhead.
