• Nimble provides top notch predictive flash caching that "just works". We typically see 95% + cache hits daily.
• World class support... You typically don't' call Nimble support when there are problems, they call you.
• The Nimble hybrid array is a cost effective solution with no compromises.
• Infosight, the cloud management dashboard, is easy to use and provides quick access to useful information.
• Our Nimble has had 100% uptime, 4 years and counting.

• Alerting: receiving an alert when an issue occurs. That is good to know. However, if the alert is cleared, or somehow no longer in alarm, no email is received. At times I will receive the email alert on weekends, not knowing if the issue is resolved or not until Monday when I can access the unit. I have learned in most instances, the alert is a false alarm, which could be a problem.
• The alerting itself is sometimes not clear. For example, it tells me the link is down, we reset the connection, the link is still down, a tech was dispatched, he troubleshot, and finally the alarm cleared. This incident took almost a week. It went back into alarm after he left, then suddenly it cleared on its own.

• I'd like the GUI to include more information for some of the features such as replication data totals each night. You have to go to the command line for this.
• It would be nice to have a feature built into the GUI that would show you the command line equivalent to get the same results you are seeing in the GUI.
• Although the intial setup was easy, they could always improve on that portion. During my setup, I did have to do a lot of back and forth with research on their site as to what each setting was that I was setting up. They could have provided some sort of description for each field within the setup that would have made it easier to know what they were having us set up.

• ROI on VxBlock is not so good since RCM updates cost a lot.
• ROI on Unity by itself is good, however.

• People walked by my office for the first time ever asking what did we do to the servers because they are much faster. I have never experienced that before when putting in a new piece of equipment.
• It has paid for itself in space savings of not having to increase the size of the array.
• Speed and performance and data migration times are all parts of my ROI. Its been a great ride so far.
