Nimble Storage was acquired by HPE in 2017. The enterprise flash array product line now goes by the name HPE Nimble Storage.

As far as performance, they are all very similar now regarding IOPS but Nimble is a nice and easy product. Only thing it lacks is the multiprotocol. Upgrades are easy to deploy.
The Main reason for choosing HPE Nimble Hybrid storage is the Cost. However, even though its not ALL Flash Storage it was still providing the high performance, Latency less than 2 ms, good compression and de-duplication, zeop downtime on software upgrade, good reporting through …
Dell EMC Unity is an easy system and very flexible component and very easy to navigate while providing effective services and management of multiple project information management and the data pulling from the supported third-party platform is easy and quick. Excellent reporting features and easy to use and the analytics tools are amazing.
HPE Nimble Hybrid storage is very cost effective that can provide the same Latency, I/O and Bandwidth compared with any other All FLASH storage which is 3 times expensive than this. From a feature comparison standpoint of view, there isn't much difference between Hybrid Vs ALL Flash. HPE Nimble Storage uses ALL Flash disk at the front end to process the data thus by reducing the cost by using a regular SAS disk at the back end. Its the software and the algorithm that HPE Nimble StorageE uses to achieve this. having said that, the overall data reduction, de-duplication and compression is above the mark as what the sales team promised initially. Overall, the storage is performing well without any challenges.
HP Nimble is basically an all in one SAN with SSD cache or in some cases fully SSD based however the thing it does the best is its front end GUI and user management capability making it easy for anyone to ramp up on managing it quickly.
The Nimble SAN is also very easily managed when it comes to hardware management. Outside of some major internal parts such as the mainboard, almost everything in the system is duplicated so single failures never bring the system down. Power supplies and drives are easily swapped out.
Nimble has incredibly capable and easily accessible support that is available 24/7.
The price point on Nimble, though higher than piecing together a home made SAN out of spare Windows Servers, is perfect even for some SMB's.
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.
Nimble is doing its job well and any issues that do come up cause the Nimble support team to alert us before we would potentially see an impact to our production environment. I do wish we could expand into the unused space in the CS210 shelf which is limited by what I assume is a marketing/sales strategy, but we will likely add shelves moving forward.
Not only support for Unity, but for any Dell product, whether for companies or for the end consumer. Support is agile, helpful, and always focused on solving the problem. To date, there has been no problem that Dell's support has failed to resolve and help us with.
Any time I have had to contact support, they have always been quick to respond, and very efficient in resolving any issues. When an action has been required on our side for a fix, they have been very helpful in explaining step by step what was required, and when replacement parts have been needed, we've had them within 24 hours.
I was instructed to buy these arrays, but I was not given the opportunity to evaluate other arrays. We evaluated other products in the market that competed with Unity and found that the younger array built from scratch had far better features, software, and ease of use. The Unity system has a unique way of storing the data when compared with other systems.
We used a Dell EqualLogic PS Series storage array for many years and it worked well. A big issue was that upgrading firmware required system downtime and during one upgrade I was unable to bring the systems back up afterwards. I spent several days on the phone over a holiday weekend with Dell and VMware support in order to get my systems back up and running. It made me very nervous about doing firmware upgrades after that.
