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.

GFS is well suited for DEVOPS type environments where organizations prefer to invest in servers and DAS (direct attached storage) versus purchasing storage solutions/appliances. GFS allows organizations to scale their storage capacity at a fraction of the price using DAS HDDs versus committing to purchase licenses and hardware from a dedicated storage manufacturer (e.g. NetApp, Dell/EMC, HP, etc.).

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.

Scales; bricks can be easily added to increase storage capacity
Performs; I/O is spread across multiple spindles (HDDs), thereby increasing read and write performance
Integrates well with RHEL/CentOS 7; if your organization is using RHEL 7, Gluster (GFS) integrates extremely well with that baseline, especially since it's come under the Red Hat portfolio of tools.

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.

Documentation; using readthedocs demonstrates that the Gluster project isn't always kept up-to-date as far as documentation is concerned. Many of the guides are for previous versions of the product and can be cumbersome to follow at times.
Self-healing; our use of GFS required the administrator to trigger an auto-heal operation manually whenever bricks were added/removed from the pool. This would be a great feature to incorporate using autonomous self-healing whenever a brick is added/removed from the pool.
Performance metrics are scarce; our team received feedback that online RDBMS transactions did not perform well on distributed file systems (such as GFS), however this could not be substantiated via any online research or white papers.

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.

Almost perfect, some hoops to jump through after major upgrade, but overall simple and effective. Our storage administrator really likes the integration with vmware as it makes his life easier. Also it was no trouble integrating it with our active directory credentials. The only issue we had was getting the plugin in VMWare going initially.

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.

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.

Gluster is a lot lower cost than the storage industry leaders. However, NetApp and Dell/EMC's product documentation is (IMHO) more mature and hardened against usage in operational scenarios and environments. Using Gluster avoids "vendor lock-in" from the perspective on now having to purchase dedicated hardware and licenses to run it. Albeit, should an organization choose to pay for support for Gluster, they would be paying licensing costs to Red Hat instead of NetApp, Dell, EMC, HP, or VMware. It could be assumed, however, that if an organization wanted to use Gluster, that they were already a Linux shop and potentially already paying Red Hat or Canonical (Debian) for product support, thereby the use of GFS would be a nominal cost adder from a maintenance/training perspective.
