We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"We have been able to consolidate storage into Pavilion. Pavilions are our only SANs because it is a bring your own disk solution. When new drives come out, we are able to take out half of the drives in the system, put in new drives, move our VMs over to the new drives, take the other drives out, and populate those with new drives. Then, we are suddenly twice as dense as we were before. NVMe flash is only going to get denser and cheaper so we can make use of that every couple of years by just throwing newer disks into it at a fraction of the cost of a new SAN.""The high performance is very valuable, as well as the enterprise reliability features.""There's lots of flexibility in how we use the resources while also maintaining a small footprint."

"For access from virtual machines, iSCSI, and NFS, it is very good. It helps increase performance.""The way you're able to manage all your PowerStores as one solution is very good for us. PowerStore enables you to federate or cluster multiple appliances with automated load balancing. In terms of management, it's helpful that we can do it from a single interface where we're able to manage multiple PowerStores. When you have multiple PowerStores it works intelligently by running the workloads based on the needs of the infrastructure.""Dell EMC PowerStore is scalable.""You can add compute and capacity independently. We have sized the solution based on our current needs, but in the future we can choose to increase capacity if we grow our activity in the market. And if we have more business in our monetary system, we can increase compute. The ability to choose what we increase is a good feature.""Overall, we're quite happy with the product because we can move the data that is stored on more than 10 of our current storage devices to a single PowerStore.""PowerStore is easy to use. All the drives use soft encryption. To upgrade it, you download the app, and it runs by itself. It's very easy to deploy, share, and create volumes.""The administration tools take advantage of machine learning and make recommendations to the admins, and that makes the administration easier.""Gives us flexibility, performance, and ease of use. It also has some very good compression capabilities. We were looking for a solution that was easy to install in our VMware environment, that was flexible. PowerStore X is a type of a VMware cluster that you install inside your environment. If you have a VMware environment, like we have in production, it's easy to install and use."

"This has been one of the most reliable storage systems that I have ever used."

Cons
"In our current configuration, we can only run the line controllers in high availability, active-standby mode, whereas we would like to see active-active implemented.""I would like to see the management layer improved.""The rail system that Pavilion uses to mount up into a standard Dell or APC cabinet extends further back than normal rails, and they cover up the zero PDU slot. So, I don't like the rail system that comes with the device. That is my biggest complaint."

"The only area I can highlight for improvement is that the 4:1 data reduction target has not been reached. This may be due to an issue with Dell EMC's initial analysis of data compression. As a result, we have had to add new physical disks to reach our goal of total available disk space.""Where the system needs to improve is by adding more enterprise features like replication on other sites. We would also like it to be much more aligned with the VMware version. For example, today we have two different versions of VMware ESXi running to keep the PowerStore online. It would be better if the software cycling was faster.""The price is on the higher side.""The upgrades themselves are running fine, but after the upgrade is when we have a problem. With the update to 1.4, we had a head crash. They told us, 'This is a known issue. Please upgrade to 2.' We upgraded to 2 and, one week later they told us, 'Yeah, there are some issues in 2.0.0. You can lose data. Please upgrade to 2.0.1.' Overall, they need to make the system stable.""The setup process could be improved. We had some issues regarding configuration and the time it took to do things. It wasn't specifically the people we worked with, but more the process and how it's done. They can work on that.""During the installation phase, the licensing part was not straightforward. It was very difficult for the technicians, who are not trained Dell EMC technicians, to do the licensing because the information on their website is not straightforward... Eventually, I had to pass this task to our business partner and they did it for us.""There is no Synchronize replication feature on the storage."

"The write performance could be improved because it is less than half of the read performance."

Pricing and Cost Advice
  • "This is hardware. They have a singular array that you can populate with your own disk, or you can buy the disks through them. For controllers, you pay for the components inside of the SAN, but there is only one chassis that they work with."
  • "The licensing fees are very reasonable."

  • "The price is not cheap, but it's worth it for the features you get from the storage. If you can afford it, you are probably buying the best solution that you can have for this virtual environment."
  • "There's still a cap on the upgrade path, where you can consume all the engines within the frame before you have to go to another frame... Normally, we exceed the IOPS on the frames before we can ever exhaust the storage, so anything they can do to help us avoid stranded storage capacity, capacity that we couldn't get to, would be beneficial."
  • "When we compared it with the other solutions, the pricing of PowerStore was equal. The pricing is good."
  • "The price of Dell EMC PowerStore could be better, it is a bit expensive."
  • "We only have a single machine and we are currently using half of the hard disk slots. We have asked for an upgrade for the rest of the hard disks but, from my point of view, it costs too much. We have 12 to 15 hard disks inside and if we try to upgrade only the hard disks, it costs the same as the complete system. This is something I don't understand."
  • "We are happy with the pricing that we get from Dell."

  • "We acquired VAST Data as a one-time, capital purchase."
