"For access from virtual machines, iSCSI, and NFS, it is very good. It helps increase performance."
"This solution is very useful to us as we use it internally for all of the services that we need. We use it as a lab and we showcase new technology to the customers and how it can help them going forward."
"I like the performance of the PowerStore. When you talk about PowerStore, it's mainly about flash systems and high-end IOPS. The 1000T is a midsize box, in terms of the way the vendor positions it, but it is more than enough for our needs."
"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."
"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."
"The most valuable feature is that it is easy to use this frame. I am a SAN administrator, but I was able to train my colleague, who had only been a VMware administrator, on the PowerStore in about half a day. Now he's autonomous in assigning volumes and creating data stores..."
"The solution is extremely stable."
"The supportability of SCME drives for faster data access from the PowerStore and is the most valuable feature."
"The efficiency ratio is just as high as advertised. It's very high relative to other storage solutions as well. The compression and deduplication capabilities are also very high."
"Overall, the solution is strong, easy and fast."
"It was very new when we first deployed it a year ago. Even the upgrade processes and knowing what to expect, as well as documentation, could be more robust."
"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."
"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 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."
"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."
"There is no Synchronize replication feature on the storage."
"The NAS part is very poor. It's very basic. Even Dell EMC has said that to us. We are waiting for version 3 of PowerStore for that. This must be improved and it is in the roadmap."
"It's also only supported with a limited amount of switches."
"One improvement I am hoping for in the next release is unified storage."
"For mission critical issues the performance is low."
