We performed a comparison between Dell EMC PowerStore and IBM FlashSystem based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: When compared, both solutions received similar ratings in all categories except for service and support. Users of IBM FlashSystem were more satisfied with the service.
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"It has benefited my organization because it has reduced time to insights."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"The high availability of the product is the most valuable feature."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"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."
"It is very easy to use. Access is very friendly. It shows you a lot of important information at the first glance. It has been very easy to use."
"The solution is extremely stable."
"The solution is easy to use and has good performance."
"The compression is excellent."
"The product's initial setup phase was very easy."
"Dell EMC PowerStore is scalable."
"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."
"The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."
"User friendly management interface."
"FlashSystem offers proven technology in a compact package."
"The speed, performance, and stability are the best features of IBM FlashSystem."
"The most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."
"The compression and deduplication features are the most valuable."
"Most of the features for the reduction in data compression are useful. It is also very easy to use and administer. Its performance is also good."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"They could add more support for file storage and different types of storage."
"The software layer has to improve."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"The tool's pricing is higher than competitors."
"After the smooth launch of the product in our company, only the areas around upgrades are a bit problematic. In our organization, we face difficulties when updating the product."
"We are looking for the Dell PowerStore to become more mature to maximize our use cases."
"It needs more mature code."
"Could be improved by including a synchronizing feature for the file systems."
"I have not seen anything specific. The only thing I can think of that needs improvement is the price."
"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."
"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."
"The solution only does thin provisioning."
"The storage capacity of this solution could be improved."
"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."
"Our model does not support compression or deduplication."
"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."
"The solution's infrastructure technology level could be PCI Express 5 instead of PCI Express 4 for the next version."
"It has room for improvement in the area of stability."
"The initial setup is complex."
"The pricing needs to be more competitive."
