We performed a comparison between DDN IntelliFlash and Dell PowerStore based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The deduplication and compression rates are beyond impressive."
"Pure Storage is extremely reliable — it's never failed."
"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"The tool has reduced our power consumption."
"This solution has improved our organization in the way that we used to see latency but now with this solution we don't. It also has good performance. Latencies have come down for our performance in the SQL databases. We can put a lot more in a lot less in terms of space savings. We also save data center space have good deduplication."
"It worked flawlessly."
"It simplifies storage."
"Data Compression: Up to 80% space reduction in the database"
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"High performance and ease-of-management are the most valuable features."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It performed great originally, and when it performed great, it was awesome."
"The initial setup is straightforward."
"The solution is stable."
"The most valuable feature of the solution for me is the deduplication part, especially since most of the servers in our organization are Windows-based servers."
"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."
"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."
"For access from virtual machines, iSCSI, and NFS, it is very good. It helps increase performance."
"The supportability of SCME drives for faster data access from the PowerStore and is the most valuable feature."
"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..."
"It provides a big benefit when upgrading a new VMware environment. For example, in a big environment with 10 to 30 ESXs, you can take everything and put that into PowerStore. So, it is cost-effective, which is very important and has been massive for us. You reduce almost 80% from the hardware and work directly from PowerStore. Building hardware, especially in a big VMware environment, is a big issue for my organization."
"I would like to see more cloud integration."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"They have a product, FlashBlade, which is their object storage integration, and that's something that we haven't integrated with yet. This might be an area for additional focus as it would play into scalability, because the very nature of object storage is that it's infinitely scalable."
"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"It's somewhat scalable, but maybe not so much as some of the competition."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"While using Dell PowerStore's interface in our organization, we sometimes miss out on some information."
"The solution's pricing could be better."
"The solution only does thin provisioning."
"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."
"The customer service and support are bad."
"There are certain shortcomings with the technical support team of Dell PowerStore, where improvements are required."
"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."
