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 most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"The most valuable features of Pure Storage FlashArray are the management view of the solutions, ease of provision, and deprovision, it is fantastic."
"Data reduction and compression. Sub millisecond latency."
"Very stable; no worries about how much it can handle."
"Performance is the most valuable feature."
"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions."
"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."
"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"High performance and ease-of-management are the most valuable features."
"Data Compression: Up to 80% space reduction in the database"
"It performed great originally, and when it performed great, it was awesome."
"The initial setup is straightforward."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"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 most valuable features of Dell PowerStore are the support for NVMe and SCM, which provides end-to-end performance and high IOPS, minimizing latency. It is a full-fledged storage solution."
"For access from virtual machines, iSCSI, and NFS, it is very good. It helps increase performance."
"The deduplication functionality provided by the solution is fairly good. The speed offered by the product is enough for our organization."
"The initial setup was straightforward."
"It has its own file formatting protocol, which saves a lot of space."
"Its flexibility is valuable because we have had some moments where we had to adapt, and it has been quite flexible."
"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."
"I would like to see them lower the costs."
"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"The price of Pure Storage FlashArray could be better."
"Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing."
"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"The price of this solution could be improved."
"The GUI could improve, it could be more intuitive. There is hidden functionality."
"I would like to have support available in Spanish."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"When you create a case on Dell's support website, you don't always get someone who is experienced in the kind of systems you need help with...making it an area where Dell's support team needs to make improvements."
"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."
"It needs more mature code."
"PowerStore's management console could be improved."
"I do not like having to use VPLEX for synchronous replication, as opposed to having the store software built-in."
"Could be improved by including a synchronizing feature for the file systems."
"Dell PowerStore is a good solution overall, but some models could support hypervisors better by allowing for more customization and flexibility for customer needs."
"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."
