We performed a comparison between DDN IntelliFlash and VNX [EOL] 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."It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"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 system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The most valuable feature of this solution is its ease of use."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"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."
"What I really like about this program, is that it is easy to use and easy to configurate."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"Data Compression: Up to 80% space reduction in the database"
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It performed great originally, and when it performed great, it was awesome."
"The initial setup is straightforward."
"High performance and ease-of-management are the most valuable features."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"I really value deduplication and compression to save space."
"From my point of view, the configuration that I can sell is restricted to the EMC best practices. It is hard to make a mistake in a solution. It means the configuration has good performance and scalability options."
"One of the best features of the VNX is the ability to combine drives of different types into a virtual Storage Pool. By combining small but fast flash drives, SAS drives, and high-capacity but slower NL-SAS drives, the VNX can intelligently move data to the different tiers of storage based on usage."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"Multi-tiering, positively affects the efficiency of the storage space."
"It is very stable even during multiple power failures."
"The replication feature provides another functionality to protect your data."
"In terms of what needs improvement, the dashboard and management could be simplified."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"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."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"I'd like to see the product implement active replication for vehicles such as VMware."
"The tool's portfolio is minimal. It is expensive."
"Snapshots are not as easy to access as on a NetApp device."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"It's somewhat scalable, but maybe not so much as some of the competition."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"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."
"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."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."
"The CLI could be better documented, like with VMAX."
"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."
"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."
"Poor connection to FC."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"It would be very helpful to get an automated report that shows you the size of the checkpoints and get warnings when a checkpoint is reaching either maximum capacity per a file system or hitting the ceiling on the SavVol pool consumption."
