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 easy to use, and the maintenance upgrades to get free controllers work really well."
"It is noticeably easier to manage than other appliances that we have."
"Technical support has been amazing."
"The most valuable features are the replication of data and the continuous snapshot that we can take from the disc."
"The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."
"The solution has probably reduced my power use substantially."
"It simplifies the overall management. We don't have to worry about storage anymore."
"The mobile app is very helpful."
"High performance and ease-of-management are the most valuable features."
"The initial setup is straightforward."
"It performed great originally, and when it performed great, it was awesome."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"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 has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"It is very stable even during multiple power failures."
"Integration with VMware"
"I really value deduplication and compression to save space."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"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 most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"There are many features which need to be added, particularly on the replication side."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography."
"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."
"The price of this solution could be improved."
"In the next release I would like to see integration into other third-party player providers like Google."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"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."
"Poor connection to FC."
"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 scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"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."
"If the VNX had embedded encryption, that would be great."
