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 is an easy to use product for all of my team members."
"The most valuable features of Pure Storage FlashArray are management and administration user-friendliness, provisioning, and performance."
"It is the SAN backbone for our company."
"Having an intuitive user interface to get things running is great."
"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 is easy to deploy and it's all-flash, so it's very fast."
"The all-flash disc is the most valuable feature of this solution."
"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."
"It performed great originally, and when it performed great, it was awesome."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"The initial setup is straightforward."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"High performance and ease-of-management are the most valuable features."
"Data Compression: Up to 80% space reduction in the database"
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"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."
"It is very stable even during multiple power failures."
"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."
"Multi-tiering, positively affects the efficiency of the storage space."
"I really value deduplication and compression to save space."
"Good performance for VM environments"
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"Going forward, don't complicate things for the customers."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"The primary drawback is the cost, which can be prohibitive for small configurations."
"Currently, the solution fails to support file screening."
"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."
"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."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"If the VNX had embedded encryption, that would be great."
"There is an easy replication process between distinct data centers via VPLEX and/or RPA. But I hope in the future that EMC/Dell could replicate this with other types of storage."
"The CLI could be better documented, like with VMAX."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"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."
"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."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"There is no easy way to defrag a RAID group. It would be nice to be able to reduce the size of a storage pool if the storage is not needed anymore."
