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 simplifies the overall management. We don't have to worry about storage anymore."
"I like the speed, and I like the API and how programmable it is."
"The stability and performance are the best things about the solution."
"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"It simplifies building out the storage."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"Very stable; no worries about how much it can handle."
"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."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"Data Compression: Up to 80% space reduction in the database"
"High performance and ease-of-management are the most valuable features."
"The initial setup is straightforward."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"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."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"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."
"The replication feature provides another functionality to protect your data."
"It is very stable even during multiple power failures."
"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."
"I really value deduplication and compression to save space."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"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."
"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."
"The file functionality could be better."
"It is a bit expensive."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"If they could make it cheaper, that would be something."
"The price of this solution could be improved."
"The solution could improve by having a multi-tenant feature."
"It's somewhat scalable, but maybe not so much as some of the competition."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"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."
"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."
"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."
"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."
"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."
"Poor connection to FC."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"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 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."
