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."Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"Provides fast access and is user-friendly."
"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"I use all the features of this solution and I find them to be easy to use and functional, such as the compression and capacity to expand."
"Performance, deduplication, compression, and fast response time for requests from servers and applications."
"The most valuable feature is its data reduction."
"Access speed and power consumption are most valuable."
"The speed is the most valuable feature, along with the ease of getting it connected. We were able to get it online in less than a day."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It performed great originally, and when it performed great, it was awesome."
"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"
"The initial setup is straightforward."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"High performance and ease-of-management are the most valuable features."
"Multi-tiering, positively affects the efficiency of the storage space."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"Integration with VMware"
"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."
"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."
"They should work on their upgrades, they're not smooth."
"The price could be better."
"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."
"The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."
"There are a lot of things to improve."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"I would love for them to have a hyper-converged solution."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"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."
"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."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do 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."
"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."
"If the VNX had embedded encryption, that would be great."
"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."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does 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."
