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."What I like most about this solution, is the speed, resiliency and scalability."
"I like the speed, and I like the API and how programmable it is."
"The management features are well organized and they have a very good dashboard."
"The stability and performance are the best things about the solution."
"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."
"At this point, I don't know anything that they could provide in a better way."
"It has improved my organization because now have lower latency, we get fewer complaints from customers, and we see a constant response time."
"The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."
"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"
"It performed great originally, and when it performed great, it was awesome."
"The initial setup is straightforward."
"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 has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"It is very stable, even during multiple power failures."
"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."
"Multi-tiering, positively affects the efficiency of the storage space."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"I really value deduplication and compression to save space."
"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."
"It is very stable even during multiple power failures."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"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."
"I would like to see data tiering to AWS."
"In the next release I would like to see integration into other third-party player providers like Google."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"It is a bit expensive."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"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."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"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."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"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."
"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."
"Poor connection to FC."
"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 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."
