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.
"This solution is very scalable."
"The most valuable feature is its speed."
"They have really good baked in analytics to show you trends for growth history, so it does help with future planning for data growth."
"Cost, racial per terabyte, and speed is why we chose PureStorage. It was no brainer."
"Technical support is good."
"I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity."
"The ease of use. That's what our customers love. They say it's very easy, they don't need special training, they don't need to call us or any other company or integrator to help them do their job. That's the main reason they purchase Pure."
"I like its speed. It has all the features that I need."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It performed great originally, and when it performed great, it was awesome."
"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."
"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."
"Data Compression: Up to 80% space reduction in the database"
"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."
"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."
"I really value deduplication and compression to save space."
"The replication feature provides another functionality to protect your data."
"Integration with VMware"
"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."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"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."
"It is not possible to create a cluster on top of multiple arrays."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"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."
"I would like to see more cloud integration."
"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."
"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."
"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."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"If the VNX had embedded encryption, that would be great."
"The CLI could be better documented, like with VMAX."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"Poor connection to FC."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"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."
"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."
