We performed a comparison between DDN IntelliFlash and Hitachi VSP E Series based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Hitachi Vantara and others in NVMe All-Flash Storage Arrays."Redundancy and the fault tolerance of the platform are the most impressive."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"I never have to worry about its performance or if it is the root cause of an issue."
"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"All updates, upgrades, and hardware work are all performed on-line with no impact."
"Their support system has insight into errors on our SAN fabric that we can't see. They've brought attention to and raised awareness for us about things that we couldn't see, when we were experiencing problems."
"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"Data Compression: Up to 80% space reduction in the database"
"The initial setup is straightforward."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"High performance and ease-of-management are the most valuable features."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"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."
"It offers good file sharing."
"We are using the Hitachi VSP E Series for high IOPS."
"Its user-friendly configuration and maintenance processes contribute to its reputation for being straightforward and easily manageable."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"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."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"The price of this solution could be improved."
"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."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"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."
"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."
"There is room for improvement in simplifying the overall complexity of the environment."
"The solution's support duration or end-of-support life is very short."
"The graphical user interface is somewhat outdated, lacking some of the modern features found in other solutions."
