We performed a comparison between DDN IntelliFlash and VMware vSAN 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."Performance is the most valuable feature."
"NVMe data storage platform that's easy to set up and easy to use. It's stable, with a lower response time, and quick technical support."
"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."
"The scalability is good."
"We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent."
"What I like most about this solution, is the speed, resiliency and scalability."
"Support has been helpful."
"The most valuable feature is its data reduction."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"The initial setup is straightforward."
"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"
"High performance and ease-of-management are the most valuable features."
"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"
"It performed great originally, and when it performed great, it was awesome."
"Since the storage space is local to the hosts, it reduces the overall response time and improves the performance."
"While we haven't made major changes to our disaster recovery and business continuity processes yet, moving towards stretch vSAN across sites will simplify and expedite our DR processes in the future."
"The deduplication and compression are excellent."
"The solution is quite stable."
"Adding new nodes and expanding vSAN forward is simple and non-disruptive for a lot of our customers."
"The solution has high performance."
"If we decide to expand, vSAN could offer us some flexibility. We are researching ways to set this up from a new data center, which is located somewhere different from the current location right now."
"It's completely hyper-converged, so it's very convenient."
"In some cases, we get into very in-depth conversations around movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"I would like to see them develop the ability to integrate with more AWS services. There are increasingly more and more services coming out from AWS but there are also certain constraints where we can't move everything over to a cloud as well. We would like for things that are on-premise to be easily integrated with AWS."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"The price of Pure Storage FlashArray could be better."
"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."
"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."
"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."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases."
"The UI falls short compared to other solutions. It needs some development to make it more user-friendly."
"There is a lot that VMware could improve from a marketing perspective. The cloud is still new for many people, so extending storage should be effortless. It shouldn't be so complicated to extend the storage so workloads can access it no matter where they go."
"I'd like to see better integration with the Update Manager, with respect to firmware updates for hardware."
"There's a lot that can be done to segregate. That may be available now in vSAN 7, I suppose, however, the deduplication and compression can be segregated."
"Disaster recovery needs to be improved, when there is a crisis, there is a problem with what is the quickest way to get out of it."
"There could be more features with the automatic backup."
"I would rate the stability a seven out of ten."
