We performed a comparison between DDN IntelliFlash and VAST Data 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."We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"The reliability is very good."
"What I like most about this solution, is the speed, resiliency and scalability."
"Support has been helpful."
"The solution helps to simplify storage."
"It is easy to deploy and it's all-flash, so it's very fast."
"We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent."
"The initial setup is very straightforward. You simply plug it in and turn it on."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"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."
"Data Compression: Up to 80% space reduction in the database"
"The initial setup is straightforward."
"High performance and ease-of-management are the most valuable features."
"It performed great originally, and when it performed great, it was awesome."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"Pricing could be better in comparison to other solutions."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"I would like to have support available in Spanish."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"The technical support is okay, but could be improved."
"In the next release of the solution I would like to see Vormetric native block encryption."
"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."
"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."
"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's somewhat scalable, but maybe not so much as some of the competition."
"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."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
