We performed a comparison between DDN IntelliFlash and VIOLIN QV2020 [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."Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The most valuable features of this solution are its ease of use and performance."
"One of the best features is the support, which is excellent."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"The initial setup was extremely simple and straightforward."
"Technical support has been helpful and responsive."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"High performance and ease-of-management are the most valuable features."
"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."
"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's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It’s simple to use hardware to fix performance issues. Our issue is poor coding/queries. This greatly speeded things up. It’s too costly to track down poor programming in applications. The price of a developer’s time to scan through all the coding is high compared to buying Violin."
"VIOLIN QV2020 is the latest in terms of performance. It has high-speed data access and processing capabilities, distinguishing it as a leader in its storage solutions category."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"The software layer has to improve."
"We need better data deduplication."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"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."
"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."
"I set up Wi-Fi for storage, and since then, we haven't experienced any interruptions in service."
"VIMM replacement is poorly designed. You have to slide out an entire drawer, remove the cover and then pop out the failed VIMM. I would like to see a front replacement just like with hard disks. This leaves room for error; for example, when you slide it out from the rack, you are moving cables along the cable management arm. This leaves the possibility of accidentally unplugging a cable from the array if it is not seated properly. Also, you might pinch the cables when sliding it back into the server rack."
