We performed a comparison between Dell PowerMax NVMe and VIOLIN QV2020 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."I like the speed, and I like the API and how programmable it is."
"The most valuable feature is its upgradeability."
"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"The compression and deduplication features help to make the best use of the capacity."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"We consume less physical storage because of the solution’s deduplication and compression."
"It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."
"We find the ease of usability and setup valuable."
"My storage engineers are very happy with PowerMax. They are very pleased with the performance, decreased latency, and dependability. From the team, the RESTful API makes management so much easier for them versus the command line interface."
"The number one most valuable feature is reliability. I want to go home at the end of the day and come in the next day knowing it works, especially since we have storage offshore."
"They're basically tanks. You could take a baseball bat to the thing, and it's still going to keep running and doing what it's supposed to do. We've had a couple of part failures, and you can pretty much replace any part on that thing at any time during the day in the middle of production without worrying about anything happening."
"It has reduced our footprint in different physical locations."
"It is a scalable solution. Scalability-wise, I rate the solution a ten out of ten."
"There is no management overhead involved in optimizing performance. It does it so well on its own. We don't have to manage much at all. It really is like a set it and forget it solution. My storage engineers love the system. It is a lot less work than our previous systems, which weren't bad by any means. There is not nearly as much management as before. So, we are saving dozens of hours per month for our storage team, and that is a real cost in our business."
"We removed the need to observe whether we ran into issues with the performance of disks or number of IOPS. Previously, our Oracle Database would throw us performance errors. Now, with PowerMax, everything runs smoothly."
"We use ESRS for our call-home, and a lot of times, Dell EMC will respond to the issue before we even know it."
"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."
"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."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"I would like to see more cloud integration."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"The integration capabilities could be improved."
"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"I would like them to continue improving the management tools and continue moving towards a RESTful API versus CLI."
"The initial setup was complex. ESRS is a very complex solution to put into our environment, because it requires external access to the Internet. That's a very tough thing for us to do, because we are a PCI and PII company. We store a lot of data for people which is personal. Therefore, going out to the Internet is not our preferred path."
"We've had a couple of little things come up, but for the most part, they've been pretty stable."
"They can make the GUI better, especially for the ones that come out of the box. We did encounter a bit of difficulty in setting up the storage. We had to deploy Solutions Enabler on a Linux machine to be able to fully interact with the storage. They need to upgrade the web interface for the management of the storage that comes out of the box. The management interface for NFS is also a bit old and not very intuitive."
"It's a relatively new product, but for the next release I would like to see higher bandwidth on the front-end adapters. This would allow even greater scalability for critical workloads and consolidation for non-critical workloads. The hosts may not require that level of I/O performance today. However, it allows us to scale physical non-cloud environments without large investment."
"I would like a more informative CloudIQ for iOS. What you can see via the web UI significantly differs from what you can see via the web application."
"The price could be lower, and we are unhappy with the price."
"PowerMax's software is highly stable, but we faced two hardware issues in one year. We had a failure of the storage director module, and the physical disk failed on another occasion. Dell EMC should improve its hardware quality."
"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."
