We performed a comparison between Dell PowerMax NVMe and VAST Data 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."It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"The most valuable feature of this solution is reliability."
"Technical support has been helpful and responsive."
"The high availability of the product is the most valuable feature."
"It allows us to protect our data using different data centers and replicate bi-directionally between our two main data centers."
"Enterprise Cloud Storage is the most valuable feature, along with the data services which come with it, plus the deduplication and compression."
"It is a true, stable product."
"Technical support has been excellent."
"The solution has good operability and easy scalability."
"The PowerMax software and CloudIQ let us get an inside view of our compression and compaction, as well as our usage of the storage."
"It is a scalable solution. Scalability-wise, I rate the solution a ten out of ten."
"We were able to move away from a middleware solution for high availability, going right to snapshots and data replication on arrays."
"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'd like to see the product implement active replication for vehicles such as VMware."
"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."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"It is on the expensive side."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"We need better data deduplication."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"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."
"I would like to see continued visibility and analytics in the platform."
"Dell can improve the Service Level Agreement (SLA) compliance. Sometimes, when we need to replace a component, the SLA says four hours, but for some reason, the technician doesn't arrive until the next business day or even six to eight hours later before the case is placed. So, focusing on respecting the SLA is where Dell could improve."
"Support of the product can be slow and an administrative challenge: planning, scheduling, and overseeing data center access for a Dell EMC rep. One improvement could be to enable a self-maintenance option. The requirements that we go through to get Dell EMC onsite to replace failed drives, power supplies, and other small redundant parts can be unnecessarily complex. If simplified, they could send us the parts, then we could replace them much faster, more easily, and truly within the SLA parameters."
"Firmware updates are a bit painful because you have to involve their support, as opposed to having the ability to do it yourself."
"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."
"I would like NVMe to be end-to-end in the next release. Right now, it is not end-to-end."
"We brought up this question to the implementation engineer. We were comparing use cases where a customer is using RecoverPoint, then goes to PowerMax. In our previous setup with XtremIO, we were using RecpverPoint and keeping snapshots for 30 days, every few seconds. With PowerMax, I requested this for every 15 minutes, keeping it for a week. The engineer's answer was, "There will be too many snapshots. It might slow down the system." This is specifically for the use cases where there is RecoverPoint. While PowerMax works with RecoverPoint, and you can use it, there should be some way where you can have even more snapshots and not to worry about performance and system cache."
"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."
