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, Pure Storage and others in All-Flash Storage."Data deduplication features make it easier to manage storage and forecast growth."
"The ease of management is one of the most valuable features of this solution. I would have also said that it's pretty fast but now our SQL servers are starting to beat it up pretty bad."
"The solution is very reliable."
"The most valuable feature is how it simplifies the management of the SAN."
"It's just very easy for general block storage."
"It is all-flash. This makes it a lot faster than the rest of what we have, as it is able to drive high I/O loads, which is big for us."
"This solution has improved our organization. In the past, we had reports that were taking up to two hours and after switching to SSD storage the overall processing power dropped to half an hour. The end users saw an immediate performance gain."
"Processes that used to take 40 minutes to two hours can be completed in five minutes."
"First, it's an enterprise storage solution. This is very important for us. Another important feature is replication."
"We were able to move away from a middleware solution for high availability, going right to snapshots and data replication on arrays."
"This platform is reliable in supporting our data availability. We now have a higher performing platform and have been able to consolidate our workloads into one single platform."
"The product is very fast and reliable."
"It is a scalable solution. Scalability-wise, I rate the solution a ten out of ten."
"Key features include performance, replication time, and dedup and compression."
"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."
"PowerMax, with version 9.02, which we installed recently, has some very good features, such as CloudIQ."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"The backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release."
"The integration capabilities could be improved."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"The GUI could improve, it could be more intuitive. There is hidden functionality."
"It is not possible to create a cluster on top of multiple arrays."
"Storage. There could be better storage."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"The NVMe integration could be improved."
"Some of the management features could be simplified and that's probably the main thing they need to address."
"There are definitely some improvements that can be made to the CloudIQ."
"Since the merging of EMC and Dell into Dell Technologies, there has been a hurdle that they've had to overcome, and they're not over it yet. It takes two to three times longer for things to get fixed than it did when they were separate companies. That is something that has to be fixed."
"I would like it to support NVMe over Fabrics, because that is the next item for consideration on the NVMe roadmap. PowerMax supports NVMe on the back-end, but when it starts supporting NVMe over Fibre Channel, suddenly various hosts can directly communicate with PowerMax, and with NVMe-oF, as well. Suddenly, Gen 6 and Gen 7 switchers will be able to help facilitate that particular communication channel."
"There is some room to grow, especially with some of the installation quirks."
"The tool is costly compared to other similar products. The product's pricing needs to be improved. I would like the product to include the replication feature in its future releases."
"Dell PowerMax NVMe needs to increase storage and improve scalability."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
Dell PowerMax NVMe is ranked 8th in All-Flash Storage with 66 reviews while VAST Data is ranked 18th in All-Flash Storage with 2 reviews. Dell PowerMax NVMe is rated 8.8, while VAST Data is rated 10.0. The top reviewer of Dell PowerMax NVMe writes "Simplified storage provisioning for us, enabling us to assign any volumes in two to three minutes". On the other hand, the top reviewer of VAST Data writes "Stability-wise, a device that has been up and running for years". Dell PowerMax NVMe is most compared with Dell PowerStore, IBM FlashSystem, Dell Unity XT, Huawei OceanStor Dorado and Dell XtremIO, whereas VAST Data is most compared with Pure Storage FlashBlade, NetApp AFF, Qumulo, Dell PowerScale (Isilon) and DDN SFA7990X.
