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."The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"It's simple, powerful, and ready to use."
"I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity."
"The deduplication and compression meet all of our system requirements."
"Access speed and power consumption are most valuable."
"The ease of use. That's what our customers love. They say it's very easy, they don't need special training, they don't need to call us or any other company or integrator to help them do their job. That's the main reason they purchase Pure."
"We consume less physical storage because of the solution’s deduplication and compression."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"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."
"For the migration process from the older VMAX arrays to PowerMax, we VMotioned everything. It was easy."
"We can consistently replicate mainframe and open system and have a single recovery point."
"I would rate my experience with the initial setup a nine out of ten, where one is difficult and ten is easy."
"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 PowerMax software and CloudIQ let us get an inside view of our compression and compaction, as well as our usage of the storage."
"It offers a high level of availability, so pretty much near zero downtime."
"The smaller footprint of the device has been really nice. We have gone from eight bays to one bay. Having one floor tile in our data center has been pretty awesome. A lot less power and HVAC cooling is being consumed."
"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 problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."
"In terms of the future, I have been excited by some of the copy data management stuff that they're talking about building into the environment. There are feature sets where I've done a lot of automation work. So, I am always looking forward to extensions of their API. They're also talking about a phone home centralized analytics database being used as a centralized management console with a list of new cloud features, but this doesn't seem finalized."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"Dell PowerMax NVMe is costly compared to other solutions."
"The REST API needs improvement. We are a very big automation company, and this would be big for us."
"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 to see continued visibility and analytics in the platform."
"They should work with the storage engineers to better tweak the management tools to give them improved visibility into their data."
"The initial setup process is difficult."
"Dell should work on their marketing strategies to make the product more visible on the market. They should promote the product's compatibility with IBM, as not everyone knows it."
"When it comes to Oracle and database workloads, data reduction could be a little bit better. Some of the competition, like Pure, have post-processes which do additional deduplication and compression on the backside; everything is in-line and then they do a secondary process. It would be a good option if you could start getting 5:1 or 6:1 data reduction on database workloads."
"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."
