We performed a comparison between Dell PowerStore 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 most valuable features are the replication of data and the continuous snapshot that we can take from the disc."
"It reduces space and the polar consumption. It also accelerates the application."
"We put a fair amount of stress on it because we run sequel workloads and we run web applications where the same web files are hit over and over. We have had almost zero stability issues with that SAN, that has been really great for us."
"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance. Our internal clients are happy."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"Provides fast access and is user-friendly."
"The most valuable feature is that maintenance is free."
"Pure Storage FlashArray has significantly improved our data center performance. It handles high workloads efficiently, providing better performance in the environment. With increased storage capacity, it has led to improved overall system performance. The tool's technology is a standout feature. It has helped me reduce storage costs by 15 percent."
"This solution is very useful to us as we use it internally for all of the services that we need. We use it as a lab and we showcase new technology to the customers and how it can help them going forward."
"The support is very good."
"A particularly valuable feature is its simplicity."
"The simplicity and ease of use have been very valuable features. I have a very small team, and only half of the team is well versed in the HP product. Whereas if I bring PowerStore in, everyone can learn it because it will be new on the floor."
"Pricing is very good. It's very competitive against those of all the others that I looked at in the marketplace, such as Hitachi, IBM, HP, and Pure. Dell is right there in the mix as far as providing the best price point as well as meeting the performance requirements that we have."
"The compression is excellent."
"For access from virtual machines, iSCSI, and NFS, it is very good. It helps increase performance."
"Gives us flexibility, performance, and ease of use. It also has some very good compression capabilities. We were looking for a solution that was easy to install in our VMware environment, that was flexible. PowerStore X is a type of a VMware cluster that you install inside your environment. If you have a VMware environment, like we have in production, it's easy to install and use."
"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."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"A year ago they promised that they would be able to read through the database encryption with more metric and they have not delivered on that patch, which is significant because it gives us back so much more storage room. We want to be able to read through the encryption."
"We haven't seen ROI."
"In the next release of the solution I would like to see Vormetric native block encryption."
"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."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"They could improve the price."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"PowerStore's management console could be improved."
"It needs more mature code."
"I have not seen anything specific. The only thing I can think of that needs improvement is the price."
"Dell PowerStore is a good solution overall, but some models could support hypervisors better by allowing for more customization and flexibility for customer needs."
"More demonstration and training options are needed."
"You cannot delegate permissions."
"The price is on the higher side."
"The storage could be improved. I would like a feature for how to best secure an appliance and the storage since we are connecting the container to the public cloud. I would like them to develop another level of security, making it more secure than from what they have now."
"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."
