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 of Pure Storage FlashArray are the management view of the solutions, ease of provision, and deprovision, it is fantastic."
"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"Support has been helpful."
"Performance is the most valuable feature."
"Technical support is good."
"Before we used Pure Storage it took 93 days of employees who run the database to back up and restore databases. The scale of deployment basically went from several days to a few minutes."
"The sales and executive support have been outstanding compared to the rest of the market... My upgrade paths have been simple on the Pure... It's a lot simpler to implement and a lot simpler to manage."
"Processes that used to take 40 minutes to two hours can be completed in five minutes."
"PowerStore is easy to use. All the drives use soft encryption. To upgrade it, you download the app, and it runs by itself. It's very easy to deploy, share, and create volumes."
"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 way you're able to manage all your PowerStores as one solution is very good for us. PowerStore enables you to federate or cluster multiple appliances with automated load balancing. In terms of management, it's helpful that we can do it from a single interface where we're able to manage multiple PowerStores. When you have multiple PowerStores it works intelligently by running the workloads based on the needs of the infrastructure."
"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."
"Dell EMC PowerStore is scalable."
"The most valuable feature is that it is easy to use this frame. I am a SAN administrator, but I was able to train my colleague, who had only been a VMware administrator, on the PowerStore in about half a day. Now he's autonomous in assigning volumes and creating data stores..."
"The most valuable feature of the solution for me is the deduplication part, especially since most of the servers in our organization are Windows-based servers."
"Its flexibility is valuable because we have had some moments where we had to adapt, and it has been quite flexible."
"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."
"The price of the solution can improve."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"The 3PAR SSD arrays that we have are still failing a lot so even though we're under warranty, we still have to get someone out and usually have someone troubleshoot so that usually adds onto the cost. With Pure, we've had a disc fail and we pop it out and you pop it in and it's good to go."
"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."
"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."
"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 see data tiering to AWS."
"The only area I can highlight for improvement is that the 4:1 data reduction target has not been reached. This may be due to an issue with Dell EMC's initial analysis of data compression. As a result, we have had to add new physical disks to reach our goal of total available disk space."
"The upgrades themselves are running fine, but after the upgrade is when we have a problem. With the update to 1.4, we had a head crash. They told us, 'This is a known issue. Please upgrade to 2.' We upgraded to 2 and, one week later they told us, 'Yeah, there are some issues in 2.0.0. You can lose data. Please upgrade to 2.0.1.' Overall, they need to make the system stable."
"The customer service and support are bad."
"There is no Synchronize replication feature on the storage."
"It's also only supported with a limited amount of switches."
"The solution's pricing could be better."
"After the smooth launch of the product in our company, only the areas around upgrades are a bit problematic. In our organization, we face difficulties when updating the product."
"While using Dell PowerStore's interface in our organization, we sometimes miss out on some information."
"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."
