Featured Reviews

Eugene Hemphill - PeerSpot reviewer
Helps to save money and resources with the data compression feature
One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.
Syed Habib - PeerSpot reviewer
Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.
Nabeel Sayegh - PeerSpot reviewer
Supercharges enterprise storage by way of highly optimized hardware, comprehensive data management and a feature rich interface.
During their early years, I was a member of Pure's Customer Advisory Board. In addition, when we first adopted Pure, they did not have replication GA yet. We got into their beta testing program and help them work out certain issues with that technology. One weakness I can say the array has, still to this day, is limited control on scheduling snapshots. Depending on the type of replication schedule you are building, you may or may not have control on specifying the start time of a given replication schedule. This is not a very big problem in the grand scheme of things, but something nonetheless that has bothered me about the scheduler in general. Another area for improvement would be automatic host alias creation. Other platforms such as EMC Unity/PowerStore will automatically detect the host name, create a alias for it and associate the logged in HBA's to it. Pure does not do this for you and as a result, requires manual configuration. This can be very time consuming especially when you are deploying a large number of new servers.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"One of the best features is the support, which is excellent."
"The most valuable feature of this solution is its ease of use."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The solution uses newer technology for deduplication and compression."
"I appreciate the performance."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"We run about 100 virtual servers on it. We have about 100 users accessing the file shares from there, and I've seen no problem with that. We have about a 10GB backbone. Whatever we throw at it, it hasn't shown any sign of weakness or anything. It's been really good."
"The Snapshot feature is key."
"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example. It depends on you use it, but for our purposes, we find Unity simple to use."
"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."
"It is easy to manage overall. It is all web-based. It has a an easy, nice dashboard. I receive emails if there are issues. When there are any updates, I receive emails. I can either do them on my own, but normally I schedule them with Dell EMC and they remote in, then it's done."
"User friendly interface"
"It has the same operating system for both file and block, and it actually simplifies everything. And it's much smaller compared to VNX."
"We put the Unity on one of the file servers and the backup performance improved quite a lot."
"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."
"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."
"Provides fast access and is user-friendly."
"The compression rate is one of the most valuable features of Pure Storage FlashArray. Additionally, it is all-flash storage with excellent IOPS, and hardware failures are very less."
"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"It has good stability for our company."
"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"They are quite responsive and our local team was pretty good."
 

Cons

"The software layer has to improve."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Adding some functions to the product would be beneficial."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The solution should include a free process in the HPE portal that uses serial numbers to verify that hardware is genuine."
"It could be a little easier to attach it to a network file system."
"Ordering is easy, but the processing site and working with those companies was difficult."
"We'd like to see a cheaper version of an all-flash array in that footprint."
"The VNX reporting is much more granular, versus the Unity reporting."
"Data replication needs improvement as the future roadmap for RecoverPoint appliance is not there."
"This solution could be improved by offering containerization. This is something many of my customers are looking for."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"If they could make it cheaper, that would be something."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"In the next release of the solution I would like to see Vormetric native block encryption."
"There are many features which need to be added, particularly on the replication side."
 

Pricing and Cost Advice

"The support cost per array is about $20,000 a year for 24/7 support."
"Our licensing fees are $500,000+ USD."
"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."
"The product is expensive."
"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"Given its price, Pure is not the first option."
"The licensing is on a yearly basis."
"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."
"There is not a license required for the use of the solution. We purchased a maintenance contract."
"While Dell EMC is costly, I don't have any complaints about their licensing model."
"Licensing is a little bit confusing. Going through everything with them, there are a lot of line items to go over. Every single thing is broken down into a line item, and it starts to get really confusing in terms of what we're actually purchasing when it comes to the product."
"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"For us, as the customer, it reduced the price of the management."
"There are no licensing fees or other costs."
"We have seen a reduction in TCO."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"It is light years beyond anything else with the same price point."
"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
