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

"The database workloads are pretty fast because I frequently move data from here to there."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"Everything, especially the VMs inside, is pretty fast."
"Technical support has been helpful and responsive."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The initial setup was extremely simple and straightforward."
"The high availability of the product is the most valuable feature."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The compression and deduplication that will be coming in version 4.3. With just those features, you're reducing the amount of data and the footprint on the hardware."
"You can add volume and it's automatically registered in VMware."
"We like the way it integrates with our environment. These features help us use multiple soft applications. The new features of going off the grid and replicating really help us. They give us an advantage versus traditional storage resources."
"It is ease to use. It performs. It's easy to provision, and It's stable."
"It's easy to handle for administrators and it's a unified system. It's not as complex as Celerra systems or CX4 Clariions to administrate. You can do everything with one GUI."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"Via a click, we can deploy a data store or LUN to the ESX host. We can also deploy VVOLs to the ESX server."
"We can sleep at night because the support is great."
"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"The most valuable features of Pure Storage FlashArray are management and administration user-friendliness, provisioning, and performance."
"The most valuable feature is that maintenance is free."
"The most important feature of any storage array is its reliability, measured by its uptime."
"FlashArray's data reduction and NAS features are incredible. Its performance is the best I've worked with."
"Pure Storage FlashArray offers numerous valuable features, such as low latency and high throughput."
"The initial setup was straightforward in the way that it was a database vacuum storage."
"This solution is very scalable."
 

Cons

"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."
"Maybe the price can be reduced since the solution is very expensive."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"Adding some functions to the product would be beneficial."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"It could be a little easier to attach it to a network file system."
"I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good."
"A customer had to buy VMX because Unity didn't have WORM."
"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."
"I think Dell EMC should be more careful in appointing partners, and they need to have better control over their partners. And if their partner has some problems with them, we should not suffer."
"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."
"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems."
"It is not possible to create a cluster on top of multiple arrays."
"Pure Storage support could be a little better."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."
"Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing."
"They could improve the price."
"They have a product, FlashBlade, which is their object storage integration, and that's something that we haven't integrated with yet. This might be an area for additional focus as it would play into scalability, because the very nature of object storage is that it's infinitely scalable."
"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
 

Pricing and Cost Advice

"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."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"With VMware, we pay $300,000 annually."
"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."
"Our licensing fees are $500,000+ USD."
"We pay approximately $50,000 USD per year in licensing fees."
"The support cost per array is about $20,000 a year for 24/7 support."
"Most licenses for the solution are free but upgrades are available when adding additional software or storage."
"The product’s pricing should be improved."
"With the large Unity that we bought, it has saved us about one and a half rack space. That's our return on investment on our flash array. We also need less Fibre Channel connectivity."
"The price is good for commercial grade storage arrays."
"We have to apply for a license for each system."
"The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"The solution should be cheaper."
"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
"There are no licensing fees or other costs."
"The price is reasonable."
"FlashArray is expensive, but the quality justifies the price."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"It's expensive, but you get what you pay for."
"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
