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 FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"It has good, reliable, fast storage."
"Overall stability is very good. It is a very stable solution."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The valuable features of Unity include that it's flexible, has a friendly user-interface, and provides good performance."
"We have simplified it down to where we're using one storage pool inside the Unity, whereas on the VNX, we had multiple storage pools. This has simplified that aspect for us. It would depend on each organization. We're heavy into VMware and this ties into it so simply. It's made it a lot easier for us. I create a datastore inside Unity, it just shows up in VMware. I love that tie-in."
"It is very stable."
"The Snapshot feature is key."
"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 Unisphere management interface: We are very familiar with it. It manages all the EMC devices that we have. Management is easy because it is part of Unisphere, which is self-learning."
"VMware integration: Grants both the Storage and Virtual Administrator the ability to create and mount datastores, or even to check how much space each VM is consuming."
"It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNS. We just have to add and configure the storage in one place and it takes care of everything, which is very handy."
"Pure Storage FlashArray's overall speed is its most valuable feature."
"The availability and ease of use are the big features."
"One of the features that my customers are really interested in is immutable snapshots. There are immutable snapshots to which your applications can be reverted back if you are hit by some kind of ransomware threat or malicious attack. That's kind of a key deal, and it is one of the selling points I use to point out to my customers the value and the features that Pure Storage brings to the table."
"Their REST API is wonderful, well-documented, and easy to use."
"It is noticeably easier to manage than other appliances that we have."
"The all-flash disc is the most valuable feature of this solution."
"I appreciate the ease of provisioning storage on Pure Storage FlashArray."
"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance. Our internal clients are happy."
 

Cons

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"The tool's pricing is higher than competitors."
"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."
"I'd like to see the product implement active replication for vehicles such as VMware."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"I would like to see replication and DR features in the next release of this solution."
"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."
"The UI for this solution needs to be improved."
"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."
"VNX used to have some features that Unity still doesn't have. From that perspective, the progress is not that advanced."
"Thick provisioning of LUNs."
"Its replication technology could be better."
"The price of this product can be more cost-effective."
"They can certainly improve in terms of monitoring."
"The pricing is a bit higher than expected."
"We have only used this solution for less than one year so I don't have any improvements suggestions yet."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"Pricing could be better in comparison to other solutions."
"The file functionality could be better."
"There's always an opportunity for new feature functionality."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"Pure Storage's logs could provide more visibility to the end-user. The logging algorithms are different from those of other vendors. For example, Cisco's logs provide extensive troubleshooting data, whereas Pure Storage logs offer limited information. We have to contact support to get more information."
 

Pricing and Cost Advice

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."
"With VMware, we pay $300,000 annually."
"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."
"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."
"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."
"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."
"Our licensing fees are $500,000+ USD."
"As far as the licensing costs, everything is included in the license."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"The price is very reasonable."
"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"It is priced at around or under $50,000."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud. They have to protect their market by giving commercial or financial incentives."
"This solution offers great pricing."
"The solution could be cheaper."
"There is an annual or perpetual license required for this solution."
"The pricing of Pure Storage FlashArray is reasonable."
"We feel that the pricing is fair and the licensing process was easy for both."
"There are no licensing fees aside from the support."
"It is a cheaper solution."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
