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

"It has benefited my organization because it has reduced time to insights."
"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."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"The solution is scalable."
"One of the best features is the support, which is excellent."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"We just started doing a bunch of automation where, if an end-user's home directory or departmental share gets filled, I can set certain things through a Unity API so that if it reaches 95 or 98 percent full, it will automatically expand. Now, instead of our getting a ticket and having to go in and do it manually, it does that for us."
"It is very stable."
"Scalability is good."
"Dell excels in service and support."
"We are happy with the way we have Dell EMC Unity XT configured."
"It has improved the utilization of our own internal resources and performance across our managed service platform, meeting our customers SLAs."
"I like the idea that it can compress and dedupe inline. That is quite a stunning feature for mid-range customers."
"The most valuable feature of Dell Unity XT is data duplication. Additionally, the management interface is simple, and is not a hassle using it. You don't need too much to learn or to be familiarized with it."
"The job of support for the storage engineers dramatically changed. We know more quickly the automation of the provisioning. We can now focus on things that bring more value to the company than just managing storage."
"I have seen a huge increase in speed and performance on our databases."
"The cost of Pure FlashArray is a bit high compared to peers, but its sustainability and features justify the price."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"The best feature is that it is easy to learn and use. We can easily do various tasks related to storage provisioning."
"Deduplication is an excellent feature. I also like the NAS and support."
"Data deduplication features make it easier to manage storage and forecast growth."
 

Cons

"Maybe the price can be reduced since the solution is very expensive."
"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."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"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."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"There is room for improvement in the pricing of the product."
"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."
"We'd like to see a cheaper version of an all-flash array in that footprint."
"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."
"VNX used to have some features that Unity still doesn't have. From that perspective, the progress is not that advanced."
"Dell Unity XT’s price needs improvement."
"Dell EMC Unity's competitor, NetApp, has a similar product. However, it has a clustering technology where you can group multiple systems together, then you can move data from one system to another seamlessly. I would like the Unity to do that."
"Improve the administrative user interface so it is easier to work with. Currently, a simple task, such as removing a host from 100 LUNS, takes a lot of time. If they could improve LUN to host model to be more like the EMC VPLEX, for example, it would be great."
"Dell could improve Unity XT by adding support for NVMe."
"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."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"It was not proactive communication."
"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."
"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."
"A three wave application or multi wave application synchronization would be an improvement."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"One requested enhancement yet to manifest is the scheduling of snapshot replications."
 

Pricing and Cost Advice

"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."
"The licensing is on a yearly basis."
"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."
"Our licensing fees are $500,000+ USD."
"With VMware, we pay $300,000 annually."
"We pay approximately $50,000 USD per year in licensing fees."
"The product is expensive."
"As far as the licensing costs, everything is included in the license."
"Obtaining a warranty is easy."
"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."
"Looking at it based on cost per gigabyte, it's certainly very effective."
"The solution’s pricing is competitive."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"Pricing is as high as it has ever been for EMC."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"The solution is very expensive."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"The best features come included without any additional cost."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"It is cheaper than NetApp."
"For us, as the customer, it reduced the price of the management."
