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 most valuable feature of this solution is its ease of use."
"What I really like about this program, is that it is easy to use and easy to configurate."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."
"The most valuable features of this solution are its ease of use and performance."
"The latency is good."
"The database workloads are pretty fast because I frequently move data from here to there."
"Overall stability is very good. It is a very stable solution."
"We can sleep at night because the support is great."
"Dell Unity XT is quite scalable and can be scaled up to the petabyte level."
"The UI itself is fantastic, and the ease of administration is far better than Unisphere or Navisphere ever were. It's very easy to manage. The fact that it has built-in APIs means our automation people can help us automate a lot of tasks, and that has been helpful. And, of course, it's really fast. Obviously, that doesn't hurt anything at all."
"I like the easy management with the new Unisphere management and the HTML5 interface."
"It is easy to manage. Managing it, I get alerts if there are any type of issues. I had a hard drive go bad, which had never caused any issues. Dell EMC contacted me, and said, "We are a shipping a new one out." My response was, "Why?" He told me that hard drive was bad. So, I went and looked, and it was. This was almost immediate. I never even knew anything had happened."
"The most valuable thing for our use case is the flexibility to have multiple-protocol support."
"It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing."
"Its main advantage over vSAN was the rebuild, the intelligence of the restoration in the event of a hardware drive failure and, of course, the all-flash solution."
"It gives us capacity planning."
"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"It has good stability for our company."
"The predictive performance analytics is a very good feature, as our system is performing better than before."
"It has improved my organization because now have lower latency, we get fewer complaints from customers, and we see a constant response time."
"I like the performance. Performance-wise, it accommodates the needs of highly-critical servers. It is reliable."
"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."
"At this point, I don't know anything that they could provide in a better way."
 

Cons

"The tool's portfolio is minimal. It is expensive."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"They could add more support for file storage and different types of storage."
"The UI for this solution needs to be improved."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"There is room for improvement in the pricing of the product."
"I would like to see replication and DR features in the next release of this solution."
"The software layer has to improve."
"The storage processors have less port expansion than previous high-end VNX arrays. Data compression is only available in all-flash pools."
"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."
"It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual."
"I rate the scalability of Dell Unity XT a nine out of ten."
"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."
"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 integrated it with vSphere but that integration was "iffy". It was okay but we had a few challenges with it."
"Thick provisioning of LUNs."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"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."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform. The idea is that they would run a basic NFS or CIF share from the controllers. FlashBlade is the powerhouse for File and Object storage, but if you don't need all that power, a lightweight file function would make FlashArrays more versatile."
"I want to improve the overall service level of the solution."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"The price of the solution can improve."
"It is a bit expensive."
 

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."
"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."
"The product is expensive."
"The licensing is on a yearly basis."
"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."
"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."
"With VMware, we pay $300,000 annually."
"Given its price, Pure is not the first option."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"We have to apply for a license for each system."
"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."
"The price is up a little bit from what we used to pay so I'm hoping that it's a little bit of a better system than the VNXe was. But I still think it's a good value. It's new, so I'm sure there's room for the pricing to drop."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."
"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."
"Most licenses for the solution are free but upgrades are available when adding additional software or storage."
"Pure Storage has not helped us to reduce our licensing costs."
"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."
"There is an annual or perpetual license required for this solution."
"Pure Storage has not helped to reduce our HANA licensing costs."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"The price of the solution is not expensive."
"The pricing of Pure Storage FlashArray is reasonable."
"Its price is almost double than any other flash storage solution."
