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

"One of the best features is the support, which is excellent."
"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."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The solution is very straightforward to set up."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The most valuable feature of this solution is its ease of use."
"The high availability of the product is the most valuable feature."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."
"It is completely reliable. The plugins for it are quite mature. I don't really have any issues with the interactions with vSphere, they all work as intended."
"The replication is big for us. We use file services on Unity and it has a really nice file services interface. It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy."
"Dell Unity XT is a unified box, and it is integrated with VVOL, our software-defined storage."
"The high availability of Dell EMC Unity XT has been the most important feature."
"It’s helped with the overall stability of our VMware environment."
"It has improved the utilization of our own internal resources and performance across our managed service platform, meeting our customers SLAs."
"The multiprotocol support. It's supporting NFS, fiber channel, CIFS, and these kinds of things. The multiprotocol is very attractive."
"The availability and ease of use are the big features."
"They are quite responsive and our local team was pretty good."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"The most important feature of any storage array is its reliability, measured by its uptime."
"We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"They have a very good support system, and the GUI is also very intuitive."
"Technical support is excellent. I've had very good responses from technical support. We had a couple of cases where we needed support. Some of the communications were purely over email and some has been an actual call to the service desk."
"This solution has helped my organization by cutting down on provisioning time. I used to have to provision a VM and it would take ten minutes. Now, it takes thirty seconds."
 

Cons

"In the future, I would like to see integration with enterprise backup systems."
"The UI for this solution needs to be improved."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"There are some challenges with data encryption and reduction."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"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."
"The tool's portfolio is minimal. It is expensive."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"The uses of tools to communicate with EMC directly. With EMC, I am not able to connect and resolve issues without assistance, so they can't do unattended maintenance on devices, which would be a massive benefit if they could."
"There is an ESRS problem that we're facing where, for some reason, the other Unity has not been able to register to EMC. The support information is not upgrading and nobody can tell me what is wrong with it. It's a minor issue, the ESRS is still working, but it is something that is very confusing and nobody seems to know what to do about it."
"Dell EMC Unity is not sexy. It doesn't have all the flash and pizzazz of some of the other storage vendors."
"It could always use native replication. Then I could get rid of RecoverPoint."
"In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside."
"I rate the scalability of Dell Unity XT a nine out of ten."
"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup. This would help us minimize our IT cost in terms of the backup procedures."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"Improved reporting on the deduplication and compression functionality would be beneficial."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."
"Storage. There could be better storage."
"They should work on their upgrades, they're not smooth."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
 

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."
"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."
"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."
"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."
"The support cost per array is about $20,000 a year for 24/7 support."
"Our licensing fees are $500,000+ USD."
"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."
"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."
"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."
"We have to apply for a license for each system."
"The pricing of Dell Unity XT is good."
"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."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"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."
"Pricing is moderate. It is neither cheap nor expensive."
"Our costs are around $100,000."
"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."
"Pure Storage has not helped us to reduce our licensing costs."
"It could always be lower, but it's okay."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."
