Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

Ease of implementation and robust performance enhance multi-OEM support experience
We are limited only to hardware replacement, not administration tasks. We work on AMC products through Annual Maintenance Contracts. We provide support up to the 680 model. The XT680F is a newer model, and we support from 380F to 680F. The FlashSystem 8000 series is all-flash, and there is also a 5000 series flash model. We can compare IBM DS series, including the 8000 series for recommendations. For NetApp, we can recommend the FAS 8000 series.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Their support system has insight into errors on our SAN fabric that we can't see. They've brought attention to and raised awareness for us about things that we couldn't see, when we were experiencing problems."
"Once it's set up, it just runs on its own and only requires the occasional checkup."
"Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."
"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."
"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."
"I never have to worry about its performance impacting the firm."
"The solution is very reliable."
"From an investment standpoint, the support staff I require for it is greatly reduced, so I don't have the in-depth requirements that I had on other products."
"The first time we got a Unity was last year, we started deploying some of our file system data into it, and we have been seeing a significant improvement, not just in the way that we take Snaps, but with the recoveries as well."
"The high availability of Dell EMC Unity XT has been the most important feature."
"I can't say enough about the Flex on Demand because it gives you the agility you need."
"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."
"User friendly interface"
"It is the performance combined with the Gig-per-dollar value; that combination is superior to other storage options."
"This product is perfect for small, and mid-range customers who need to pay less, but still get enterprise-level capabilities."
"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
"The solution is very easy to set up."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
 

Cons

"The price should be lower."
"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says it is completely full."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"The integration capabilities could be improved."
"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."
"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."
"We would like to see the concept of Storage Groups brought back to this product line."
"We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions."
"The VNX reporting is much more granular, versus the Unity reporting."
"Technical support has gotten worse since the merger, for example, response time to SR creation."
"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."
"The one thing that we would look at would be if they were to expand the file level features, just to give us a balance or a tier between it and Isilon options out there, for unstructured data."
"This solution would be improved with the addition of flexible raid volumes."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"The product could support advanced software integrations."
"Improvements can be made to the product's performance."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"The solution could be more scalable, although it suits our present needs."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
"Scalability on rack-mount servers is not as good as with Blade servers."
 

Pricing and Cost Advice

"All storage is expensive so any price improvement would help."
"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."
"The price is very reasonable when compared to other solutions."
"We do not incur additional costs beyond the licensing fee."
"I would prefer that they lower their pricing."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"From a pricing perspective, this solution is comparable to others on the market."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"Go with the virtual appliance versus the hardware."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"The solution should be cheaper."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"The product’s pricing should be improved."
"We have a five-year contract for providing support."
"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."
"The pricing for this solution is good compared to HP or Dell EMC."
