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

"The ease of management is one of the most valuable features of this solution. I would have also said that it's pretty fast but now our SQL servers are starting to beat it up pretty bad."
"Compared to Unity, these arrays offer significant advantages, such as NVMe technology and higher IOPS."
"All use cases for Everpure FlashArray are anything that requires a SAN should use it because it is the easiest thing on the market."
"I like its speed. It has all the features that I need."
"The solution has great efficiencies because it has scalability."
"Performance is the most valuable feature."
"What I appreciate most about Everpure FlashArray is that it performs compression and deduplication fantastically."
"The deduplication and compression rates are beyond impressive."
"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."
"Dell EMC Unity XT has good integration with VMware."
"It's easy to use, easy to manage, easy to troubleshoot, and the process support is good."
"The most valuable features of Dell Unity XT are the data compression for all of our VMs up to four times and the performance is good."
"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."
"Overall, I've had a very good experience with the solution so far."
"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."
"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."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The solution is very easy to set up."
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
"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."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"My advice to others is that this is a straightforward, detailed documented, and supported solution."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
 

Cons

"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"The integration capabilities could be improved."
"The solution could improve by having a multi-tenant feature."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters."
"The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"If they could make it cheaper, that would be something."
"There is not a great need for improvement, but better pricing could be beneficial."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"It is missing some features, like deduplication."
"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products."
"I would like them to continue to build on the solution and expand on the functionality, like replication."
"One thing they could do is lower the price point."
"They should have more wizards for customers so they can do more of the self-service types of functions, in terms of upgrades and patching, although it's pretty easy right now."
"We do a lot of VMware. It only integrates with VMware in one way, which is virtual volumes."
"We cannot connect directly with Dell due to sanctions."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"The features are limited."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"The solution could be more scalable, although it suits our present needs."
"There could be a snapshot feature in the solution."
"Its performance could be faster."
 

Pricing and Cost Advice

"We have seen a reduction in total cost of ownership (TCO)."
"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
"The price was more favorable than Dell EMC."
"It is a cheaper solution."
"The price, in general, is around $100,000, however, I know it costs more."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"For us, as the customer, it reduced the price of the management."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"The price is very reasonable."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"The solution is very expensive."
"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."
"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."
"Go with the virtual appliance versus the hardware."
"Looking at it based on cost per gigabyte, it's certainly very effective."
"The solution should be cheaper."
"The pricing is fair and low compared to other products in this category."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"We have a five-year contract for providing support."
"The best thing about this solution is its price, which reduces our costs."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"It is an expensive solution."
"The solution's price could be better."
"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."
