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

"It simplifies building out the storage."
"The ease of use. That's what our customers love. They say it's very easy, they don't need special training, they don't need to call us or any other company or integrator to help them do their job. That's the main reason they purchase Pure."
"The performance is great."
"The scalability is good."
"My advice to people who want to implement Pure Storage FlashArray is that it's a good NVMe solution, has a lower response time, and also good for entry-level storage purposes, e.g. small offices, small to medium-sized business, etc."
"The stability and performance are the best things about the solution."
"The most valuable feature of Pure Storage FlashArray is its high stability level."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"When comparing them all in their strengths for implementation, the lifecycle of the product, and the support they provide, I would rank Dell number one, IBM second, and third would be Fujitsu."
"Pricing is relatively good compared to other vendors with the same specifications."
"One of the things that I like the most about it is how they have changed the Unisphere GUI, and how it is now HTML5. It is so easy to use. Also, the array itself is so simple, easy to set up and easy to use, but it still has that great Dell EMC technology behind it."
"The architecture is robust; it was the good, old-fashioned storage array, block array for customers, and it's reliable."
"The fact that it's hybrid is the most valuable feature. We have the SSD so we put our SharePoint on there and some of the stuff that requires a little more speed. For SharePoint, we want the pages to respond a little more quickly. And it's nice to be able to use the slower storage for stuff that we don't need as quickly, like file servers."
"For our environment just having a solid, running box is really sufficient."
"I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward."
"Purchasing; We worked with a sales rep to purchase our Unity."
"Lenovo ThinkSystem DE Series is cost-effective; there is no license, all of the features are bundled together, and you can renew the bundle with all of the features included."
"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."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
"The solution is very easy to set up."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
 

Cons

"Some of the issues are that it's probably not on a par with other large storage enterprise type products."
"The only thing is that we've had to upgrade controllers a few times because we ended up wanting to use more stuff on here."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."
"It would be beneficial to have a separate pricing point for environments with lower performance requirements or less workload."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"The product could improve by providing the capability to support NAS storage – CIFS and NFS."
"Most of our upgrades have not been as smooth as they should have been."
"For us, it was expensive, but it was of value to us. However, I wouldn't go through that again."
"The interface and configuration could improve."
"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."
"There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available."
"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."
"A customer had to buy VMX because Unity didn't have WORM."
"Ordering is easy, but the processing site and working with those companies was difficult."
"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products."
"Usually, when a part fails, we have to replace it and it takes a while."
"The solution could be more scalable, although it suits our present needs."
"Scalability on rack-mount servers is not as good as with Blade servers."
"The solution could be more scalable, although it suits our present needs."
"Improvements can be made to the product's performance."
"The product could support advanced software integrations."
"Improvements can be made to the product's performance."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
 

Pricing and Cost Advice

"Cost-wise, it's been very effective."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"It could always be lower, but it's okay."
"It's priced higher than the market."
"There are no fees for licensing. The hardware is paid for only once."
"Pure Storage has not helped to reduce our HANA licensing costs."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"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."
"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."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."
"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."
"The product’s pricing should be improved."
"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."
"The best thing about this solution is its price, which reduces our costs."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The pricing for this solution is good compared to HP or Dell EMC."
"We have a five-year contract for providing support."
"The solution's price could be better."
"The pricing is fair and low compared to other products in this category."
"It is an expensive solution."
"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."
