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.

Flexibility and reliability have supported seamless data growth
I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.

OpEx storage model has simplified SLAs, capacity planning, and cyber‑resilient recovery
The most valuable features in Pure Storage Evergreen One are the SLAs, which are tied to the kind of services that we are going to run. These SLAs govern the consumption and the reporting as well. I find it more attractive when we are tied to a specific SLA, and the VRA is providing the services within that agreed SLA, then there is no requirement for a complete capacity assessment. The entire capacity review, assessment, and recommendations come as part of Pure Storage Evergreen One solution. Pure Storage Evergreen One has a list of services which will provide the services, including cyber resilience. First, they have complete capacity management which is done by them and which will also provide us a heads up on how we are consuming the services and where these services can be improved. Second, it will also provide us some of the key attributes, such as we can take the snapshots and LUN snapshots, which will provide a cyber-resilient copy where data can be secured in case of a cyber attack. We have an option to basically recover the earliest. Third, because of this feature and because of Pure Storage Evergreen One, I am talking about the Evergreen aspect. Because of Evergreen, we also have an option to upgrade the controllers based on the SLAs. If the agreed SLAs are not meeting the requirement, we have a provision to upgrade the controllers and so on. This is giving a good feature for us to evaluate and provide a valuable proposition to the customer who wants to use Pure Storage as a Pure OpEx model.

Quotes from Members

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

Pros

"Its ease of use is a very big thing for our customers; it's easy to set up and easy to maintain, and the support is automated, which is very good."
"The deduplication and compression meet all of our system requirements."
"The most valuable feature of the FlashArray is Pure One, which provides a comprehensive overview of our entire storage environment."
"Pure Storage has been the go-to storage array for me; it's a lot smaller, easier to set up, faster to upgrade, more reliable, and the performance is very stable."
"The tool has reduced our power consumption."
"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."
"Redundancy and the fault tolerance of the platform are the most impressive."
"The most valuable feature is how it simplifies the management of the SAN."
"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."
"The solution in general has allowed us to move off of multiple Windows boxes where they had huge data stores, and we migrated it to the Isilon, making it easier and more cost-effective with just one point of contact."
"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."
"My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry."
"Dell PowerScale (Isilon) is a platform that is very easy for teams to work with."
"The flexibility and the user-friendly interface are the most valuable features."
"The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."
"The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed, which benefit my company by providing less downtime and less overhead."
"We have snapshots. We put snapshots on disks, and we can save information. In the case of ransomware, everything is in the snapshot. We have a snapshot lock on it, so it's safe."
"The most valuable features in Pure Storage Evergreen One are the SLAs, which are tied to the kind of services that we are going to run, and these SLAs govern the consumption and the reporting as well."
"The speed of the product is quite a bit better in performance than the previous peer environment we were running on, and it seems to have a better feature set."
"Pure Storage has the highest Net Promoter Score in the market."
"The Evergreen program is excellent, and the pricing is quite reasonable. My friends who work there are doing very well and consistently achieving strong results. Like any company, they experience occasional downturns but perform impressively overall."
"The speed of the product is quite a bit better in performance than the previous environment we were running on, and it seems to have a better feature set."
 

Cons

"The product could improve by providing the capability to support NAS storage – CIFS and NFS."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."
"Pure Storage had operational challenges between 2016 to 2018, impacting perceived reliability."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"The technical support is okay, but could be improved."
"They could improve implementation, as we had to rack and stack it ourselves."
"I have experienced a RAM failure in some of the nodes of Dell PowerScale (Isilon), and that required hardware replacement."
"The portal is really complicated to figure out features and functions, and it could be easier to navigate."
"Beyond containerized storage support and software updating, I have had very bad experiences with Dell PowerScale (Isilon) because they present more issues than other storage options, even when compared with NetApp."
"Technical support could be improved. Whenever we have a hiccup, we'd like to get it fixed maybe quicker."
"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."
"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."
"The UID mapping and how to configure mapping-related things is a struggle."
"To me, I think it's a little expensive. Then again, you get what you pay for."
"I'm not sure if any improvements are needed."
"Many customers report that the starting price is quite high. However, the overall total cost of ownership can be reduced over time due to features like the Evergreen architecture, which allows savings through less management and environmental benefits."
"I would love to explore more options on what Pure Storage Evergreen One can offer in general, mostly from the cybersecurity perspective and air gap."
"It would be nice to have support in Swedish."
"The only potential drawback is that Pure Storage might be overkill if you don't need microsecond response times."
 

Pricing and Cost Advice

"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
"We purchased a license to use this solution and we pay for the storage ourselves."
"FlashArray is expensive, but the quality justifies the price."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"There is an annual or perpetual license required for this solution."
"I would rate it a seven out of ten for pricing. It could be improved."
"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"The solution is expensive; it is not the cheapest solution out there. If you look at it from a total cost of ownership perspective, then it is a very compelling solution. However, if you're looking at just dollar per terabyte and not looking at the big picture, then you could be distracted by the price. It is not an amazing price, but it's pretty good. It is also very good when you consider the total cost of ownership and ease of management."
"The pricing is expensive, but I think it's a fair value because it does manage itself. It definitely is much simpler than any of the other scale-out storage platforms that we've looked at in the past."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"Pricing for this solution is reasonable."
"The only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."
"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."
"The price of the solution is high."
"The pricing is very good."
