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.

Quotes from Members

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

Pros

"Now they are trying to add more and more applications because they're getting better performance and stability."
"When we needed to replace the other arrays, we went straight to Pure and life-cycled them into Pure in every segment we have."
"All updates, upgrades, and hardware work are all performed on-line with no impact."
"We have seen savings in our storage. The speed of deployment has gone from several days to a few minutes. This product has reduced that time into minutes, simplifying storage for us."
"We are very happy with the data deduplication and compression ratio that we have on the platform."
"The solution offers amazing performance."
"The Direct FlashArray stands out as one of the best features in the market. The Pure1 storage management lets us see the details about utilization and everything else for all 40 storage boxes in one place."
"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"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."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The solution is very easy to troubleshoot, it doesn't take long to deploy, normally comes with a three-year warranty, and has the most features if you compare it to other models."
"The solution is very easy to set up."
"Out of all the solutions we've looked at, AFF is the best fit for our business requirements so far."
"It has improved our organization with efficiencies for our developers and similar items; some of the work and the way they do it, and it has actually improved their speeds quite significantly."
"We are definitely more likely to consider NetApp for mission critical storage systems based on our experience of AFF because of the support."
"Based on our experience with AFF, we are definitely more likely to consider NetApp for mission critical storage systems in the future because it's the same quality and the same value for money as we have always come to expect from them."
"Just the fact that it's been rock solid; we haven't had to sit there and baby it, fixing things, tweaking and tuning it – it just works."
"Because of all the inline deduplication and the integration with SnapManager, it allows us to set the storage and forget it with the Exchange team."
"It scales well, probably more so than the FAS. Because of the storage density with the SSDs, we can't buy enough SSDs to max one out."
"Lower latency means faster end products."
 

Cons

"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"In the next release, I would like to see file-level encryption."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."
"The price of this solution could be improved."
"I would like to migrate to the cloud in the future and know how that would actually work with this product."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"A three wave application or multi wave application synchronization would be an improvement."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"There could be a snapshot feature in the solution."
"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."
"Improvements can be made to the product's performance."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"That's what we run into a lot. Our datacenters have a need for more flexible cabling and NetApp has very strict guidelines on what kind of cables you use."
"NetApp should offer more training so everyone can learn about the products."
"NetApp is a little more on the expensive side, so it'd just have to fit whatever that they're trying to do, whatever their company is."
"The price needs to come down. Also, it has a learning curve and I needed to learn a lot to do the installation."
"Maybe the reporting tools, the performance reporting tools."
"Something I've talked to NetApp about in the past is going more to a node-based architecture, like the hyper-converged solutions that we are doing nowadays. Because the days of having to buy massive quantities of storage all at one time, have changed to being able to grow in smaller increments from a budgetary standpoint. This change would be great for our business. This is what my leadership would like to see in a lot of things that they purchase now. I would like to see that architecture continue to evolve in that clustered environment."
"We did encounter scalability issues, the solution is not delivering the requested performance (I/O response time for the requested IOPS)."
"They preconfigured it at the factory and that is a pain in the neck. This should stop."
 

Pricing and Cost Advice

"The pricing is reasonable."
"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."
"My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."
"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
"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."
"There are no licensing fees or other costs."
"The solution's price could be better."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The pricing is fair and low compared to other products in this category."
"The pricing for this solution is good compared to HP or Dell EMC."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"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 best thing about this solution is its price, which reduces our costs."
"With other options, you need to buy a couple of different products to achieve the same outcome."
"Look at the different options that NetApp offers. Look for a model and option which fits your needs correctly. Don't buy a low-end product for a high-end job."
"It is relatively cheap compared to other vendors."
"Once we did get into the NetApp ecosystem, we realized that the cost effectiveness was greater than we originally thought."
"You need to be careful with the licensing since it can become expensive."
"The pricing is competitive when we compare it to other products."
"Using NetApp, our total cost of ownership decreased by 17%."
"The list price of AFF is too expensive... they need to be careful with the pricing of the new NVMe disks. They are way too expensive."

NetApp vs. XtremIO
Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive…
