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.

Good customer service and support and suitable for large environments
It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Quotes from Members

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

Pros

"The most valuable feature is test performance. It helps us store large amounts of data along with providing us faster retrieval of data."
"They can provide a lot of performance, so there is not a lot of difference, but efficiency is something customers value because the compression can be up to twice of the second competitor."
"It is easy to deploy and it's all-flash, so it's very fast."
"It has been quite satisfactory in performance and scalability."
"The administration is very easy and quite minimal, the performance is very good, the installation is pretty straightforward, and technical support is good."
"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."
"We currently have four Pure Storage FlashArray boxes, and all the storage boxes are on an Evergreen subscription model where we receive the latest hardware and features without any cost in a completely non-intrusive task."
"We experience fast demos and zero downtime; we do not experience any downtime with Pure Storage, thanks to resilience with Safe Mode, integration with backup software, and everything related to cyber resilience."
"It has cut batch job runtime in half, so we're seeing performance improvement throughout the organization."
"After five years, the cost decreases over 30% and the performance increases over 50%."
"We use IntelliFlash products for larger environments, like Qatar Airways."
"High performance and ease-of-management are the most valuable features."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It performed great originally, and when it performed great, it was awesome."
"We have been able to realize storage space savings for our virtualization environment and it has reduced our electricity usage by reducing the number of disks needed for the virtual environment."
"The initial setup is straightforward."
"The platform's most valuable features are reliability, intelligence, and fast performance speed."
"The initial setup is straightforward. Deployment takes about a day."
"Huawei OceanStor Dorado is a stable solution."
"Technical support is very responsive."
"We can use Huawei OceanStor Dorado capacity storage for many different purposes."
"Has good capacity, is effective and easy to manage."
"Huawei OceanStor Dorado is equipped with powerful controllers"
"The performance is good."
 

Cons

"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"What I dislike about Everpure FlashArray is that in the replication, if it is in the pod, we cannot directly add devices to the pod without breaking the relationship."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"The price of this solution is high and should be lowered."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"In future releases, I look forward to more AI features."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"Snapshots are not as easy to access as on a NetApp device."
"The monitoring matrix and its dashboard need work."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"It's annoying that if you turn on SMB3 (as opposed to the earlier CIFS protocol), then it is not possible to access a file store using a mixture of SMB and NFS."
"The solution's price could be better."
"The product should be better aligned with the virtual environments"
"The data compression and deduplication ratio of Huawei OceanStor Dorado is not as good as other solutions, such as EMC and Pure Storage. It is important when looking at capacity effectiveness."
"The localization problem needs to be improved."
"If they implement a backup solution directly into the OceanStor then it will be a valuable feature."
"Huawei OceanStor Dorado could improve the integration, there have been some compatibility issues with some operating system functions."
"The product's current pricing model involves over 12 different licenses, which can be complex. Simplifying the process would enhance the overall user experience."
"The product could always be faster."
