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

"This improves our organization because we can just set it up and we forget about it, everything works, and we do not need to worry about storage or bandwidth issues."
"You can get your storage access within two minutes, which is great, because it is a lot quicker for our team to get the servers up and running."
"Cuts VM deployment down to seconds and cuts latency under MS with amazing performance and very stable operation with no worries about how much it can handle."
"My favorite feature about Pure Storage FlashArray is definitely the simplicity; in one word, it's simple to install, simple to upgrade, simple to maintain, and simple to manage."
"When you put all of the features in a box, leverage them and migrate your application to one of these arrays, it will give you a lot of benefits."
"Very efficient storage"
"It is always out of the box, and ready to use."
"Pure Storage FlashArray offers numerous valuable features, such as low latency and high throughput."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"Data Compression: Up to 80% space reduction in the database"
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"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."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks Cheaper than pure solid state without needing to actively manage where the data is located."
"Tegile All-Flash Storage Arrays deliver maximum performance, high density, compelling economics and it is ideal for latency-sensitive, business-critical workloads such as online transaction processing, real-time analytics, decision support, and data warehousing."
"After five years, the cost decreases over 30% and the performance increases over 50%."
"High performance and ease-of-management are the most valuable features."
"The most valuable feature of this solution is the price to performance ratio."
"This is a stable product that we can use for DR in production."
"The majority of our customers find this solution simple to use."
"There are plenty of features available in this solution."
"Huawei OceanStor Dorado is equipped with powerful controllers"
"Overall, it works fine. It's really easy to use."
"Technical support is very responsive."
"The price of the solution is competitive compared to others, such as Dell EMC and Hitachi."
 

Cons

"On the technical side, the way that the array performs cleanup and garbage collection sometimes pushes it close to 100 percent utilization, causing some stress."
"Pure Storage's logs could provide more visibility to the end-user. The logging algorithms are different from those of other vendors. For example, Cisco's logs provide extensive troubleshooting data, whereas Pure Storage logs offer limited information. We have to contact support to get more information."
"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."
"In some cases, we get into very in-depth conversations around movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"They should work on their upgrades, they're not smooth."
"There is not a great need for improvement, but better pricing could be beneficial."
"Improved reporting on the deduplication and compression functionality would be beneficial."
"In terms of improvement, Everpure FlashArray could have more attractive UI/UX design compared to other solutions."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"In future releases, I look forward to more AI features."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"We had just one small stability problem with power flapping and it did not start up again automatically."
"It's somewhat scalable, but maybe not so much as some of the competition."
"The monitoring matrix and its dashboard need work."
"Difficult integration with third parties."
"Huawei OceanStor Dorado's biggest weakness is its lack of cloud integration."
"There could be local support services available for the platform. Additionally, they should provide a bundled license, including all protection and encryption rules."
"With Huawei Durado we have some issues regarding the connectivity with the AIX system; it should have easy connectivity with AIX, however, I've found that with AIX it has some issues and due to this we need to remove the exact fiber card sometimes and then plug it in again so that it can connect with the AIX systems."
"There are some limitations to this product because they do not have unified storage."
"It's not easy to receive an upgrade license of Huawei OceanStor Dorado. It's easy to buy OceanStor with several features, but when you want to add on features later it's not easy."
"From the customer's point of view, Huawei OceanStor Dorado is expensive."
"For future releases, it would be beneficial for OceanStor Dorado to integrate advanced analytics and AI-driven functionalities for predictive maintenance and performance optimization."
 

Pricing and Cost Advice

"The cost has room for improvement."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"The pricing is reasonable."
"Cost-wise, it's been very effective."
"We have seen a reduction in total cost of ownership."
"The solution is expensive."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."
"I think we pay around 100 grand per year for three arrays or four arrays."
"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
"The price of the solution is competitive compared to others, such as Dell EMC and Hitachi. I believe the reason they are providing a discount is they want to increase their penetration into the market."
"You need to pay for the license."
"The price of the solution is reasonable. There is not a vendor that offers an All-Flash Storage Array at the price of Huawei OceanStor Dorado. The other solutions are approximately 50% higher."
"There are lots of features included with this solution and some of them require additional licensing, such as creating high availability storage using a cluster."
"The pricing is one thing that works for them. I think their pricing is more competitively affordable than these top competitors."
"This product is not too expensive, and the price is competitive on the market."
"The solution's licensing structure needs improvement."
"We usually recommend our customers choose advanced licensing and enterprise companies are more inclined to choose this solution because it is more cost-effective than competitors."
