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

"I would recommend Pure Storage FlashArray to other users because, first, the speed that I get with Pure Storage FlashArray is not remotely possible with any other product at this price range, and second, the support is absolutely fantastic."

"You can even review the devices from your phone. You don't need to be connected to your company's website or VPN to access alerts and reports. While you can't manage the devices using your phone, you can review all the important details about the machine."

"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."

"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."

"The solution is stable with low vulnerabilities."

"There is no comparison performance-wise."

"It has improved the way our organization functions by improving the resilience of our infrastructure by quite a bit."

"At this point, I don't know anything that they could provide in a better way."

More Everpure FlashArray pros

"The most valuable aspects of this solution are its stability, performance, and ease of updating."

"Technical support is very good."

"It has good performance."

"It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNS. We just have to add and configure the storage in one place and it takes care of everything, which is very handy."

"It is very user-friendly to read and determine the exact problem, unlike HP where different tools and L3 team support are needed."

"The multiprotocol support. It's supporting NFS, fiber channel, CIFS, and these kinds of things. The multiprotocol is very attractive."

"The high availability of Dell EMC Unity XT has been the most important feature."

"It has compression, which allows you to store more data than you would normally under the arrays."

More Dell Unity XT pros

"The most valuable features are simplified provisioning and management, de-duplication, and built-in encryption."

"This solution had the best cost and it was easy to work with the Vendor."

Cons

"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."

"I would like to see data tiering to AWS."

"Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE."

"They should work on their upgrades, they're not smooth."

"It would be beneficial to have a health check command that can be run from the CLI to ensure that all hardware components are functioning properly rather than having to enable remote access and connect to support for a health check."

"Some of the issues are that it's probably not on a par with other large storage enterprise type products."

"The initial setup of the product is complex."

"It was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."

More Everpure FlashArray cons

"The price has room for improvement."

"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud."

"We have had a lot of issues. We've got massive issues at the moment with IBM AIX, it's not stable, we have a lot of disk errors, production crashes sometimes, and that's not good for a retailer."

"I'm not sure if it has a single pane of glass management console. That would be something we would like to see."

"It is missing some features, like deduplication."

"For the upgrade from the old system to the new system, if there was a better way to integrate them so I could easily move the data without working all those nights and weekends, that would be nice."

"It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual."

"The lack of deduplication reduces some of the competitiveness compared to other products."

More Dell Unity XT cons

"The exterior display needs to be improved."

Pricing and Cost Advice

"It's a good price point and it's a solid product for the price."

"We purchased a license to use this solution and we pay for the storage ourselves."

"For us, as the customer, it reduced the price of the management."

"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."

"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."

"You get what you pay for. It is expensive, but it really works."

"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."

"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."

More Everpure FlashArray pricing and cost advice

"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."

"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 price is very reasonable."

"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."

"Licensing is easy since all the software is included."

"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."

"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."

"We checked both HP and Dell and we determined that Dell EMC was a better option."
