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.

Offers flexibility and top-notch technology
You can go to bed peacefully if you have a NetApp. If you have NetApp within your data center, you get to know about power failure if you are using it. Your NetApp will still come alive. Even if it does not come alive, I can say that it is not like other tools when it comes to dealing with power failure. The tool is affordable, and the technology is top-notch. It is the only technology that has software for what we call inline compression and deduplication. All the products under NetApp are aiming to use AI. I know that you can achieve whatever you want to do with NetApp EF-Series All Flash Arrays. I rate the tool a nine out of ten.

Quotes from Members

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

Pros

"We tested our VDI environment on this array and it performed flawlessly and boosted the user experience."
"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."
"The product has not gone down in a year, so I would say that it is stable, and we haven't seen any high spikes in read/write latency."
"There was a dramatic improvement in operating costs just as a result of the environmentals and space, let alone the cost of the unit itself."
"Data reduction and compression. Sub millisecond latency."
"It simplifies storage."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"We have integrated the solution with VMware, and the process was seamless."
"Data Compression: Up to 80% space reduction in the database"
"We use IntelliFlash products for larger environments, like Qatar Airways."
"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."
"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."
"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%."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"High performance and ease-of-management are the most valuable features."
"The solution is very good; it offers very good performance and very good data services to customers."
"The main advantage of this solution is performance."
"The speed is the most valuable feature."
"Our batch processing time went down from 14 hours to seven hours with this solution."
"I would recommend it. It is very stable, fast, and offers good support."
"The most valuable feature of this solution is its speed."
"Rapid deployment, easy integration management and cloning of areas."
"You can't beat it for the price."
 

Cons

"For large storage needs, it is expensive."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"Awareness about Pure Storage needs to increase. Currently, people mostly think of Dell and NetApp when it comes to storage."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"We have not had a good experience with the IBM device."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"We had one instance with an eight-hour outage in our primary data center because the upgrade to the controller failed, and the controller redundancy didn't work."
"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"The monitoring matrix and its dashboard need work."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"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 the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."
"Snapshots are not as easy to access as on a NetApp device."
"This solution does not have any compression or deduplication."
"The solution should really build out a more hyper-converged product."
"There could be an improvement when it comes to SLA support, it could be faster."
"The solution's technical support is not as good as it is supposed to be since you have to push them to get support."
"The support of the product is an area with certain shortcomings where improvements are required."
"It needs a better management tool."
"Better support technicians for CAPP."
"When it's a software-related issue, it is difficult to find an engineer that can help you."
 

Pricing and Cost Advice

"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."
"Our costs are around $100,000."
"It's a good price point and it's a solid product for the price."
"The price of the solution is not expensive."
"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."
"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 should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"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."
"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."
"They provide licenses upon purchase, so there's no need for additional licenses. Regarding additional expenses apart from the standard licensing fees, such as for support or maintenance, there aren't any. Updates take around twenty to thirty minutes, including rebooting the systems, and we haven't faced any problems with the NetApp EF-Series All Flash Arrays. We utilize various other storages like Fujitsu, IBM, and Dalian SIP, but the NetApp EF-Series stands out as we've had no issues throughout the entire year of usage."
"The price point for EF is considerably lower than the alternatives."
"This solution is not available to many users because the cost is very expensive."
"The pricing is comparable with other competitors and similar in mid-range solutions, and for high range solutions, it would depend on our requirements or needs."
"The pricing of the solution is expensive, considering the initial investment required...At the end of the product's life cycle, it could get cheaper, but the initial investment in NetApp makes it one of the most expensive solutions."
"Price-wise, NetApp EF-Series All Flash Arrays is costlier than Dell. You have to buy a lot of licenses separately."
"NetApp EF-Series All Flash Arrays is an expensive product."
"Adding more capacity will increase the cost."
