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.

When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.

Quotes from Members

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

Pros

"Whoever is using Pure Storage is happy with it, including the latency and everything, and we have not received any complaints related to Pure Storage throughout the four years I have worked here, which is really great."
"Pure Storage FlashArray provides immediate benefits to our customers with its easy setup process, allowing for instant use and rapid realization of advantages."
"From the performance that I've seen, the simplicity of how to use it, the responsiveness, and customer experience, it is one of the best companies that I have worked with so far."
"I like its speed. It has all the features that I need."
"Technical support is very good."
"The dashboard is nice. It is easy to manage compared to other storage solutions such as Dell EMC."
"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."
"The speed is one of the most valuable features of Pure Storage FlashArray."
"Ease of Use: Someone can learn it in only few hours Performance: Easy Tier is doing miracles Data Compression: Up to 80% space reduction in the database"
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"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."
"With so much technological advancement and more coming, the world is their oyster."
"High performance and ease-of-management are the most valuable features."
"We use IntelliFlash products for larger environments, like Qatar Airways."
"The initial setup is straightforward."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"This storage has incredible performance, the I/O is awesome."
"IBM FlashSystem is fast and reliable."
"IBM FlashSystem provides a very good value."
"It's very easy to manage."
"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."
"FlashSystem offers proven technology in a compact package."
"The most valuable features in IBM FlashSystem are IOPS, performance, duplication, and compression."
"One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless."
 

Cons

"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"In some cases, we get into very in-depth conversations around the movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"They should work on their upgrades, they're not smooth."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"When creating a support case, visibility should be extended to others involved in assisting."
"I wish they could add more of a monitor on the machine itself so you don't have to rely on a KVM or something to look at the display, such as an onboard diagnostic display."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"The monitoring matrix and its dashboard need work."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"In future releases, I look forward to more AI features."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"There is a need for a little bit more of a drill down in the GUI part."
"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."
"The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."
"We have not had a good experience with this platform."
"The solution is quite expensive. That's one of the downsides to using it."
"When you provision a datastore auto-format takes a long time"
"It should increase sociability with respect to number of disk shelves and capacity."
"The security features can be improved such that the encryption does not affect performance in any way."
 

Pricing and Cost Advice

"There are no licensing fees or other costs."
"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."
"Its price is almost double than any other flash storage solution."
"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."
"The price was more favorable than Dell EMC."
"I would rate it a seven out of ten for pricing. It could be improved."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"Pure Storage FlashArray's pricing is very competitive."
"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
"I think we pay around 100 grand per year for three arrays or four arrays."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"The cost of the IBM FlashSystem is lower than the HPE solution."
"Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions."
"You purchase it as a bundle and the price is comparable."
"The tool is cost-efficient."
"We have no issues with the price as it is very competitive."
"The total storage capacity vs price is still quite high for the IBM Flash Array."
"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."
