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

"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"After switching to Everpure FlashArray, we saw significant results, as whatever hardware we used before is now compressed to 80%, maximizing space utilization in a single system."
"Pure Storage has been the go-to storage array for me; it's a lot smaller, easier to set up, faster to upgrade, more reliable, and the performance is very stable."
"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."
"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"The speed is the most valuable feature, along with the ease of getting it connected. We were able to get it online in less than a day."
"I have never experienced an outage with the product or had any support that was below excellent."
"One feature that's particularly valuable for our finance customers is Pure Storage's safe mode. It protects against ransomware attacks by taking snapshots. Our customers were very impressed with this capability. The data reduction is also impressive compared to other providers."
"We use IntelliFlash products for larger environments, like Qatar Airways."
"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."
"It has cut batch job runtime in half, so we're seeing performance improvement throughout the organization."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"High performance and ease-of-management are the most valuable features."
"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 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 most valuable features are flexibility and performance."
"This solution is very scalable."
"User friendly interface Robust hardware Good support"
"It was quite easy to migrate from EMC storage because everything is virtualized."
"The pricing is reasonable."
"The most valuable features are performance and reliability; there are many functions, so the whole product is good."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"The speed of the unit is its best feature. It performs very well."
 

Cons

"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."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"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."
"In the next release I would like to see integration into other third-party player providers like Google."
"The scalability of the solution is extremely costly."
"During heavy load situations with 100K IOPS on one specific port, it requires more granularity level for distribution."
"Pricing could be better in comparison to other solutions."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"Snapshots are not as easy to access as on a NetApp device."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"I would say it's somewhat scalable, maybe not so much as some of the competition, but we don't really care."
"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."
"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."
"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"The product could be cheaper."
"There are some issues on a firmware level."
"Our model does not support compression or deduplication."
"IBM FlashSystems is lagging in optimizing storage technologies, which can be improved."
"The cost of the solution is too high. They should work to make it lower."
"There is a need for more help with the commands because, from version to version, they change; so what I used to use back in the different version, I can't use now."
"The generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."
"It should increase sociability with respect to number of disk shelves and capacity."
 

Pricing and Cost Advice

"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"It's a good price point and it's a solid product for the price."
"The best features come included without any additional cost."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"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 IBM FlashSystem is reasonable."
"Its price is very good."
"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."
"We have no issues with the price as it is very competitive."
"The solution has good pricing, but it is not cheaper."
"The pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from."
"The price depends of the technology that our customers need. The price can come at a lower cost but this may increase as storage is added."
"Overall the price of the solution is expensive and this includes the license."
