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 high performance and dependable support for fast storage needs
The most valuable feature of IBM FlashSystem is its robust back code. 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

"With this program, all of our applications are able to perform faster and this enables us to provide faster platforms and services to our customers and employees."
"The seamless integration into the public cloud has improved my organization."
"The most valuable feature of the FlashArray is Pure One, which provides a comprehensive overview of our entire storage environment."
"Technical support has been amazing."
"Access speed and power consumption are most valuable."
"The biggest return on investment for us is not having to do a swap out of the arrays every five years."
"It has good stability for our company."
"They are quite responsive and our local team was pretty good."
"It has cut batch job runtime in half, so we're seeing performance improvement throughout the organization."
"Data Compression: Up to 80% space reduction in the database"
"The initial setup is straightforward."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"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."
"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."
"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."
"We are a 100% satisfied with the stability of the solution."
"It is very, very stable, and we have never had issues."
"The installation and service was very good."
"We previously used Dell EMC and switched to this solution because the support, product and performance are of a higher standard."
"The most valuable features are performance and reliability; there are many functions, so the whole product is good."
"The most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."
"It was quite easy to migrate from EMC storage because everything is virtualized."
"User friendly interface Robust hardware Good support"
 

Cons

"I would like to see support for NVMe, end-to-end."
"It was a little costly."
"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."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"If I need to change or troubleshoot the dashboard, I cannot do it without calling support. If I want to move something critical, I cannot do it by myself. The dashboard blocks me from changing those critical things."
"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."
"The scalability of the solution is extremely costly."
"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."
"In future releases, I look forward to more AI features."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"The array level RAID does not seem available."
"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."
"This is an expensive product and if the price were reduced it would be better."
"The problem is that if the buffer is not configured correctly this increases the latency because of this delay and the retransmit."
"At our current code level, when I extend any volume that is using Metro Mirror, I have to remove the Metro Mirror relationship."
"I have used support and it needs improvement."
"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."
"IBM could do more marketing and improve brand awareness. I had never heard of this product until a colleague told me about it. FlashSystem could add a few features, but it would probably increase the price. For example, Pure Storage offers instant snapshotting and partitioning. That would be nice to have, but I think the cost would go up."
 

Pricing and Cost Advice

"The pricing is very attractive and it delivers performance for the money."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."

"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."
"We have seen a reduction in TCO."
"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."
"We have no issues with the price as it is very competitive."
"Its price is very good."
"The pricing is competitive in our country."
"Overall the price of the solution is expensive and this includes the license."
"This is an expensive product and if the price were reduced it would be better."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"The price of IBM FlashSystem is reasonable."
"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..."
