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.

High-speed data processing has improved billing cycles but performance headroom still needs growth
In terms of improvement regarding IBM FlashSystem 9100 NVMe, I can compare with other competitors, especially regarding solution architecture. Data resiliency can be a concern because IBM can reach up to only four controllers, while others like Dell EMC can support up to eight controllers with better resiliency without service staff. Additionally, the SBC one benchmark is a storage performance console that stresses different storage solutions like Dell EMC and NetApp. It generates metrics of IOPS and latency, showing that the competition can have two million IOPS, significantly outperforming IBM's capabilities. As for the capability of scaling, we can see the limitations in reaching such high-performance levels.

Reliable flash storage has delivered strong data reduction and secured sensitive information
There is still some room for improvement when it comes to scalability, mainly in the interoperability and integration aspects. Every storage vendor has certain limitations, and this is not limited to NetApp; it applies to everyone in the industry. I do not see any other significant areas for improvement with NetApp AFF C-Series at this time. NetApp is working on their roadmap, which is solid, and they are developing certain features that are yet to be released.

Quotes from Members

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

Pros

"This was our first all-flash storage enclosure, so we saw huge boost in performance for all of our servers."
"My advice to people who want to implement Pure Storage FlashArray is that it's a good NVMe solution, has a lower response time, and also good for entry-level storage purposes, e.g. small offices, small to medium-sized business, etc."
"I am very satisfied with this solution and I would recommend it to others."
"The most valuable feature of this solution is the support."
"It reduces space and the polar consumption. It also accelerates the application."
"With Pure Storage FlashArray we have been able to deploy several thousand VDI servers, virtual machines, very quickly and efficiently."
"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."
"We have looked at all of the platforms, and to see what Pure was able to do within a PoC environment meant that we never turned back our PoC environment."
"You get value for money, because the product is good in terms of control failure."
"IBM FlashSystem is an excellent product."
"The storage serves the virtual environment. Most of our applications run in the virtual environment, and it serves nearly 30% of the bank's capacity."
"It's easy to use, has good stability, and many features."
"The high performance and high availability improved our overall processes."
"It is a very stable solution."
"Good performance with a user-friendly UI."
"The FlashCore modules support more value to the architecture due to their unique characteristics."
"NetApp offers a cost-effective solution with very robust hardware."
"NetApp AFF C-Series is a good product for entry-level flash storage, the system is competitive in terms of pricing, and the value proposition is strong."
 

Cons

"The integration capabilities could be improved."
"Improved reporting on the deduplication and compression functionality would be beneficial."
"I would rate this a seven out of ten because it's a good performance storage, but the price is a little bit high."
"For large storage needs, it is expensive."
"I think replication is one area that still needs improvement."
"The price of this solution is high and should be lowered."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"A three wave application or multi wave application synchronization would be an improvement."
"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."
"The pricing should be more competitive."
"The storage system itself should have built-in capabilities for different ransomware attacks."
"Other vendors have included a block and file system. IBM doesn't include a file system."
"The solution's compression feature could be better."
"Other vendors have included a block and file system. IBM doesn't include a file system. And yet, it's very necessary for all organizations' networks to have file systems. We have other systems for the file system, however, ideally, we would like to have one system with these features."
"I would like to see IBM products become more affordable because they can be quite expensive, which limits their accessibility to a broader customer base."
"IBM's support is not good. I experienced a big problem where I opened the console IBM Storage and would see that something was broken. I called the call centers, and I said, "I have a problem. My drive is not working." They want me to give them the serial number, I gave it to them and they told me "I cannot find your product. Your product is not here.""
"There is still some room for improvement when it comes to scalability, mainly in the interoperability and integration aspects."
"We faced one bug that impacted our NetApp last month, and it took some time to identify the underlying issue."
 

Pricing and Cost Advice

"It's expensive, but you get what you pay for."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"It is light years beyond anything else with the same price point."
"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."
"It could always be lower, but it's okay."
"The solution's price is competitive."
"The price of IBM FlashSystem 9100 NVMele can be considered affordable when taking into account the operating system that is required for it to function properly. This operating system, which is licensed by IBM, may carry a higher cost, but it is worth the investment for larger corporate entities, such as insurance companies, Fortune Five companies, and banks, who make up a significant portion of their target market. The FlashSystems are designed for larger corporations and multinational enterprises, and may not be the most cost-effective solution for smaller businesses."
"The solution is priced well."
"Compared to its competitors, IBM's offering is the most cost-effective."
"It's a lot less costly than cloud storage. People get surprised by the cost of cloud storage, which is extremely expensive and four or five times the cost of storage on-premises. People don't realize what they're spending on storage until they start getting bills from Amazon, Microsoft, and others. This is a good way to reduce your cloud storage expenses."
"The tool's pricing is competitive."
"The price of the FlashSystem 9100 NVMe is reasonable."
"Compared to other solutions, the cost of IBM FlashSystem 9100 NVMe is reasonable, with a one-time payment of around $70,000. However, additional support is available for $25,000 for three years. The overall maintenance cost is steep."
