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

"It has been quite satisfactory in performance and scalability."
"The tool has reduced our power consumption."
"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."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"One of the features that my customers are really interested in is immutable snapshots. There are immutable snapshots to which your applications can be reverted back if you are hit by some kind of ransomware threat or malicious attack. That's kind of a key deal, and it is one of the selling points I use to point out to my customers the value and the features that Pure Storage brings to the table."
"Everpure FlashArray has positively impacted my organization by increasing our agility and the ability to run our environment at high speeds due to the flash storage."
"It makes things ten times easier."
"This improves our organization because we can just set it up and we forget about it, everything works, and we do not need to worry about storage or bandwidth issues."
"There are many valuable features of IBM FlashSystem 9100 NVMele I have found to meet my needs. Specifically, the maintenance cycle is a standout feature of this solution. The main component of the IBM FlashSystem 9100 NVMe is the maintenance of the batteries, which have a predetermined and reliable four-year life cycle. This is in stark contrast to other solutions that may use spinning disks, which can fail unexpectedly, causing unwanted downtime and maintenance. Having a predictable maintenance cycle is a significant advantage and has made this solution a preferred choice for me."
"The most valuable feature is the speed."
"IBM FlashSystem is an excellent product."
"The FlashCore modules support more value to the architecture due to their unique characteristics."
"IBM FlashSystem 9100 NVMe is easy to use and comes with good performance."
"The most valuable feature of IBM FlashSystem 9100 NVMe is the snapshot. We use it daily for all of the storage units."
"It is a high-performance product that serves our requests well."
"The most valuable features of IBM FlashSystem 9100 NVMe are its steady performance and usefulness in high-traffic environments."
"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."
"NetApp offers a cost-effective solution with very robust hardware."
 

Cons

"FlashArray could improve on the administrative side. For example, when you need to upgrade the boxes, we can't do that ourselves. We need to open a ticket with support and have them do that for us. You don't need to be on the call with them. We tell them we have a slot that we want to upgrade, and they send us an email when it's done."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"The cost of the storage needs improvement."
"The negative aspect of Everpure FlashArray is that migrations can be somewhat complicated."
"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."
"I would like to have support available in Spanish."
"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"I would like to see them develop the ability to integrate with more AWS services. There are increasingly more and more services coming out from AWS but there are also certain constraints where we can't move everything over to a cloud as well. We would like for things that are on-premise to be easily integrated with AWS."
"Other vendors have included a block and file system. IBM doesn't include a file system."
"Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex."
"There is a tool provided by IBM for repairing batteries which can only be utilized by those who have an IBM technical advisor under service contract. However, for individuals who do not have such a contract, the tool can be difficult to use and requires a zip file copy. I believe that it would be greatly beneficial if the tool were made more user-friendly and accessible for all individuals who need to repair batteries."
"IBM FlashSystem 9100 NVMe is currently at the end of its lifespan and will soon become obsolete in the markets."
"The efficacy of the GUI in IBM FlashSystem 9100 NVMe could be enhanced, and it would be beneficial to include a feature that can prevent ransomware attacks."
"The tool's architecture is complex. It also needs to add data utilization reports."
"The solution's compression needs to be improved, as it's not the best."
"I'd like to be able to connect to tape drives behind the storage device to back up the tape if need be. We have all of our storage running in all-flash, and we make a copy on tape. Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex. We want IBM to add a feature where we could install a tape into the storage so that we can connect it through a single pane of glass. We'd like to have a feature in the IBM flash storage system so that we can connect backup tape drives through the IBM storage system and we can manage the backup tape from the storage system."
"We faced one bug that impacted our NetApp last month, and it took some time to identify the underlying issue."
"There is still some room for improvement when it comes to scalability, mainly in the interoperability and integration aspects."
 

Pricing and Cost Advice

"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."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"Pure Storage FlashArray's pricing is very competitive."
"There is an annual or perpetual license required for this solution."
"Cost-wise, it's been very effective."
"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."
"Pure Storage has not helped us to reduce our licensing costs."
"Compared to its competitors, IBM's offering is the most cost-effective."
"The solution is priced well."
"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."
"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."
"The solution's price is competitive."
"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 price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."
"The tool's pricing is competitive."
