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.

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.

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.

Quotes from Members

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

Pros

"The cost of Pure FlashArray is a bit high compared to peers, but its sustainability and features justify the price."
"The simplicity of it. The performance is good, but the simplicity is the best thing. Storage management is quite complex, but Pure Storage is easy to manage."
"I use all the features of this solution and I find them to be easy to use and functional, such as the compression and capacity to expand."
"The most valuable features of Pure Storage FlashArray are simplicity, ease of use, and dashboard management."
"Everpure FlashArray is probably not cheap storage, but it provides great performance, scalability, and everything a customer needs."
"Overall, the best returns on investment have been operational simplicity, reliability, and reduced management overhead."
"The compression rate is one of the most valuable features of Pure Storage FlashArray. Additionally, it is all-flash storage with excellent IOPS, and hardware failures are very less."
"It simplifies building out the storage."
"It is a good storage solution, but there many other options out there with more resources."
"The stability is awesome, based off a mature product line that has been around since 1999, combining two well-known and well-proven technologies into a very solid solution."
"The most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."
"The price-performance ratio is most valuable; it is simple to use, and both the performance and interface are good."
"The performance of the solution is noteworthy."
"IBM FlashSystem is a powerful effective storage solution. Additionally, it is user-friendly, anyone can use it."
"IBM FlashSystem is flexible, quick, and has a solid design."
"All this storage infrastructure can be done underneath one IBM Storwize product and this is how it has impacted our organization."
"Good performance with a user-friendly UI."
"The product is a game-changer; IBM changed the game architecturally by moving computational resources into the flash media."
"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."
"Its ease of use, performance, and hardware compression is very useful feature."
"A key feature is that compared to storage systems that we've been familiar with over decades, IBM simply does not fail. The reason is that IBM is the only manufacturer that engineers its own flash module, and there is a key architectural difference from everything else that we have seen in the market. The difference is that the flash module has the computational capability, which allows reliability and capacity enhancements to be uploaded from the main controllers and run in each module. So, each of the flash drives becomes its own little storage system, and that is extremely effective architecture. In this field, with this type of system, IBM has made a statement. They've never had one of these modules cause an outage. So, the failure rates on these things are just in a whole different universe from what we were accustomed to."
"It is a very stable solution."
"IBM FlashSystem 9100 NVMe is a stable solution."
 

Cons

"With the introduction of Albireo technology and 81x data de-duplication reduction, Pure Storage better start looking at more effective de-duplication techniques."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"The backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release."
"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."
"It doesn’t provide enough information on performance analytics. For example, Nimble Storage has Infosight, which provides data; Pure Storage doesn’t have an equivalent."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."
"Price is about the only thing that's wrong with it."
"There is a need for a little bit more of a drill down in the GUI part."
"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."
"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."
"The main issue is the speed in terms of accessing the data."
"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"The solution is quite expensive. That's one of the downsides to using it."
"We've had some issues with stability, such as a couple of hardware failures and a couple of code bugs."
"The GUI needs some improvement. An additional function that could be helpful is reducing the time it takes to delete volumes, especially if they are compressed or deduplicated."
"The ZIO interface could be improved."
"The tool's architecture is complex. It also needs to add data utilization reports."
"Deduplication and compression should be improved."
"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."
"IBM is currently not offering volume-based encryption or compression, while other brands or IBM's competitors are doing it."
"Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex."
"The pricing should be more competitive."
"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."
 

Pricing and Cost Advice

"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"Pure Storage has not helped to reduce our HANA licensing costs."
"Pure Storage FlashArray's pricing is very competitive."
"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"The price of the solution can be a bit expensive. There is an additional fee for support."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"There is an annual or perpetual license required for this solution."
"All storage is expensive so any price improvement would help."
"The tool is cost-efficient."
"You purchase it as a bundle and the price is comparable."
"I find the pricing of the solution to be very 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..."
"I would rate the pricing of this solution a four out of five."
"They've been much more aggressive in the last five, six years than they were before that."
"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."
"My customers got the IBM FlashSystem bundle offer. It was a one-time purchase for three years of service. The price would depend on the storage size and could reach between $25,000 to $55,000."
"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 price of the FlashSystem 9100 NVMe is reasonable."
"The product has an average cost."
"The solution's price is competitive."
"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."
"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 tool's pricing is competitive."
