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.

Enhanced speed and integration benefit hybrid environments but cost remains a concern
The Hitachi VSP E Series is all-flash storage, so it is fast. It is quite good for databases, and clients who are familiar with Hitachi prefer to use it. Clients with hybrid environments generally look for something like a single glass view, where they can integrate all their different systems and view everything on one screen or desktop.

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

"Overall, Pure Storage FlashArray has never let us down in front of customers so far."
"Pure gives us better compression, it's easier to manage, a lot less hands-on."
"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."
"Even if they weren't one of the fastest arrays in the entire industry, I would use them for their support model and ease of use."
"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."
"After moving to Pure Storage, I have noticed that our databases are considerably faster and our performance has improved by at least four times."
"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."
"It is very easy to use."
"Its user-friendly configuration and maintenance processes contribute to its reputation for being straightforward and easily manageable."
"It offers good file sharing."
"I rate Hitachi VSP series nine out of ten for a transactional workload requiring no compromise on availability and performance."
"We are using the Hitachi VSP E Series for high IOPS."
"Hitachi VSP handles large volumes of transactions with ease, and we often support customers in this direction when we have Oracle in the middle."
"The product is generally quite stable."
"The most valuable features of Hitachi VSP series include its high performance and availability."
"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."
"The features I find most valuable include its use for storage and performance."
"The FlashCore modules support more value to the architecture due to their unique characteristics."
"The product is a game-changer; IBM changed the game architecturally by moving computational resources into the flash media."
"What I like about the product are its high availability, maximum efficiency in performance, and its ability to handle a high level of I/O operations."
"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."
"It's easy to use, has good stability, and many features."
 

Cons

"It is a bit expensive."
"I would like to see data tiering to AWS."
"For scalability, I rate it a six out of ten. We reach a limit. We never reached this limit, however, the architecture allows you to go until a certain size, and after that, you have to buy another array."
"In the next release I would like to see integration into other third-party player providers like Google."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"Hitachi should work on unified storage platforms."
"The graphical user interface is somewhat outdated, lacking some of the modern features found in other solutions."
"Hitachi is quite expensive, and small to medium-sized organizations usually do not purchase it."
"The solution's support duration or end-of-support life is very short."
"There is room for improvement in simplifying the overall complexity of the environment."
"The pricing should be more competitive."
"The solution's compression needs to be improved, as it's not the best."
"IBM FlashSystem 9100 NVMe is currently at the end of its lifespan and will soon become obsolete in the markets."
"The storage system itself should have built-in capabilities for different ransomware attacks."
"The solution's compression feature could be better."
"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."
"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."
"I would like to have replication functionality built directly in the product, rather than having to use a separate device for this."
 

Pricing and Cost Advice

"Cost-wise, it's been very effective."
"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"All storage is expensive so any price improvement would help."
"We have seen a reduction in TCO."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"The pricing is fair, with additional costs for support services."
"Hitachi VSP E Series is an expensive solution."
"The solution is priced well."
"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 tool's pricing is competitive."
"Compared to its competitors, IBM's offering is the most cost-effective."
"The product has an average cost."
"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."
"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."
