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.

Inexpensive with fast performance enhances data storage efficiency
We are using Huawei OceanStor Dorado for Hyper Metro and under Datacore products and some Sunpro products Huawei OceanStor Dorado is fast and has significantly improved data storage efficiency. The fast performance and reasonable pricing of Huawei OceanStor Dorado are the main reasons we sell…

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

"It helps to simplify storage. For most of our customers, when they move to Pure Storage, storage becomes an afterthought."
"The availability and ease of use are the big features."
"The performance and the ever-growing maintenance are the most valuable features of this solution."
"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."
"When you put all of the features in a box, leverage them and migrate your application to one of these arrays, it will give you a lot of benefits."
"The speed is the most valuable feature, along with the ease of getting it connected. We were able to get it online in less than a day."
"The initial setup was really straight forward."
"We have seen savings in our storage, and the speed of deployment has gone from several days to a few minutes, reducing backup and restore times from 93 days to minutes and simplifying storage for us."
"The product offers good performance."
"The platform’s most valuable features are speed, accuracy, and encryption."
"The initial setup is straightforward. Deployment takes about a day."
"Huawei OceanStor Dorado is a stable solution."
"My advice to anybody who is considering OceanStor Dorado is that it is a very reliable solution with good features."
"The fast performance and reasonable pricing of Huawei OceanStor Dorado are the main reasons we sell them."
"Huawei OceanStor Dorado is equipped with powerful controllers"
"The most valuable features of the solution are SmartMigration, HyperReplication, HyperSnap, HyperCopy, HyperClone, SmartPartition, and SmartCache."
"IBM FlashSystem provides the same software on each box, including virtualized solutions."
"It is a high-performance product that serves our requests well."
"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."
"The solution is more available for IOPS warehousing, resolving issues, and reporting than other products."
"It is a very stable solution."
"The features I find most valuable include its use for storage and performance."
"The most valuable feature of the solution is its upgrades, as we don't have to do much homework because of its different controllers."
"The most valuable feature is the speed."
 

Cons

"In the next release, I would like to see file-level encryption."
"I would like to see support for NVMe, end-to-end."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"The price of Pure Storage FlashArray could be better."
"Pricing could be better in comparison to other solutions."
"Pure Storage FlashArray has not helped decrease the total cost of ownership."
"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 some form of QoS implemented. As a service provider, it would be beneficial to have it."
"The logistics can be improved because sometimes we have to wait a long time for the product to be delivered, despite there being stores available in Europe."
"I would really like to see Heterogeneous Storage Virtualization in a future release."
"One of the key areas that need enhancement pertains to the software procurement process."
"Some customers have reported not understanding how the immutable part can be unlocked."
"The user interface of Huawei OceanStor Dorado could be more user-friendly. Other solutions, such as EMC, have a better user interface."
"Huawei should provide new security features, such as blocking ransomware sites and improving detection. Currently, we receive updates from HQ in China; there are instances where hackers may infiltrate network sites and encrypt our data."
"The data compression and deduplication ratio of Huawei OceanStor Dorado is not as good as other solutions, such as EMC and Pure Storage. It is important when looking at capacity effectiveness."
"For future releases, it would be beneficial for OceanStor Dorado to integrate advanced analytics and AI-driven functionalities for predictive maintenance and performance optimization."
"Other vendors have included a block and file system. IBM doesn't include a file system."
"The solution's compression needs to be improved, as it's not the best."
"IBM is currently not offering volume-based encryption or compression, while other brands or IBM's competitors are doing it."
"The storage system itself should have built-in capabilities for different ransomware attacks."
"In the future, the limitation is upgrading the same storage by adding a shelf to the desk. There is a limitation in the backend connection between the storage and extended shelf."
"We're not satisfied with the deduplication and compression for our volumes."
"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."
"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."
 

Pricing and Cost Advice

"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"We have seen a reduction in total cost of ownership (TCO)."
"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"Cost-wise, it's been very effective."
"The price, in general, is around $100,000, however, I know it costs more."
"The cost was initially high, but once more people were using it, the costs came down. This was because the University was reselling it to other departments."
"The pricing is reasonable."
"The price of the solution is reasonable. There is not a vendor that offers an All-Flash Storage Array at the price of Huawei OceanStor Dorado. The other solutions are approximately 50% higher."
"The price of Huawei OceanStor Dorado is very inexpensive, it cost approximately $5 per gigabyte."
"The price of the solution is competitive compared to others, such as Dell EMC and Hitachi. I believe the reason they are providing a discount is they want to increase their penetration into the market."
"You need to pay for the license."
"This product is not too expensive, and the price is competitive on the market."
"There are some costs in addition to the standard licensing fees, depending on the requirements."
"Huawei OceanStor Dorado is more affordable than the competitor solutions"
"We usually recommend our customers choose advanced licensing and enterprise companies are more inclined to choose this solution because it is more cost-effective than competitors."
"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 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."
"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."
"The product has an average cost."
"Compared to its competitors, IBM's offering is the most cost-effective."
