Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Uses a proprietary technology with simple interface and has easy deployment

If you are not generating a substantial amount of data, the available storage space might suffice, making scalability less of a concern. However, if your data generation increases and you require more storage, Huawei OceanStor offers solutions to expand your storage capacity. Expanding storage resources can involve additional costs and configuration efforts. Acquiring more storage solutions and ensuring their integration with your existing setup might require a significant investment of time and resources. While this process can be complex, it allows for seamless scalability as your data storage needs grow. I rate the solution’s scalability an eight out of ten.

Quotes from Members

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

Pros

"It has benefited my organization because it has reduced time to insights."

"Technical support has been helpful and responsive."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

More Pure FlashArray X NVMe pros

"Stability: The product is designed to have always HA (High Availability) with redundant network and processors."

"The technology seems to be good, especially the performance on their all-flash storage."

"The solution is easy to scale as needed."

"The main selling point of Huawei OceanStor is its ability to handle all storage protocols, including block, file, and object."

"The solution is easy to use."

"The most valuable feature is the availability."

"Huawei OceanStor has the capability of SSDs, high-performance disks, and higher disk support."

"Huawei OceanStor is stable."

More Huawei OceanStor pros

"IBM FlashSystem 9100 NVMe is one of the leading storage systems in the world...I rate the solution's stability a ten out of ten."

"The FlashCore modules support more value to the architecture due to their unique characteristics."

"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."

"The most valuable features of IBM FlashSystem 9100 NVMe are its steady performance and usefulness in high-traffic environments."

"It is a very stable product. Stability-wise, I rate the solution a ten out of ten because we did not face any issues in the last three years."

"The high performance and high availability improved our overall processes."

"IBM FlashSystem provides the same software on each box, including virtualized solutions."

"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."

Cons

"The software layer has to improve."

"Maybe the price can be reduced since the solution is very expensive."

"They could add more support for file storage and different types of storage."

"The UI for this solution needs to be improved."

"The tool's portfolio is minimal. It is expensive."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"In the future, I would like to see integration with enterprise backup systems."

More Pure FlashArray X NVMe cons

"The security could be a bit more robust."

"The price could be better. It's not good for the Brazilian market."

"Based on what we were quoted, the stated capacity was not a true reflection of the actual capacity."

"Its data replication features work slowly for nodes."

"Its storage capacity could be better."

"They should introduce a feature to Huawei OceanStor similar to a storage controller, allowing for seamless integration of additional storage modules."

"Configuration complexity and the tools available."

"The duration of the built-in snapshot technology must be improved."

More Huawei OceanStor cons

"The solution's compression feature could be better."

"IBM is currently not offering volume-based encryption or compression, while other brands or IBM's competitors are doing it."

"The pricing should be more competitive."

"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 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 needs to be improved, as it's not the best."

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."

"The licensing is on a yearly basis."

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"With VMware, we pay $300,000 annually."

"Given its price, Pure is not the first option."

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

More Pure FlashArray X NVMe pricing and cost advice

"This product value matches its price."

"The price of Huawei OceanStor should be less expensive. It is expensive at the moment."

"Pricing is very fair."

"Huawei OceanStor is a cost-effective storage solution."

"Overall, the solution's pricing was cheaper."

"The pricing depends on the features the customer wants, such as storage, RAM, and processors, but in general, Huawei is much cheaper compared to Dell and Cisco."

"Huawei's prices are very good compared to those of its competitors."

"The price of the license is quite low, so it's not something special or expensive."

More Huawei OceanStor pricing and cost advice

"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."

"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 its competitors, IBM's offering is the most cost-effective."

"The solution's price is competitive."

"The tool's pricing is competitive."

"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."
