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.

A highly stable solution that provides features like SmartMigration, HyperReplication, and SmartPartition

Other Huawei mid-end storages, like 5600 and 5500, are very easy to use. Engineers with two to three years of experience with Huawei will find that Huawei OceanStor Dorado is a bit complicated to use compared to other Huawei storages. Unlike other storages, you cannot configure the disk domain and storage pool in Huawei OceanStor Dorado.

Quotes from Members

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

Pros

"The database workloads are pretty fast because I frequently move data from here to there."

"The solution uses newer technology for deduplication and compression."

"What I really like about this program, is that it is easy to use and easy to configurate."

"The most valuable feature of this solution is its ease of use."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

"Everything, especially the VMs inside, is pretty fast."

More Pure FlashArray X NVMe pros

"This is a stable product that we can use for DR in production."

"The most valuable feature for me is that it deduces better, whereby it can be assigned six times the usable capacity, depending on the nature of the data."

"Has good capacity, is effective and easy to manage."

"There are plenty of features available in this solution."

"The solution is scalable."

"The majority of our customers find this solution simple to use."

"The most valuable aspects encompass a comprehensive set of common features, such as NetFlow technology, hyper-micro, and hyper-application functionalities."

"The performance is good."

More Huawei OceanStor Dorado pros

"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 most valuable feature of the solution is its upgrades, as we don't have to do much homework because of its different controllers."

"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."

"IBM FlashSystem 9100 NVMe is easy to use and comes with good performance."

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

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

"The most valuable feature of IBM FlashSystem 9100 NVMe is the snapshot. We use it daily for all of the storage units."

More IBM FlashSystem 9100 NVMe pros

Cons

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"The software layer has to improve."

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"There are some challenges with data encryption and reduction."

"Adding some functions to the product would be beneficial."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"It is on the expensive side."

More Pure FlashArray X NVMe cons

"This solution can improve by providing easier migrations and better Metro features."

"Having distinct modules for data compression and encryption features enhances flexibility and performance optimization for users with varying requirements."

"Huawei OceanStor Dorado's biggest weakness is its lack of cloud integration."

"The speeds of the disks themselves need to be faster. The disks are not flash. When we opened our hard drive from the inclusion, I saw a converter, and it's not entirely flash."

"In additional features, it would be easier to do snapshots on a regular basis. So, like, a new feature that would allow you to take snapshots every hour."

"An area of this product that has room for improvement is the NAS capability."

"Huawei OceanStor Dorado could improve the integration, there have been some compatibility issues with some operating system functions."

"This solution does not support VMware VVols 2.0."

More Huawei OceanStor Dorado cons

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

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

"I would like to see IBM products become more affordable because they can be quite expensive, which limits their accessibility to a broader customer base."

"I would like to have replication functionality built directly in the product, rather than having to use a separate device for this."

"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."

"The tool's architecture is complex. It also needs to add data utilization reports."

"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."

Pricing and Cost Advice

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"The support cost per array is about $20,000 a year for 24/7 support."

"Our licensing fees are $500,000+ USD."

"The licensing is on a yearly basis."

"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."

"We pay approximately $50,000 USD per year in licensing fees."

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

More Pure FlashArray X NVMe pricing and cost advice

"The pricing is one thing that works for them. I think their pricing is more competitively affordable than these top competitors."

"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."

"There are lots of features included with this solution and some of them require additional licensing, such as creating high availability storage using a cluster."

"It stands out as the fastest purpose-built storage solution available on the market, and the pricing is highly competitive and excellent."

"Huawei has very good pricing. They have some promotions that can be taken advantage of at certain times of the year, such as the end of December. They are providing aggressive pricing. In the Pakistan market, they are ready to beat any vendor in Pakistan because they want to grab the market."

"The solution's licensing structure needs improvement."

"This product is not too expensive, and the price is competitive on the market."

"It's not easy to receive an upgrade license of Huawei OceanStor Dorado. It's easy to buy OceanStor with several features, but when you want to add on features later it's not easy. I had some problems."

More Huawei OceanStor Dorado pricing and cost advice

"The solution's price is competitive."

"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 price of the FlashSystem 9100 NVMe is reasonable."

"On a scale of one to ten, where one is a low price and ten is a high price, I rate the pricing an eight."

"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."

"The tool's pricing is competitive."

"The solution is priced well."
