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.
Saleem Ahmed - PeerSpot reviewer
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.

Enhanced storage performance and an easy setup with compression challenges
We use IBM FlashSystem 9100 NVMe as a storage device in the IT industry The features I find most valuable include its use for storage and performance. The solution's compression needs to be improved, as it's not the best. Furthermore, support from the partner could also be improved as it's been…

Quotes from Members

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

Pros

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"Everything, especially the VMs inside, is pretty fast."
"The database workloads are pretty fast because I frequently move data from here to there."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"It has benefited my organization because it has reduced time to insights."
"The solution is very straightforward to set up."
"It has good, reliable, fast storage."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"Most of the features which all enterprises storages solutions have are available in Huawei OceanStor Dorado."
"I've been satisfied with the level of attention I'm given when I reach out to technical support."
"The most valuable aspects encompass a comprehensive set of common features, such as NetFlow technology, hyper-micro, and hyper-application functionalities."
"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."
"The most valuable features are the five chips architecture and the purpose-built NVMe hard disk drive. Additionally, the IOPS feature is good."
"Huawei includes features for file servers and file services. It offers ransomware protection for files stored on servers. However, it does not support blocking websites."
"The platform's most valuable features are reliability, intelligence, and fast performance speed."
"The initial setup is straightforward. Deployment takes about a day."
"It is a very stable solution."
"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 FlashCore modules support more value to the architecture due to their unique characteristics."
"The features I find most valuable include its use for storage and performance."
"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 most valuable features of IBM FlashSystem 9100 NVMe are its steady performance and usefulness in high-traffic environments."
"IBM FlashSystem provides the same software on each box, including virtualized solutions."
"The high performance and high availability improved our overall processes."
 

Cons

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"We need better data deduplication."
"The tool's portfolio is minimal. It is expensive."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"The user interface of Huawei OceanStor Dorado could be more user-friendly. Other solutions, such as EMC, have a better user interface."
"The product could always be faster."
"Huawei OceanStor Dorado could improve the integration, there have been some compatibility issues with some operating system functions."
"The initial setup was very complex."
"I would really like to see Heterogeneous Storage Virtualization in a future release."
"This solution can improve by providing easier migrations and better Metro features."
"For future releases, it would be beneficial for OceanStor Dorado to integrate advanced analytics and AI-driven functionalities for predictive maintenance and performance optimization."
"If they implement a backup solution directly into the OceanStor then it will be a valuable feature."
"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."
"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."
"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."
"The storage system itself should have built-in capabilities for different ransomware attacks."
"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."
"The solution's compression needs to be improved, as it's not the best."
"The solution's compression needs to be improved, as it's not the best."
"IBM's support is not good. I experienced a big problem where I opened the console IBM Storage and would see that something was broken. I called the call centers, and I said, "I have a problem. My drive is not working." They want me to give them the serial number, I gave it to them and they told me "I cannot find your product. Your product is not here.""
 

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."
"The product is expensive."
"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."
"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."
"With VMware, we pay $300,000 annually."
"As far as the licensing costs, everything is included in the license."
"The support cost per array is about $20,000 a year for 24/7 support."
"Our licensing fees are $500,000+ USD."
"Huawei OceanStor Dorado is more affordable than the competitor solutions"
"I rate the pricing a six on a scale from one to ten, where one is expensive, not cost-effective, and ten is cheap."
"The pricing is very competitive."
"There are some costs in addition to the standard licensing fees, depending on the requirements."
"The solution's licensing structure needs improvement."
"You need to pay for the license."
"Huawei OceanStor Dorado has a competitive price compared to other solutions."
"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 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."
"The solution is priced well."
"Compared to its competitors, IBM's offering is the most cost-effective."
"The tool's pricing is competitive."
"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 price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."
