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.

Best for large batch processing and stands out for million of IOPS and ultra-low latency

This is an all-flash storage array. It is the best solution for large batch processing. There are some customer databases that have tens of millions of records in one large database. That's where VIOLIN performs the best. VIOLIN stands out for million of IOPS with ultra-low latency. VIOLIN can provide about two million IOPS in a 3U unit. We have a latency of less than one millisecond.

Quotes from Members

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

Pros

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"Technical support has been helpful and responsive."

"One of the best features is the support, which is excellent."

"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."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

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

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

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

More Pure FlashArray X NVMe pros

"The deduplication features and the graphical user interface (GUI) of the solution are the most valuable to me."

"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 solution's pricing is its most valuable feature."

"Huawei has more features than other vendors. It integrates well with security management solutions, though not directly with databases."

"The most valuable feature of this solution is the overall simplicity."

"The solution is scalable."

"The support team is responsive and effective in addressing any issues that arise."

"Two things really stand out for me. First, there's group cloning, which is very nice. It simplifies managing multiple clones across the group. Second, Huawei's multi-controller architecture with load balancing is a good part."

"This is an all-flash storage array. It is the best solution for large batch processing. There are some customer databases that have tens of millions of records in one large database. That's where VIOLIN performs the best. VIOLIN stands out for million of IOPS with ultra-low latency. VIOLIN can provide about two million IOPS in a 3U unit. We have a latency of less than one millisecond."

Cons

"I'd like to see the product implement active replication for vehicles such as VMware."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

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

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

More Pure FlashArray X NVMe cons

"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."

"The price must be improved."

"The localization problem needs to be improved."

"There could be local support services available for the platform. Additionally, they should provide a bundled license, including all protection and encryption rules."

"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."

"Difficult integration with third parties."

"I would like to see them improve their IOPS per second to match their contemporaries in the industry."

"If they implement a backup solution directly into the OceanStor then it will be a valuable feature."

More Huawei OceanStor Dorado cons

"Its overall usability can be improved. It takes some time to know small things here and there to make sure it is working properly."

Pricing and Cost Advice

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

"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."

"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."

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

"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 licensing is on a yearly basis."

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

More Pure FlashArray X NVMe pricing and cost advice

"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."

"I rate the pricing a six on a scale from one to ten, where one is expensive, not cost-effective, and ten is cheap."

"We saw ROI in terms of both money and time saved. It is worth the price."

"The solution's licensing structure needs improvement."

"In price comparisons with alternative products, it stands out as a more cost-effective option."

"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."

"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."

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

More Huawei OceanStor Dorado pricing and cost advice

"Software licensing is a part of the hardware. There is no separate software license. When you purchase the hardware, it has everything included. It has a one-time initial purchase fee. There is also the annual maintenance and the support maintenance cost. Support and maintenance are a part of the new hardware during the initial one year or three years. After that, support and maintenance are optional."
