Featured Reviews

Jaehoon Oh

Chief Technology Officer at Lambda256

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.

A solution with a simple configuration and good stability but it's quite expensive

Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

Quotes from Members

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

Pros

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

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

"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 most valuable feature of this solution is reliability."

"The initial setup was extremely simple and straightforward."

"The latency is good."

"The solution is scalable."

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

More Pure FlashArray X NVMe pros

"The initial setup was straightforward."

"If your virtual machine that resides on it completely fills the storage space, thanks to it's built-in function of all-zero data space reclamation, you just have to ask to System Engineer to run a zero-free on hosts (thin provisioned) and you will get more space instantaneously."

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

"The solution works well for non-critical applications that do not require a heavy workload. The tool's all features are valuable."

"Huawei OceanStor offers good IOPS and is reliable and energy-efficient."

"The most valuable feature is the availability."

"This is a stable storage system."

"The solution has improved our organization by speeding up our operations."

More Huawei OceanStor pros

"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."

"Logic/software management"

"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."

"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."

"The ratio between the physical storage and the storage we use is very high."

"Inline compression"

"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."

"The speed and, for us in particular in what we're doing, the data de-duplication."

More Kaminario K2 [EOL] pros

Cons

"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."

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

"It is on the expensive side."

"The tool's pricing is higher than competitors."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

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

"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."

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

More Pure FlashArray X NVMe cons

"Configuration complexity and the tools available."

"The user interface is not so user friendly."

"The speed has room for improvement."

"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. The data store ran out of space, and Huawei had to send a new unit."

"The deployment took a little longer."

"Could have a more stable, lighter Metro and better logging system."

"The main concern is regarding the usability of the data storage."

More Huawei OceanStor cons

"A single pane of glass to monitor/manage multiple arrays would be helpful."

"Improved scale and budget planning with flexibility of the solution for budget needs and efficiency for growth with the great optimization ratio due to the nature of our use."

"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."

"I would love to see capacity on its DRAM. I know it's not cost effective for them to do it, but I think that it could be a big differentiator and was a big differentiator from the beginning."

"The system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."

"The management graphical interface needs more improvement."

"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."

"I would like them to improve the look of the product’s external casing and shelves."

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

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

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

"The product is expensive."

"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."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

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

"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 licensing is on a yearly basis."

More Pure FlashArray X NVMe pricing and cost advice

"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."

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

"The product is cheap."

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

"Huawei OceanStor is priced very well but is a bit complicated."

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

"Its price is affordable."

"It's roughly affordable."

More Huawei OceanStor pricing and cost advice

"The licensing is all-inclusive."

"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."

"Kaminario is very competitive on price. They also have a pay per TB model."

"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."

"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."

"Licensing is very straightforward. The cost was considerably lower than other products we looked at."

"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."
