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.

Storage Engineer at Movate

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

AmanullahMehmood

Pre-Sales Manager at a tech services company with 51-200 employees

Offers better price and features compared to its competitors

The technical support for the solution is very good. Huawei, in our region, has more than 2,000 employees in the office, and they mostly have post-sales engineers for storage, servers, and networks. Huawei also trains its partner engineers on the storage it offers. If a customer faces any problem, then a partner engineer will first resolve it. If an issue is not resolved in the tool, then Huawei engineers get involved, and the case gets lodged with Huawei's tech team, after whom a Huawei engineer will come. The partner, a tech team, and then a Huawei engineer get involved in the support process. I rate the technical support 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

"I appreciate the performance."

"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."

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

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

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

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

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

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

More Pure FlashArray X NVMe pros

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"High performance and ease-of-management are the most valuable features."

"Data Compression: Up to 80% space reduction in the database"

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

"The initial setup is straightforward."

"We use IntelliFlash products for larger environments, like Qatar Airways."

More DDN IntelliFlash pros

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

"Huawei OceanStor is designed with built-in high availability features, such as fault tolerance, ensuring consistent data access and minimizing downtime."

"We get a quick response in case any component defaults. We have seen the benefits mostly."

"The support is excellent."

"Huawei is much cheaper compared to Dell, offering a competitive price that makes companies consider their options."

"It is a highly available product."

"The initial setup was straightforward."

"The solution is easy to scale as needed."

More Huawei OceanStor pros

Cons

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

"There is room for improvement in the pricing of the product."

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

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

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

"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."

"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."

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

More Pure FlashArray X NVMe cons

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

"In future releases, I look forward to more AI features."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"It's somewhat scalable, but maybe not so much as some of the competition."

"Snapshots are not as easy to access as on a NetApp device."

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

More DDN IntelliFlash cons

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

"Unfortunately, this product doesn't support Flash Disks, but it's IOPS capacity is a great compromise."

"I would like to see more integration features with different platforms."

"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 solution could improve by having better integration."

"We did experience a little latency with this solution."

"Its storage capacity could be better."

"I would like to see the next generation all-flash, which could be combined."

More Huawei OceanStor cons

Pricing and Cost Advice

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

"The product is expensive."

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

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

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

"The licensing is on a yearly basis."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"I think we pay around 100 grand per year for three arrays or four arrays."

"Pricing is very fair."

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

"The tool's pricing is competitive and affordable. It has the best possible pricing that we can get from Huawei. The prices are fixed and there are no additional costs."

"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."

"The price of the solution could be less expensive. However, there are not any licensing costs."

"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."

"It's roughly affordable."

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