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.

Efficient and straightforward setup boosts data management capabilities

Scalability is a significant feature of Dell XtremIO, as it is easy to expand and manage. It provides a lot of features suited for complex systems, such as scalability and the ability to define multi-domain systems, which are beneficial for data management and storage separation. It is efficient from the customer's point of view, offering deduplication at both the volume and file levels. The configuration and setup are straightforward, provided one has knowledge in setting up network infrastructure like VLANs. It is easy to install, use, and configure, making it a reliable product.

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.

Quotes from Members

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

Pros

"The high availability of the product is the most valuable feature."

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

"It has good, reliable, fast storage."

"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."

"The solution is scalable."

"Technical support has been helpful and responsive."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

More Pure FlashArray X NVMe pros

"Deduplication and cloning capability"

"Performance and deduplication. This is a very robust block storage option that offers both performance and data optimization."

"We mostly use it for backup, because we cannot measure anything, and we are afraid to use it for surveillance systems. We were planning to use it for mostly for surveillance systems."

"Linear performance – The XtremIO wasn’t the fastest in all tests against other all flash arrays, but even with a massive workload, the response time and user experience were absolutely predictable with no sharp drop-offs."

"Ease of management, aside from the serious performance, is the best feature."

"The most valuable feature of the solution is its performance."

"I like the deduplication and auto-tiering features."

"The most valuable features are: complete performance and ease of use."

More Dell XtremIO pros

"Huawei OceanStor provides numerous features that are tailored to cater to the requirements of all types of companies."

"The technology seems to be good, especially the performance on their all-flash storage."

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

"Huawei OceanStor is a good product. Its interface is very simple. The complexities we encounter with recovery points are gone. We just attach to remote storage, click the application, and it starts."

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

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

"Huawei OceanStor utilizes a proprietary technology known as RAID 2.0. This technology sets it apart from conventional storage solutions. RAID 2.0 offers advantages over traditional configurations. OceanStor's user interface is very simple and easy to use, featuring a graphical interface that enables quick and error-free setup of the storage system. This interface ensures that users can configure the storage efficiently and without mistakes."

"Generally stable with good technical support."

More Huawei OceanStor pros

Cons

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

"They could add more support for file storage and different types of storage."

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

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

"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."

"It is on the expensive side."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

More Pure FlashArray X NVMe cons

"One thing that should be improved is the reporting and monitoring tools. It should use real time monitoring for storage, IOPS, latency, etc."

"The solution needs to be simplified. When you integrate your storage with other systems, could use a little bit of automation."

"The product is highly expensive. Additionally, there is a significant lack of training, support documents, and forums available for Dell XtremIO, making troubleshooting difficult for third-party individuals."

"The physical architecture could use some higher levels of redundancy."

"Management: At the time, there was no snapshot scheduler, so I had to write XSnapCourier to address it. The sad thing is that even after the newest release, which includes a native scheduler, most customers using XSnapCourier chose to stick with it due to a more feature-rich experience."

"Dell's technical support could be better."

"The product could be improved by reducing the pricing and having better organization in their technical support team."

"In some cases where we don’t need the flexibility of the virtualization layer, we could free up resources on the VPLEX by using the storage replication."

More Dell XtremIO cons

"The product must improve the local technical support in China."

"The overall price of the solution should be reduced."

"The solution needs to improve the compression side of the application."

"The price could be better. It's not good for the Brazilian market."

"I would like to see more iterations and direct integration with other solutions."

"The security could be a bit more robust."

"Integration with mainstream solution technologies could be better."

"The administration should be simplified because there are a large number of options that make it too complicated, and the customers can get confused."

More Huawei OceanStor cons

Pricing and Cost Advice

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

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

"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."

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

"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 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."

"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."

"The licensing is on a yearly basis."

More Pure FlashArray X NVMe pricing and cost advice

"You can get a two-year or three-year license for the tool. You can also opt for a perpetual-based licensing model, which can be renewed on a yearly or two-year basis."

"It's not cheap, but it absolutely gets the job done. I don't have any real comment regarding licensing specifically."

"It is expensive if you need to increase scalability."

"Licensing is approximately $200,000 per year."

"The initial purchase price was good but when you need to upgrade, it's a different story."

"With some workloads that benefit from compression and deduplication, costs are actually better than some tier 2 subsystems (while latency remains <1ms)."

"Pricing and licensing are in line with other products from other manufacturers. You get what you pay for."

"Dell XtremIO's price is affordable and I would rate it a five out of ten."

More Dell XtremIO pricing and cost advice

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

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

"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 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."

"Huawei OceanStor is a cost-effective storage solution."

"Huawei's prices are very good compared to those of its competitors."

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

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