Eugene Hemphill - PeerSpot reviewer
Helps to save money and resources with the data compression feature
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. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Delivers essential support and performance for intensive operations in real-time environments
Our infrastructure is spread across the private as well as a public cloud. Our requirement was that the IOPS latency should not be more than one millisecond. If anything goes beyond one millisecond, it's a problem for us. We wanted a system that could handle the transactions and meet our latency requirements. There are performance benefits for sure. The amount of deduplication and compression offered by Dell PowerMax is quite good, especially with databases. Dell PowerMax delivers optimum performance and reliable support, integral for handling failures and ensuring operational continuity. The performance capacity optimization and support we receive from Dell are also valuable.

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

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"Everything, especially the VMs inside, is pretty fast."
"It has benefited my organization because it has reduced time to insights."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"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."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"It has good, reliable, fast storage."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"The benefits of Dell PowerMax are that we can use the older environment."
"We removed the need to observe whether we ran into issues with the performance of disks or number of IOPS. Previously, our Oracle Database would throw us performance errors. Now, with PowerMax, everything runs smoothly."
"It is a fantastic Dell EMC product ever competing with all the vendors. It stands out in terms of performance. You can ask for mission-critical application workloads."
"Dell PowerMax is pretty much 100%."
"Dell PowerMax NVMe is very supportive of our operational growth since we require daily performance from our core banking systems and need to facilitate data movement efficiently."
"It is a very stable solution. I would rate it a ten out of ten."
"Dell PowerMax NVMe has been a significant enhancement for data handling in my industry. Its improved security features and data calculation capabilities make it a valuable solution for our customers. The most critical feature of Dell PowerMax NVMe for performance enhancement is its strong network support and integration with other vendors, along with its efficient use of hardware components like CPU and memory. Data reduction technologies in PowerMax have been highly beneficial for our company, allowing us to optimize storage and reduce costs by consolidating files"
"The UI is very easy to use. We can add volumes and manage them easily."
"Huawei OceanStor has the capability of SSDs, high-performance disks, and higher disk support."
"The solution has improved our organization by speeding up our operations."
"The performance and ease of management are the most valuable features."
"It is a highly available product."
"The solution is easy to use."
"The initial setup was straightforward."
"The most valuable features of Huawei OceanStor are the dashboards, bandwidth, and data performance."
"The support is excellent."
 

Cons

"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."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"In terms of what needs improvement, the dashboard and management could be simplified."
"The tool's portfolio is minimal. It is expensive."
"They could add more support for file storage and different types of storage."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"Support of the product can be slow and an administrative challenge: planning, scheduling, and overseeing data center access for a Dell EMC rep. One improvement could be to enable a self-maintenance option. The requirements that we go through to get Dell EMC onsite to replace failed drives, power supplies, and other small redundant parts can be unnecessarily complex. If simplified, they could send us the parts, then we could replace them much faster, more easily, and truly within the SLA parameters."
"Although they call it unified storage where you have SAN and NAS, with a NAS implementation on top of a SAN, the NAS implementation is a little complicated and clumsy. As SAN, as block storage, it is very powerful... If they could provide a very good NAS implementation, it would be better, so that customers don't have to look for other simple solutions for NAS."
"The installation of equipment needed support's help."
"Dell PowerMax needs more connectivity options for projects that require separate web access."
"I believe it would be of great benefit to work on the customization of the pricing structure for different enterprises and their specific needs."
"The initial setup was complex, as it is a complex system and you have to learn a lot."
"They should work with the storage engineers to better tweak the management tools to give them improved visibility into their data."
"Dell PowerMax NVMe needs to increase storage and improve scalability."
"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."
"I would like to see more iterations and direct integration with other solutions."
"The overall price of the solution should be reduced."
"The main concern is regarding the usability of the data storage."
"In the future release, Huawei OceanStor should improve on what they already have. It is a good solution."
"The solution could improve by having better integration."
"The upgrading process needs improvement. Deploy it and notify the customers when new versions and stuff comes out. I don't think they're doing that well."
"The security could be a bit more robust."
 

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."
"We pay approximately $50,000 USD per year in licensing fees."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"Given its price, Pure is not the first option."
"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."
"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 support cost per array is about $20,000 a year for 24/7 support."
"It is high-end storage and it is a bit expensive, but it is doing what it is meant for: running business-critical applications or latency-sensitive applications..."
"The price is okay."
"The tool is very expensive."
"I think it is an expensive tool, but it is the best product. I think it is expensive and the cost one must pay for the best solution."
"From reclaiming data center space which is so tightly constrained these days, it will pay for itself in a short amount of time, which is fantastic. Anything we can do to get more out of our current physical data center space helps us a ton, and PowerMax has helped enable that."
"In terms of price-performance, it beat out other competitors when we were taking a look and comparing it to the market. That was one of the biggest driving points for us."
"The PowerMax appliance pricing was reasonable. Dell EMC quoted us a substantial discount."
"The cost is expensive. While VMAX now has good pricing, PowerMax is a little expensive."
"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."
"Huawei OceanStor is a cost-effective storage solution."
"The price of the solution could be less expensive. However, there are not any licensing costs."
"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."
"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."
"The price of the license is quite low, so it's not something special or expensive."
"Huawei's prices are very good compared to those of its competitors."
"Overall, the solution's pricing was cheaper."
