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.
Syed Habib - PeerSpot reviewer
Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.

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

"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 system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"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 is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"Technical support has been helpful and responsive."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The solution uses newer technology for deduplication and compression."
"Being all-flash makes everything super-fast. It's also great to manage. That's the easiest part. We also have another SAN, from Pure, and the Unity is easier to manage than the Pure."
"I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product."
"Key features are ease of use, ease of management, ease of deployment, and the GUI is very user-friendly."
"It has helped us be able to use less administrators per device or system. Therefore,we are more streamlined."
"The most valuable feature of Dell Unity XT is its support of protocols for both block, and file levels. It has the features a store solution should have."
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"The valuable features of Unity include that it's flexible, has a friendly user-interface, and provides good performance."
"I like that the performance is very good."
"OceanStor is cheaper than Dell EMC, and its management interface is quite simple."
"The support is excellent."
"Huawei OceanStor provides numerous features that are tailored to cater to the requirements of all types of companies."
"The main selling point of Huawei OceanStor is its ability to handle all storage protocols, including block, file, and object."
"Generally stable with good technical support."
"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."
"This is a stable storage system."
 

Cons

"The tool's pricing is higher than competitors."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"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."
"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."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"Adding some functions to the product would be beneficial."
"In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside."
"The storage processors have less port expansion than previous high-end VNX arrays. Data compression is only available in all-flash pools."
"The support team is well-versed in the AMG solution, having received comprehensive training. They also boast strong partnerships in both VNAM and Korea. The system's user-friendliness is a primary consideration in their choice of solution, emphasizing the importance of service. They place a strong emphasis on service, occasionally requiring approvals. However, with full installations, they have achieved almost uniformity. Their storage approach differs from a consolidated business-based model; instead, it is application-centric. Their investment in solutions is geared towards specific needs, such as the banking or information system, acquiring smaller storage units individually."
"Inline dedup compression security is coming up as an issue, encryption, etc. is key for our customers. If we could have more ways to do software-based encryption, those are the features customers are asking us for, as well as replication."
"Sometimes the response time is higher than expected due to a lack of issues."
"The pricing is a bit higher than expected."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"Stability is the problem. We've had stability issues with it. We've had problems with the iSCSI interface. We've had it for two years now and for two years we've had problems where a service processor will drop, we'll lose connectivity to LUNs, we'll lose connectivity to the storage, issues like that. No matter how we've tried to chase it down, everybody just points fingers at each other. The only thing that changed in our environment was that the Unity solution was installed."
"Could have a more stable, lighter Metro and better logging system."
"The price could be better. It's not good for the Brazilian market."
"The deployment took a little longer."
"Unfortunately, this product doesn't support Flash Disks, but it's IOPS capacity is a great compromise."
"From a political perspective, there are issues selling Chinese brands to Western companies, as some may not be permitted to use them."
"Huawei is not that cheap."
"Huawei currently lacks a solution for high-performance AI, unlike other companies like DDN, WekaIO, or IBM BlueStore."
"Its storage capacity could be better."
 

Pricing and Cost Advice

"We pay approximately $50,000 USD per year in licensing fees."
"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 licensing is on a yearly basis."
"As far as the licensing costs, everything is included in the license."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"With VMware, we pay $300,000 annually."
"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."
"The license is not required, but we must renew the support every year, every two years."
"The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."
"This product is cheaper than the EMC VNX solution. It is good for small businesses."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"The ROI is right where we need it to be. It's a reasonably priced array."
"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."
"The solution is very expensive."
"It's roughly affordable."
"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."
"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 product is cheap."
"This product value matches its price."
"Huawei's prices are very good compared to those of its competitors."
"Pricing is very fair."
"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."
