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

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"The solution uses newer technology for deduplication and compression."
"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."
"Overall stability is very good. It is a very stable solution."
"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."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"The high availability of the product is the most valuable feature."
"I like the easy management with the new Unisphere management and the HTML5 interface."
"We run about 100 virtual servers on it. We have about 100 users accessing the file shares from there, and I've seen no problem with that. We have about a 10GB backbone. Whatever we throw at it, it hasn't shown any sign of weakness or anything. It's been really good."
"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."
"For sites that we use it on, it gives us more flexibility and high availability solutions. It is easier to expand the site, if needed."
"We can get almost real-time response times."
"Unified block and file storage without the need of control stations and data movers. This simplifies administration and deployment and requires less rack space."
"Ease of use is probably number one, compared to the previous storage that we've had. Easy scalability, easy set up. Compared to everything else, the Unity is, well, you could call it child's play. As long as you know what you're doing storage-wise, Unity is really easy to use."
"The replication is big for us. We use file services on Unity and it has a really nice file services interface. It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy."
"The pricing is very reasonable."
"I find the scalability features of OceanStor valuable. Additionally, installation is easy, and it only requires one person to install it. Maintenance is also easy and not a big issue."
"Huawei OceanStor offers good IOPS and is reliable and energy-efficient."
"The most valuable feature is the flexibility in the rail, as it is hybrid storage."
"It is easy to use, deploy, communicate and manage this solution."
"Huawei OceanStor is stable."
"The solution has improved our organization by speeding up our operations."
"This is a stable storage system."
 

Cons

"They could add more support for file storage and different types of storage."
"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."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"The UI for this solution needs to be improved."
"The tool's pricing is higher than competitors."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup. This would help us minimize our IT cost in terms of the backup procedures."
"Dell Unity XT could add a unit-to-unit replication. We haven't seen that because we don't have an additional one to test. However, it is not an improvement, but something that we would like to have visibility on how it's done or how it works."
"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."
"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."
"It would be great if the solution could integrate an NVMe disk."
"The pricing is a bit higher than expected."
"In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful."
"Integration with mainstream solution technologies could be better."
"The security could be a bit more robust."
"The speed has room for improvement."
"Huawei OceanStor should work on its saturation level and should be able to take up more load. It should give the same performance that it gives at 20 or 30 percent load for 80 percent as well."
"We did experience a little latency with this solution."
"A concern with OceanStor is pricing. However, apart from that, there are no significant limitations or technical issues."
"Technical support could be more helpful."
"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."
 

Pricing and Cost Advice

"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."
"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 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."
"We pay approximately $50,000 USD per year in licensing fees."
"The product is expensive."
"As far as the licensing costs, everything is included in the license."
"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"While Dell EMC is costly, I don't have any complaints about their licensing model."
"The ROI is right where we need it to be. It's a reasonably priced array."
"This solution offers great pricing."
"We checked both HP and Dell and we determined that Dell EMC was a better option."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"The product’s pricing should be improved."
"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."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"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."
"Overall, the solution's pricing was cheaper."
"Huawei OceanStor is a cost-effective storage solution."
"The price of Huawei OceanStor should be less expensive. It is expensive at the moment."
"The price of the solution could be less expensive. However, there are not any licensing costs."
"The price of the license is quite low, so it's not something special or expensive."
"Its price is affordable."
"This product value matches its price."
