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

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The solution is scalable."
"The most valuable features of this solution are its ease of use and performance."
"Overall stability is very good. It is a very stable solution."
"The most valuable feature of this solution is its ease of use."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"Technical support has been helpful and responsive."
"It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it."
"I have found Dell EMC Unity XT to be stable."
"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."
"Because I always need to trouble shooting for IOPS & database (DB) performance issues. I can quickly focus on what is part of the issue. I can decrease downtime and can plan next year's extended capacity budget."
"After migration to Unity 300F, we were able to put more DBs on flash, reducing latency. The results were visible in the front-end systems, and all users noticed the improvement."
"Snapshots provide a unique feature for testing and make management more comfortable and easy."
"Scheduled components are sourced from Korea based on their quality selection, with the actual purchase taking place in Vietnam. The notable features include cache memories and MOS feeder in Dell Unity. Additionally, the storage dynamics are managed uniformly on a global scale, whether it is a simple or wide-ranging configuration."
"Scalability is good."
"The most valuable feature is the availability."
"Huawei OceanStor is designed with built-in high availability features, such as fault tolerance, ensuring consistent data access and minimizing downtime."
"Huawei OceanStor provides numerous features that are tailored to cater to the requirements of all types of companies."
"The solution is easy to scale as needed."
"The technology seems to be good, especially the performance on their all-flash storage."
"The main selling point of Huawei OceanStor is its ability to handle all storage protocols, including block, file, and object."
"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."
"The most valuable feature of Huawei OceanStor is the hybrid applications."
 

Cons

"It is on the expensive side."
"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."
"I'd like to see the product implement active replication for vehicles such as VMware."
"I would like to see replication and DR features in the next release of this solution."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Adding some functions to the product would be beneficial."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"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."
"As the solution continues to grow and gain more traction, things will come up that will just continue to deepen the integration between VMware, vCenter, and all those other components. Anything in the divisibility there and additional tools is always great."
"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."
"It could always use native replication. Then I could get rid of RecoverPoint."
"It would be great if the solution could integrate an NVMe disk."
"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"It could be a little easier to attach it to a network file system."
"We've also encountered an issue when it comes to migrating to compressed LANs on the Unity, and during the Storage vMotion. It appears that the compression algorithm is overwhelmed, and when it becomes overwhelmed it just stops compressing and writes the raw data to the destination. We later copied internally another Storage vMotion to another compressed LAN and achieved much higher compressions on that internal copy. It would be really nice if there was a way to automatically throttle, as a part of a Storage vMotion, to say, "I want to gain the maximum benefits from the compression algorithm, so throttle back the Storage vMotion to implement 100 percent compression.""
"Compression and block deduplication on non-all-flash solutions."
"The tool's performance is slow for DBs. We plan to move from Huawei OceanStor to Pure Storage. Its customer service is not good."
"Its data replication features work slowly for nodes."
"Configuration complexity and the tools available."
"I would like to see more integration features with different platforms."
"I would like to see the next generation all-flash, which could be combined."
"We did experience a little latency with this solution."
"When it comes to the technical support team, I feel that the response time is an area with certain shortcomings where improvements are required."
"Huawei is not that cheap."
 

Pricing and Cost Advice

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The product is expensive."
"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."
"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."
"Our licensing fees are $500,000+ USD."
"This product is cheaper than the EMC VNX solution. It is good for small businesses."
"I liked the price point when we purchased it."
"There is not a license required for the use of the solution. We purchased a maintenance contract."
"The ROI is right where we need it to be. It's a reasonably priced array."
"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."
"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"The pricing of Dell Unity XT is good."
"The price of the solution could be less expensive. However, there are not any licensing costs."
"Huawei OceanStor is a cost-effective storage solution."
"The price of the license is quite low, so it's not something special or expensive."
"Overall, the solution's pricing was cheaper."
"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 price of Huawei OceanStor should be less expensive. It is expensive at the moment."
"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 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."
