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 has low latency and high Ops. It is an evergreen model."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"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."
"The most valuable feature of this solution is its ease of use."
"The most valuable feature of this solution is reliability."
"The latency is good."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"The Snapshot feature is key."
"It is easy to scale, maintain, and manage."
"The solution overall has high performance."
"On the Data Domain side, the most attractive feature is the compression ratio, which none of the other products in the market are currently able to provide. On the Unity side, what customers mostly like is the availability guarantee."
"Initial setup is a simple process."
"Setup is simple."
"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."
"Storage Snapshots have been really nice. They allow us to do backups without impacting our production workload that much. The scalability, the ability to add disks dynamically and adjust our workload as needed, has also been really helpful. That definitely makes my job easier. And the interface for managing Unity is very easy. The integrations between VMware Hypervisor and Dell EMC are top-notch, so it's been really easy to use and manage."
"The most valuable features of Huawei OceanStor are the dashboards, bandwidth, and data performance."
"Huawei OceanStor is easy to manage."
"Huawei OceanStor is stable and reliable for storage solutions."
"OceanStor is cheaper than Dell EMC, and its management interface is quite simple."
"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 support is excellent."
"Huawei OceanStor has the capability of SSDs, high-performance disks, and higher disk support."
"Huawei OceanStor is designed with built-in high availability features, such as fault tolerance, ensuring consistent data access and minimizing downtime."
 

Cons

"It feels more suitable for small and medium-sized businesses rather than enterprises."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"We need better data deduplication."
"In terms of what needs improvement, the dashboard and management could be simplified."
"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."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"There are some challenges with data encryption and reduction."
"We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions."
"The iSCSI and the VMware integation using vSphere could be less confusing."
"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."
"We would like to see the concept of Storage Groups brought back to this product line."
"Thick provisioning of LUNs."
"It needs more functionality and the ability to move across more landscapes."
"The user interface could use improvement."
"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."
"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 administration should be simplified because there are a large number of options that make it too complicated, and the customers can get confused."
"The duration of the built-in snapshot technology must be improved."
"In terms of marketing, they need to improve by putting more effort into making people aware of their products, especially in our region."
"Unfortunately, this product doesn't support Flash Disks, but it's IOPS capacity is a great compromise."
"Huawei currently lacks a solution for high-performance AI, unlike other companies like DDN, WekaIO, or IBM BlueStore."
"Huawei is not that cheap."
"The speed has room for improvement."
 

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."
"The licensing is on a yearly basis."
"Given its price, Pure is not the first option."
"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."
"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 support cost per array is about $20,000 a year for 24/7 support."
"We pay approximately $50,000 USD per year in licensing fees."
"With VMware, we pay $300,000 annually."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."
"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."
"This solution offers great pricing."
"Looking at it based on cost per gigabyte, it's certainly very effective."
"It scales, but then you have to buy additional stuff."
"Huawei OceanStor is a cost-effective storage solution."
"The price of the solution could be less expensive. However, there are not any licensing costs."
"The price of Huawei OceanStor should be less expensive. It is expensive at the moment."
"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 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."
"It's roughly affordable."
"Pricing is very fair."
"Huawei OceanStor is priced very well but is a bit complicated."
