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.

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.

Reliable and fast servers with good support
We use on-premise servers with Lenovo ThinkSystem. We set up Hyper-V and load multiple types of servers including a domain controller, a SQL Server, and application servers The solution provides fast servers that are reasonably priced. We set up RAID ten to ensure drive redundancy, leading to…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The database workloads are pretty fast because I frequently move data from here to there."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"The latency is good."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"The solution uses newer technology for deduplication and compression."
"Overall stability is very good. It is a very stable solution."
"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 technology seems to be good, especially the performance on their all-flash storage."
"Huawei OceanStor is easy to manage."
"If your virtual machine that resides on it completely fills the storage space, thanks to it's built-in function of all-zero data space reclamation, you just have to ask to System Engineer to run a zero-free on hosts (thin provisioned) and you will get more space instantaneously."
"Generally stable with good technical support."
"The main selling point of Huawei OceanStor is its ability to handle all storage protocols, including block, file, and object."
"Great value for money."
"The solution is easy to use."
"We get a quick response in case any component defaults. We have seen the benefits mostly."
"The price of this solution is good."
"The FlexClone feature is the solution's most valuable aspect."
"The solution offers very good reliable systems and storage for our clients."
"The servers are fast and affordable."
"One of the most valuable features of Lenovo ThinkSystem DM Series is the snapshot feature."
"It has been a perfect fit for the workload that our customer is doing."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"The most valuable feature of Lenovo ThinkSystem DM Series is its capability to tier to the cloud, such as Microsoft Azure or Amazon AWS. Additionally, the integration is good and they are user-friendly."
 

Cons

"In terms of what needs improvement, the dashboard and management could be simplified."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"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."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"I'd like to see the product implement active replication for vehicles such as VMware."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"The deployment took a little longer."
"I would like to see the next generation all-flash, which could be combined."
"Could have a more stable, lighter Metro and better logging system."
"Its data replication features work slowly for nodes."
"The product must improve the local technical support in China."
"Based on what we were quoted, the stated capacity was not a true reflection of the actual capacity."
"Its storage capacity could be better."
"The solution needs to improve the compression side of the application."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"It takes a very long time to enter the management console, as well as to restart the system, and these are things that should be improved."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"The licensing model needs to be revisited. It needs to be simplified."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"This is an expensive solution."
"The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features."
 

Pricing and Cost Advice

"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."
"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."
"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 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."
"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."
"As far as the licensing costs, everything is included in the license."
"The product is expensive."
"Overall, the solution's pricing was cheaper."
"The product is cheap."
"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."
"We pay a monthly licensing fee for this solution. The price could be less expensive."
"Pricing is very fair."
"Huawei OceanStor is priced very well but is a bit complicated."
"The price of Huawei OceanStor should be less expensive. It is expensive at the moment."
"The solution's pricing is similar to Dell and HPE."
"The solution is highly-priced."
"Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."
"The price of the Lenovo ThinkSystem DM Series is good."
