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

"Everything, especially the VMs inside, is pretty fast."
"The most valuable feature of this solution is reliability."
"The latency is good."
"The solution is very straightforward to set up."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"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 initial setup was extremely simple and straightforward."
"The most valuable feature of this solution is its ease of use."
"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"
"It is lightning fast, low on power and heat, and has a small footprint with great performance."
"It has good performance."
"Integration is easy with this product."
"It is easy to manage overall. It is all web-based. It has a an easy, nice dashboard. I receive emails if there are issues. When there are any updates, I receive emails. I can either do them on my own, but normally I schedule them with Dell EMC and they remote in, then it's done."
"The most valuable feature is the fast cache with functionality rewrite."
"It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about."
"The ease of management and “user-friendly” management environment (GUI)."
"Huawei OceanStor has the capability of SSDs, high-performance disks, and higher disk support."
"The solution is easy to scale as needed."
"Stability: The product is designed to have always HA (High Availability) with redundant network and processors."
"Huawei is much cheaper compared to Dell, offering a competitive price that makes companies consider their options."
"Huawei OceanStor utilizes a proprietary technology known as RAID 2.0. This technology sets it apart from conventional storage solutions. RAID 2.0 offers advantages over traditional configurations. OceanStor's user interface is very simple and easy to use, featuring a graphical interface that enables quick and error-free setup of the storage system. This interface ensures that users can configure the storage efficiently and without mistakes."
"OceanStor can be used as NAS and SAN storage at the same time, with both file and block features in the same box."
"Huawei OceanStor offers good IOPS and is reliable and energy-efficient."
"The most valuable feature is the availability."
 

Cons

"In the future, I would like to see integration with enterprise backup systems."
"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."
"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."
"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."
"The software layer has to improve."
"The tool's pricing is higher than competitors."
"I would like to see replication and DR features in the next release of this solution."
"The pricing is a bit high. We'd like it to come down."
"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."
"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."
"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
"I rate the scalability of Dell Unity XT a nine out of ten."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"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."
"I would like to see more integration features with different platforms."
"The main concern is regarding the usability of the data storage."
"The solution’s reporting could be improved."
"They should introduce a feature to Huawei OceanStor similar to a storage controller, allowing for seamless integration of additional storage modules."
"The solution needs to improve the compression side of the application."
"The management is not a good feature in all of Huawei products. It's not easy or simple. Huawei has some problems with management and handling storage information from one interface."
"The price could be better. It's not good for the Brazilian market."
 

Pricing and Cost Advice

"The licensing is on a yearly basis."
"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."
"The product is expensive."
"Our licensing fees are $500,000+ USD."
"As far as the licensing costs, everything is included in the license."
"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."
"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."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."
"Go with the virtual appliance versus the hardware."
"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 price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"With the large Unity that we bought, it has saved us about one and a half rack space. That's our return on investment on our flash array. We also need less Fibre Channel connectivity."
"It's roughly affordable."
"The price of the license is quite low, so it's not something special or expensive."
"Huawei OceanStor is a cost-effective storage solution."
"Huawei's prices are very good compared to those of its competitors."
"We pay a monthly licensing fee for this solution. The price could be less expensive."
"Its price is affordable."
"The product is cheap."
"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."
