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.
TOLGA ALNIAK - PeerSpot reviewer
Offers ransomware protection for files stored on servers
Data processing is the most important feature. We are using Huawei OceanStor Dorado, which employs SSD storage on the hardware side. No reported performance issues or improvements are required for our systems because all of the systems run on memory on the host side. The Oracle data and Oracle virtual machines also operate from memory. Additionally, we use Oracle for patching systems, with all data residing in memory. There is some latency during backup times, typically at night, but this is acceptable for us. These latencies occur outside of office hours, so they do not impact our operations during normal times when there is no noticeable latency.

Quotes from Members

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

Pros

"Technical support has been helpful and responsive."
"The initial setup was extremely simple and straightforward."
"The solution is scalable."
"The most valuable feature of this solution is reliability."
"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."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"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 database workloads are pretty fast because I frequently move data from here to there."
"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."
"There are also DR and data protection functions that we found in the new Unity, now that we are stepping up from VNX and other storage appliances, that we've started implementing."
"They've integrated NAS and SAN pretty well. It made replication very simple. Because one of our systems has a lot of LANs, for it to replicate we have Consistency Groups in there. That's something that is really helpful, making sure that everything is working not just for replication but for backups as well."
"All-flash performance, Snapshotting capabilities and replication are all valuable features."
"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."
"It is completely reliable. The plugins for it are quite mature. I don't really have any issues with the interactions with vSphere, they all work as intended."
"The setup and installation procedures are easy."
"It's easy to use, easy to manage, easy to troubleshoot, and the process support is good."
"Has good capacity, is effective and easy to manage."
"The customer support is helpful."
"The performance is good."
"The most valuable feature for me is that it deduces better, whereby it can be assigned six times the usable capacity, depending on the nature of the data."
"The deduplication features and the graphical user interface (GUI) of the solution are the most valuable to me."
"We can use Huawei OceanStor Dorado capacity storage for many different purposes."
"There are plenty of features available in this solution."
"The initial setup is straightforward. Deployment takes about a day."
 

Cons

"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."
"The tool's pricing is higher than competitors."
"There are some challenges with data encryption and reduction."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"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."
"The software layer has to improve."
"Adding some functions to the product would be beneficial."
"I would like the device to have the ability to pull down its own firmware. That would be a great thing."
"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."
"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."
"I miss storage groups. Now, if I have to add a LUN to a cluster, multiple host, I have to know which host is in that cluster. I have to write it down and that makes it hard. In VNX and earlier, I could simply put a LUN on a storage group and every host in the group had the LUN. This lack bothers me a lot because it takes a lot of time and mistakes are made. Sometimes, a Hyper-V host gets a VMware LUN and vice-versa. Not good."
"Scalability of this solution could be improved."
"Maybe deduplication would be something that would be better to have. Also, it's a fairly new management interface, so work is still being done on that. But compared to other vendors and previous EMC storage, the Unity is really good."
"It would be better if there were more integrations."
"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."
"Huawei OceanStor Dorado could improve the integration, there have been some compatibility issues with some operating system functions."
"The data compression and deduplication ratio of Huawei OceanStor Dorado is not as good as other solutions, such as EMC and Pure Storage. It is important when looking at capacity effectiveness."
"From the customer's point of view, Huawei OceanStor Dorado is expensive."
"The initial setup was very complex."
"The price must be improved."
"Huawei OceanStor Dorado's biggest weakness is its lack of cloud integration."
"The localization problem needs to be improved."
"They should add a feature to the platform to help us manage storage communication with one of the vendors."
 

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 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 product is expensive."
"We pay approximately $50,000 USD per year in licensing fees."
"With VMware, we pay $300,000 annually."
"Our licensing fees are $500,000+ USD."
"As far as the licensing costs, everything is included in the license."
"The solution is very expensive."
"Pricing for this product is manageable, though slightly higher than comparable products."
"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise. Huawei and Lenovo are very price competitive. Looking at the price point for a country like Sri Lanka, where we have a very low economy, I think you need to look at a pricing mechanism that is a bit more flexible."
"Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""
"From an ROI perspective, I'll put it this way: When we've tried to buy other SANs, the Unity ROI makes it impossible to buy them. So usually, the only time we buy another SAN is when the ROI isn't a factor, because Unity can't do the job. From an ROI perspective, it's great because it beats everything else out. We've tried to look at other options but, at the end of the day, when you price it out, the Unity wins."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"Most licenses for the solution are free but upgrades are available when adding additional software or storage."
"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."
"Huawei has very good pricing. They have some promotions that can be taken advantage of at certain times of the year, such as the end of December. They are providing aggressive pricing. In the Pakistan market, they are ready to beat any vendor in Pakistan because they want to grab the market."
"The price of the solution is reasonable. There is not a vendor that offers an All-Flash Storage Array at the price of Huawei OceanStor Dorado. The other solutions are approximately 50% higher."
"The price of the solution is competitive compared to others, such as Dell EMC and Hitachi. I believe the reason they are providing a discount is they want to increase their penetration into the market."
"There are lots of features included with this solution and some of them require additional licensing, such as creating high availability storage using a cluster."
"This product is not too expensive, and the price is competitive on the market."
"There are some costs in addition to the standard licensing fees, depending on the requirements."
"We usually recommend our customers choose advanced licensing and enterprise companies are more inclined to choose this solution because it is more cost-effective than competitors."
"It is an expensive solution."
