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

"The most valuable feature of this solution is reliability."
"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 database workloads are pretty fast because I frequently move data from here to there."
"What I really like about this program, is that it is easy to use and easy to configurate."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"The fact that it's hybrid is the most valuable feature. We have the SSD so we put our SharePoint on there and some of the stuff that requires a little more speed. For SharePoint, we want the pages to respond a little more quickly. And it's nice to be able to use the slower storage for stuff that we don't need as quickly, like file servers."
"The most valuable feature is the integration with vCenter."
"I like the integration into VirtualCenter. I used to have to add LUNs manually, then scan them in and format them. It does that all for you, all in one, immediate deployment of LUNs."
"We use the solution for site recovery manager, DR, and endpoint penetration."
"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."
"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."
"It is a workhorse and will run even demanding workloads."
"It is lightning fast, low on power and heat, and has a small footprint with great performance."
"The most valuable feature of this solution is the price to performance ratio."
"Huawei has more features than other vendors. It integrates well with security management solutions, though not directly with databases."
"The performance is good."
"Huawei OceanStor Dorado is fast and has significantly improved data storage efficiency."
"Huawei includes features for file servers and file services. It offers ransomware protection for files stored on servers. However, it does not support blocking websites."
"This is a stable product that we can use for DR in production."
"The initial setup is very straightforward."
"The fast performance and reasonable pricing of Huawei OceanStor Dorado are the main reasons we sell them."
 

Cons

"The UI for this solution needs to be improved."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"In the future, I would like to see integration with enterprise backup systems."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"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."
"Software updates have to be downloaded to the root of the device. This pushes the available space to 95% utilization."
"Data replication needs improvement as the future roadmap for RecoverPoint appliance is not there."
"Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature."
"I would like the device to have the ability to pull down its own firmware. That would be a great thing."
"It could always use native replication. Then I could get rid of RecoverPoint."
"Ordering is easy, but the processing site and working with those companies was difficult."
"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."
"Our customers are mostly happy with Unity except for the price. We primarily sell to enterprise companies because small companies cannot afford it."
"Engineers with two to three years of experience with Huawei will find that Huawei OceanStor Dorado is a bit complicated to use compared to other Huawei storages."
"The speeds of the disks themselves need to be faster. The disks are not flash. When we opened our hard drive from the inclusion, I saw a converter, and it's not entirely flash."
"An area of this product that has room for improvement is the NAS capability."
"Huawei OceanStor Dorado could improve by having a multi-tier cloud option and additional protocols"
"Difficult integration with third parties."
"Huawei OceanStor Dorado's biggest weakness is its lack of cloud integration."
"I would really like to see Heterogeneous Storage Virtualization in a future release."
"In additional features, it would be easier to do snapshots on a regular basis. So, like, a new feature that would allow you to take snapshots every hour."
 

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"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."
"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 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."
"Our licensing fees are $500,000+ USD."
"The licensing is on a yearly basis."
"Pricing for this product is manageable, though slightly higher than comparable products."
"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."
"Most licenses for the solution are free but upgrades are available when adding additional software or storage."
"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."
"At the end of the day, the licensing cost is key, because every customer has a pain point, that the cost of each piece is high. So if they would bundle everything in a package, that is how the competitors are selling their footprint."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"It scales, but then you have to buy additional stuff."
"The pricing is very competitive."
"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."
"I rate the pricing a six on a scale from one to ten, where one is expensive, not cost-effective, and ten is cheap."
"Huawei OceanStor Dorado is more affordable than the competitor solutions"
"It's not easy to receive an upgrade license of Huawei OceanStor Dorado. It's easy to buy OceanStor with several features, but when you want to add on features later it's not easy. I had some problems."
"Huawei OceanStor Dorado has a competitive price compared to other solutions."
"We saw ROI in terms of both money and time saved. It is worth the price."
"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."
