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

"The solution uses newer technology for deduplication and compression."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"It has benefited my organization because it has reduced time to insights."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"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."
"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."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"Overall stability is very good. It is a very stable solution."
"The solution is so easy to manage that I forget it is there."
"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."
"Dell Unity XT offers data integration features."
"All-flash performance, Snapshotting capabilities and replication are all valuable features."
"It's easy to use, easy to manage, easy to troubleshoot, and the process support is good."
"All-flash is a game changer. If you need performance, simple operations, and you plan to use it with VMware, it is a good choice."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"It is scalable. Customers are going more into distributed architecture, so the Unity definitely has a scalable architecture built into that."
"The integrated Huawei Flash technology within OceanStor Dorado stands out as one of the most valuable features."
"We can use Huawei OceanStor Dorado capacity storage for many different purposes."
"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 product has the best compression and encryption features. The most valuable features I have found in the tool are its performance and cost-effectiveness. While Huawei OceanStor Dorado may not always be chosen for its features compared to other brands like Dell, HPE, etc., it is often selected due to its affordability. Customers opt for Huawei OceanStor Dorado primarily because it offers similar performance features as other brands at a lower cost."
"The support team is responsive and effective in addressing any issues that arise."
"The most valuable features of the solution are SmartMigration, HyperReplication, HyperSnap, HyperCopy, HyperClone, SmartPartition, and SmartCache."
"This is a stable product that we can use for DR in production."
 

Cons

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"The tool's pricing is higher than competitors."
"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."
"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 tool's portfolio is minimal. It is expensive."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"We'd like to see a cheaper version of an all-flash array in that footprint."
"The user interface could be improved. The Dell Compellent user interface is fantastic, but the Unity user interface is, in comparison, pretty lousy. It's functional, and I can do what I need, but the Dell Compellent user interface is so much more intuitive and user-friendly."
"Issues with slow responses from the support team."
"I would like to see a more seamless virtual box integration with the physical box which can replicate, because the setup of the replication is very difficult right now."
"I would like the UI to look better."
"In some countries, spare part availability is an issue for us."
"We've also encountered an issue when it comes to migrating to compressed LANs on the Unity, and during the Storage vMotion. It appears that the compression algorithm is overwhelmed, and when it becomes overwhelmed it just stops compressing and writes the raw data to the destination. We later copied internally another Storage vMotion to another compressed LAN and achieved much higher compressions on that internal copy. It would be really nice if there was a way to automatically throttle, as a part of a Storage vMotion, to say, "I want to gain the maximum benefits from the compression algorithm, so throttle back the Storage vMotion to implement 100 percent compression.""
"Stability is the problem. We've had stability issues with it. We've had problems with the iSCSI interface. We've had it for two years now and for two years we've had problems where a service processor will drop, we'll lose connectivity to LUNs, we'll lose connectivity to the storage, issues like that. No matter how we've tried to chase it down, everybody just points fingers at each other. The only thing that changed in our environment was that the Unity solution was installed."
"The product's current pricing model involves over 12 different licenses, which can be complex. Simplifying the process would enhance the overall user experience."
"An area of this product that has room for improvement is the NAS capability."
"There could be local support services available for the platform. Additionally, they should provide a bundled license, including all protection and encryption rules."
"They should add a feature to the platform to help us manage storage communication with one of the vendors."
"There are some limitations to this product because they do not have unified storage."
"This solution can improve by providing easier migrations and better Metro features."
"This solution does not support VMware VVols 2.0."
"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

"The licensing is on a yearly basis."
"Our licensing fees are $500,000+ USD."
"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"Given its price, Pure is not the first option."
"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 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."
"I liked the price point when we purchased it."
"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"Most licenses for the solution are free but upgrades are available when adding additional software or storage."
"It scales, but then you have to buy additional stuff."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"We purchased a five-year warranty."
"Pricing is as high as it has ever been for EMC."
"Huawei OceanStor Dorado is more affordable than the competitor solutions"
"Huawei OceanStor Dorado has a competitive price compared to other solutions."
"The pricing is one thing that works for them. I think their pricing is more competitively affordable than these top competitors."
"It is an expensive solution."
"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."
"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."
"The solution's licensing structure needs improvement."
"The price of Huawei OceanStor Dorado is very inexpensive, it cost approximately $5 per gigabyte."
