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."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"The database workloads are pretty fast because I frequently move data from here to there."
"The solution is scalable."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"I appreciate the performance."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"We have integrated it with vSphere and SQL. There were no costs involved outside of our normal workload licensing, no costs that were specific to the Unity platform."
"It can be simple to deploy, the standup time is quite quick. The interface is quite quick. The terms are simple, intuitive, it's similar what was there in the VNXE before it. It's very simple to navigate and administer from the console."
"It gives me the flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it."
"Ease of use is probably number one, compared to the previous storage that we've had. Easy scalability, easy set up. Compared to everything else, the Unity is, well, you could call it child's play. As long as you know what you're doing storage-wise, Unity is really easy to use."
"For sites that we use it on, it gives us more flexibility and high availability solutions. It is easier to expand the site, if needed."
"The valuable features of Unity include that it's flexible, has a friendly user-interface, and provides good performance."
"The solution is so easy to manage that I forget it is there."
"I like the easy management with the new Unisphere management and the HTML5 interface."
"The solution’s overall security is good."
"The installation and management are very easy."
"The initial setup is straightforward. Deployment takes about a day."
"The customer support is helpful."
"The solution is scalable."
"The product offers good performance."
"The most valuable features of the solution are SmartMigration, HyperReplication, HyperSnap, HyperCopy, HyperClone, SmartPartition, and SmartCache."
"We can use Huawei OceanStor Dorado capacity storage for many different purposes."
 

Cons

"We need better data deduplication."
"The tool's portfolio is minimal. It is expensive."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"In the future, I would like to see integration with enterprise backup systems."
"There are some challenges with data encryption and reduction."
"The tool's pricing is higher than competitors."
"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."
"I would like to see more integration with other products."
"Thick provisioning of LUNs."
"Recently, they released products, sometimes without proper testing, it seems."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products. There could be better integrated and the capacity of the size could be larger."
"Dell Unity XT’s price needs improvement."
"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."
"The price must be improved."
"This solution does not support VMware VVols 2.0."
"The initial setup was very complex."
"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."
"I would really like to see Heterogeneous Storage Virtualization in a future release."
"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."
"One of the key areas that need enhancement pertains to the software procurement process."
"An area of this product that has room for improvement is the NAS capability."
 

Pricing and Cost Advice

"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."
"As far as the licensing costs, everything is included in the license."
"The product is expensive."
"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."
"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."
"With VMware, we pay $300,000 annually."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"Compared to other EMC platforms, Unity is nice because it is all-inclusive, in terms of the licensing model. That's unique for them, compared to other manufacturers. It is beneficial. We could use replication, native, right out-of-the-box."
"It scales, but then you have to buy additional stuff."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"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."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"There are some costs in addition to the standard licensing fees, depending on the requirements."
"Huawei OceanStor Dorado is more affordable than the competitor solutions"
"The pricing is one thing that works for them. I think their pricing is more competitively affordable than these top competitors."
"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."
"The pricing is very competitive."
"It stands out as the fastest purpose-built storage solution available on the market, and the pricing is highly competitive and excellent."
"In price comparisons with alternative products, it stands out as a more cost-effective option."
"I rate the pricing a six on a scale from one to ten, where one is expensive, not cost-effective, and ten is cheap."
