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

"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 solution is very straightforward to set up."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"One of the best features is the support, which is excellent."
"It has benefited my organization because it has reduced time to insights."
"The solution is scalable."
"The most valuable feature of this solution is its ease of use."
"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 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 UI itself is fantastic, and the ease of administration is far better than Unisphere or Navisphere ever were. It's very easy to manage. The fact that it has built-in APIs means our automation people can help us automate a lot of tasks, and that has been helpful. And, of course, it's really fast. Obviously, that doesn't hurt anything at all."
"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."
"There has been no downtime. It has built-in redundancy upon redundancy."
"It's very reliable. I have not had an issue with Dell EMC Unity."
"The hardware itself, it differs from Compellent and differs from the VNX before it. It doesn't have a separate file harbor that goes with it, there are no separate NAS heads. It's 2U, you have file and block storage, so you get a quite a lot of services for a small footprint."
"The technical support is very professional and provides quick responses."
"Integration is easy with this product."
"Huawei OceanStor is designed with built-in high availability features, such as fault tolerance, ensuring consistent data access and minimizing downtime."
"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."
"The most valuable features of Huawei OceanStor are the dashboards, bandwidth, and data performance."
"If your virtual machine that resides on it completely fills the storage space, thanks to it's built-in function of all-zero data space reclamation, you just have to ask to System Engineer to run a zero-free on hosts (thin provisioned) and you will get more space instantaneously."
"The most valuable feature is the availability."
"Excellent and efficient support, and the product is a good price."
"The solution has improved our organization by speeding up our operations."
"The solution is scalable."
 

Cons

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"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."
"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."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"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."
"In terms of what needs improvement, the dashboard and management could be simplified."
"In the dashboard there could be notification of duplicate files and the like, so we don't have to rely on Windows to do that."
"I would like to see more compression and deduplication added to the solution. Today, our compression is about 2:1 and other solutions give us about 4:1 or 5:1."
"We would like to see the concept of Storage Groups brought back to this product line."
"We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that."
"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."
"The EMC VNX Virtual Data Mover (VDM) software needs more improvement."
"In terms of what could be improved, I would say its capacity and its connection."
"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."
"I would like to see more iterations and direct integration with other solutions."
"The deployment took a little longer."
"Based on what we were quoted, the stated capacity was not a true reflection of the actual capacity."
"Technical support could be more helpful."
"The tool's performance is slow for DBs. We plan to move from Huawei OceanStor to Pure Storage. Its customer service is not good."
"I would like to see more integration features with different platforms."
"Integration with mainstream solution technologies could be better."
"Could have a more stable, lighter Metro and better logging system."
 

Pricing and Cost Advice

"Our licensing fees are $500,000+ USD."
"As far as the licensing costs, everything is included in the license."
"Given its price, Pure is not the first option."
"The licensing is on a yearly basis."
"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."
"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 support cost per array is about $20,000 a year for 24/7 support."
"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."
"We checked both HP and Dell and we determined that Dell EMC was a better option."
"The solution is extremely functional for the price that we pay for it. It is worth the investment."
"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."
"From a pricing perspective, this solution is comparable to others on the market."
"The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."
"This solution is a good price for what you get."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"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."
"We pay a monthly licensing fee for this solution. The price could be less expensive."
"Its price is affordable."
"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."
"Huawei OceanStor is a cost-effective storage solution."
"The price of the license is quite low, so it's not something special or expensive."
"Overall, the solution's pricing was cheaper."
"Huawei OceanStor is priced very well but is a bit complicated."
"The pricing depends on the features the customer wants, such as storage, RAM, and processors, but in general, Huawei is much cheaper compared to Dell and Cisco."
