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.
Brian Ricci - PeerSpot reviewer
It's constantly enhanced and has impressive reliability and data compression
The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal. I hope Dell addresses that. Everything is pricey these days anyway. It is not like the old days of Compellent. We used to be able to see the metrics for our customers. On Compellent, we could look up that customer and see all the metrics. That is not allowed for us now. We cannot do that anymore. I have to be explicitly allowed by the customer to do that, and some companies' security does not allow that.

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

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The initial setup was extremely simple and straightforward."
"The database workloads are pretty fast because I frequently move data from here to there."
"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."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"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 most valuable features of this solution are its ease of use and performance."
"PowerStore is easy to use, powerful, reliable, and highly customizable to customer's needs."
"The most important aspect of Dell PowerStore in comparison to any other platform is that it helps us save costs while giving more value per GB per dollar spent. It provides an industry-leading DRR ratio."
"The solution is very easy to implement."
"I have seen a return on investment with Dell PowerStore as it does what we wanted it to do. It gives me peace of mind."
"The most valuable features of Dell PowerStore are the resilience, scalability, flexibility of expansion, and ease of managing the entire solution including the servers and storage."
"The support is very good."
"The most valuable aspects of Dell PowerStore are the promising roadmap, and the interesting features to come."
"The most valuable feature of Dell PowerStore is Metro Volumes. It allowed us to remove our current Recovery Point/Broadcom VMware SRM licenses, which cost a fortune, resulting in significant cost savings."
"OceanStor can be used as NAS and SAN storage at the same time, with both file and block features in the same box."
"Stability: The product is designed to have always HA (High Availability) with redundant network and processors."
"This is a stable storage system."
"Huawei OceanStor is stable and reliable for storage solutions."
"Huawei is much cheaper compared to Dell, offering a competitive price that makes companies consider their options."
"The most valuable feature is the availability."
"The setup and the price are the most valuable and not the features related."
"Generally stable with good technical support."
 

Cons

"It is on the expensive side."
"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've seen that when we create a POD in synchronous mode, it increases the latency."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"The UI for this solution needs to be improved."
"Maybe the price can be reduced since the solution is very expensive."
"I'd like to see the product implement active replication for vehicles such as VMware."
"Monitoring is an area of concern in the product where improvements are required."
"AI will be a challenge and we must manage different kinds of data with more performance and security."
"If I could improve anything about Dell PowerStore, there are a couple of in-the-weeds features that I would want to see, such as the size of snapshots to know when we can expire some of them."
"The data resiliency and cybersecurity features of Dell PowerStore are just normal and would be considered medium; we need additional components such as cybersecurity vault for increased resilience."
"Sometimes, you have to go back and forth with the technical support team, where they want you to do something you've already done."
"We have not seen an ROI and it would be good to have an ROI calculator made available by Dell."
"Dell PowerStore can improve the integration with VMware."
"It would be helpful for us to have support for the S3 protocol because our main competitor has the S3 protocol in their system."
"Huawei is not that cheap."
"A concern with OceanStor is pricing. However, apart from that, there are no significant limitations or technical issues."
"The upgrading process needs improvement. Deploy it and notify the customers when new versions and stuff comes out. I don't think they're doing that well."
"The administration should be simplified because there are a large number of options that make it too complicated, and the customers can get confused."
"Huawei currently lacks a solution for high-performance AI, unlike other companies like DDN, WekaIO, or IBM BlueStore."
"The solution could improve by having better integration."
"The tool's performance is slow for DBs. We plan to move from Huawei OceanStor to Pure Storage. Its customer service is not good."
"The main concern is regarding the usability of the data storage."
 

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."
"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."
"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."
"As far as the licensing costs, everything is included in the license."
"We pay approximately $50,000 USD per year in licensing fees."
"Given its price, Pure is not the first option."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The support cost per array is about $20,000 a year for 24/7 support."
"Dell PowerStore has been priced aggressively, especially when compared to other NVMe storage options. It is likely one of the most cost-effective options for organizations seeking a pure NVMe play in terms of pricing."
"It is expensive compared to one of its competitors."
"The rate is always too high. Nobody likes paying for it. I have not seen a client yet who says that the price should be higher. Initially, people look at it, but when they see what the benefits are, it is a no-brainer. We can give them good pricing at the outset."
"Dell PowerStore charges for the hardware warranty every three years. The price will depend on the storage model or how much hardware it has."
"Dealing with the licensing part of the product is very simple, especially considering the fact that we don't have many licenses associated with the tool."
"The licensing for this solution is good and is in the mid-range tier."
"When we compared it with the other solutions, the pricing of PowerStore was equal. The pricing is good."
"The price is not cheap, but it's worth it for the features you get from the storage. If you can afford it, you are probably buying the best solution that you can have for this virtual environment."
"Overall, the solution's pricing was cheaper."
"This product value matches its price."
"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."
"The price of the solution could be less expensive. However, there are not any licensing costs."
"Huawei OceanStor is a cost-effective storage solution."
"Huawei OceanStor is priced very well but is a bit complicated."
"It's roughly affordable."
"The product is cheap."
