Featured Reviews

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.
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.

Offers high performance and dependable support for fast storage needs
The most valuable feature of IBM FlashSystem ( /products/ibm-flashsystem-reviews ) is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"The solution’s overall security is good."
"It is very easy to use."
"The customer support is helpful."
"Two things really stand out for me. First, there's group cloning, which is very nice. It simplifies managing multiple clones across the group. Second, Huawei's multi-controller architecture with load balancing is a good part."
"Huawei OceanStor Dorado is fast and has significantly improved data storage efficiency."
"It is a scalable solution."
"The solution is scalable."
"The most valuable feature of this solution is the overall simplicity."
"The speed of the unit is its best feature. It performs very well."
"I like most of the features. Its speed, performance, and availability are valuable. We are implementing the data reduction technology the most."
"IBM FlashSystem is the best solution for storage virtualization."
"The valuable feature is autoscalling."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"The valuable features for us are the extra add-ons, such as the FIM provisioning, the compression, the disaster recovery capabilities, and the storage pooling functions."
"The solution is very easy to configure and use."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
 

Cons

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"The software layer has to improve."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"The tool's portfolio is minimal. It is expensive."
"An area of this product that has room for improvement is the NAS capability."
"Huawei OceanStor Dorado could improve the integration, there have been some compatibility issues with some operating system functions."
"The technology and the features need improvement."
"The product should be better aligned with the virtual environments"
"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."
"It should have easy connectivity with the AIX, however, I've found that with AIX, it has some issues and due to this, we need to remove the exact fiber card sometimes and then plug it in again so that it can connect with the AIX systems."
"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."
"The marketing could be improved."
"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."
"The Data Reduction Pools (DRP) support could be better."
"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"The installation is not easy. You need to have extensive knowledge to handle it."
"The solution's infrastructure technology level could be PCI Express 5 instead of PCI Express 4 for the next version."
"The deduplication technology in IBM FlashSystem needs significant improvement."
"The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general."
 

Pricing and Cost Advice

"Given its price, Pure is not the first option."
"The product is expensive."
"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."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"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."
"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."
"In price comparisons with alternative products, it stands out as a more cost-effective option."
"It stands out as the fastest purpose-built storage solution available on the market, and the pricing is highly competitive and excellent."
"There are some costs in addition to the standard licensing fees, depending on the requirements."
"Huawei OceanStor Dorado has a competitive price compared to other solutions."
"The price of the solution is competitive compared to others, such as Dell EMC and Hitachi. I believe the reason they are providing a discount is they want to increase their penetration into the market."
"You need to pay for the license."
"The tool is cost-efficient."
"The pricing is reasonable."
"The total storage capacity vs price is still quite high for the IBM Flash Array."
"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."
"I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten."
"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."
"The pricing is competitive in our country."
"I find the pricing of the solution to be very reasonable."
