High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

Enables seamless file distribution while benefiting from scalability but could use simplified implementation

IBM Storage Fusion is used in telecoms. It is a file center that receives and shares files. It is also used for writing the CDR zone on the storage, since it offers a cost-effective solution for large-scale storage needs in a telecom setup The deployment of Storage Fusion has been new for us in…

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 include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."

"We can capacity plan at a greater level than we used to."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

More Pure Storage FlashBlade pros

"Fusion provides the ability to install the secret server and distribute files; it serves as a black box where tickets are opened only if issues arise, reducing frequent upgrade problems."

"The speed of the product is quite a bit better in performance than the previous peer environment we were running on, and it seems to have a better feature set."

"The Evergreen program is excellent, and the pricing is quite reasonable. My friends who work there are doing very well and consistently achieving strong results. Like any company, they experience occasional downturns but perform impressively overall."

"The speed of the product is quite a bit better in performance than the previous environment we were running on, and it seems to have a better feature set."

"Pure Storage has the highest Net Promoter Score in the market."

"We have snapshots. We put snapshots on disks, and we can save information. In the case of ransomware, everything is in the snapshot. We have a snapshot lock on it, so it's safe."

Cons

"Its configuration should be easier."

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"Pure Storage FlashBlade should improve on more cloud integration."

"There could be improvements in public cloud integration."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

"The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top."

More Pure Storage FlashBlade cons

"The implementation is complex, especially when using custom servers."

"I'm not sure if any improvements are needed."

"To me, I think it's a little expensive. Then again, you get what you pay for."

"Many customers report that the starting price is quite high. However, the overall total cost of ownership can be reduced over time due to features like the Evergreen architecture, which allows savings through less management and environmental benefits."

"It would be nice to have support in Swedish."

"The only potential drawback is that Pure Storage might be overkill if you don't need microsecond response times."

Pricing and Cost Advice

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"The price could be cheaper."

"I rate the tool's pricing a seven to eight out of ten."

"The price is a little high."

"Our customers have seen a reduction in TCO."

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"The pricing for FlashBlade is between cheap and moderate."
