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.

Quotes from Members

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

Pros

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

"I would rate Pure Storage FlashBlade a ten out of ten."

"The initial setup is pretty quick."

"The most valuable feature of this solution is performance."

"We have seen a reduction in the total cost of ownership by around 20%."

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

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

"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 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."

"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."

"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."

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

Cons

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

"I have not seen ROI."

"The documentational aspect of FlashBlade needs improvement."

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"The feature that we're waiting on is better integration with the cell services."

"The features provided for SMB customers are limited."

"It's on the expensive side, as expected for a niche product."

More Pure Storage FlashBlade cons

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

"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."

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

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

Pricing and Cost Advice

"Our customers have seen a reduction in TCO."

"The product is very expensive."

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

"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 is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

"The price is a little high."

"I feel that the price could always be lowered."

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