Eric Black

Solutions Architect at Recovery Point Systems

The ability to leverage multi-tenancy along with immutability is a huge benefit for us

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. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

Quotes from Members

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

Pros

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

"FlashBlade offers low latency, high throughput, and seamless scalability."

"The product is scalable and easy to expand."

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

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."

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

"It's very easy-to-use."

"The main feature I have found to be product replication."

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."

"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."

"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."

Cons

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

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

"I would like to see more monitoring capability included in the next release of this solution."

"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 speed could be improved."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

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

"The documentational aspect of FlashBlade needs improvement."

More Pure Storage FlashBlade cons

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

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

"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."

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

"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."

Pricing and Cost Advice

"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."

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

"We used a reseller for the purchase."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

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

"I understand that it is competitively priced compared to other brands."

"Our customers have seen a reduction in TCO."

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