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.

Manages large data sets efficiently with hybrid cloud integration
My organization is quite large, with about 30,000 employees. The growth has been substantial in areas such as radiology and genomics. One of the best features we've utilized recently is offload to cloud pools due to capacity constraints on-premise. We didn't want to expand Dell PowerScale (Isilon) straight away, so we utilized cloud pools to offload some data to Azure. That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.
