A 24-rack #NetApp system has been replaced with a single #PureStorage #FlashBlade product at a customer site. Two Pure Storage staffers have tweeted that the replaced system spanned 1,008 rack units, was fitted with 13,000 disk drives. A Pure Storage source said that the replaced system was from NetApp. FlashBlade is Pure’s flash-based system for fast access to unstructured data, and accompanies its FlashArray, which provides primary data storage. The intention is for FlashBlade storage to be used for Big Data analytics-type applications, and, we understand, the traditional scale-out filer apps that may have used Isilon and NetApp filers or similar products previously. The scale-out FlashBlade system sits in a 4U cabinet with 15 storage blades inside it. Each blade has up to 52TB of on-board capacity, meaning 780TB of max raw capacity, which after losing about one third for N+2 erasure coding, and amplifying with 3:1 data reduction, is 1.5PB. The customer’s FlashBlade system costs millions of dollars less than and out-performs the NetApp array, we’re told. Partly this is because flash is faster than disk but also because the FlashBlade IO load is automatically processed across all blades. In contrast, in a FAS cluster the IO of a volume can only be processed by a single controller.
