Pillar hosted by KB

...

The KB pillar is characterized by it's distributed architecture.

The pillar consists of several nodes, each consisting of a Windows server with directly attached storage. This makes the KB pillar well suited for processor intensive calculations, but for optimal performance, a highly parallel aproach must also be taken in the design of the pillar software, and the implementation of checksumming and mass processing will require some thought for optimal distribution and recollection of data.

KB Pillar limitations
