By default for each 1TB of data, 8MB is allocated for metadata. The data and metadata is stored on the physical storage devices (RSDs) and both are protected using mirroring (2N). Because metadata is this lightweight, all of the metadata of all of the online VSDs is cached in DRAM.

VSD = Virtual SCRIBE Device
RSD = Real SCRIBE Device
