TSS reference architecture with NSS-HA configuration Figure 2.
TSS data paths
Figure 3 and 4 illustrates the typical data paths that the Dell TSS solution supports in a 3 tier
configuration (fast scratch [Dell DT-HSS], primary [Dell NSS], long term). Figure 3 illustrates the HSM
Data Flow, where manual or script assisted data management occurs between the fast scratch tier and
the primary storage tier, while HSM policy driven data management occurs transparently between
primary storage tier and long-term storage tier. Figure 4 illustrates the Archive Data Flow, where data
migration or Archival process is not transparent and requires admin provided interface for retrieval.
NOTE: In both illustrations, the Dell DT-HSS support is limited to manual or automated (via scripting)
migration between “Fast Scratch” and “Primary Storage” tiers and is not part of the TSS HSM or Archive
architecture.
