NIRD TS vs NIRD DL
NIRD consists of two separate storage systems, namely Tiered Storage (NIRD TS) and Data Lake (NIRD DL).
NIRD TS has several tiers spanned by single filesystem and designed for performance and used mainly for active project data.
NIRD DL has a flat structure, designed mainly for less active data, sharing data across multiple projects, and interfacing with external storages.
Both are based on IBM Elastic Storage System.
