Introduction
The Data Storage Subsystem
– – – – – – Channel Adapters (CHA/FED) Cache Memory Control (Shared) Memory Cache Switch Disk Adapters (DKA/BED) Hard Disk Drives (HDDs)
Host Server with one or more HBAs Universal Storage Platform/Network Storage Controller
• The subsystem is required to present disk space, as LUNs to many servers • The hardware must provide data resilience and be fault tolerant • It also needs to be fast
