Host-Based RAID Controllers: An Uncertain Future

Published: 17 April 2000

ID: G0087370

Analyst(s): Roger W. Cox


Host-based RAID controllers have been the historic cornerstone for fault-tolerant storage in the general-purpose Intel-based server market. This Perspective examines the future of host-based RAID controllers, including the profound impact of new storage architectures -- network attached storage (NAS) and storage area networks (SANs) -- and new forms of host-based RAID controller technology -- RAID-on-the-motherboard (ROMB) and RAID-on-a-chip (ROC) -- on the traditional host-based RAID controller add-in card market.
