Symmetric Active/Active Controller

Optimizing Dynamic Workloads

Application Brief

By Patrick Allaire and Mark Adams

October 2008

Executive Summary

Storage administrators, already confronted with unprecedented data growth, now encounter

a new imperative: to discover and exploit efficiencies at every level, from storage

administration to data flow, in order to keep to an absolute minimum the amount of new

staff, hardware and software required to manage ever increasing volumes of data. The

Hitachi Adaptable Modular Storage 2000 family addresses the needs of growing businesses

by supporting operational efficiency at a high level and providing throughput and scalability

at every stage of growth.

Within the Adaptable Modular St architecture of the Hitachi orage 2000 family, the innovative

Dynamic Load Balancing Controller plays a pivotal role by automatically and dynamically

managing storage loads and dramatically simplifying storage administration, while providing

the superior levels of performance that growing businesses require. Its symmetric

active/active controller technology offers something unique: by decoupling the host system

from speciﬁc LUN assignments, I/O processes can be automatically routed along the most

efficient path, for unprecedented flexibility and optimized SAN performance.

This paper examines the complexity and management challenges presented by the current

storage landscape, the explosive growth of data storage requirements and what it all means

to businesses. In addition, the paper reviews various controller technologies as well as

issues faced by administrators working to optimize dynamic workloads. Finally, it provides a

detailed discussion of the Hitachi Dynamic Load Balancing Controller — a symmetric

active/active implementation — and its ability to simplify storage management, improve

efficiency and performance, and provide the capabilities required for future growth.
