Storage Industry Overview

3.3 Storage management

“Integration” and “automation” is the future storage management trend

Storage means the movement, placement and acquisition on data based on Physical,

Logical or Virtualization concept; no matter which storage body the data is placed, it

still keeps its availability. In the meantime, it plays a role as the working bridge

between storage system and application software, it also provides an integrated and

automatic storage management solution; meanwhile, it is a smart mechanism which

automatically monitors, reports, integrates, manages and recovers data so that IT

personnel can easily installs, maintains and manages it in the least man power and

in shortest time. Therefore, under the heterogeneous environment system, storage,

network and diversified storage architectures, how to effectively integrate and

provide automatic management functions has become the key design topic of the

current storage software giants.

Traditional management software is included in operation system, however, as the

storage environment becomes more and more complicated in recent years and

storage system functions get stronger, the enterprise storage solution has deviated

the master/slave structure of traditional server, the role plays by storage

management in the whole storage solution has thus become an industry with total

sales up to 10 billions US dollars; IDC forecasts that the storage software in between

2001~2005 will have a compound growth rate of 26.1%, storage management

market will have the highest growth rate in all storage sub-systems.

Storage management can be divided into four main functions and types:

1. Data backup and protection

80% of the storage management software provides such functions.

z Hierarchy Storage Management (HSM)/ Archive

z Backup/Restore

2. High availability

When scheduled or non-scheduled system down has occurred, data hook-up and recovery

capability is guaranteed.

z Backup at different place/failure takeover

z Clustering management

3. System and organization management

storage subsystem, related storage management services, etc. through the use of
