The focus of the Sun Journal, Web Edition 2, is data centers. The article,
"Data Center Trends," by Steve Campbell discusses server consolidation and
mainframe application rehosting within a framework of TCO.
The economic climate today requires IT managers to rethink infrastructures.
High-end data centers are experienceing trends in consolidating servers and
rehosting mainframe applications to more open flexible systems.
Server consolidation benefits include an increase in resource utilization,
improved performance and manegeability, and more efficient operations
and planning. Costs can be saved in terms of floor space, heating,
power, and maintenance. Complex systems can be simplified and skills of
IT staff can be leveraged across the data center. Consolidating onto
one operating environment also helps avoid recompiling applications.
Rehosting mainframe applications on high-end UNIXR platforms helps
customers take advantage of networked applications that are not written
Companies that feel locked into the high cost of their legacy mainframe
platforms may also want to consider deploying new applications or rehosting
CICS applications on UNIX
systems. SunTM Mainframe
Transaction Processing Software protects mainframe application assets
and provides a mainframe-CICS-compatible software environment on
SolarisTM Operating Environemnt (Solaris OE). Sun Mainframe
Transaction Processing Software demonstrates the ability to support
enterprise applications without extensive rewriting or reengineering of
the original application.
High-end UNIX systems offer many of the same features as mainframes
such as full hardware redundancy and hot CPU upgrades; dynamic system
domains and automatic dynamic reconfiguration to help manage workloads
and resources to meet fluctuating demands; and high-capacity systems
supporting multiple processors in a single, scalable, SMP environment.
IT managers can also take advantage of integrated stacks which decrease
the risk of patching together various system components that need to
run together smoothly in the data center.
An architecture with a common operating system can increase service
levels and decrease costs. Other aspects for IT managers to consider are CPU
capacity and memory, speed of databse processing, and the indirect costs of
The Sun FireTM server product line brings many mainframe features to
Sun Midframe servers. On the high end, Sun continues to innovate with
the recent announcement of the Sun FireTM 15K Server, the largest
computer that Sun has ever built, with a focus on effectively managing
application lifecycle TCO.
