The legend label “Mixed Files” indicates a save of many files of mixed sizes - equivalent to the save of
the Windows system file disk. “Large files” indicates a save of many large files - in this case many
100MB files.

17.8 Summary
The iSCSI host bus adapter, Integrated xSeries Server and Integrated xSeries Adapter provides scalable
integration for full file, print and application servers running Windows 2000 Server, Windows Server
2003 or with Intel Linux editions. They provide flexible consolidation of System i solutions and
Windows or Linux services, in combination with improved hardware control, availability, and reduced
maintenance costs. These solutions perform well as a file or application server for popular applications,
using the System i host disks, tape and optical resources. The iSCSI HBA addition in V5R4 increases
Integrated server configuration flexibility and performance scalability. As part of the preparation for
integrated server installations, care should be taken to estimate the expected workload of the Windows or
Linux server applications and reserve sufficient i5/OS resources for the integrated servers.
