iSeries Architecture: Fundamental Strength of the iSeries22 iSeries HandbookEnhancements for the new Integrated xSeries Server include support for up to 32 servers onselected iSeries models. See “iSeries Integration with Windows Server (Base 5722-SS1 as5722-WSV)” on page 502.Benefits of Server Consolidation on the iSeries ServerServer consolidation on the iSeries allows you to:• Consolidate PC server hardware and operations so you can run up to 32 Windows NTservers in a single server.• Increase business recovery protection with high-speed backup of the combined iSeriesserver and Windows NT systems.• Improve server uptime and error recovery using highly reliable iSeries disk drives withRAID-5 and mirroring options. Use a spare Integrated xSeries Server to replace afailed server without reloading Windows NT.• Maximize I/O investments by balancing iSeries servers and Windows NT diskresources from a single pool. Switch user data disks between servers. Share theiSeries tape and CD-ROM drives.Logical Partitioning (LPAR)Logical Partitioning enhances the role of the iSeries as a consolidated server. LPAR is ofvalue to customers who need server consolidation, business unit consolidation, mixedproduction, and a test environment, as well as integrated clusters. With LPAR, companieshave both the power and flexibility to address multiple system requirements in a singlemachine.LPAR lets you run multiple independent OS/400 instances or partitions (each with its ownprocessors, memory, and disks) in an n-way symmetric multiprocessing AS/400e 6xx, Sxx, or7xx and uni or n-way on 270 and 8xx models. Address multiple system requirements in asingle machine to achieve server consolidation, business unit consolidation, mixedproduction/test environments, and integrated clusters.Partitions have different system names and may have a different primary or secondarynational language, or they may operate using different time zones. Each partition's systemvalues can be set independently. This flexibility is ideal for banks and other multinationalcompanies to centralize operations in a single location, yet retain the national characteristicsof each system. Logical partitions are ideal for companies to run mixed interactive and serverworkloads on a single iSeries. Logical partitions allow the interactive performance of aniSeries to be flexibly allocated between partitions.
