• Innovative Virtual LAN support to establish multiple high speed TCP/IP communication
connections between partitions without additional communication hardware
• Multiple OS/400 versions (V4R4, V4R5, and V5R1) within a partitioned environment
on appropriate systems
– 8xx SStar: Primary V5R1, secondary V4R5 or V5R1
– 8xx iStar: Primary and secondary V4R5 or V5R1
– 6xx, Sx0, and 7xx servers: Primary and secondary V4R4, V4R5, or V5R1
• Linux is now supported in a logical partition
• Virtual LAN support establishes multiple high speed TCP/IP communication connections
between partitions. Additional communication hardware is not required.
Capabilities applying to 270 and 8xx models and V5R1 only include:
• Granularity of processor movement reduced to 1% of each processor
• Support for up to four OS/400 V5R1 partitions per processor, up to a maximum of 32
partitions.
• Extension of partitioning support to select iSeries Model 270 and 820 uniprocessors
• Operations Navigator support to create and manage partitions including scheduled
movement of resources
• OptiConnect is supported over HSL
Creating and managing secondary partitions is performed from the primary partition.
Releases supported in a logical partition are shown in this table.
