Draft Document for Review October 18, 2004
Multiple operating system support
– i5/OS and OS/400
– Linux
– AIX 5L
– Windows (via Integrated xSeries Server or Integrated xSeries Adapter)
Multiple i5/OS and OS/400 versions within a partitioned environment on
appropriate systems
See the LPAR table on page 544 to understand what operating system
release is supported in the primary and secondary partitions of each iSeries
server.
Virtual OptiConnect emulates external OptiConnect hardware by providing a
virtual bus between logical partitions. To use Virtual OptiConnect, you only
need to purchase OptiConnect for OS/400. Additional hardware is not
required. If multiple paths between partitions are available, OptiConnect
software selects the Virtual OptiConnect path over either a HSL or SPD
OptiConnect external path. An IPL of the affected partitions is not required.
Up to 4064 virtual networks using IEEE 802.1Q VLAN are supported between
partitions on the Models 520, 550, 570 and 595. Virtual Ethernet provides 16
independent high-speed virtual 1Gb Ethernet internal bus-to-bus
communication paths between logical partitions on Models 270, 800, 810,
825, 870, and 890.
Virtual Ethernet supports TCP/IP. Additional communication hardware is not
required.
The enablement and setup of Virtual Ethernet is easy and does not require an
IPL.
iSeries Navigator support creates and manages partitions including a
scheduled movement of resources where HMC is not available including:
– Configuration support of Linux with the Create Partition wizard
– The ability to save partition configuration data
– The ability to export configuration data to HTML format for hardcopy prints
– Partition numbers are visible with names
– The ability to change virtual processors when moving processing units
– Updates to partition profiles for shared and dedicated processors
– The ability to select views by selecting columns to display
Note: Some LPAR capabilities have hardware or software dependencies.
