Installed Software

Notes:

To see a listing of the IBM LPP’s (Licensed Program Products) installed on a system you can use both a 5250 green screen interface as well as System I Navigator.

To display this information using a 5250 emulation session issue the command ‘Go LICPGM’ then select option 10 – Display installed software. The command that is being called by this menu option is DSPSFWRSC (Display Software Resources).

To display this information using System i Navigator to view of all software installed on a system. You can display this by:

1.Expanding system folder under My Connections

2.Expanding Configuration and Service

3.Expanding Software

4.Clicking Installed Products

Power Hypervisor

System i servers work with a different structure when compared to the previous technologies used with AS/400 and iSeries servers. 

Above the POWER5 technology-based hardware is a code layer called the POWER Hypervisor. 

This code is part of the firmware shipped with the System i hardware. 

The POWER Hypervisor resides in flash memory on the Service Processor. 

This firmware performs the initialization and configuration of the System i hardware, as well as the virtualization 

support required to run up to 254 partitions concurrently on the System i servers. 

Partition Licensed Internal Code (PLIC) allows for management of multiple partitions of the System i hardware. 

It is included as part of the POWER Hypervisor.

The layers above the POWER Hypervisor are different for each supported operating system. 

The layers of code supporting Linux and AIX 5L consist of System Firmware and Run-Time Abstraction 

Services (RTAS).

Single Level Storage

All system storage (whether main storage or disk storage) is addressed in the same way. 

This single, device-independent addressing mechanism means that objects are referred to by name or name and library, never by disk location. 

All objects are created as if they reside in a 18,446,744,000,000,000,000 byte address space. That's 18.4 quintillion bytes!

The System i's virtual addressing is independent of an object's physical location, and the type, capacity, and number of disk units on the system.

What this means is that application programs do not require modification in order to take advantage of new storage technologies. 

Users can leave all storage management entirely to the machine.
