Use this information to understand upgrade terms.
Review this information to become familiar with the terminology used to
describe upgrades. If you are moving your data or software from your current iSeries™ server
to a server with a different serial number, see Migration terminology.
- Capacity on Demand
- The capability to activate additional processors on select iSeries servers.
These iSeries servers
are shipped with a number of processors that are active in your iSeries server
when it is shipped. These models also include processors that are not available
for use until you activate them. These processors can be either temporarily
or permanently activated.
- hardware upgrade
- An upgrade that refers to any of the following:
- A hardware change to a later level of the server hardware that maintains
the server serial number
- The addition of hardware to the server
- An enhanced hardware function
- licensed program (LP) upgrade
- A specific type of software upgrade for an existing server that refers
to either of the following:
- A change to a more recent release of the LP
- An enhancement in the LP function
- MES (miscellaneous equipment specification)
- Any server hardware change (addition, improvement, removal, or any combination
of these). The server's serial number does not change. Specific types include
the following:
- Customer-installable feature (CIF) MES
- Install-by-IBM (IBI) MES
- model upgrade
- A specific type of hardware MES that causes a change to the hardware model.
A model upgrade can involve adding, removing, or changing features. The server's
serial number does not change.
- operating system upgrade
- A specific type of software upgrade for an existing server that refers
to either of the following:
- A change to a more recent release of the operating system
- An enhancement in operating system function
- Processors on Demand (POD)
- Standby processors on a server that can be activated for permanent or
temporary use
- software upgrade
- Any software change to an existing server, which can include any of the
following:
- A software change to a more recent release
- A software addition
- An enhancement in software function
- system product division (SPD)
- A bus architecture that allows I/O to communicate to the processor. SPD-I/O
refers to devices that use the SPD bus architecture to communicate with the
rest of the server.
- source server
- The existing system that is being upgraded with new hardware or a new
level of software.
- target server
- In upgrades, the planned hardware configuration and software level that
exists when the upgrade is completed.
- upgrade
- Any hardware or software change to a later release, or any hardware addition
or software addition. Contrast upgrade with migration, where data is moved
from one iSeries server
to another iSeries server.
