Hitachi Compute Blade 500 Series Logical partitioning manager User's Guide
LPAR manager Overview
LPAR manager logically partitions the physical resources of one server blade
to create multiple server environments, each of which can operate
independently.
Each of the server environments constructed in this way from partitioned
physical resources is called an LPAR (Logical PARtition). It is possible to run a
different operating system on each LPAR simultaneously.
The operating system on an LPAR is called a guest OS. Each LPAR operates as
a completely independent and isolated server environment, and the guest OS
running on an LPAR is not affected by other LPARs.
The mode in which a server blade is logically partitioned to allow the
operation of multiple LPARs is called the LP mode. The conventional mode of
operating a server blade without partitioning is called the Basic mode.
Unless explicitly specified, the terms "physical" and "logical" are used in this
chapter as defined in the table below.
Table 1-1 Physical and Logical resources
Term Description
Physical Indicates the resources that actually exist in the system. "Physical" is
sometimes omitted, except where this would cause confusion.
Logical Indicates the logical resources that exist on an LPAR or for software on
LPARs. Thus, there may or may not exist an actual resource for each logical
resource.
An image when the system is booted in the LP mode is as follows:
Figure 1-1 System Activation in the LP mode
In addition, in this chapter:
• Symbols embraced by square brackets [ ] indicate keys on the keyboard.
• If two keys are joined by a "+", such as "A + B", it means the two keys
are to be pressed together

Logical Partitioning
Dedicated Resources and Shared Resources
Although the LP mode makes it possible to logically partition the hardware
resources of a server blade, the method of logical partitioning varies
depending on the hardware resource.
Some types of logical partitioning are shown in the table below.
Table 1-2 Type of Logical Partitioning
Term Description
Typical
Hardware
Resources
Dedicated The LPAR to which a hardware resource
has been allocated dedicatedly uses the
hardware resource and other LPARs
cannot use the hardware resource.
To switch the LPAR that can use
resources, make sure to shut down the
LPAR once to change the configuration
definition.
Processors
Memories
PCI devices
Shared Time-shared The particular LPARs to which a hardware
resource has been allocated timeshare
the hardware resource.
LPAR manager keeps switching LPARs
that can use the device at very short time
intervals.
Processors
PCI devices
Exclusive-
shared
One of the particular LPARs to which a
hardware resource has been allocated
exclusively uses the hardware resource.
The LPAR using the resource can be
switched dynamically.

Hitachi Compute Blade 500 Series Logical partitioning manager User's Guide
Logical Partitioning of Processors
The method of logically dividing the physical processor is referred to as the
scheduling mode. You can select dedicated mode or shared mode for the
scheduling mode. Different features of each mode are shown in the table
below.
Table 1-3 Processor Scheduling Mode
Mode Description
Recommended
System
Dedicated
Mode
• The logical processor on an LPAR dedicatedly
uses the corresponding physical processor.
• Since there is no overhead for switching the
physical processors between the logical
processors, the LPAR performs faster.
• For each LPAR, it is possible to specify the
number of dedicated logical processors
assigned. (However, it is not possible to specify
more than the number of physical processors
available.)
• System required
high processing
performance
• System required
critical time
period and high
processing in
performance
Shared
Mode
• Physical processors are time-shared among the
logical processors defined in the LPAR for which
the shared mode is specified.
• The utilization rate of the physical processors
can be set dynamically for each LPAR, allowing
flexible use of physical processor resources.
• The number of logical processors to be used in
the shared mode can be set for each LPAR. (It
is possible to specify more than the number of
physical processors available, but this
operations may cause the extremely slow
down.)

Scheduling mode dynamically change
Shared and dedicated LPARs can be switched dynamically without
deactivating.
a. The Scheduling mode of arbitrary Logical processor can be changed from
dedicated mode to shared mode.
b. The Scheduling mode of arbitrary Logical processor can be changed from
shared mode to dedicated mode.

Service Ratio
To the LPARs in the Shared Processor Mode, you can set the relative
processor resource allocation rate (called 'Service Ratio'), which represents
the ratio of the time period in which the LPAR actually run on the physical
processors (called 'Service Time'). The Service Ratio can be specified from 1
to 999.
LPAR manager partitions the performance of the physical processor used in
shared mode in 1 percent unit. LPAR manager calculates the relative
allocation rate of the service time with 10-millisecond time-slice accuracy,
which equals 1% of a unit processor time (1 second).
Service ratio has a meaning only to LPAR of shared mode. Service ratio does
not have any meaning to LPAR of shared mode, and cannot be assigned.
The examples of the relations between Service Ratio and allocation rate are
as follows.
(Example 1)
This example shows the allocation rates of LPAR1 (Service Ratio=100, the
number of the logical processors=2) and LPAR2 (Service Ratio=100, the
number of the logical processors=2) when the number of the physical
processor can be used by the shared mode LPARs is 3.
