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

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.
Term Description
Table 1-2 Type of Logical Partitioning
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.
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.
Exclusive­shared
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.

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
Dedicated
Mode
Shared
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.)
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.)
Recommended
System
System required high processing performance
System required critical time period and high processing in performance
System required cost efficiency and flexibility rather than high processing performance
System required balanced processing between LPARs

Dedicated Mode
Example of Dedicated Mode is below

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.

This example shows the allocation rates of LPAR1 (Service Ratio=100, the number of the logical processors=2), LPAR2 (Service Ratio=100, the number of the logical processors=2) and LPAR3 (Service Ratio=100, the number of the logical processors=3), when the number of the physical processor can be used by the shared mode LPARs is 3, and LPAR3 is added while LPAR1 and LPAR2 are running.
LPAR manager modifies the allocation rate from the shared LPAR definition when it meets the following condition:
If the allocation rate for the calculation per logical processor is less than 1
If the number of logical processors allocated to a single LPAR does not

Idle Detection

A shared mode LPAR, which enabling its idle detection and not using so much CPU compared to the allocated rate, can give its processor time to another shared mode LPAR requiring it. The busy shared mode LPAR that takes over the processor time can use more processor-time than the allocation rate. As a result, the system can use CPUs time more efficiently.

satisfy the assigned allocation rate, the allocation rate is compensated to the one that is based on the number of logical processors.

Processor Capping

With the processor capping function on, the shared mode LPAR does not take on the unused (idle) capacity of other LPARs even if the LPAR requires more performance than its allocation rate (busy status). Therefore, the LPAR's processor-time never uses more processor-time the allocation rate, even if it is busy. However, because the LPAR manager allocation rate control allows a tolerance of 1% for each unit of processor-time, a shared mode LPAR is allocated a maximum processor-time that is 1% greater than the total service time of the physical processors assigned to it, and may exceed the allocation rate.
Note that the processor capping function does not affect the execution of the dedicated mode LPARs. Also processor capping has a meaning only to LPAR of shared mode. Processor capping does not have any meaning to LPAR of dedicated mode, and it cannot assign.

Processor Group

You can restrict the use of physical processors for a group of LPARs by forming a group of physical processors with one processor at the least. Any number can be defined as a number of a physical processor group. A processor with no processor number defined belongs to the processor group "0". A processor group number can be specified by the core.
Overview
A function which defines a processor core as a group and restricts the range of a shared processor to being in a group. It is possible to restrict in a group with effect of load-fluctuating by above mentioned. It is possible to define group by every user section and charge to an allocated processor performance.

Logical Partitioning of Memory

The memory size to be allocated to each LPAR can be specified for each LPAR (in multiples of 256 MB). Each guest OS has an exclusive use of the memory assigned to its LPAR. LPAR manager automatically determines which physical memory offset area(s) to allocate to an LPAR when the LPAR is activated.

Guest NUMA

Overview
NUMA (Non-Uniform Memory Access) is an architecture where memory is shared in a multiprocessor computer system. To create an LPAR that meets all of the conditions listed below, we recommend that you use a NUMA configuration so you can easily improve memory access and memory bandwidth. The NUMA running on an LPAR is called a guest NUMA.
You are creating an LPAR on a server blade in an SMP configuration.
You are creating an LPAR with the processor scheduling mode set to
allocated memory size may not be available depending on the specification and environment of guest OS.
amount applications use, memory swap may happen to cause performance degradation. When assigning an amount of memory, make sure to take the memory amount.
dedicated mode.
LPAR manager supports the following two methods for configuring logical processors for the guest NUMA: physical processor binding (for 02-0X or later) and physical NUMA node binding (for 02-40 or later). Physical processor binding is the method for associating logical processors with physical processors. Physical NUMA node binding is the method for associating logical processors with physical NUMA nodes. The table below explains specific differences between these binding methods with regard to how to configure an LPAR.

binding
Sets the number of logical processors in the entire LPAR.
Before the LPAR is activated, the user specifies the number of the physical processor that the user will manually assign.
Physical NUMA node binding
Sets the number of logical processors for each node
When the LPAR is activated, LPAR manager selects, in the ascending order of numbers, physical processors that exist in the automatically specified node and can be assigned.
Setting up a guest NUMA
The following describes how to set up a guest NUMA:
If the physical processor binding is used, follow the procedure below.
1. Configure the NUMA for the EFI.

7. Specify the memory. Specify the memory for each node. For details, see
Logical Partition Configuration on page 7-9.
Notes on the guest NUMA
Remember the following if you want to use the guest NUMA:
If you change the MM Config Base setting for EFI, the memory size that can be allocated to each node changes. For this reason, activation of the LPAR for which a memory node is specified might fail due to insufficient memory on the target node. If you change the MM Config Base setting, you must review the memory node number and the memory size allocated to each LPAR. For details on how to review the memory node number and the memory size allocated to each LPAR, see
Configuration on page 7-9.
If the guest NUMA is enabled in an LPAR, the default method for configuring logical processors for the guest NUMA is physical processor binding. This default method applies under the following circumstances:
¢
A change is made to enable the guest NUMA, which has previously been disabled.
¢
LPAR configuration information is inherited in which the guest NUMA is enabled. This LPAR configuration information was previously saved in LPAR manager when LPAR manager did not support the physical NUMA node binding.

L3 cache allocation functionality

Overview of the L3 cache allocation functionality
You can use the L3 cache allocation functionality to divide the L3 cache among multiple LPARs and allocate part of the divided cache to each LPAR. This functionality uses Cache Allocation Technology (CAT), which is provided as part of Intel Resource Director Technology (RDT).
If, for example, you operate an LPAR that requires response performance (web server) and an LPAR that puts a high load on the memory (database) at the same time, data of the LPAR (web server) might be forced out from the L3 cache, and degradation or variance in response performance might occur. You can prevent such degradation or variance in response performance by using the L3 cache allocation functionality to secure the L3 cache space required for the LPAR (web server).
By default, the entire L3 cache is allocated to each LPAR, but you can dynamically change the size of the L3 cache space that is allocated to each LAPR. Note, however, that you can change the L3 cache allocation only for LPARs to which processors have been allocated in dedicated mode.
You can allocate L3 cache space to LPARs by using the capacity bit mask (CBM) format (a mask value format). By using a CBM, you can specify not only the size of the L3 cache space to be allocated to LPARs, but also detailed settings such as the distance and overlapping of L3 cache allocation among LPARs. Each specified CBM value must be in the range of the implemented bit width of the CBM and must be a combination of consecutive ones (1). For example, if the implemented bit width of the CBM is 20, FFFFFh, 0FF00h, and 0003Ch are acceptable, but values such as 10001h, 00100h, and 0F0F0h are not acceptable. As shown below, there are three possible combinations of CBMs for multiple LPARs. In the following figure, the implemented bit width of CBMs is 8.

Figure 1-19 L3 cache allocation to LPAR
In the case indicated by (1), all three LPARs can access the entire L3 cache. In the case indicated by (2), the L3 cache space allocated to the LPAR of lower priority can be shared with the LPAR of higher priority. In the case indicated by (3), the cache can be divided among isolated LPARs.
To allocate L3 cache space to LPARs, use the HVM management command (HvmSh). You can also use the HVM management command (HvmSh) to display the CAT-related configuration information required to use the L3 cache allocation functionality, and the usage status of the L3 cache allocation functionality. For details, see the HVM Management Command (HvmSh) Operation Guide.
Enabling the L3 cache allocation functionality
To enable the L3 cache allocation functionality:
1. From the Web console, enable Performance tuning options. For details, see
2. Specify the L3 cache allocation settings by using the HVM management command (HvmSh), execute the opr LparCatCbm command.
For details, see the HVM Management Command (HvmSh) Operation Guide.

NIC (Network Interface Card)

LPAR manager supports the following four virtual NIC functions. A shared NIC, VF NIC, and virtual NIC are collectively called "Logical NIC".
Item Description
Dedicated NIC Stable performance: not affected by other LPARs
High-speed data transmission
Shared NIC A physical NIC can be shared by multiple LPARs.
Performance depends on the number of LPARs and traffic volume.
Less restrictions on NIC functions than VF NIC.
VF NIC SR-IOV, a physical NIC function, is used. Supported physical
NIC, server blade, and OS are limited.
High-speed data transmission equivalent to Dedicated NIC
Lighter load on physical processors than Shared and Virtual NIC
Transmission bandwidth can be limited by the 100 Mbps.
Virtual NIC Available only for inter-LPAR transmission
No physical NIC is required.
Dedicated NIC
LPAR manager supports assigning of Dedicated NIC. Shared NIC is useful for solving lack of hardware resources and increasing use efficiency of devices on the virtual environment.
Dedicated NIC brings high performance for communication without influences from other LPARs.
Shared NIC
Network segments for shared NICs can be assigned when the NIC scheduling mode is set to shared mode.
NIC assigned the network segments is called "Shared NIC".
Network segments can be set on Virtual NIC Assignment Screen.
The maximum number of physical LAN controllers which can be assigned to LPAR manager is 8 and the maximum number of physical ports which can be assigned to LPAR manager is 16.
The following tables show a combination of logical port numbers, a detection number of LAN controller and network segments for each hardware configuration as examples.

Figure 1-23 Definition of Network Segment ID on LPAR manager
In the figure above, an external network is used to establish communication between shared NIC #0 of LPAR1 set to segment 1a and shared NIC #1 of LPAR2 set to segment 1b or shared NIC #2 of LPAR2 set to segment 2a.
Note:
Total throughput of shared NICs is 3 Gbps per LPAR manager.
Tip:
For communication between shared NICs set to a same network segment, an external network is not used.
However, for communication between shared NICs to different network segments, an external network is used.
VF NIC
A network segment of VF NIC can be set when SR-IOV as a hardware function of physical NIC is available on LPAR manager, and NIC scheduling mode is shared mode.
NIC assigned the network segments is called "VF NIC".

Communications between NIC#0 on LPAR1 (assigned to segment 1av), NIC#1 on LPAR2 (assigned to segment 1bv) and NIC#2 on LPAR2 (assigned to segment 2av) have to go through external network.
Tip:
Communication between VF NICs connected to the same network segment does not use an external network. In contrast, communication between VF NICs connected to different network segments takes place over an external network.
Virtual NIC
Up to 4 Network Segment for Virtual NIC can be defined on an LPAR manager. NIC assigned the network segments is called "Virtual NIC". Virtual NIC can communicate through no physical NIC network between LPARs.
LPAR manager Functions
Hitachi Compute Blade 500 Series Logical partitioning manager User's Guide
1-31
Assignments of Virtual NIC to Network Segment are assigned on the Virtual NIC Assignment Screen. Usable Network Segment IDs are Va, Vb, Vc, Vd.
On the above chart, NIC #0 on LPAR1 (which is assigned to Segment Vc) can communicate to NIC #1 on LPAR2, but NIC #0 on LPAR1 cannot communicate to NIC #2 on LPAR2 (because their segments are different). Virtual NICs on the same Segment can communicate each other.
Note:
Total throughput of virtual NICs is 3 Gbps per LPAR manager.
Tip:
Each Virtual NIC on the same Network Segment can communicate each other.
However Virtual NICs on the different Network Segment cannot communicate each other.

Management Path

The network path configured for server operation is called "operation path". The network path configured for management and operation of server and LPAR manager is called "management path".
Figure 1-25 Assignment of Virtual NIC
1-32
Before starting LPAR manager, you must configure a management path to be used for communication between LPAR manager and the management module. The scheduling mode must be set to shared mode for the NIC to be set for the management path.
Also, the IP address of the LPAR manager to be used for the management paths is called the LP IP address.
The dedicated NIC for the management path is not mounted in CB 500. Thus, NIC used for LPAR (guest OS) is used in the shared mode. (LPAR manager
LPAR manager Functions
Hitachi Compute Blade 500 Series Logical partitioning manager User's Guide
automatically sets the NIC used for the management path in the shared mode. You cannot set the NIC in the dedicated mode.)
The LPAR manager firmware for which the version is earlier than 02-2X uses the port 0 and port 1 (which are 1a and 1b in the virtual network segment) of the Onboard NIC 1 (or the LAN Mezzanine card 1 if no Onboard NIC is installed) as the management path. You cannot specify a NIC to be used as the management path.
For an LPAR manager firmware version 02-2X or later, you can specify any two ports on the NICs installed on the server blades, as the management path. If you specify ports on different NICs as the management path, the management path communication can be maintained in case of a NIC failure.
If the state of the ports or network failure does not occur, either of the two ports become active state. The other port as the standby system. This port used to communication with the network when the port of active state has failed. Note that the primary management path does not become active instead of the secondary management path even if the primary management path recovers when the secondary management path works. A redundant configuration is maintained after recovery of the primary management path.
You can also specify only one port as the management path. In this case, the management path is non-redundant.
If you do not specify the management path, the port 0 and port 1 (which are 1a and 1b in the virtual network segment) of the Onboard NIC 1 (or the LAN Mezzanine card 1 if no Onboard NIC is installed) are used as the management path.
Tip:
We strongly recommend that you explicitly specify a NIC to be used for management path communication.
If you do not explicitly specify a NIC to be used for management path communication, the scheduling mode of the NIC to be selected as a management path needs to be able to be set to the shared mode. If the NIC cannot be set to the shared mode, LPAR manager cannot start.
Specifying the management path

The scheduling mode of the NIC that is used as the management path
The initial value of the scheduling mode of the NIC that is used as the management path is the shared mode; therefore, you can use the NIC as the management path without having to change the scheduling mode.
If you want to change the management path of the operating LPAR manager, before changing the management path, change the scheduling mode of the NIC you want to use as the new management path to the shared mode.
If a port you specified as the management path is on a NIC that is set in the dedicated mode, LPAR manager operates as follows:
The scheduling mode of the specified NIC changes to the shared mode. As a result, if the number of controllers of the NICs in the shared mode
LPAR manager Functions
Hitachi Compute Blade 500 Series Logical partitioning manager User's Guide
exceeds 8, or if the number of the ports exceeds 16, the scheduling mode of the NIC that has the largest PCI bus number among the existing shared-mode NICs changes to the dedicated mode (so that the number of controllers and the number of ports on the shared-mode NICs are within the upper limits).
If the NIC for which the scheduling mode changed as above has been allocated to an existing LPAR, the NIC allocation to that LPAR is released.
If these changes occur, one of the messages below is recorded in the LP system log messages. A log message is also recorded in the system event log (SEL) of the system unit, and an alert is sent to HCSM.

¢
Saving the configuration
If LPAR manager changes to the safe mode, confirm the ports specified as the management path and the configuration of the LPAR for which allocation is released, and modify the configuration if needed.
After confirming the LPAR configuration, release the safe mode and then, if needed, save the configuration. Alternatively, if the ports specified as the management path are incorrect, shut down LPAR manager and then specify the correct ports.
LPAR manager Functions

In this case, the "Auto Activate" setting of the LPAR is also suppressed. The LPAR for which "Auto Activate" is set is not automatically activated after the safe mode is released. Activate the LPAR manually, or restart LPAR manager and then execute the "Auto Activate" function.
Downgrading the firmware
To restore the version of LPAR manager, management module, and server blade firmware to a previous version, reset "Specify management NIC" of the management path setting to "Disable" in advance, and then connect the management path to 1a / 1b.
N+M cold standby
The versions of LPAR manager firmware, management module firmware, and the server blade firmware on the standby server blade must be equal to or later than those on the active server blade. If one or more firmware versions are earlier than those indicated in the "Firmware combinations" table, the standby server uses not the specified ports but the default ports (1a/1b) as the management path after failover, so LPAR manager fails to start or starts in an unexpected state.
For details on the firmware combinations, see
Firmware combinations on
page 1-34.
Cloning
The cloning function of SC/BSM does not inherit the setting of ports used as the management path. At the cloning target, manually set the ports before booting LPAR manager.

If the performance of the management path is reduced, check the processor usage for network communication in SYS2 of the LPAR Usage screen.
If the value of Dsp (ms) of SYS2 is 1800 ms or higher, the problem is most likely caused by the overloading of the shared NIC. To reduce the load, review the network configuration of the shared NIC or remove the cause of the heavy load on the shared NIC.

Using SR-IOV functions
The following procedure shows how to use SR-IOV functions.
Update LPAR manager firmware
If your LPAR manager firmware does not support SR-IOV, update it to one that supports SR-IOV. For details about updating LPAR manager firmware, see the Hitachi Compute Blade 500 Series Management Module Setup Guide.
Update NIC firmware
If your NIC firmware does not support SR-IOV, update it to one that supports SR-IOV. For details about updating NIC firmware, see the Server Blade 10Gb CNA/LAN Product Firmware Update Guide. Note that in LP mode you cannot update NIC firmware. Change to Basic mode before updating NIC firmware.
Set up SR-IOV
For details about setting up SR-IOV, see the Hitachi Compute Blade Emulex Adapter User's Guide for Hardware. Note that in LP mode you cannot set up SR-IOV. Change to Basic mode before setting up SR-IOV.

Update the NIC driver
If your NIC driver does not support SR-IOV, update it to one that supports SR-IOV. For details about updating the NIC driver, see the Hitachi Compute Blade Emulex Adapter User's Guide for Driver.
Notes
Note the following when using the SR-IOV functionality:
In a Windows environment, you cannot use LPARs to which both a dedicated NIC and a VF-NIC are allocated.
Note the following when configuring a teaming interface with VF NIC ports.
¢
When you configure a teaming interface, you need to specify the MAC address originally set for one of the VF NIC ports to be set in the same team, for all of the VF NIC ports.
Also, when you remove a teaming interface, reset the original MAC address for each VF NIC port.
¢
If HCSM detects duplication of a MAC address, HCSM does not allow you to migrate the LPARs on an LPAR manager.
¢
HVM Navigator does not allow you to set a MAC address for multiple VF NIC ports.
For the method for configuring a teaming interface and that for removing a teaming interface, see the following.
Configuring a teaming interface
a. Boot a guest OS to which VF NIC ports assigned, with the original
MAC address set for each of the VF NIC ports to be set in a team. Note that, when you remove a teaming interface, you need to reset
the original MAC address for each of the VF NIC ports. We recommend that you take a note of the original MAC addresses.
b. Confirm that each VF NIC port can communicate by issuing the ping
command. c. Shut down the guest OS. d. Push F6 on the Virtual NIC Assignment screen. Then, specify the
MAC address originally set for one of the VF NIC ports, for all of the
VF NIC ports.
For example, to configure a team with VNIC#0 and VNIC#1, specify
the MAC address of VNIC#0 for VNIC#1. e. Boot the guest OS. f. Confirm that the same MAC address is set for all of the VF NIC ports
to be set in a team.
For confirming a MAC address, select [Start]-[Control Panel]-[Network
and Internet]-[Network and Sharing Center]-[Change adapter
settings], and then double-click a network device. In the opened
dialog, push [Details], and then see the value of "Physical Address".

Port Multiple Assignment

Logical NIC supports the Port Multiple Assignment function. Port Multiple Assignment can be set on the Virtual NIC Assignment screen.
This function makes it possible to assign multiple ports of physical NIC the target LPAR.
The function is efficient especially when small number of NIC cards are installed, because the number of segments more than the number of physical NICs can be assigned.
Figure 1-26 Port Multiple Assignment of Logical NIC

Port Separate Assignment

Logical NIC is also supporting the Port Separate Assignment function. Port Separate Assignment can be set on the Virtual NIC Assignment screen.
This function makes it possible to assign each port (for example; "1a" and "1b") on the physical NIC separately to the target LPARs. So, the availability

TagVLAN

Summary
Logical NIC support the TagVLAN function which is based on the IEEE 802.1Q. Flexible network environment can be built by using the TagVLAN function.
Multiple broadcast domain can be built by using only a physical NIC.
Multiple VLAN ID can be assigned to Logical NIC.
Network interface between physical NIC and network switch uses the tag whose form is the IEEE 802.1Q.

Figure 1-28 Outline of Tagged VLAN Function
TagVLAN Function
TagVLAN function has two modes. And the function is enabled by setting mode to either one. (This function can be set on the "Virtual NIC Assignment" screen)
Untagged Port This setting is for receiving untagged frames from one specified VLAN
group. A Logical NIC for which "untagged port" is specified receives only frames
from the group with the same VLAN ID number, and these frames do not include tags. When transferring frames from a Logical NIC specified as an "untagged port" to an external switch or to a Logical NIC specified as a "tagged port" in the same VLAN group, the frames are tagged with the IEEE802.1Q format.
If "untagged" is specified, only one VLAN ID can be specified.
Tagged Port With this setting, a NIC receives frames containing IEEE 802.1Q-format
tags and untagged frames that include any of the specified VLAN IDs. A Logical NIC for which "tagged port" is specified can receive both tagged
frames with the specified VLAN ID and untagged frames. Tagged frames sent from a Logical NIC with the "tagged port" specification are sent to the same group as the VLAN ID in the tag, and untagged frames are sent to groups for which no VLAN has been set.
When frames are transferred to external switches, they are transferred as they are, with or without tags. When specifying "tagged" for a Logical NIC, you can set up to 16 VLAN IDs for one Logical NIC. To use more than 17, set "ALL" to allow all VLAN IDs to be received.

By combining the above Logical NIC settings and guest OS VLAN settings, you can divide broadcast domains as follows.
Divide a virtual network into multiple broadcast domains for each Logical NIC
On the Virtual NIC (VNIC) Assignment screen, specify "untagged port" for the Logical NIC and the VLAN ID to which it belongs. There is no need to make VLAN settings in the guest OS because there will be no tags on the packets received by the Logical NIC. This means that the guest OS will not be aware of the VLAN, so you can divide the broadcast domain for each Logical NIC.
Assign one Logical NIC to multiple broadcast domains within the same virtual network
By making VLAN settings for the Logical NIC from the guest OS, you can use the functions equivalent to the physical NIC to operate tags and perform frame filtering. In addition, on the Virtual NIC (VNIC) Assignment screen, specify "tagged port" for the Logical NIC and specify all the VLAN IDs specified for the Logical NIC in the guest OS.
This will make it possible to handle more than one VLAN ID per Logical NIC and assign the Logical NIC to more than one broadcast domain.

Attention
Logical NICs do not support advanced communication control functions (for example, IGMP snooping, access lists, and QoS). Use communication control functions of external switch modules. To control communications between LPARs on the same LPAR manager, use the VLAN function of a logical NIC or the Inter-LPAR communication packet filtering.
Communication with external networks using VLANs Because IEEE802.1Q tagged packets pass through the external physical switches, it is necessary to set the VLAN ID used by the virtual network corresponding to the shared physical NIC to physical switch port at the tagged port.

Packet Filtering of Inter-LPAR

To ensure the independence of LPAR networks within the same server blade and to shield networks from external networks, communication packets between LPARs can be filtered. This subsection describes filtering setting values, descriptions of functionality, communication-destination environments, and behaviors.
Disable setting for inter-LPAR communication packet filtering
¢
This is the default value and the basic operation of the shared NIC.
¢
When the communication source and the communication destination are in the same network segment, LPAR manager transfers packets to the destination LPAR via the virtual switch.
¢
When the communication source and the communication destination are in different network segments, packets are transferred to the external network.
Enable setting for inter-LPAR communication packet filtering
¢
Even when the communication source and the communication destination are in the same network segment, LPAR manager disconnects inter-LPAR communication via the virtual switch.
¢
LPAR manager transfers all packets to the external network.
¢
Use this setting when systems that do not communicate each other are integrated into the same server blade.
Disable (ALL) setting for inter-LPAR communication packet filtering
¢
When the communication source and the communication destination are in the same network segment, LPAR manager transfers packets to the destination LPAR via the virtual switch, and then transfer the packets to the external network.
¢
When the communication source and the communication destination are in different network segments, LPAR manager transfers packets to the external network.
¢
Use inter-LPAR communication within the range of the maximum possible bandwidth of the LAN switch because all packets are transferred to the external network.

HBA-core dedicated mode

Overview
HBA-core dedicated mode is an optional function for FC ports that are set for shared fibre channels (FCs). For an ordinary shared FC, multiple LPARs use multiple processing cores (HBA cores) existing in an FC adapter in a round­robin manner to send and receive data (see FC Port 1 (HBA-core dedicated mode is disabled) in the figure below). Therefore, for I/O processing between LPARs that share the same FC port, performance is determined on a best­effort basis, and performance cannot be guaranteed.
However, for a shared FC with HBA-core dedicated mode enabled, only specific HBA cores are responsible for sending and receiving data of specific LPARs, and are not affected by other LPARs (see FC Port 0 (HBA-core dedicated mode is enabled) in the figure below). This prevents performance degradation due to I/O load by other LPARs that share the same FC port, thus ensuring stable performance.
Figure 1-37 Definition of FC Port

Requirement
Install a version of Fibre Channel driver and a version of Fibre Channel firmware supporting the HBA-core dedicated feature. For the versions of Fibre Channel driver and the versions of Fibre Channel firmware supporting the HBA-core dedicated feature, see the HITACHI Gigabit Fibre Channel Adapter USER'S GUIDE (Support Matrix Edition).

Notes:
1. In the same way as for an ordinary shared FC, vfcIDs can be assigned to LPARs. However, if HBA-core dedicated mode is enabled, the maximum value of the vfcID that can be assigned is limited to the number of HBA cores on the FC adapter. Although a vfcID greater than the number of HBA cores can be assigned to the LPAR, activation of the LPAR is suppressed.

Setting procedure
You can use HvmSh to set HBA-core dedicated mode to FC ports that are configured as Shared FC.
Notes
Even if HBA-core dedicated mode is enabled, because it is inevitable that resources shared by other LPARs (for example, FC ports) exist in the system, the other LPARs might interfere with performance. To reduce the system's vulnerability to this interference, take the following points into account when you build the system:
Make sure that the RAID group of the LU being used is not shared by other LPARs or systems.
Set the maximum bandwidth for the FC port. As a result, LPARs that share the FC ports become less likely to be affected by the concentration of communication.
For a system running in LPARs that share the same FC port, it is recommended that the system requests less large-volumed I/O processing and more small-volumed I/O processing for the storage.
Restrictions
The following shows major restrictions that are placed if HBA-core dedicated mode is enabled:
Setting the HBA-core dedicated mode You must deactivate the LPARs to which an FC port is assigned in advance
when you change HBA-core dedicated mode to the FC port from a value of "enabled" to that of "disabled", and vice versa.
Maximum number of FCs that can be shared The maximum value of the vfcID that can be assigned is limited to the
number of HBA cores in the FC adapter. Although a vfcID greater than the number of HBA cores can be assigned to the LPAR, activation of the LPAR is suppressed.
Maximum performance An LPAR cannot use HBA cores that are not allocated to the LPAR (even
when they are idle). Therefore, the maximum IOPS that can be obtained with one core determines the overall maximum IOPS.
For example, if HBA-core dedicated mode is enabled for an FC adapter that has 2 cores per port, the maximum IOPS is half the maximum IOPS obtained when HBA-core dedicated mode is disabled.

Only one core can be assigned to an LPAR.
LPAR migration The same vfcIDs that are used at the migration source must be
unassigned at the migration destination. If the same vfcIDs are already assigned at the migration destination, LPAR migration fails.
Note:
In CB 520X B1/B2/B3, a KVM device or a remote console are assigned to a LPAR by Exclusive Shared Mode, however, a USB device is assigned to a LPAR by Dedicated Mode.

Overview of Virtual COM Console
The conventional system console can select and operate one of the LPAR manager screen and guest screens, but the virtual COM console can use a higher-speed console than normal serial console for each LPAR with the serial over LAN function of the LPAR manager. Concurrent operation of multiple LPARs is enabled operating guest screens by using the virtual COM console instead of the system console. Up to 16 LPARs can be simultaneously connected to the virtual COM console.

Currently allocated TCP ports can be monitored with the procedure in "(1) Enabling Virtual COM Console Function on the LPAR manager Screen. Use Tera Term when using one or more virtual COM consoles. Furthermore, for stable operation of Tera Term, it is recommended that the Scroll Buffer value be set to 2000 lines on the screen displayed by clicking Settings(S) > Window(W).
– On the New Connection screen at the boot of Tera Term, enter the LP IP Address and TCP port. Then click OK.
– OS prompt will appear when the connection is successful. Here you can operate the guest OS.
– If the connection fails, a popup message informing "Error" will be displayed. Connection failures are as follows:
¢
TCP/IP communication to the LP IP Address is unavailable. Check the path to the LP IP Address.
¢
If changing a TCP port, the TCP port may not be connected depending on the terminal OS setting or account privilege. Confirm that the TCP port is available for connection on the terminal before changing a TCP port. It is recommended to use a TCP port with the default value that is verified enough.

Switching the Virtual COM Console and System Console The LPAR guest screens can be operated from either virtual COM console
or conventional system console. These two types of console are exclusively available and operation by the conventional system console takes precedence. The virtual COM console can operate LPAR guest screens while the system console is displaying the LPAR manager screen. Consoles to operate LPAR guest screens can be selected by switching an LPAR guest screen and the LPAR manager screen on the system console.

In SSH connections, an SSH host key is used. An SSH host key is automatically generated when an instance of LPAR manager with a firmware version of 02-05 or later starts for the first time. In addition, you can re-create the key through operation. 2,048-bit fixed RSA keys can be created as SSH host keys. The length of SSH host keys that can be created is fixed at 2,048 bits and the key type is RSA.

Notes for Virtual COM Console
Notes on Telnet or SSH Connection
You can change a port number to specify when connecting to a guest screen through Telnet or SSH, which needs to be different from a port number for LPAR manager. See
D-2 for details. Some port numbers may not be available depending on
the OS settings, account privilege, installation software, or network environment. Check which port is available on the terminal and in the network environment before changing the port number. When there is no problem for use, it is recommended that you use a default port number among serial numbers starting from 20801, which have been thoroughly verified.
Only one terminal per LPAR is permitted to operate guest screens from the virtual COM console. If a connection to two or more terminals is attempted, the connection to the second or more terminals is disabled.
If the guest screen cannot be displayed while connecting to the virtual COM console, check the serial console configuration.
If a LP IP address for IPv4 is not specified, you cannot disable Telnet authentication. Select Enable for Telnet authentication or select SSH for connection mode.
If Telnet user authentication is disabled, Telnet connections cannot be established to LP IP addresses for IPv6.
If a communication failure occurs during a connection to a virtual COM console, reconnection to that virtual COM console might become impossible.
In such a case, specify "N" for the port setting of the affected virtual COM console, and then return the setting to its previous value.
After doing so, reconnection will become possible after a certain amount of time elapses (after a maximum of 17 minutes).

Notes on Guest Screen Operation
Although the virtual COM console can operate multiple LPARs concurrently, the performance of consoles of other LPARs may decrease with an increase in output data.
If a large amount of characters are pasted to a guest screen, a part of characters may not be pasted. 256 or more characters per line for the Windows command prompt, and 1024 or more characters per line for Linux prompt cannot be pasted. In addition, if 1024 or more characters are pasted for the Linux prompt, Linux may hang up or unexpected screen operation may occur. The number of characters that can be pasted stably without being lost is less than 256 per line for the Windows command prompt, less than 1024 per line for the Linux prompt, and less than 10000 per line for editing programs including the Vi editor. When

pasting characters, it is recommended that a large amount of characters be divided into several blocks (up to the upper limit of characters per block), and then be pasted.
When you connect the system to the virtual COM console and boot the guest OS, Windows may halt its boot with the EFI screen; Linux may halt its boot in the grub console; even though rarely. If it happens, press the Enter key to resume the boot.
Notes on Operation
Connect to the virtual COM console when needed in usual operation. Virtual COM console response might stop when it stays connected to LPAR manager. Reconnect the virtual COM console then. We recommend that VC (virtual COM console) on the Logical Partition Configuration screen should be assigned to an LPAR when needed and the assignment should be released when not needed.
If you repeatedly change settings for VC (virtual COM console) on the Logical Partition Configuration screen with the virtual COM console connected, the console screen may be disturbed. If so, perform Edit (E) > Screen clear (S) in Tera Term to clear the screen, which can correct the screen disturbance.

Logical VGA Snapshot

LP Web systems may display different contents depending on different LPAR manager firmware versions.
Overview of Logical VGA Snapshot
LPAR manager supports the logical VGA snapshot with which users can view and acquire images that the guest OS running on each LPAR outputs to the display unit. With this function, images each LPAR outputs to the display unit can be acquired at any time as snapshot images (still images). To do this, access is made to the web server for acquiring snapshot images provided by the LPAR manager, using the Web browser from an external console. The following figure shows the logical VGA function configuration.
For details, see the Hitachi Compute Blade 500 Series Logical VGA snapshot.
Note that you can use the HVM management command (HvmSh) to disable HTTP communications. To disable HTTP communications, you need to restart LPAR manager. For details about the command, see the HVM Management Command (HvmSh) Operation Guide.
LPAR manager uses a built-in certificate signed with SHA-1 in http communications.
2-10
We do not recommend that you use the certificate owing to insecurity. We recommend that you use the server certificate for LPAR manager, instead.

Time Adjustment

Logical Partitioning of Timers
LPAR manager manages five kinds of time shown in the following table. LPAR manager creates each time using differentials between different times. Based on the LPAR manager system time, LPAR manager creates the logical timer for each LPAR. A guest OS on the LPAR manages "OS system time" using this logical timer.
LPAR manager manages the following time shown in the table below.

If you shut down or reboot LPAR manager before saving it or the N+M cold standby function changes server blades, the adjusted differentials are lost.
3. When you use the kernel parameter which LPAR manager does not recommend, the following phenomenon may occur; such that boot fails or "OS system time" differs from actual time greatly.
4. You can select LP TimerCounter Base on LP Options screen. LP TimerCounter Base is displayed when the timer precision of "TSC" is lower during operation, you can select "TSC" or "Cpu Frequency". Select the smaller one for time-lag. LP TimerCounter Base is not displayed when the timer precision of "TSC" is higher, "TSC" is operated. For details of setting, see

Power Saving

System Idle Loop

LPAR manager waits dispatch target process when the target processes does not exist on the LPARs (Host idle loop mode). This mode lowers power state of physical processor for reducing power consumption.

Power Capping Function

Power Capping Function set maximum power consumption (Power Capping Level) per chassis. This function aims to decrease power consumption of

blades by lowering power state of processors. And this function automatically set processors state to power saving mode when workload of the processors are low level. Power Capping Function is enabled by Management Module. (This procedure is same as Basic Mode) See Power Capping on page 10-22 for notes.

Transfer

Transfer to LPAR manager environment from Basic environment

Note:
In Windows, if you transfer between Basic environment and LPAR manager environment while setting a static IP address in NIC, IP address is set in the old MAC address. And duplication errors occur due to IP address resetting. Therefore, you need to delete IP address before transfer to avoid the duplication error.
Types of NIC and MAC addresses are different between LPAR manager environment and Basic environment. Therefore, you need to install the driver when migrating for first time.
WWPN/WWNN of HBA are different between LPAR manager environment and Basic environment. Therefore, you need to change the setting of SANS security in the storage.
