2.3.19 Data that can be collected with virtualization systems that use Hitachi Compute Blade logical partitioning feature
- Organization of this subsection
(1) Hitachi Compute Blade logical partitioning feature functionality
Like other virtualized systems, Hitachi Compute Blade logical partitioning feature provides the following functionality:
-
Virtual networks
-
Virtual processors
-
Virtual memory
Hitachi Compute Blade logical partitioning feature manages the above functionality to implement a virtualized system. The logical partition must be stopped in order to change the virtual network or virtual memory, or to change the number of assigned virtual processors. The logical partition does not need to be stopped to change the virtual processor assignment percentages.
(2) Hitachi Compute Blade logical partitioning feature configuration
Like VMware, Hitachi Compute Blade logical partitioning feature has a parent/child configuration.
To set up a virtualized system on Hitachi Compute Blade logical partitioning feature:
-
Start the installed instance of Hitachi Compute Blade logical partitioning feature.
-
Create and set up a virtual machine.
-
Start the virtual machine.
(3) Using PFM - Agent for Platform on Hitachi Compute Blade logical partitioning feature
Keep the following in mind when using PFM - Agent for Platform on Hitachi Compute Blade logical partitioning feature.
- Installing PFM - Agent for Platform
-
Because Hitachi Compute Blade logical partitioning feature is configured in a special environment called an SVP frame, do not install PFM - Agent for Platform on an SVP frame.
- Processor information
-
Because a virtualized system based on Hitachi Compute Blade logical partitioning feature runs after the logical partition is set up, the number of processors is not changed while PFM - Agent for Platform is running. Accordingly, operation can be performed as usual, but the number of allocated processors may not match the number of processors that physically exist.
- Memory
-
Because a virtualized system based on Hitachi Compute Blade logical partitioning feature runs after the logical partition is set up, the amount of memory is not changed while PFM - Agent for Platform is running. Accordingly, operation can be performed as usual.
- Devices
-
Disk performance data is collected only for logical partition groups. System-wide performance data including the host OS cannot be collected. For the network adapter information, information about virtual network adapters allocated to the logical partition is obtained.
