When the HA function provided by server virtualization software is available for the VM hosts, and CPU capacity and memory capacity
are reserved for failover
In the case of VM hosts that meet the following conditions, the total capacity and the free capacity of the CPU and memory resources are
set to 0. Moreover, it is not added to the total capacity and the free space of the VM pool.
-
The VM host is configured on a physical L-Server.
-
The VM host is registered in a VM pool.
-
The physical server on which the VM host operates is released due to the usage change of a physical server.
If the VM host does not meet the following conditions, free space will be displayed as 0.
-
The power status is "ON".
-
The status is "normal".
-
Maintenance mode has not been set.
-
The maintenance mode of server virtualization software has not been set.
[VMware]
-
For VM hosts for which standby mode has been set by server virtualization software, calculation results are displayed for free space
even when the status is "stop".
In Resource Details for the VM host, and when using the command (rcxadm pool list -name
Resource_pool_name
), the total CPU capacity
is displayed in the format of
CPU_performance
*
CPU_core_count
.
CPU performance
is displayed as a number truncated to one decimal
place. Therefore, depending on the value of the second decimal place of CPU performance, CPU capacity may not match the actual free
CPU capacity.
Max. Number of Possible L-Servers View
This section explains how to display the converted number of L-Servers that can be created with VM pools, server pools, and storage
pools.
1.
Left-click the target VM pool in the orchestration tree, and select the [Resource List] tab.
2.
In the [Template] selection list, select the L-Server template to convert.
3.
Click <OK>.
The number of L-Servers that can be created is displayed in [Number of creatable L-Servers].
Note
-
When the status of the VM host and virtual storage is one other than "normal", the resource will be excluded from L-Server allocation
regardless of its available space. (*1)
However, a value corresponding to the available space of the resource will be displayed for the L-Server converted number.
-
When using physical L-Servers, the L-Server converted number of virtual storage is an estimate, and an error may occur during L-
Server creation.
-
The available space on resources and the space displayed for [Number of creatable L-Servers] are calculated as follows: (*2)
-
CPU, memory
Total_resource_capacity (*3) - (Total_of_resources_used_for_virtual_machines (*4)) -
Reservation_capacity_for_the_VM_host (the capacity reserved for the HA function enabled on the VM software)
(*5)
-
Addresses and available space on the network
Total_resource_capacity - (Total_of_resources_used_for_L-Server (*6))
