The pool list in the resource list display the resource folders, total size of resources, and free space available.
In the L-Server list, when the server is a physical L-Server, the physical server for the L-Server is displayed.
When the server is a virtual L-Server, the name of the VM host where the L-Server operates is displayed.
When the [Current resource] checkbox and the [Preserved resource] checkbox are selected, resources that have been allocated and resources in use are displayed.
For the already allocated resources, the following information is displayed, depending on the status of resource allocation.
allocated
Resource name
preserved
Resource name + "(preserved)"
defined
"(defined)"
For resources in use, the resources configured as [Physical server] or [VM host] are displayed as icon + resource name.
If you select the [Resource List] tab with a resource pool selected in the orchestration tree, a list of information for the resources that belong to the resource pool are displayed.
If you select the [Resource Details] tab, detailed information such as the total size of data and free space in the resource pool is displayed.
Also, if you select the [Available Pool] tab, a list of the resource pools that the user has usage rights for and the resources that belong to those pools is displayed.
For virtual storage resources with Thin Provisioning attributes configured, the virtually allocated size will be displayed inside the used amount. Also, depending on the value of the virtually allocated size, the display of free capacity may differ as follows:
When the virtually allocated size is less than the total size of virtual storage resources
The area not virtually allocated is displayed in the free capacity.
When the virtually allocated size is more than the total size of virtual storage resources
The area exceeding the capacity is displayed preceded by a minus ("-") in the free capacity.
For VMware datastores, when storage pools with Thin Provisioning attributes are registered, they are displayed as explained above.
Example
When the total size of virtual storage resources is 20 GB, and the virtually allocated size is 10 GB:
Total Capacity: 20.0GB
Free Capacity: 10.0GB
When the total size of virtual storage resources is 20 GB, and the virtually allocated size is 30GB:
Total Capacity: 20.0GB
Free Capacity: -10.0GB
The combined total of the capacity of the virtual storage and disk resources registered in the resource pool is displayed for the total capacity of the storage pool. If a disk resource that has been separated from a virtual storage and that virtual storage exist in the same resource pool, the capacity of the disk resource will not be included in the calculation of the total storage capacity of the storage pool.
Note
When the following conditions are met, the capacity reserved for failover is displayed in [CPU Capacity] and [Memory Capacity] under [VM Host List] and [Capacity] on the [Resource Details] tab. For VM hosts for which the HA function is unavailable, or for operations with no reservation for failover, a hyphen ("-") is displayed.
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
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.
Left-click the target VM pool in the orchestration tree, and select the [Resource List] tab.
In the [Template] selection list, select the L-Server template to convert.
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)) |
Free storage space
Total_resource_capacity - (Total_of_resources_used_for_L-Server (*6) + Total_of_images (*7)) |
Free disk space
Free space as a resource is not displayed.
The free space is calculated as the free space of a resource pool when the following conditions are met:
Disks are not used for L-Servers or cloning images
Number of creatable L-Servers is displayed as follows:
When the number of disks specified for an L-Server template is 1, and when the disk capacity specified for an L-Server template is the same capacity as or smaller than the disk resource
1 is displayed.
When the number of disks specified for an L-Server template is 2 or larger, or something other than the above
0 is displayed.
[Hyper-V]
As the saved disk resources that are created from the virtual machine cannot be used as system disks, the number is 0, even if the L-Server is unused.
Number of L-Servers that can be created
The following smallest value is displayed:
Free CPU capacity / the CPU capacity specified in the L-Server template selected from the "Template" select list
Free memory size / the memory size specified in the L-Server template selected from the "Template" select list (*8)
Free storage capacity / the storage capacity specified in the L-Server template selected from the "Template" select list
*1:
[VMware]
The VM hosts for which standby mode has been set by server virtualization software are excluded from the targets of L-Server deployment, and other VM hosts in the same cluster become the deployment target location.
[Hyper-V]
When using an L-Server template with dynamic memory settings enabled, VM hosts that do not support dynamic memory are excluded from being the targets of L-Server deployment. In this case, "0" is displayed for the L-Server conversion number, even when there is available space on resources.
*2: For the resource pool (VM pool) configured as a resource pool for overcommit, the capacity is calculated according to the specified calculation method for free space.
When configured to calculate using a maximum value, free CPU capacity/memory size are calculated based on the CPU performance/memory size of the virtual machine.
Point
When creating a virtual L-Server, if the CPU reservation performance and memory reservation capacity are not specified, the values are configured as follows:
CPU reservation performance: 0
Memory reservation capacity: memory capacity or initial memory size
[VMware]
When configured to calculate using a reservation value, free CPU capacity/memory size are calculated based on the CPU performance/memory size reserved for the virtual machine. The number of L-Servers that can be created is calculated based on the CPU reservation performance and the memory reservation capacity specified in the L-Server template.
When the free capacity for VM pools is configured to be calculated using a maximum value, for the virtual machine for which limit values of CPU/memory has been set to "Unlimited" using VM management software, the calculation is performed assuming the following values as the maximum values:
When no limit has been set for CPU performance
The physical CPU performance on the VM host is used
When no limit has been set for memory size
The memory size set for the virtual machine
[Hyper-V]
When configured to calculate using a reservation value, the values referred to for calculation vary depending on the dynamic memory settings for the virtual machine and the L-Server template, as follow:
When Dynamic Memory is Enabled
Free CPU capacity and memory size are calculated based on the CPU performance and initial memory size reserved for the virtual machine.
Free CPU capacity and memory size are calculated based on the CPU performance and initial memory size reserved for the L-Server template.
When Dynamic Memory is Disabled
Free CPU capacity/memory size are calculated based on the CPU performance/memory size reserved for the virtual machine.
The number of L-Servers that can be created is calculated based on the CPU reservation performance and memory capacity specified in the L-Server template.
[KVM]
When configured to calculate using a reservation value, free memory size is calculated based on the memory reservation capacity/memory size for the virtual machine. The free CPU capacity is not changed.
[Solaris Containers]
The number of CPUs and the CPU performance of an L-Server are displayed as "-" when the following conditions are met because the resources are not managed using Resource Orchestrator.
A cap value for the CPU has not been set in the non-global zone.
The non-global zone is managed using resource pools that are not the targets of management.
When the conditions are not met, the cap values of CPUs are used for the number of CPUs and the CPU performance.
For details, refer to "E.6.2 Preparations for Servers" in the "Design Guide CE".
When the number of CPUs and CPU performance are displayed as "-", the amount of resources used by an L-Server will be calculated using 0.
When something other than "-" is displayed for the number of CPUs and CPU performance, those values are used for calculation.
The memory size of an L-Server is displayed as "-" when a cap value of memory has not been set in a non-global zone.
When a cap value has been set, the value is set for the memory size of an L-Server.
When memory size is displayed as "-", the amount of resources used by an L-Server will be calculated using 0.
When something other than "-" is displayed for memory size, that value is used for calculation.
When configured to calculate using a reservation value, free CPU capacity and memory size of the virtual machine are not changed.
*3: This does not include the overhead used for the VM host.
*4: This includes not only the resources for active virtual machines, but also those of resources of stopped virtual machines.
[VMware]
This includes the overhead memory used for the virtual machine.
The resources of VMware FT secondary virtual machines are included.
*5:
[VMware]
This is the resource capacity secured when VMware HA admission control is enabled. This is calculated according to the policy of the admission control. Formulas for individual policies are as follows:
When the policy is share
Total_resource_capacity (*3) multiplied by the share (%)
When the policy is the VM host corresponding to the spare server
Total_resource_capacity (*3) multiplied by 100 (%)
When the policy is a VM host not corresponding to the spare server
Total_resource_capacity (*3) multiplied by 0 (%)
When the policy is slots
Total_resource_capacity (*3) multiplied by 0 (%)
The reservation capacity for the VM host is not secured with the following policies. If an L-Server is deployed with those policies, the L-Server may not be powered ON due to a shortage of resources.
When the policy is the spare server and multiple VM hosts are defined for the spare server
When the policy is slots
*6: This includes not only the resources for active L-Servers, but also those of resources of stopped L-Servers.
*7: Images include cloning images and snapshots. However, the size of images is not displayed.
[Xen]
When using RHEL5-Xen on the managed server, refer to "C.4.7 Advisory Notes for RHEL5-Xen Usage" in the "Setup Guide CE".
*8:
[VMware]
This does not include the overhead memory allocated when creating a virtual machine from an L-Server template.
Therefore, the displayed number of L-Servers may not be able to be created.
In display the converted number of L-Servers to the VM pools and storage pools, the number of L-Servers that can be created is as follows by specify VM type of virtual L-Server template.
When VM type is specified for the L-Server template
The number of L-Servers that can be created is displayed to the resource that corresponds to the specified VM type.
It is always displayed to the resource that does not correspond to the specified VM type, "0".
When VM type is not specified for the L-Server template
It does not depend on the VM type, and the number of L-Servers that can be created is displayed.
For the definition of the L-Server template, refer to "13.2.2 Virtual L-Server Templates" in the "Reference Guide (Command/XML) CE".
