Virtual Machine Resources
Resources are the components that exist on a virtual machine. Components that you can view include datastores and VMDKs.
Datastores
A data store is a storage location for files that are related to a virtual machine. A storage location can be a VMFS volume, a directory on network-attached storage, or a local file system path. To view information about the data stores that are available on a virtual machine, click Datastores (1) in the left pane. The number in parentheses shows the number of datastores that are available on the virtual machine. The following information is available for each data store:
- Available Datastore Capacity (GiB)
- The capacity that is unused on a datastore.
- Available File System Capacity (GiB)
- The unused storage space on a file system.
- Cluster
- If the host is a member of a cluster, the cluster name is displayed. If the host is not a member of a cluster, no information is displayed.
- Datastore Capacity (GiB or GB)
- Amount of storage space that is assigned to a data store, which is measured in gibibytes (GiB) or gigabytes (GB). A GiB is a base-2, binary unit of measurement equal to 1,073,741,824 bytes. A GB is a base-10, decimal unit of measurement equal to 1,000,000,000 bytes.
- Drives
- The name of the drive on the host where the datastore is located. Click the name of the drive to view the properties notebook for the disk. If data was not collected for the storage system that the drive is on, this column is blank.
- File System
- The name of the file system or mount point on a host or hypervisor. If a file system is not mounted, no value is shown.
- File System Capacity (GiB)
- The storage space on a file system.
- Name
- The name of the data store that is mapped to the drive.
- Pool
- The name of the storage pool that contains the storage volume. Click the name of the pool to view the properties notebook for the pool. If there are multiple pools, the number of pools is shown.
- Status
- The status of a datastore.
- Storage System
- The name of the storage system that provides storage space for the datastore. Click the name of the storage system to view more information about it. If there are multiple storage systems, the number of storage systems is shown.
- Swap Space
- Shows whether a data store is a swap volume. A swap volume provides virtual memory that extends the real memory (RAM) on a host.
- Type
- The type of file system. You can use IBM Storage
Insights Pro to monitor the following types of file systems:
- VMFS
- VMFS 3
- VMFS 5
- VMFS 6
- NFS
- vSAN
- vVOL
- Used Capacity (%)
- The percentage of space that is used on a file system. The following formula is used to calculate this value:
- Used Datastore Capacity (GiB)
- The amount of storage space that is used on a datastore.
- Used File System Capacity (GiB)
- The storage capacity that is being used on a file system. On some UNIX file systems, this value does not include capacity that is reserved by the
operating system, which is known as overhead. IBM Storage
Insights Pro does not include the following file
systems when it calculates this value:
- File systems that are mounted remotely and are not identified to a network-attached storage server.
- File systems that are not mounted.
- Virtual Machines
- The number of virtual machines that are using the datastore. A datastore might be assigned to more than one virtual machines. When one virtual machine name is displayed, clicking the name will open the properties of the virtual machine. When multiple virtual machines are detected, clicking the count will open a table listing the virtual machines.
- VMDKs
- The path to the VMDK on the data store. Click the path to view the VMDKs tab in the properties notebook for the data store. If there are multiple VMDKs on the data store, the number of VMDKs is shown.
- Volumes
- The name of the storage volume that provides storage space for the datastore. Click the name of the volume to view the properties notebook for the volume. If there are multiple volumes that provide storage space, the number of volumes is shown.
VMDKs
A virtual machine disk (VMDK) stores the contents of the hard disk drive for a virtual machine. To view information about the VMDKs that are available on a virtual machine, click VMDKs (1) in the left pane. The number in parentheses shows the number of VMDKs that are available on the virtual machine. The following information is available for each VMDK:
- Datastore
- The data store that contains the VMDK. Click the name of the data store to view the properties notebook for the data store.
- Drive
- The name of the drive on the host where the VMDK is located. Click the name of the disk to view the properties notebook for the disk. If data was not collected for the storage system that the drive is on, this column is blank.
- Path
- The location of the VMDK for the virtual machine. The path includes the name of the data store.
- Pool
- The name of the storage pool that contains the storage volume. Click the name of the pool to view the properties notebook for the pool. If there are multiple pools, the number of pools is shown.
- Size (GiB)
- The size of the VMDK on the data store.
- Storage System
- The name of the storage system or NAS server that provides storage space for the VMDK. Click the name of the storage system to view more information about it. If there are multiple storage systems, the number of storage systems is shown.
- Used Capacity (GiB)
- The amount of storage space that is used on a VMDK.
- Virtual Machine
- The name of the virtual machine that is associated with the VMDK. If the virtual machine is managed by a an agentless server, click the name of the virtual machine to view the server information. If the virtual machine was discovered, click the name of the virtual machine to view the properties notebook for the virtual machine.
- Virtual Machine Drive
- The name of the drive that is presented in the guest operating system (OS) on the virtual machine. The name is available if a Storage Resource agent is deployed. Click the name of the drive to view the properties notebook for the drive.
