95th percentile is the value below which 95 percent of the data points fall.
By using the 95th percentile data, occasional bursts in load can be ignored to provide a more meaningful capacity demand, compared to average or peak utilization.
The total configured capacity of all VMs residing on a VM Host. In case of a Datastore, the allocated capacity is the total configured capacity of all the vDisks residing on a Datastore.
The time period for which the data is considered for optimization analysis.
The average network utilization in Megabits per second.
The sum of the average CPU utilization.
The sum of the peak CPU utilization.
The CPU clock speed (in gigahertz) for a VM and VM host.
The name of the virtual disk associated with a VM Host.
The type of virtual disk used. The virtual disk can either be Thin or Thick.
A Group is the logical grouping of the infrastructure present in the Data Center based on the deployment type. A Group can either be a Business Service, Business Application, Node Group, Datastore Clusters, VMware Clusters, or Custom Groups.
This field indicates whether the Cluster is a High Availability Cluster or not.
Headroom is the extra capacity that is made available on a VM so that in case of an overload there is always extra capacity to avoid complete breakdown of resources.
The total number of hosts.
This field indicates whether the host contains a VM which is associated with more than one Group.
The maximum CPU capacity allocated to the workload.
The maximum memory capacity allocated to the workload.
The sum of the average memory utilization.
The sum of the peak memory utilization.
The minimum guaranteed CPU capacity allocated to the workload.
The minimum guaranteed memory capacity allocated to the workload.
The server model for a VM and VM Host.
The number of cores if the workload is a physical machine. The number of virtual CPUs if the workload is a virtual machine.
The total number of available VM hosts.
A VM is oversized if the utilization is below the defined acceptable utilization level by a factor which is greater than the acceptable tolerance level.
The peak network utilization in Megabits per second.
A physical host is a physical system which has all the applications running on itself rather than hosting the applications on virtual machines.
The remaining CPU, memory, and virtual disk capacity, after optimization of Groups, expressed in terms of number of VMs. The number of VMs are calculated based on the size of the reference VM. The reference VM size is defined on the General tab in the Configurations View page.
The average time (in milliseconds) taken by the server to acknowledge each service request.
A host is said to be shared if it hosts VMs associated with more than one Group.
This field indicates whether the CPU speed has been normalized using the SPECint2006 Rate benchmarks.
SPECint2006 Rate benchmarks specify the standard CPU speeds for the different CPU models. HP SH Optimizer sends the CPU models for all the available CPUs along with the count of CPUs and the CPU speed for each CPU to the SPECint2006 Rate database incorporated in HP SH Optimizer.
Subscription of resources is the percentage of capacity allocated to a VM out of the total capacity reserved for the VM.
If you subscribe more than 100% capacity to a resource, then the resource is termed as oversubscribed.
A VM is undersized if the utilization is beyond the defined acceptable utilization level by a factor which is greater than the acceptable tolerance level.
The type of virtualization technology used for the workload.
The distribution of VMs per VM host.
A VM host is physical system which hosts one or more virtual machines with different applications running on each of the virtual machines.
The percentage of available CPU capacity allocated to VMs present on the VM hosts.
The allocated capacity of a VM host is defined as the sum of configured memory capacity of all the VMs present on the VM hosts.
The percentage of available memory capacity allocated to VMs present on the VM hosts.
The allocated capacity of a VM host is defined as the sum of configured CPU capacity of all the VMs present on the VM hosts.
The number of VM Hosts needed if SHO is used to right-size and place the VMs.
The type of data considered for VM placement. The data considered can either be peak, 95 percentile, or the configured capacity of the VM.
Any physical system or virtual machine is called a workload.
The type of workloads considered for optimization analysis. The workloads considered can be physical, virtual, or both.
The workload type; whether the workload is a physical workload or virtual workload.
Note: Only virtual workloads will be available for Clusters.
