95th Percentile
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.
Allocated Capacity
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.
Analysis Period
The time period for which the data is considered for optimization analysis.
Average Network Utilization
The average network utilization in Megabits per second.
CPU Average
The sum of the average CPU utilization.
CPU Cycles
The total CPU capacity.
CPU Peak
The sum of the peak CPU utilization.
CPU Speed (GHz)
The CPU clock speed (in gigahertz) for a VM and VM host.
Disk Name
The name of the virtual disk associated with a VM Host.
Disk Type
The type of virtual disk used. The virtual disk can either be Thin or Thick.
Groups
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.
HA Cluster
This field indicates whether the Cluster is a High Availability Cluster or not.
Headroom
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.
Host Count
The total number of hosts.
IsShared
This field indicates whether the host contains a VM which is associated with more than one Group.
Maximum CPU Entitlement
The maximum CPU capacity allocated to the workload.
Maximum Memory Entitlement
The maximum memory capacity allocated to the workload.
Memory Average
The sum of the average memory utilization.
Memory Peak
The sum of the peak memory utilization.
Minimum CPU Entitlement
The minimum guaranteed CPU capacity allocated to the workload.
Minimum Memory Entitlement
The minimum guaranteed memory capacity allocated to the workload.
Model
The server model for a VM and VM Host.
Number of Cores
The number of cores if the workload is a physical machine. The number of virtual CPUs if the workload is a virtual machine.
Number of Targets
The total number of available VM hosts.
Oversized VM
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.
Peak Network Utilization
The peak network utilization in Megabits per second.
Physical Hosts
A physical host is a physical system which has all the applications running on itself rather than hosting the applications on virtual machines.
Remaining Capacity if Optimized (Number of VMs)
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.
Response Time (ms)
The average time (in milliseconds) taken by the server to acknowledge each service request.
Shared Host
A host is said to be shared if it hosts VMs associated with more than one Group.
SPECint used for CPU Normalization
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
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.
Undersized VM
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.
Virtualization Technology
The type of virtualization technology used for the workload.
VM Density
The distribution of VMs per VM host.
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.
VM Hosts Allocated CPU Capacity
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.
VM Hosts Allocated Memory Capacity
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.
VM Hosts Required if Optimized
The number of VM Hosts needed if SHO is used to right-size and place the VMs.
VMs placed based on
The type of data considered for VM placement. The data considered can either be peak, 95 percentile, or the configured capacity of the VM.
Workload
Any physical system or virtual machine is called a workload.
Workload Filter
The type of workloads considered for optimization analysis. The workloads considered can be physical, virtual, or both.
Workload Type
The workload type; whether the workload is a physical workload or virtual workload. Note: Only virtual workloads will be available for Clusters.
