Cluster Cost Computation with Allocation Model

You can now use the allocation model to compute the cost of clusters in vRealize Operations , earlier the cluster cost computation was based on the cluster utilization. When you perform cost computation using the allocation model, you can set the over commit ratio for CPU, RAM, and storage.

Note: The allocation ratio can be set at both cluster level and datastore cluster level. You can also mention the storage base rate, which will displayed at the datastore level.

Table 1. Cluster Base Rate Computation with Allocation Model

Base Rate	Formula
vCPU Base Rate	vCPU base rate = B1 = (Cost attributed to CPU) / (Number of vCPUs in a cluster)
RAM Base Rate	RAM base rate = B2 = (Cost attributed to RAM) / Number of vRAMs in a cluster) Note: The cost computation is based on Over Commit ratio. If the Over Commit ratio is 1:4, and total cores in cluster are 6, then vCPU count = 24, in case if the allocated vCPU exceeds this targeted number, then the maximum value is selected.

Table 2. Virtual Machine Cost Computation with Allocation Model

Cost	Formula
Virtual Machine Cost	Virtual machine cost = (Number of vCPU allocated x B1 of cluster it belongs to) + Number of vRAMs allocated x B2 of cluster it belongs to) + storage cost + direct cost. Note: Storage allocated represents the Storage Base Rate based on allocation.
