![]() ![]() Note the total amount of memory, processors and processor clock cycles available per server. If three of those servers are redundant for highly resilient workload deployments, you'll wind up with seven: 10 servers total, minus three servers held for failover or redundancy-effective servers to supply compute resources. If you have 10 servers with no redundant nodes, there is a total of 10 servers available. This is the total number of servers minus the number of redundant servers. Collaborate with procurement specialists in your organization when completing such summaries.Īfter adding up the costs of your virtualized data center hardware and software deployment, the next step is to determine the computing capacity the deployment can provide to VMs.Ĭontinuing with the above example, you know the storage array will provide up to 512 TB, and now you must determine the effective number of servers. The table below displays cost examples and summarizes cost and time relationships. Actual costs can vary dramatically depending on the products selected and the specific terms extended by each vendor. Here's an example of a 10-server deployment with one large 512 TB storage array - such as an HPE 3PAR StoreServ 8000 or 9000 storage system - and a single management tool with annual updates. This number represents the total costs of your virtual hardware and software deployment. ![]() Next, multiply the fixed and recurring costs per server over the lifecycle by the total number of servers involved in the deployment. Likewise, a $2,000 annual management database cost for the deployment will come to $6,000 after a three-year period. Individual organizations might use longer or shorter lifecycles depending on their business plans and needs.Ī $10,000 fixed cost for a server - such as a Dell PowerEdge R6625 or R7625 rack server - will remain the same over three years, whereas an annual network connectivity cost of $500 will amount to $1,500 per server over the course of the lifecycle. For example, a three-year lifecycle means you plan to operate the equipment or software for three years before repurposing or retiring it. Multiply the annual recurring costs per server by the expected deployment lifecycle. Your organization might carry more or fewer costs, so adjust this list accordingly. Recurring annual costs per server might include network connectivity, storage connectivity, OS and management software maintenance, and routine system hardware maintenance. Start any VM cost estimate by calculating the total fixed and recurring costs of virtual server deployment.įixed costs per server might include physical servers physical storage, such as storage arrays hypervisor licenses, such as VMware vSphere OS licenses, such as Windows Server 2022 Datacenter edition and management software, such as VMware vCenter. Use the examples in this cost guide to learn how to calculate the cost of a VM instance. These calculations lay the foundations for cloud-based VM management tasks, such as showback and chargeback. And although cost analysis might seem better left to the business side, IT experts and collaborative, interdisciplinary FinOps teams have all the details necessary to perform basic calculations. ![]() Calculating the cost of a VM requires a keen knowledge of computing costs, an understanding of computing capacity and insight into anticipated use. ![]()
