Scenario

  • You run two sets, or banks, of 50 virtual machines (VMs) in each bank.
  • The first bank of VMs runs Windows Server under Hyper-V virtualization.
  • The second bank of VMs runs Linux under VMware virtualization.
  • There's also a storage area network (SAN) with 60 TB of disk storage.
  • You consume an estimated 15 TB of outbound network bandwidth each month.
  • There are also a number of databases involved, but for now, you'll omit those details.

Steps

Define your workloads

Enter the specifications of your on-premises infrastructure into the TCO Calculator.

  • Go to the TCO Calculator.
  • Under Define your workloads, select Add server workload to create a row for your bank of Windows Server VMs.
  • Under Servers, set the value for each of these settings:
    • Name Servers: Windows VMs
    • Workload: Windows/Linux Server
    • Environment: Virtual Machines
    • Operating system: Windows
    • Operating System License: Datacenter
    • VMs: 50
    • Virtualization: Hyper-V
    • Core(s): 8
    • RAM (GB): 16
    • Optimize by: CPU
    • Windows Server 2008/2008 R2: Off
  • Select Add server workload to create a second row for your bank of Linux VMs. Then specify these settings:
    • Name Servers: Linux VMs
    • Workload: Windows/Linux Server
    • Environment: Virtual Machines
    • Operating system: Linux
    • VMs: 50
    • Virtualization: VMware
    • Core(s): 8
    • RAM (GB): 16
    • Optimize by: CPU
  • Under Storage, select Add storage. Then specify these settings:

    • Storage type: Local Disk/SAN
    • Disk type: HDD
    • Capacity: 60 TB
    • Backup: 120 TB
    • Archive: 0 TB
  • Under Networking, set Outbound bandwidth to 15 TB.
  • Select Next.
