Specify infrastructure details

Stay organized with collections Save and categorize content based on your preferences.

On the Infrastructure page, based on the infrastructure data that you have about your current on-premises environment, enter your best estimates for CPU, memory, and storage. Enter the total aggregate count of memory across all systems in the datacenter. Also, specify the total aggregate storage footprint, including all direct-attached storage (DAS) and network-attached storage (NAS).

Specify infrastructure details

  1. In the Total vCPUs to be migrated section, in the Number of vCPUs field, enter the number of x86 vCPUs to be migrated to Google Cloud.

    The Data center memory required field is automatically updated based on the default compute to storage ratio, which is 1:4. If you want to reduce or increase the storage, see the instructions on how to modify this ratio in this document.

  2. If you want to include non-x86 infrastructure in your cost estimate, in the Total vCPUs to be migrated section, select Include non-x86 infrastructure. Then, specify non-x86 infrastructure details in the additional fields that appear.

  3. In the Storage currently in use in your data center(s) section, specify the following details:

    • In the Total storage (TB) field, enter the total storage, in TB, currently in your data center.

    • In the % File Storage, % Block Storage, and % Object Storage fields, enter the percentage of total storage used by file, block, and object storage respectively.

    • Under Storage location, select the locations where you want your storage to be located. If you select multiple locations, new fields appear where you need to specify the percentage distribution of storage for every location.

  4. From the currency list on the right, choose the currency you want to use for your cloud cost estimate.

  5. To specify enterprise workload details, click Next.

Specify non-x86 infrastructure details

  1. To migrate mainframes, in the Mainframe section, select I am migrating mainframes and follow these steps:

    1. In the Mainframe MIPS # field, enter the mainframe million instructions per second capacity.

    2. Under Mainframe Colocation or Rehosting (Emulation), choose whether you want to use Colocation or Rehosting for your mainframes.

  2. To migrate Unix cores, follow these steps:

    1. In the Number of UNIX vCPUs field, enter the number of Unix vCPUs you want to migrate.

    2. In the UNIX vCPU distribution section, specify the percentage distribution of the Unix cores in the following fields:

      • % Solaris: Enter the percentage of total Unix cores you want to migrate as Solaris vCPUs.

      • % IBM Power: Enter the percentage of total Unix cores you want to migrate as IBM Power vCPUs.

      • % HP-UX: Enter the percentage of total Unix cores you want to migrate as HP-UX vCPUs.

      • % Other: Enter the percentage of total Unix cores you want to migrate as other Unix vCPUs.

  3. In the Unix infrastructure type field, choose if you want a Managed Service Provider for your Unix vCPUs or you want them to be Emulated.

(Optional) Modify infrastructure assumptions

  1. To modify the default assumptions used to calculate your cloud cost estimate, click Edit details.

  2. In the Refine estimate details dialog that appears, modify the default assumptions as you need.

  3. To save the settings and exit the dialog, click Save.
