At the Workload step of the creation wizard, you specify the levels of performance, availability, and hardware capacities you want provisioned for this VI workload domain.

About this task

Based on your selections, SDDC Manager will determine:

  • The number of hosts that it needs to fulfill those selections

  • Which specific hosts in your environment are available and appropriate to fulfill those selections

  • The virtual infrastructure features and their specific configurations that are needed to fulfill those selections

Note:

You can modify the vSAN configuration in vSphere without negatively affecting the Cloud Foundation configuration.

Procedure

  1. Specify the performance level.

    Option

    Description

    Low

    With this choice, the following vSAN parameters are used:

    • Number of disk stripes per object: 1

    • Flash read cache reservation: 0%

    • Force provisioning (in spite of non-compliance): False

    • Object space reservation: 40%

    Balanced

    With this choice, the following vSAN parameters are used:

    • Number of disk stripes per object: 1

    • Flash read cache reservation: 0%

    • Force provisioning (in spite of non-compliance): False

    • Object space reservation: 70%

    High

    With this choice, the following vSAN parameters are used:

    • Number of disk stripes per object: 4

    • Flash read cache reservation: 0%

    • Force provisioning (in spite of non-compliance): False

    • Object space reservation: 100%

    Note:

    Hosts to be used for a high performance workload domain must contain at least 3 capacity tier disks.

  2. Specify the level of availability you want configured for this virtual environment.

    The availability level determines the level of redundancy that is set for the assigned resources.

    Option

    Description

    None

    With this choice, the following vSAN parameters are used:

    • Number of failures to tolerate: zero (0).

    Because vSAN requires a minimum of three hosts by default, three hosts are assigned to the virtual infrastructure.

    Normal

    With this choice, the following vSAN parameters are used:

    • Number of failures to tolerate: one (1).

    Because vSAN requires a minimum of three hosts by default, three hosts are assigned to the virtual infrastructure.

    High

    With this choice, the following vSAN parameters are used:

    • Number of failures to tolerate: two (2).

    Because vSAN requires a minimum of five hosts by default for this setting, five hosts are assigned to the virtual infrastructure.

  3. Type capacities for the CPU, memory, and storage for the resource pool that will be created and assigned to this virtual environment.
