Analyze the CPU utilization data:

Historical CPU utilization data indicates that peak CPU utilization never exceeds 50% on either physical host.

This implies that the existing physical CPUs are underutilized.

Calculate vCPU

ratio:

Given that peak utilization is only 50%, a conservative approach would be to use a lower vCPU to pCore ratio to avoid overcommitment and ensure performance.

Recommended ratio:

A 2:1 vCPU to pCore ratio is appropriate in this scenario to ensure that there is ample CPU capacity and to avoid potential performance bottlenecks.

Understanding FIPS 140-2 Level 2 Requirements:

FIPS 140-2 is a U.S. government standard that specifies security requirements for cryptographic modules. Level 2 adds requirements for tamper-evidence and role-based authentication.

Required Items for FIPS 140-2 Level 2 Compliance:

Self-Encrypting Drives (SEDs):

Explanation: SEDs automatically encrypt data at rest, meeting the encryption standards required by FIPS 140-2 Level 2.

To verify if all network cards associated with BridgeO are being used by nodes in an AHV cluster, you need to examine the network configuration and the network interface cards (NICs) on the hosts. The following menus in the Prism interface will provide the necessary information:

Host NICs tab in Hardware menu:

This tab provides a detailed view of all NICs available on each host in the cluster.

It shows the status, speed, and configuration of each NIC, which helps determine if all network cards are active and properly associated with BridgeO.

Host view in Network menu:

The Network menu under the Host view provides insights into the network configuration for each host.

It includes information on how NICs are bridged, VLAN assignments, and overall network topology, confirming if all NICs are effectively used and contributing to the bridge.

These menus collectively ensure that the administrator can verify the network setup and utilization of all network interfaces.
