Modifying the ESXi host parameters

To ensure that the SCVM runs optimally on the VMware ESXi host, you need to modify the parameters of the ESXi host.

Procedure

1. Return to the System Customization menu, select Troubleshooting Options > Enable SSH, and then press Enter to enable the SSH service.

2. Connect to the ESXi host via the SSH service and log in to the ESXi host with the root account. Then, run the following commands in sequence on the ESXi host:

   esxcfg-advcfg -s 30 /NFS/HeartbeatTimeout
   esxcfg-advcfg -s 64 /NFS/MaxVolumes
   esxcfg-advcfg -s 1 /Misc/APDHandlingEnable
   esxcfg-advcfg -s 32 /Net/TcpipHeapSize
   esxcfg-advcfg -s 1536 /Net/TcpipHeapMax
   esxcfg-advcfg -s 1 /UserVars/SuppressShellWarning

3. (Optional) To enable hot-plug for NVMe passthrough hard disks, run the following command on the ESXi host to set the ESXi VMkernel parameters.

   esxcli system settings kernel set -s maxIntrCookies -v 4096

4. Reboot the ESXi host.

   Note:

   Since configuring PCI passthrough later will also require rebooting the ESXi host, you can skip the reboot now and perform it when configuring PCI passthrough.

5. Refer to the above steps to modify the parameters of the ESXi host for other nodes.
