SuperMicro - Control Fan Speed via IPMICFG (Command Line)

Issue:

Need to change the fan speed for SuperMicro servers.

Resolution:

  1. Download and extract IPMICFG on the target server
  1. Open CMD prompt as ADMIN
  2. Change Directory to the extracted folder, and drill down to the Windows\64bit folder
    1. EXAMPLE: cd c:\ADMIN\Installs\IPMICFG_1.29.0_build.181029\Windows\64bit\
  3. To view the current Fan Profile
    1. RUN: IPMICFG-Win.exe -fan 
  4. To change the current Fan Profile
    1. RUN: IPMICFG-Win.exe -fan x
      1. x can equal one of the following:
        1. 0 for Standard (BMC control of both fan zones, with CPU zone based on CPU temp (target speed 50%) and Peripheral zone based on PCH temp (target speed 50%))
        2. 1  for Full (all fans running at 100%)
        3. 3 for PUE2 Optimal (BMC control of the CPU zone (target speed 30%), with Peripheral zone fixed at low speed (fixed ~30%))
        4. 4 for Heavy IO (BMC control of CPU zone (target speed 50%), Peripheral zone fixed at 75%)
      2. EXAMPLE: To set fans to Standard
        1. RUN: IPMICFG-Win.exe -fan 0

Windows Update - Defer feature updates and Delivery Optimization

Issue:

You do not want Windows Machines in your AD environment to update automatically on Patch Tuesday 

Resolution:

  1. Create a new group Policy 
  2. Set Windows Components>Windows Update>Defer Windows Updates>Select when Feature Updates are received to: enabled
    1. Set Branch Readiness level to: Current Branch for Business (this feature is being deprecated soon, but it won't hurt to have it on)
    2. Set After a feature update is released, defer receiving it for this many days to: 30
  3. Set Windows Components>Delivery Optimization>Download Mode to: Enabled
    1. Set Download Mode to: Group 2 (Group 2 only allows the P2P sharing of an update on devices in the same Active Directory Site)
