NO TICE
Configure fan modules based on the following guidelines. Otherwise, compute nodes can
power off due to insufficient heat dissipation.
Configure fan modules based on the following guidelines:
l
If a chassis houses eight or fewer half-width compute nodes or four or fewer full-width
compute nodes, install all fan modules except fan modules 5, 6, 11, and 12.
l
If a chassis houses more than eight half-width compute nodes or more than four full-
width compute nodes, install all fan modules.
2.7 Security
2.7.1 Compute Node
Compute nodes support security solutions based on the Trusted Platform Module (TPM).
The TPM is a security chip that complies with the Trusted Computing Group (TCG) TPM
specification. As a hardware-based system security module, TPM 1.2 supports data
encryption, key protection, identity authentication, and internal resource access protection.
TPM V1.2 is currently available.
The TPM is installed on a compute node mainboard and connects to the mainboard over a
port. You can access a compute node with the TPM in a specific way only after authorization
and authentication are completed, which ensures user data security in the aspect of hardware.
