Information Update 23

System Security Screen

Table 1-6 lists new options for the PowerEdge 1950 III system.

NOTE: Systems that are shipping in China are not equipped with TPM.

CAUTION: Before enabling the TPM Security option, ensure that the operating

system supports TPM.

I/OAT DMA

Engine

(Disabled default)

Enables or disables the I/O Acceleration Technology (I/OAT)

option. When set to Enabled, I/OAT reduces system CPU

usage for applications that use TCP by offloading part of TCP

receive operation to the DMA engine.

System Interrupts

Assignment

(Standard default)

This field controls the interrupt assignment for PCI devices

in the system. When set to Distributed, interrupt routing is

swizzled to minimize IRQ sharing among devices.

Table 1-6. New System Security Screen Options

Option Description

TPM Security

(Off default)

Sets the reporting of the Trusted Platform Module

(TPM) in the system.

When set to Off (default), presence of the TPM is

not reported to the operating system.

When set to On with Pre-boot Measurements, the

system reports the TPM to the operating system and

stores the pre-boot measurements (compliant with

Trusted Computing Group standards) to the TPM during

POST.

When set to On without Pre-boot Measurements, the

system reports the TPM to the operating system and

bypasses pre-boot measurements.
