Inbuilt Virtualization
Inbuilt virtualization is an optional capability for Express5800/A1160 systems. This
capability enables a partition to boot with VMware Infrastructure 3. The partition contains
a USB drive with a preloaded copy of the embedded version of VMware ESX 3.5. The
USB drive is attached to the compatibility hardware of the partition. When a partition that
contains the USB drive is booted, the partition boots to VMware (unless a disk is in the
DVD drive).
The inbuilt virtualization option gives an enterprise the ability to always bring up a
partition in a virtualized environment.
Trusted Platform Module (TPM)
Note: The TPM is an optional component. Contact your sales representative to
determine if the cells in your system contain a TPM.
The TPM is a hardware security device that implements protected capabilities and
shielded locations, which are used to protect and report integrity measurements as
defined by the Trusted Computing Group specifications. The TPM also stores a limited
number of cryptographic keys used to authenticate reported measurements. The TPM
protected capabilities can include additional security functionality such as cryptographic
key management, random number generation, and sealing data to system state.
The TPM is mounted on the management board and attached to the low pin count (LPC)
bus (see Figure 4-2
). The LPC bus connects low-bandwidth devices to the CPU.
In a multiple-cell partition, only one TPM can be active at a time. The active TPM is in
the boot cell of the partition.
Your data center must use key management software to migrate any keys stored in the
TPM if the boot cell changes.
