Trusted Platform Module

Trusted computing is an industry initiative that provides a combination of secure software and

secure hardware to create a trusted platform. It is a specification that increases network

security by building unique hardware IDs into computing devices. The x240 implements TPM

Version 1.2 support.

The TPM in the x240 is one of the three layers of the trusted computing initiative as shown in

Table 5-16.

Table 5-16 Trusted computing layers

5.2.8 Local storage

The x240 compute node features an onboard LSI 2004 SAS controller with two small form

factor (SFF) hot-swap drive bays. These bays are accessible from the front of the compute

node. The onboard LSI SAS2004 controller provides RAID 0, RAID 1, or RAID 10 capability. It

supports up to two SFF hot-swap serial-attached SCSI (SAS) or Serial Advanced Technology

Attachment (SATA) hard disk drive (HDDs) or two SFF hot-swap solid-state drives.

Figure 5-14 shows how the LSI2004 SAS controller and hot-swap storage devices connect to

the internal HDD interface.

Local SAS and SATA HDDs and SSDs

The x240 type 8737 has support for up to two hot-swap SFF SAS or SATA HDDs or up two

hot-swap SFF solid-state drives (SSDs). These two hot-swap components are accessible

from the front of the compute node without removing the compute node from the chassis. See

Table 5-17 for a list of supported SAS and SATA HDDs and SSDs.

eXFlash storage

In addition, the x240 supports eXFlash with up to eight 1.8-inch solid-state drives combined

with a ServeRAID M5115 SAS/SATA controller (90Y4390). The M5115 attaches to the I/O

adapter 1 connector. It can be attached even if the Compute Node Fabric Connector is

installed. The Compute Node Fabric Connector is used to route the Embedded 10 Gb Virtual
