TPM and TXT
Configuration through UCS Manager
Cisco UCS M-Series
Modular Servers introduces the following in Cisco UCS Manager Release 2.5(2):
The Trusted Platform
Module (TPM) is a component that can securely store artifacts, such as
passwords, certificates, or encryption keys, which are used to authenticate the
server. A TPM can also be used to store platform measurements that help ensure
that the platform remains trustworthy. Intel Trusted Execution Technology (TXT)
provides greater protection for information that is used and stored on the
server.
This release
supports TPM and TXT configuration on Cisco UCSME-2814 compute cartridges
through Cisco UCS Manager. TPM is enabled by default and TXT is disabled by
default.
Status inidications differ between TPM versions. For information on TPM flag definitions and enabling, activation, and taking
ownership of these hierarchies, specific to your implementation, refer to the TCG Trusted Platform Module Specification.
vNIC Placement
on Host Ports
vNIC can be placed
on one of the two host ports of the shared adapter. You can either explicitly
specify the host port for placement, or allow Cisco UCS Manager to
automatically assign vNICs to host ports. The host port placement of the vNIC
determines the order of the vNIC on the adapter. The vNICs placed on the first
host port will be enumerated first followed by the vNICs on the second host
port. In this release, vNIC placement on host ports is applicable only to Cisco
UCSME-1414 compute cartridges.
vNIC placement on
host ports is detailed in
Cisco UCS Manager GUI Configuration Guide, Release 2.2.
Support for up
to 4 LUNs Per Server
The modular servers
in Cisco UCSME-2814 compute cartridges include support for up to 4 LUNs per
server, of which up to 2 LUNs are bootable. The modular servers in Cisco
UCSME-1414 and UCSME-142 compute cartridges support up to 2 LUNs per server.
Cisco UCS M-Series
Modular Servers introduces the following in Cisco UCS Manager Release 2.5(1):
Modular Server
Architecture
Some of the main
features of the modular server architecture are as follows:
-
Compute
cartridges—Each slot in the new modular chassis can contain a compute
cartridge. Each compute cartridge can contain one or more servers.
-
Three-tuple
reference for modular servers—In the new architecture, compute servers are
contained within cartridges, which in turn are contained in a chassis. This
makes all references to Cisco M-Series servers take a three-tuple form—chassis-id/cartridge-id/server-id.
-
Centralized
resources—Resources such as storage, I/O, and storage controller are
centralized and hosted in the chassis.
-
Shared
adapter—The shared adapter is contained in the modular chassis. It is the
aggregate point for accessing network and storage resources for servers.
Storage
Profiles
Storage profiles
are introduced to provide flexibility in configuring the usage of centralized
storage resources.
Cisco System
Link Technology
The Cisco UCS
Virtual Interface Card (VIC) used in the Cisco UCS M-Series modular servers
provides multiple PCIe buses that connect to multiple servers simultaneously.
It utilizes the System Link Technology, which extends a PCIe bus to each of the
servers and creates a virtual device on the PCIe host interface for use by the
local CPU. The OS sees this virtual device as a local PCIe device, and I/O
traffic is passed up the host PCIe lanes, and mapped to the appropriate shared
resource-the local storage or the networking interface.
Virtual Storage
Controller
The virtual storage
controller provides access to virtual drives that are provided to the server
through the shared storage controller and hard drives in the chassis. The
virtual storage controller introduces a new PCIe device, known as a SCSI NIC
(sNIC), which is presented to the OS. The OS views these items as
locally-attached SCSI devices.
