1.6 Reliability, availability, and serviceability

Three important server design features are reliability, availability, and serviceability (RAS).
The RAS features help to ensure the integrity of the data that is stored in the server, the
availability of the server when you need it, and the ease with which you can diagnose and
correct problems.
The server has the following RAS features:

1-6
Integrated Trusted Platform Module (TPM)
This integrated security chip performs cryptographic functions and stores private and
public secure keys. It provides the hardware support for the Trusted Computing Group
(TCG) specification. You can download the software to support the TCG specification,
when the software is available.
Large data-storage capacity and hot-swap capability
The server supports up to eight 1-inch (26 mm) slim-high, 2.5-inch hot-swap hard disk
drives that are connected to two SAS backplanes. With the hot-swap feature, you can add,
remove, and replace hard disk drives without turning off the server. For more
information, see "Installing a hot-swap hard disk drive"
Light path diagnostics
Light path diagnostics provides LEDs to help you diagnose problems. For more
information, see the section about light path diagnostics in the Problem Determination
and Service Guide.
PCI Express 2.0 adapter capabilities
The server has six slots for PCI Express 2.0 x8 adapters and one slot for PCI Express x16
adapters. For more information, see "Installing a PCI Express adapter".
Redundant connection
The addition of an optional network interface card (NIC) provides a failover capability to
a redundant Ethernet connection. If a problem occurs with the primary Ethernet
connection, all Ethernet traffic that is associated with the primary connection is
automatically switched to the redundant NIC. If the applicable device drivers are
installed, this switching occurs without data loss and without user intervention.
Redundant cooling and power capabilities
The redundant cooling of the fans in the server enables continued operation if one of the
fans fails. The server supports up to two hot-swap power supplies, which provide
redundant power for many server configurations.
ServeRAID support
The server supports ServeRAID controllers to create redundant array of independent
disks (RAID) configurations.
Symmetric multiprocessing (SMP)
The server supports up to four multi-core Intel Xeon microprocessors. One or more
multi-core microprocessors provides SMP capability.
Advanced memory features:
−
Single-bit memory error detection
−
Single-bit memory error hardware correction
−
Multi single-bit memory error recovery and corrections
−
Uncorrectable error (UE) detection
