Lenovo 3826 Preboot diagnostics program, High-performance graphics controller, Memory mirroring

Note: The server does not support Disk Operating System (DOS).

vPreboot diagnostics program

The preboot diagnostics programs are stored on the integrated USB memory. They collect and analyze system information to aid in diagnosing server problems. The diagnostics programs collect the following information about the server:

–System configuration

–Network interfaces and settings

–Installed hardware

–EasyLED status

–Service processor status and configuration

–Vital product data, firmware, and UEFI (formerly called BIOS) configuration

–Hard disk drive health

–RAID controller configuration

–Event logs for RAID controllers and service processors

The diagnostics programs create a merged log that includes events from all collected logs. The information is collected into a file that you can send to service and support. Additionally, you can view the information locally through a generated text report file. You can also copy the log to a removable media and view the log from a Web browser.

For additional information about diagnostics, see the Hardware Maintenance Manual.

vHigh-performance graphics controller

The server comes with an onboard high-performance graphics controller that supports high resolutions and includes many performance-enhancing features for the operating-system environment.

vIntegrated network support

The server comes with an integrated dual-port Broadcom Gigabit Ethernet controller, which supports connection to a 10 Mbps, 100 Mbps, or 1000 Mbps network. For more information, see “Enabling the Broadcom Gigabit Ethernet Utility program” on page 151.

vIntegrated 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. You can enable TPM support through the Setup Utility under the System Security menu option.

vLarge data-storage capacity and hot-swap capabilities

Some hot-swap server models support eight slim-high, 2.5-inch hot-swap hard disk drives or four 3.5-inch hot-swap hard disk drives (depending on the model). With the hot-swap feature, you can add, remove, or replace hard disk drives without turning off the server.

vLarge system-memory capacity

The server supports up to 48 GB (reduced to 24 GB in mirroring mode) of system memory. The memory controller supports error correcting code (ECC) for up to 12 industry-standard PC3-10600R-999 (single-rank or dual-rank), 800, 1067, and 1333 MHz, DDR3 (third-generation double-data-rate), registered, synchronous dynamic random access memory (SDRAM) dual inline memory modules (DIMMs).
