• Light path diagnostics Light path diagnostics provides light-emitting diodes (LEDs) to help you diagnose problems. For more information, see the Intel® Server Compute Blade SBXD132 Hardware Maintenance and Troubleshooting Guide. • PCI Express PCI Express is a fully serial interface that can be used for universal connectivity for use as a chip-to-chip interconnect, I/O interconnect for adapters, and an I/O attachment point to Gigabit-networking devices. PCI Express bridges a PCI Express bus to a PCIX bus and converts the transactions on the PCI bus to transactions on the PCIX bus. Using the expansion card connector you can add additional LAN interfaces. The expansion card connector supports PCI-X 133 and bridges PCI Express into PCI-X 133. • Power throttling Each blade server is powered by two redundant power-supply modules. By enforcing a power policy known as power domain oversubscription, the SBCE unit can share the power load between two power modules to ensure efficient power for each device in the SBCE unit. This policy is enforced when the initial power is applied to the SBCE unit or when a blade server is inserted into the SBCE unit. You can configure and monitor the power environment by using the management module. For more information about configuring and using power throttling, see the managementmodule documentation or http://support.intel.com/support/. Reliability, Availability, and Serviceability Features Three of the most important features in server design are reliability, availability, and serviceability (RAS). These RAS features help to ensure the integrity of the data that is stored in the blade server, the availability of the blade server when you need it, and the ease with which you can diagnose and correct problems. The blade server has the following RAS features: • Advanced Configuration and Power Interface (ACPI) • Automatic error retry or recovery • Built-in monitoring for temperature, voltage, hard disk drives, and flash drives • x4 SDDC • Customer support center 24 hours per day, 7 days a week1 • Customer-upgradeable basic input/output system (BIOS) code and diagnostics • Diagnostic support of Ethernet controllers • ECC memory • ECC protection on the L2 cache • Error codes and messages 1. Service availability will vary by country. Response time will vary depending on the number and nature of incoming calls. 6 Intel® Server Compute Blade SBXD132 Installation and User's Guide
