IBM Support Center. Additionally, you can view the server information locally through a generated text report file. You can also copy the log to removable media and view the log from a Web browser. v 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. v Redundant cooling and power capabilities The redundant cooling of the fans in the server enable 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. v ServeRAID support The server supports ServeRAID controllers to create redundant array of independent disks (RAID) configurations. v Symmetric multiprocessing (SMP) The server supports up to four multi-core Intel Xeon microprocessors. One or more multi-core microprocessors provides SMP capability. v Systems-management capabilities The server supports an IBM Remote Supervisor Adapter II. When this adapter is used with the systems-management software that comes with the server, you can manage the functions of the server locally and remotely. The Remote Supervisor Adapter II also provides system monitoring, event recording, and dial-out alert capability. 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: v Active memory v Automatic BIOS recovery (ABR) v Automatic error retry and recovery v Automatic restart after a power failure v Availability of microcode and diagnostic levels v Backup basic input/output system (BIOS) switching under the control of the service processor v Baseboard management controller (service processor) v Built-in, menu-driven electrically erasable programmable ROM (EEPROM) based setup, system configuration, and diagnostic programs v Built-in monitoring for fan, power, temperature, voltage, and power-supply redundancy v Error codes and messages v Error correcting code (ECC) L2 cache and system memory v Fault-resistant startup v Hot-swap hard disk drives v IBM Director workgroup-hardware-management tool v Information and light path diagnostics LED panels 8 IBM System x3850 M2 and System x3950 M2 Types 7141 and 7233: User's Guide
