This enables quick replacement of the component, which helps increase server uptime and lower operating costs. The front of the server has an LED indicator light to show possible component failures. If the front LED indicates an error condition, by pressing a button on the front of the server an LED panel will pop out and drop down for easy viewing without the need to open the server cover or remove the server from the rack. The light path diagnostics panel tells the servicer which component requires attention. In addition, many components have their own identifying LEDs. For example, each of the eight memory modules has an LED next to the socket, as do both processors, all adapter slots, all fans, all power supplies, the voltage regulator module and the service processor, allowing the servicer to easily identify exactly which component needs servicing. By following the “light path,” the component can be replaced quickly, and without guesswork. (Note: In the event of a failed DIMM, the system will restart and mark the DIMM as bad while offline, thus allowing the system to continue running, with reduced memory capacity, until serviced.) Hot-Swap/Redundant Components System availability is maximized through the extensive use of hot-swap and redundant components, including: • Redundant memory protection (with memory mirroring enabled) • Hot-swap, redundant hard disk drives (with RAID-1/10 protection standard and three other RAID levels optional) • Hot-swap, redundant power supplies • Hot-swap, redundant cooling fans Other Features • Four USB 2.0 ports — Provides flexibility to add high-speed external devices. The USB 2.0 specification supports up to 480Mbps transfer rates. (Note: Not all USB 2.0 devices are capable of achieving this rate.) Two ports are provided on the front of the server and four on the back. USB ports can be used for pre-boot to an external drive, also for KB/mouse • Embedded hypervisor via a USB connector on the motherboard) activated with an optional 2GB USB key; for supporting VMware ESXi for virtualization (available 2Q/09) • Virtual Media Key — This optional full-function systems management adapter adds local and remote management functions without consuming a valuable adapter slot. • Dual video ports — A Matrox G200eV SVGA video controller provides up to 1024x768 resolution, with a color depth of 32 bits at 85Hz refresh rate. To simplify local systems management, one video port is provided on the front of the unit and one on the back. • Toolless slides — Allows quick rack installation and quicker upgrade and servicing of the server. • Toolless chassis — The cover can be opened without tools, and many components can be removed and replaced without tools, including the CD-RW/DVD combo drive, hot-swap HDDs, plus PCI, PCI-X and PCIe adapters, as well as the integrated ServeRAID BR10i and Virtual Media Key. This can save a servicer significant time. Please see the Legal Information section for important notices and information. Leadership enterprise server with significantly lower cost of ownership in a highly available and expandable, rack-dense, 1U dual-socket server Rack Cable Management and KVM Console Switching IBM Advanced Cabling Technology (ACT) is an optional feature that offers many advantages over standard KVM cabling across the entire System x product line. So now you can interconnect all of your servers with one smart cabling architecture. ACT cabling eliminates the need for one- to-one direct connections between each server and a KVM switch by using a daisy-chain approach. The snarl of cabling behind most racks is at best inconvenient to work around and at worst an expensive logistical nightmare, requiring the rewiring of servers, PDUs, KVM switches, and other equipment whenever a rack server is added or removed. Even worse, the veil of cables blocks rack airflow and can actually contribute to equipment failure due to overheating. ACT cabling is the solution for reducing behind-the-rack cabling by as much as 87%. The illustration below shows a sample ACT configuration: Directly Via Secondary Switch Via Daisy-Chain • Max.16 servers per port All CAT5, 5e, 6 cabling Conventional cabling has bulky KVM cables exiting each server, which then connect to a KVM switch. The cables exiting a series of KVM switches must then be aggregated via additional KVM switches and PDUs, which only increases the number—and cost—of cables, KVM switches and PDUs. Instead, the daisy-chain approach of ACT cabling uses readily available, inexpensive CAT5 and 6 cabling to considerably reduce the number of cables, KVM switches, and PDUs needed, rather than increasing them. If a server is removed or added, no complicated rewiring is needed. One cable connects the first server in the rack to the next, and so on. Up to 16 servers form a chain; up to 8 chains can connect to one Local Console Manager (LCM); 16 LCMs can connect to one Global Console Manager (GCM). In this manner, up to 2,048 servers can be centra...
