• 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-add/hotswap memory, hot-swap HDDs, adapters, and the integrated optional ServeRAID-MR10k and Remote Supervisor Adapter II. This can save a servicer significant time. 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 and xSeries 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%. 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 centrally managed. Equally importantly, with ACT—unlike some other offerings— everything is done externally via cabling; no special adapters are required. The illustration below shows a sample ACT configuration: Please see the Legal Information section for important notices and information. Combining high-performance architecture with high-performance Xeon processors Directly Via Daisy-Chain • Max.16 servers per port All CAT5, 5e, 6 Via Secondary cabling Switch Advanced Systems Management Capabilities The x3850 M2 and x3950 M2 have a high level of systems management capabilities that are well-suited to remote locations as well as to stand-alone environments. Features include the Baseboard Management Controller (BMC), IBM Systems Director Active Energy Manager for x86 (formerly known as PowerExecutive), Automatic Server Restart, Wake on LAN® support, PXE support, text console redirect, Predictive Failure Analysis, IBM Systems Director, IBM Systems Director Active Energy Manager for x86, and the Remote Supervisor Adapter II. The BMC provides industry-standard Intelligent Platform Management Interface (IPMI) 2.0compliant systems management. It provides a number of important system functions, including: • Monitoring of system and battery voltage, system temperature, fans, power supplies, processor and DIMM status • Fan speed control • Product ID and Family ID detection • Highly secure remote power on/off • System reset control • NMI/SMI detection and generation • System diagnostic LED control (power, HDD, activity, alerts, heartbeat) • IPMI over LAN • Serial Over LAN • Proxy server support • LAN messaging and alerting • Text console redirection over LAN • VLAN support • Enhanced authentication and encryption algorithms (RMCP+, SHA-1, AES) • Local update of BMC firmware • Firmware firewall • Support for IPMI v2.0 compliant management software (e.g., xCAT) • Other mandatory and optional IPMI BMC functions The BMC alerts IBM Systems Director to anomalous environmental factors, such as voltage and thermal conditions—even if the server has failed. The IBM Remote Supervisor Adapter II provides additional systems management capabilities, including: • Graphical console redirection over LAN • Web-based out-of-band control • Windows “blue screen” capture • Remote virtual floppy and CD-ROM • High-speed remote redirection of PCI video, keyboard and mouse Please see the Legal Information section for important notices and information. Combining high-performance architecture with high-performance Xeon processors • SSL (Secure Socket Layer) and LDAP (Lightweight Directory Access Protocol) support Automatic Server Restart (ASR) helps reduce downtime by restarting the server automatically in the event of a system lockup. ASR technology is a combination of hardware circuitry tied into the server’s system reset function and a device ...
