KEY FEATURES AND BENEFITS
Performance
The Cisco MCS 7845-I1 is a robust, highly available server platform designed to support today's unified communications applications. The Cisco MCS 7845-I1 includes such innovations as variable speed fan support, NetBAY cabling support, Light Path Diagnostics and Chipkill memory support. The Cisco MCS 7845-I1 occupies only 2RU rack space while providing the features most requested in a high availability server platform. At product introduction the Cisco MCS 7845-I1 will ship with dual Intel Xeon 3.4GHz processors and over time the processor speed will be increased as Intel retires the 3.4GHz processor and introduces new processors that will be supported by the Cisco MCS 7845-I1 chassis.
High Availability
High availability on the Cisco MCS 7845-I1 is achieved through the following mechanisms:
• Redundant hot-swap 625W power supplies
• Hot-swap SCSI hard drives configured using RAID 1
• Redundant hot-swap fans
Memory
The Cisco MCS 7845-I1 supports up to 16GB of DDR memory. The increased processor performance coupled with DDR memory allows customers to retrieve and process information fast and efficiently. DDR memory executes twice the number of operations per cycle than traditional synchronous dynamic RAM (SDRAM) memory, effectively doubling the data exchange rate between memory and processors.
Variable Speed Fan Support
The Cisco MCS 7845-I1 includes variable speed fans to reduce operating noise. Through the use of temperature sensors within the server, the speed of the fans is adjusted to maintain the proper cooling. This reduces the noise generated by the fans by operating them only when required and at a speed based upon the cooling requirements.
Advanced Connectivity Technology
The Cisco MCS 7845-I1 supports IBM's new NetBAY Advanced Connectivity Technology products that helps reduce Keyboard/Video/Mouse (KVM) costs by linking administrators' chain systems together with Category 5 cable. In addition to reducing overall costs, Advanced Connectivity Technology reduces bulk cable clutter, making servers accessible and serviceable in the rack.
Serviceability
Light Path Diagnostics
The Cisco MCS 7845-I1 is equipped with Light Path Diagnostics. Light Path Diagnostics provides a central information LED panel (visible without removing the cover) and individual LED lights throughout the system on items like memory dual in-line memory modules (DIMMs), Peripheral Component Interconnect (PCI) slots, power supplies and CPUs. IT can quickly view system status and service personnel can pinpoint a specific failing component, helping reducing downtime and service costs. This provides increased availability, because nontechnical personnel can report error conditions without removing the top cover and exposing vital components to further risk. If the system error LED on the front of the server is on, one or more LEDs inside the server or on the power supply will be on. These LEDs will help identify and locate problems with some server components. By following the path of lights, you can quickly identify the type of system error that occurred. The Cisco MCS 7845-I1 is designed so that any LEDs that are illuminated remain illuminated when the server shuts down as long as the AC power source is good and the power supply can provide +5 VDC to the server.
Light Path Diagnostics provide indication of failures for the following conditions:
• One or both power supplies are consuming power higher than maximum rating
• Power Supply 1 failure
• Power Supply 2 failure
• Error on Voltage Regulator Module
• One or both processors failed.
• Hardware configuration error occurred
• Memory error
• Non-maskable interrupt occurred
• Error occurred on the system board
• Service processor failure
• Error on adapter on PCI-X slots A, B or C
• Hard disk error occurred
• Fan failure or slow operation
• System temperature exceeded maximum rating
• Soft error occurred
• RAID controller error occurred
Enhanced Predictive Failure Analysis
The Cisco MCS 7845-I1 supports Enhanced Predictive Failure Analysis (PFA) on hot swap fans, power supplies, processors, and memory and voltage regulator modules. Through diagnostics the Cisco MCS 7845-I1 is able to anticipate failures in these devices and generate an alert, which allows IT to quickly replace the components before a failure actually occurs. An example of PFA is its ability to monitor variations in electrical input/output to the power supplies and cooling fans.
Tape Drive Support
The Cisco MCS 7845-I1 can support an optional 36-/72-GB universal-serial-bus (USB) external Digital Audio Tape (DAT) drive (part number DAT-USB-EXT-72=) or an optional USB rack-mount DAT drive (part number DAT-USB-RM-72=). This tape drive connects through one of the 4 USB 2.0 ports provided by the Cisco MCS 7845-I1 server.
