Key Features and Benefits

Performance

The Cisco MCS 7835-I2 Unified Communications Manager Appliance is a robust, highly available server platform designed to support today's unified communications applications. It includes such innovations as variable-speed fan support, NetBAY cabling support, and Light Path Diagnostics and Chipkill memory support. Occupying only 2RU of space, the Cisco MCS 7835-I2 Unified Communications Manager Appliance provides the features most requested in a high-availability server platform. At product introduction, it includes an Intel Xeon 2.33-GHz processor, and the processor speed will be increased as Intel replaces the 2.33-GHz processor and introduces new processors.

High Availability

High availability on the Cisco MCS 7835-I2 Unified Communications Manager Appliance is achieved through the following mechanisms:

• Redundant hot-swap 835W power supplies

• Hot-swap Serial Attached SCSI (SAS) hard drives configured using RAID 1

• Redundant hot-swap fans

Memory

The Cisco MCS 7835-I2 Unified Communications Manager Appliance supports up to 48 GB of DDR2 memory. The increased processor performance coupled with DDR2 memory allows for quick, efficient retrieval and processing of information. 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 7835-I2 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, reducing 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 7835-I2 Unified Communications Manager Appliance supports IBM's new NetBAY Advanced Connectivity Technology products that help reduce Keyboard/Video/Mouse (KVM) costs by linking administrators' chain systems 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 7835-I2 is equipped with Light Path Diagnostics, providing a central information LED panel (visible without removing the cover) and individual LED lights throughout the system on items such as 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 identify the specific failing component, helping reduce downtime and service costs. Thus the Cisco MCS 7835-I2 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 help identify and locate problems with some server components. By following the path of lights, users can quickly identify the type of system error that occurred. The Cisco MCS 7835-I2 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 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

• Memory error

• Nonmaskable interrupt

• Error on the system board

• Service processor failure

• Error on adapter in PCI-X slots A, B, or C

• Hard-disk error

• Fan failure or slow operation

• ·System temperature exceeded maximum rating

• Soft error

• RAID controller error

Remote Management

The RSA II SlimLine adds accelerated graphics and delivers advanced control and monitoring features to manage your Cisco MCS 7845-I2 Unified Communications Manager Appliance at virtually any time, from virtually any place. The adapter card can be added to the server through a connector that connects to the planar. This adapter enables easy console redirection with text and graphics, and keyboard and mouse (operating system must support universal-serial-bus [USB]) support over the system management LAN connections. With video compression now built into the adapter hardware, it is designed to allow the greater screen sizes and refresh rates that are becoming standard in the marketplace. This feature allows the user to display server activities from power-on to full operation remotely, with remote user interaction at virtually any time. The embedded Web server provides remote control from any standard Web browser. No additional software is required on the remote administrator's workstation. For those users who are accustomed to a command-line interface (CLI), the administrator can also use the provided CLI from a Telnet session to perform some of the functions that they can perform from the Web server. The Remote Supervisor Adapter II SlimLine provides remote management and control of the system independent of the server status, in many cases even if the server is powered off or otherwise disabled.

Enhanced Predictive Failure Analysis

The Cisco MCS 7835-I2 supports Enhanced Predictive Failure Analysis (PFA) on hot-swap fans, power supplies, processors, and memory and voltage regulator modules. Through diagnostics, the Cisco MCS 7835-I2 anticipates failures in these devices and generates an alert, allowing service personnel 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.

DAT Support

The Cisco MCS 7835-I2 appliance can support an optional 36-/72-GB 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 7835-I2 appliance.
