The Cisco Unified Communications portfolio is an important part of the Cisco Business Communications Solution-an integrated solution for organizations of all sizes that also includes network infrastructure, security, and network management products; wireless connectivity; and a lifecycle services approach-along with flexible deployment and outsourced management options; end-user and partner financing packages; and third-party communications applications.
PRODUCT OVERVIEW
The Cisco® MCS 7835-H1 Unified CallManager Appliance (MCS 7835-H1) is a high-availability server platform for Cisco Unified CallManager 5.0 and an integral part of a complete, scalable architecture for a new generation of high-quality IP Communications solutions for enterprise data networks. Delivering the high performance and availability that today's enterprise networks demand, this solution is easy to deploy and highly cost-effective. The server appliance is preinstalled with an operating system and Cisco Unified CallManager 5.0; it is fully operational upon startup, requiring entry of just a few configuration items such as IP address and domain. At just 2 rack units (2RU) high, the Cisco MCS 7835-H1 offers tremendous power in a low-profile chassis that minimizes rack space. It supports up to 2500 IP phones per appliance and up to 10,000 IP phones in a cluster configuration, and includes the following features and components:
• Intel Xeon 3.4-GHz (or higher) processors, an 800-MHz front side bus (FSB), and 2 MB of Layer 2 cache
• PC2-3200R 2-GB 400-MHz Double Data Rate 2 (DDR2) memory with online spare capabilities
• Integrated Ultra320 Smart Array 6i Redundant Array of Independent Disks (RAID) Controller with 64-MB read cache plus 128-MB battery-backed write cache
• Support for Integrated Lights Out (iLO) server management
• Support for up to six 1-inch Ultra320 Small Computer System Interface (SCSI) hot-plug hard drives or for five hot-plug hard drives and one Digital Audio Tape (DAT) hot-plug tape drive
• Hot-plug redundant power supplies
• Hot-plug redundant fans
KEY FEATURES AND BENEFITS
Performance
The Cisco MCS 7835-H1 Unified CallManager Appliance is a robust, highly available server platform designed to support today's IP Communications applications; it uses an Integrated Smart Array 6i Controller with a 64-MB cache to provide onboard RAID support without using one of the peripheral-component-interface (PCI)-X slots on the server. The appliance occupies only 2RU of space while providing the features most requested in a high-availability server platform. At product introduction, the Cisco MCS 7835-H1 includes an Intel Xeon 3.4-GHz processor, and over time the processor speed will be increased as Intel retires the 3.4-GHz processor and introduces new processors.
High Availability
High availability on the Cisco MCS 7835-H1 is achieved through the following mechanisms:
• Redundant hot-swap 575W power supplies
• Hot-swap SCSI hard drives configured using RAID 1
• Optional DC power supplies for power installations backed up by battery
Serviceability
System Health LEDs
The Cisco MCS 7835-H1 provides system health LEDs and unit identification lights on the front and back of the server to ease identification of system problems. When an internal component fails, this indication is made on an internal component LED (amber) and on the front panel of the appliance. If the item is serviceable without removing the server hood, as in the case of a redundant power supply, the external health LED illuminates. If the item is serviceable by removing the hood, as in the case of a fan failure, the internal health LED illuminates. If no failures have occurred, the system health LEDs are green. If a failure has occurred but a redundant feature has enabled the system to continue running, the LED is amber. If the failure is critical and has caused the system to shut down, the LED is red.
Integrated Lights Out
The Integrated Lights Out (iLO) Standard is included on the motherboard. Combining essential management functions and diagnostics with basic lights-out functions as standard components of the server, iLO is available at no charge. It offers maximum security, availability, and control over business-critical servers without the need to visit the systems physically.
It also provides fundamental server control and monitoring by integrating essential lights-out technology directly into the Cisco MCS 7835-H1 architecture.
Essential lights-out features include remote power control, text-based console, logs, status, and alert forwarding.
The easy-to-use, dedicated lights-out LAN port is accessible through a browser interface. The iLO Standard provides the following additional features:
• It saves a valuable PCI slot for additional functions and reduces installation and setup time.
• It eliminates the need for an external power adapter or any other internal or external cables.
• It provides a rich suite of security features, including Secure Sockets Layer (SSL).
• It provides a scalable solution by allowing group administration of iLO processors.
Redundant ROM
In the Cisco MCS 7835-H1 Unified CallManager Appliance, the ROM is divided into two logical sections. When the system boots, the primary ROM section is executed and used in server operation. During a ROM flash, the backup section is flashed. When the flash is fully completed, the backup section becomes the primary. If under rare conditions the flash does not complete safely, potentially because of power interruption, the backup is available to boot the system. In the situation in which both ROM images are valid, the user can select which image to use at boot time.
DAT Tape Support
The Cisco MCS 7835-H1 appliance 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 7835-H1 appliance.
