The model of the UPBA2 board is
CN21UPBA2.

• Service processing capabilities

  
  

  • Two Intel^? Xeon^? quad-core processors
    with low power consumption

    
    

  • Each quad-core processor supports 12 MB level-2 cache.

    
    

  • The processors support 1333 MHz Front Side Bus (FSB) and provide
    a transmission rate of 10.66 Gbyte/s.

    
    

  • The processors support a maximum of 24 GB memory.

    
    

  • The VLP DDR2 RDIMMs support Error Checking and Correcting (ECC)
    and a working frequency of up to 667 MHz or lower than 533 MHz.

• Interfaces (the USB and BMC are external interfaces; others
  are used for internal communication)

  
  

  • Two Base interfaces (10/100/1000M BASE-T Ethernet interfaces)

    
    

  • Two Fabric interfaces (1000M BASE-BX Ethernet interfaces)

    
    

  • One Update interface (1000M BASE-BX Ethernet interface)

    
    

  • One on-board USB interface (J34), which connects to a USB Flash
    module of up to 4 GB

    
    

  • One BMC serial port (also serving as the system serial port),
    which complies with RS232 specifications and uses the RJ45 connector

    
    

  • Two SAS hard disk interfaces on the front panel for configuring
    two 2.5-inch hard disks with SAS interfaces

    
    

  • Two USB 2.0 interfaces (compatible with the USB 1.1 specifications)
    on the front panel

  
  

• Management functions

  The UPBA provides a BMC module with
  independent power supply. The BMC module connects to the SMU through
  the IPMB bus with redundancy configuration.

  The BMC module performs
  the following functions:

  • Managing the information about the Field Replaceable Unit (FRU),
    Sensor Data Record (SDR), and System Event Log (SEL)

  • Monitoring the temperature and voltage and reporting alarms

  • Controlling the hot-swap, power-on, power-off, and reset of
    the board

  • Supporting console redirection to implement remote management
    through networks

  • Supporting Serial over LAN (SOL) to implement remote management
    through networks

  • Supporting remote KVM over IP

• Integration capabilities

  • Dual-channel gigabit Ethernet controller

  • Intelligent Platform Management Interface (IPMI)

  • SAS storage controller

  • Video controller

  
  
• Supporting hot swapping
