6.1  Step 1:  Choose a Configuration and Determine
       Hardware Requirements

  Quick Summary of an AlphaServer 8200 Galaxy Configuration

  Only one possible configuration.

  *   Two instances only

  *   5 slots for:

      *   Two CPU modules (two CPUs each)

      *   Two I/O modules

      *   One memory module

  6.1.1  Using the OpenVMS Galculator
  The OpenVMS Galculator is an application program you can
  use to determine the Galaxy configuration that best suits your
  needs.  It is available at:
  http://www.openvms.digital.com

  To create an OpenVMS Galaxy Version 7.2 computing envi-
  ronment on an AlphaServer 8200, the Galculator steps you
  through the following hardware requirements:

  *   One I/O module (I/O module of type KFTIA or KFTHA)

      for each partition

  *   At least one CPU module for each partition

  *   A dedicated serial console port for each partition

      The AlphaServer 8200 provides a built-in UART for
      the first console line.  Each additional console requires a
      module set.

      The only hardware required for Galaxy operation that is
      not in the typical AlphaServer 8200 configuration is the
      KFE72-DA console subsystem.

      The KFE72-DA module set is the set of EISA-bus mod-
      ules that establish the console port.

  *   A display device for the OpenVMS Galaxy Configuration

      Utility.
      Compaq recommends an Alpha or VAX workstation run-
      ning DECwindows or a Windows NT workstation with
      an Xterminal emulator.  For more information about the
      OpenVMS Galaxy Configuration Utility, see      Chapter 9.

  OpenVMS V7.2 customers might want to use the following
  optional hardware:

  *   Plug in units (PIU) for I/O expansion from an I/O module
      (PCI or XMI)

  *   I/O adapters for network, storage, or traditional cluster
      interconnects

  *   Additional CPUs

   2-instance  AlphaServer  8200  Galaxy  Parts  List
   ______________________________________________________________________
   REQUIRED  HARDWARE:

   Notes:
   1)  The  following  parts  list  should  be  compared  against  the  base  system
      parts  list  to  determine  if  the  parts  already  exist,  or  need  to  be
      ordered.
   2)  This  parts  list  covers  only  the  parts  required  to  transform  an
      existing  system  into  a  Galaxy  configuration.   Although  we  have  tried
      to  be  complete,  there  is  no  substitute  for  the  official  options  catalog.

   CONSOLE  SUBSYSTEMS  and  PCI  CARD-CAGES

   1  KFE72-DA  Console  Subsystems  (3  module  set).
   1  DWLPB-AA/BA  PCI/EISA  card-cages.

   Notes:
   1)  Use  DWLPB-AA  (dual  PCI  card-cage,  back-side)  for  PCI/EISA  options.
   2)  Use  DWLPB-BA  (single  PCI  card-cage,  front  or  back)  for  PCI  expansion.
   3)  Each  KFE72-DA  contains  1  on-board  Ethernet  port,  2  serial  line  ports,
      and  1  floppy  disk  port.
   4)  The  KFE72-DA  module  set  must  be  placed  in  the  bottom-most  card-cage  slots.
   I/O  PROCESSOR  MODULES

   1  KFTHA-AA  4-Hose  I/O  Processor  Modules.
   1  KFTIA-AA  1-Hose  IO  Processor  Modules.

   Notes:
   1)  If  you  use  both  KFTIA  and  KFTHA  modules,  a  KFTIA  must  be  placed  in
      slot  9.  The  remaining  I/O  modules  can  be  placed  in  any  order  as  long  as  you
      configure  consecutive  slots  in  descending  order  (slots  9,8,7,6).
   2)  If  you  intend  to  use  an  XMI  subsystem,  it  must  be  cabled  into  a  KFTIA
      in  system  slot  9.
   PROCESSOR  MODULES

   5  756P1-AX  Processor  Modules.
   Notes:
   1)  A  number  of  different  speed  processors  available  are  available.
      The  756P1-AX  is  a  dual  440mhz  module.   You  can  use  whichever  speed
      processors  you  choose  as  long  as  all  processors  are  the  same  speed.
   2)  After  installing  the  processors,  be  sure  to  upgrade  to  the  proper
      Galaxy  Console  Firmware.  (LFU>  Update  KN7C*).

   MISCELLANEOUS  PARTS
   In  addition  to  the  above  parts,  consider  the  following  parts  to  help  you
   organize  and  manage  your  Galaxy  system.

   1)  A  Terminal-Server  (for  example,  DECserver200  or  900,  etc.)  to  organize
      your  console  serial  lines.  Having  reverse-LAT  access  to  your  consoles  is
      helpful.
   2)  An  Ethernet  HUB  to  manage  your  Ethernet  connections.
   3)  A  suitable  workstation  for  using  the  OpenVMS  Galaxy  Configuration  Utility.
   4)  Refer  to  the  OpenVMS  Galaxy  Guide  for  more  information.

    MEMORY  MODULES
   1  MS7CC-EA  (1GB)  Memory  Modules.

   1  MS7CC-GA  (4GB)  Memory  Modules.
   SYSTEM  CAPACITY  AS  SPECIFIED:

   1)  There  are  10  processors  of  which  8  can  be  migrated.
   2)  There  are  5  I/O  Hoses  available  for  PCI  and  XMI.
   3)  There  are  57  possible  PCI  devices  if  all  hoses  are  used.

   4)  There  are  2  KFTIA  I/O  module.
      Each  contains  2  Ethernet  Ports,  4  SCSI  Ports,  and  1  optional  FDDI  port.
      Remember  that  only  the  instance  owning  the  I/O  module
      can  access  these  ports.
