Base Configuration

BlackBerry Enterprise Server can be configured in two basic ways:

• All in One Configuration -- Both BES and database (MSDE or SQL) are running on the same machine (Master server). In an All in One Configuration, you need:
  • 1 Exchange Server
  • 2 Windows Servers (Master and Replica)
  • 1 Domain Controller
• Distributed Configuration -- BES and SQL are running on different machines (two Master servers). In a Distributed Configuration, you need:
  • 1 Exchange Server
  • 2 Windows Servers (Master and Replica)
  • 1 SQL Server (If desired, this machine can be protected separately in a back-end SQL scenario. See the Arcserve RHA SQL Operation Guide for more information.)
  • 1 Domain Controller

Install the Arcserve RHA Engine on all servers participating in HA scenarios.

The following conditions also apply:

• The two Windows servers should be running Windows Server 2003, or 2008 with the same level of service packs and hot fixes installed.
• All IP addresses are statically assigned (DHCP-assigned IP addresses on the Master or Replica server are not supported).
• The server to be protected is not a domain controller or DNS server.
• The Exchange System Manager is installed on both Windows Servers prior to installing Arcserve RHA.

For SQL 2005 or MSDE in Same Machine Configuration:

• Ensure you have installed a SQL instance on both servers (Master and Replica).
• Ensure both servers have the same SQL version, service packs and hot fixes installed.
• Ensure both servers hold identical SQL Server instances, such as "default" or "named".
• Ensure both servers reside in the same Active Directory forest and are members of the same domain or trusted domains.
• Ensure the drive letters containing database files are identical on both servers.
• Ensure the full path to the default system database of each instance is identical on both servers.
• Verify that the port defined in the Network Configuration TCP/IP properties of the SQL instance(s) is assigned statically and is identical on both servers.

Important! Install BES ONLY on the production server prior to installing Arcserve RHA. If you have already installed BES on the server you intend to use as the Replica, uninstall BES before proceeding.
