Configuration Planning Tasks
182 SAN High Availability Planning Guide
Task 5: Plan Ethernet Access
Directors and the HAFM appliance can be ordered in an HP-supplied equipment
rack in accordance with customer specifications; however, you may need to:
■ Connect equipment racks — Customer-supplied Ethernet hubs in multiple
equipment racks can be connected to provide HAFM appliance access to up to
48 managed HP products. Racks can be placed at any distance up to the limit
of the 10/100 megabit per second (Mbps) LAN segment.
■ Consolidate HAFM appliance operation — If HAFM appliance operation
is to be consolidated to one primary server and one or more backup servers,
plan for Ethernet cabling to interconnect equipment racks and ensure that all
directors, switches, and server platforms have unique IP addresses.
■ Install equipment racks on a public LAN — If a public LAN segment is to
be used, determine from the customer’s network administrator how to
integrate the products and HAFM appliance. Ensure all access, security, and
IP addressing issues are resolved.
Note: HP recommends that directors, switches, and the HAFM appliance be installed
in a secure physical network domain to optimize security and avoid traffic problems.
■ Install remote user workstations — Plan for access to the LAN segment
containing the HAFM appliance if remote user workstations are required.
