This topic defines the hardware and software prerequisites that you need to obtain for the metadata server.
Consult your IBM sales representative or product specialist for direction in hardware configuration and ordering.
An LDAP server, which is available and configurable by the SAN File System administrator, is required to provide authentication and authorization. If you do not already have an LDAP server in your environment, install it on a computer in the network that is accessible to the metadata servers and master console. Do not install the LDAP server on the metadata server or master console hardware.
Time synchronization software, such as Network Time Protocol (NTP), ensures that the system clocks on each engine in the metadata-server cluster are synchronized. Having synchronized clocks on each engine will ensure that the log files on each engine accurately reflect the sequence of events in SAN File System.
