— Operating parameters, such as buffer-to-buffer credit
(BB_credit), error detect timeout value (E_D_TOV), resource
allocation timeout value (R_A_TOV), switch priority, switch
speed (1.0625 or 2.1250 Gbps), and preferred Domain_ID.
— Active zoning configuration.
— SNMP configuration parameters, such as trap recipients,
community names, and write authorizations.
• NV-RAM configuration (SAN router) - The NV-RAM
configuration for any managed SAN router is backed up or
restored through customer-supplied TFTP software and the
associated Element Manager application.
Configuration data (stored in NV-RAM on each SAN router)
backed up to the management server is similar to configuration
data backed up for directors and fabric switches. However, the
management server (or any LAN-connected server on which
backup is stored) requires installation of TFTP software. TFTP is a
simple protocol for transferring small files, uses UDP as the
transport protocol, and provides no authentication or encryption
mechanisms.
• SAN management data directory (all products) - Critical
information (for all managed products) stored in this directory is
automatically backed up to a removable CD-RW when the server
is rebooted or when directory contents change. The SAN
management data directory includes:
— All log files (SAN management logs and individual director
or switch Element Manager logs).
— All configuration data (product definitions, user names,
passwords, user rights, nicknames, session options, SNMP
trap recipients, e-mail recipients, and Ethernet event
notifications).
— Zoning library (all zone sets and zone definitions).
— Firmware library.
— Call-home settings (phone numbers and dialing options).
— Configuration data for each managed product (stored on the
management server and in NV-RAM on each product).
