2. SNMP Support Ensures Compliance with All Major
Systems-management Platforms
The Resource Manager software package supports Simple Network
Management Protocol (SNMP). SNMP is the most widely used network-
management protocol in the marketplace. System Information Messages (SIMs)
are converted to SNMP Management Information Blocks (MIBs) for use with the
Resource Manager software package, or the VERITAS

4. Host Storage Domains
The Lightning 9900 V Series and Thunder 9500 V Series systems provide for
“virtual” Fibre Channel ports that are logically managed by intelligent Fibre
Channel controller cards. Each physical Fibre Channel port has multiple Host
Storage Domains or HSDs. An HSD supports a “logical” Fibre Channel port (see
Figure 27) each with its own set of logical units (LUNs). Hosts are matched to
their assigned HSD based on a unique World Wide Names (WWNs) identifier.

5. Hitachi LUN Manager and LUN Expansion Manager Software Simplifies
Configuration Management and Reduces Staffing Costs
Hitachi LUN Manager software is an open systems management utility. With
LUN Manager software, open systems LUNs can be defined, configured, and
maintained. There is no more waiting for the hardware vendor to come and make
configuration changes. LUN Manager software includes an easy-to-use, GUI-based
interface that allows the definition of paths for LUNs, the reconfiguration of
LUN-to-port assignments, or the viewing of the Hitachi Freedom Storage remote
service information messages. Because LUN Manager software can assign multiple
paths to a single LUN, support of alternate path failover, path load balancing, and
clustered systems is possible. Running on a standard Windows-based PC
connected to the storage systems by a dedicated LAN, LUN Manager software can
support multiple systems.
