systems, and the user’s intranet (public LAN), which allows users to access the
Resource Manager software package.
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
® Storage Manager ™ , IBM
Tivoli ® , CA ™ Unicenter ® or HP ® OpenView ® . With CA Unicenter, “super MIBs”
allows the control of the Lightning 9900 V Series or Thunder 9500 V Series
systems using CA Unicenter commands. This out-of-band

reporting format
ensures that Resource Manager software can determine the status of your Hitachi
Freedom Storage system even if the data channel path is down.
3. Java ™ A g e n t
The Hitachi Web Utility runs on Web browsers, such as Internet Explorer ®
and Netscape ® Navigator ® . These programs run under the Microsoft ® Windows
and Sun ™ Solaris ™ operating systems and provide a user-friendly interface for the
Lightning 9900 V Series and Thunder 9500 V Series systems Remote Console –
Storage Navigator functions, which are all based on the use of Java agents.
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.
LUN security is provided by Hitachi SANtinel
™ software, which fences access to
LUNs based upon host WWNs. Under this innovative software structure, one
LUN is reserved for the command and control device.
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.
Hitachi LUN Expansion Manager software features logical unit size expansion
that dramatically improves LUN flexibility. Multiple LUNs can be presented to
