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™ Agent

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

6“Out-of-band” refers to the path that system management messages travel, which is a different path from the data. “In-band” messages would compete with data for bandwidth.
