the operating system as a single, large LUN. This capability simplifies storage management because there are fewer LUNs to manage. Two levels of password protection, user and administrator, ensure maximum data security. Users can view only Hitachi Freedom Storage LUN configuration information, while administrators can access all LUN configuration information and functions. Administrators can customize access privileges for individual users, thus providing maximum flexibility and control of these powerful management capabilities.
6. Hitachi SANtinel Software
SANtinel software controls host access to Hitachi Freedom Storage systems LUNs in open systems, multiplatform, or SAN environments. This enables users to restrict server access to only those LUNs for which they are authorized, as shown in Figure 28.
SANtinel software for open systems, running on the Hitachi Freedom Storage systems, allows administrators to define multiple HSDs for each physical Fibre Channel port on the system. An HSD consists of a virtual (logical) Fibre Channel port and an associated set of LUNs visible only via that logical Fibre Channel port.
Connections from host servers arriving at the physical Fibre Channel port are routed to the logical Fiber Channel port within the appropriate HSD based upon the Fibre Channel WWN of the host.
The storage administrator creates the HSD, sets the host mode of the logical Fibre Channel port within that HSD, and maps the LUNs to appear within that HSD. Then the storage administrator authorizes a particular host to "see" an HSD on that physical port by assigning the Fibre Channel WWN of that host to the HSD in question.
Because the WWN is used to route connections to the appropriate HSD, the
