Centralized and Open Systems Management Software Simplifies IT Operations

information at the touch of a button. The robust GUI-oriented command screen for Hitachi Graph-Track™is shown in Figure 26. Running on a PC attached to a dedicated LAN, Hitachi Graph-Track™displays real-time or historical data for all connected Lightning 9900™ systems, helping users identify important peaks in utilization and ongoing trends in processing. With Hitachi Graph-Track™, users can analyze discrete storage activities and determine the precise impact of each activity on system operation. It scrutinizes activity all the way to the logical device level, reporting on channel interface processor usage rates, cache usage rate by function, and logical device utilization. This data pinpoints specific activities that may have a negative impact on operations and lets the user fine-tune the system so that it can be used to maximum advantage.

Hitachi Graph-Track™also highlights valuable cache information. Cache read/write and read-hit ratios are reported in real time. Each system connected to Hitachi Graph-Track™can be tuned separately.

Hitachi LUN Manager simplifies configuration management and reduces staffing costs

Hitachi LUN Manager is an open systems management utility. With Hitachi LUN Manager, open systems Logical Units (LUNs) can be defined, configured, and maintained. There is no more waiting for the hardware vendor to come and make configuration changes. Hitachi LUN Manager includes an easy-to-use, GUI-based interface that allows the easy definition of paths for LUNs, the reconfiguration of LUN-to-port assignments, or the viewing of the Lightning 9900™ remote service information messages. Because the Hitachi LUN Manager 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 subsystems by a dedicated LAN, Hitachi LUN Manager can support up to eight Lightning 9900 systems.
