performed at cache speeds, with no disk latency delay. With FlashAccess software,
a portion of cache memory can be allocated to specific data. Users can add, delete,
or change FlashAccess software managed data at any time, quickly and easily.
Defined by the LUN for open systems, cache data can be as small as a single
track or as large as an entire volume. For increased configuration flexibility,
FlashAccess software offers multiple modes of operation.
9. Remote Console – Storage Navigator
The Lightning 9900 V Series Remote Console – Storage Navigator is
provided as a Sun Java
®
-applet program, which can execute on any machine that
supports a Java Virtual Machine (JVM). The Remote Console – Storage Navigator
PC hosts the Remote Console – Storage Navigator Java-applet program and is
attached to the Lightning 9900 V Series system(s) via a TCP/IP local-area network
(LAN). When a Remote Console – Storage Navigator accesses and logs into the
desired service processor (SVP), the Remote Console applet is downloaded from
the SVP to the Remote and runs on the Web browser of the Remote Console PC.
In this way, the Remote Console communicates with the attached Lightning 9900
V Series systems via a TCP/IP network.
Two LANs can be attached to the Lightning 9900 V Series and Thunder
9500 V Series systems: an internal LAN (private LAN), which is used to connect
the SVPs of multiple systems, and the user’s intranet (public LAN), which allows
you to access the Remote Console – Storage Navigator functions from individual
Remote Console – Storage Navigator PCs. The Remote Console – Storage
Navigator communicates directly with the SVP of each attached system to obtain
system configuration and status information and send user-requested commands
to the system. The Lightning 9900 V Series systems’ Remote Console – Storage
Navigator Java-applet program is downloaded to the Remote Console – Storage
Navigator (Web client) from the SVP (Web server) each time the Remote Console
– Storage Navigator is connected to the SVP. The Remote Console – Storage
Navigator Java-applet program runs on Web browsers, such as Internet Explorer
®
and Netscape
®
Navigator
®
, which run under the Microsoft
®
Windows NT
®
,
Windows
®
2000, and Sun
™
Solaris
™
operating systems to provide a user-friendly
interface for the Lightning 9900 V Series Remote Console – Storage Navigator
functions.

and reporting programs.
Graph-Track software gives users a more reliable and centralized way to
manage performance. Available for S/390, UNIX, Windows NT, and
Windows 2000 environments, this unique tool monitors hardware performance
and supplies complete system-storage information at the touch of a button. The
robust GUI-oriented command screen for Graph-Track is shown in Figure 29.
Running on a PC attached to a dedicated LAN, Graph-Track software displays
real-time or historical data for all connected Lightning 9900 V Series systems,
helping users identify important peaks in utilization and ongoing trends in
processing. With Graph-Track software, users can analyze discrete storage activities
and determine the precise impact of each activity on system operations. It
