A typical installation of the SuperCheck software components on a network might
look like Figure 17 on page 32. The major elements of this network are (from top to
bottom):
−
Remote Monitoring Stations (via Internet)
−
Main Network File Server (with direct Internet access via a Firewall)
−
Internal SuperTrak stations (connected via Intranet/LAN)
−
Internal Monitoring Station
As shown, different components of SuperCheck are installed on each of the
network elements.
(1) SuperCheck Utility - The SuperCheck Monitoring Utility (the GUI that you will
be using) may be installed on any system element with a TCP/IP connection
where you want to perform monitoring. As shown in Figure 17, the SuperCheck
utility is installed on the main File Server, on both SuperTrak66 stations, on
two remote systems over the Internet, and on one internal system. NOTE: For
security reasons, array maintenance features can only be performed at the
actual server location of a SuperTrak66 array and are unavailable at all other
consoles.
(2) Message Server - The Message Server software component serves as the
main link between all SuperTrak arrays residing on the network, the internal
Intranet/LAN (via TCP/IP protocols), and remote monitoring stations
communicating via the Internet. For remote Internet monitoring, the Message
Server component must be installed on a machine with an unique IP address
that is visible to the Internet (as in our example). From its cent ral
communications position, the Message Server software interfaces with all
SuperTrak arrays located on the LAN and allows all system elements (with the
GUI installed) to see those arrays. The File Server where the Message Server
software is installed may or may not house a SuperTrak array. In our example
on Figure 17, it does not. One reason may be that the File Server is not
running Windows NT 4.0.
(3) Message Agent - The Message Agent software component must be installed
on each file server that will house a SuperTrak array. The Message Agent
communicates with both the Message Server and the SuperTrak66 controller.
Installing the Message Agent automatically installs the I
2
O device driver. NOTE:
All stations containing SuperTrak66 must be running Windows NT 4.0.
Maintenance on SuperTrak arrays can be performed only using these stations .
(4) I
2
O Device Driver – Installed automatically with the Message Agent, the driver
allows the station to communicate directly between the Promise SuperTrak
controller card and Windows NT. This permits Windows NT to recognize RAID
arrays attached to it.
