SuperTrak66™ User's Manual | Chapter 4 |
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 I2O 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)I2O 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.
