11. Infortrend s innovated RAID manager RAIDWatch is a Java based program specifically designed for use in managing Infortrend s RAID subsystems RAIDWatch provides a user friendly interface that graphically represents disk array elements and simplifies the normally complicated process of array configuration RAIDWatch also provides real time reporting on the status of the entire array thus making the task of monitoring disk arrays virtually effortless The functionality provided in the Event Monitor sub module in the previous RAIDWatch versions is now integrated into the main management screen and the Configuration Client RAIDWatch complements the on board console interface found on Infortrend s RAID controllers and a line of host based text mode RAID Managers that provide the same functionality but with greater ease of use The following sections describe the outstanding features of RAIDWatch and introduce its conceptual framework 1 1 2 Feature Summary The list below summarizes RAIDWatch features Support RAID level 6 which sustains the highest fault tolerance RAID level migration on a per logical drive basis Each logical drive can be accessed by both controllers 512K 1024K stripe size supported User friendly graphical interface displays multiple information windows for simultaneous managing and monitoring of multiple RAID subsystems Standard TCP IP connections to an Internet agent for full featured worldwide
