Motivation
Motivation
• Challenges:
High complexity configuration
Hardware maintenance
Software changes
• Several systems proposed to reduce management complexity
AutoPilot (Microsoft), SmartFrog (HP), OpenView (HP), etc.
• Several problems remain unsolved thus keeping the complexity and the cost of running a DC high.
Goal
• Address three important problems:
Automatically determine the physical location of servers.
Notify administrators of any location changes.
Determine status of servers even if network is down.
• Our solution to these problems relies on :
Auto-configuring wireless sensor network.
Distributed monitoring and management system.
Wireless technology used
• Zigbee IEEE 802.15.4:
Up to 65536 Personal area networks with 16 channels each.
Specific roles of each device ( coordinator, slave).
• Two types of messages:
Transparent mode (broadcast only, simple).
API communication mode (unicast, reliable, RSSI).
