Rack and Server Specifications
All In-Tuition racks and server equipment are specified for maximum redundancy based on experience gained from many years of running highly reliable systems:
A and B power circuits. Power feeds come from different Power Distribution Units (PDU) for redundancy - if one power circuit should fail, the other circuit is available. Power interruptions are most often as a result of servers’ power supplies failing. This can cause a power spike, which then activates the trip switch on the PDU.
Servers and Network Switches have two power supplies, one plugged into the A power circuit, the other plugged into the B circuit. If a circuit should fail, the other power supply is already on-line therefore continuity of power supply is maintained with zero downtime.
Racks and Servers have remote controlled power cycling facilities so that engineers can easily power cycle equipment.
Servers are connected to at least two core network switches and each connection is at least one 1Gb.
