Consider repairability, remaining support and actual operating demand. Extending service life is useful only when the equipment still meets your security and reliability requirements.
Use measured average input power for the same workload. PSU ratings and processor TDP are different from total system power.
Energy difference = (current W − proposed W) × hours × units ÷ 1,000. Excludes cooling, embodied emissions and purchase costs.CONNECTION DETAILS
Check the protocol and port requirements of the equipment you intend to connect. Ethernet, Fibre Channel, InfiniBand and carrier interfaces are not interchangeable.
Browse the categories above for related equipment, then send us the full configuration so we can check the fit.
