There can be several other risks about the locations designed for the data center, where racks may not be present at all or may not be designed for the chosen type of servers, or the uninterruptible power supply may be outdated or may not have enough power for the entire environment. Existing switches may lack in redundancy or performance (may be they have just 1 Gbps ports). Environmental conditions must be verified to validate that cooling and HVAC systems are sized well.
