In the HPE architectural process, a " physical " site survey is distinct from a " logical " or " technical " assessment. While a technical assessment focuses on software versions and network configurations, the physical survey evaluates the actual data center environment where the hardware will reside. Gathering information on physical access controls is essential for security compliance, ensuring that the site meets the requirements for restricted access, biometric verification, or logged entry as dictated by the customer ' s security policy. Similarly, assessing environmental controls is critical to ensure the solution ' s longevity and stability. This includes verifying the heating, ventilation, and air conditioning (HVAC) capacity to handle the BTU output of the new equipment, as well as fire suppression systems and humidity controls. Information like VLANs, patch levels, and disk capacity are gathered during the logical discovery phase or via automated tools like SAF Collector, as they do not require a physical inspection of the facility. Ensuring the physical site is ready is a prerequisite for a successful deployment of HPE GreenLake or ProLiant infrastructure. References:

Spreading the infrastructure across additional racks can help reduce the power density per rack and avoid exceeding the 5kW limit of the customer's data center. This option may require more space and cabling, but it can preserve the performance and availability of the planned solution. Hosting the compute solution with a colocation provider can also help overcome the power constraint of the customer's data center, as well as provide other benefits such as scalability, security, and connectivity. This option may incur additional costs and complexity, but it can also enable the customer to access cloud services and hybrid solutions more easily.
Both options are compatible with HPE GreenLake pay-per-use model, which can help the customer optimize their IT spending and consumption. References: https://www.hpe.com/psnow/doc/a00107143enw
