HP Certification Changed HPE0-V27 Questions

OCA (One Config Advanced) and SSET (Solution Sizer and Estimator Tool) are both tools that help design and configure HPE solutions. OCA is a web-based tool that allows users to create and validate configurations for HPE servers, storage, and networking products. SSET is a tool that helps users estimate the power, cooling, and space requirements for HPE solutions. SSET also provides recommendations for rack and power distribution units (PDUs). Compared to OCA, SSET requires an additional datacenter characteristic to configure a solution: the input voltage. This is because the input voltage affects the power consumption and efficiency of the solution. The input voltage can be either single-phase or three-phase, and it can vary depending on the country and region. SSET allows users to select the input voltage from a list of predefined values or enter a custom value. OCA does not require the input voltage as an input parameter, as it only focuses on the product configuration and compatibility. References: Edge to Cloud Solutions: Engineered Experiences to Unlock Your Full Potential, Chapter 5: Next Generation Compute, Storage, and Integrated Data Solutions, page 97.

• Scales up and down to meet workload requirements. = Both
• Can include infrastructure, colocation, power and cooling in a single bill. = HPE GreenLake
• Customer retains ownership of the assets. = Customer
• HPE retains ownership of the assets. = HPE GreenLake
• Customer can add HPE GreenLake Management Service. = HPE GreenLake

• Both: Both customer and HPE GreenLake solutions can scale up and down to meet workload requirements, depending on the type of solution and the contract terms. For example, a customer can purchase a scalable solution, such as HPE Synergy or HPE SimpliVity, and add or remove resources as needed. Alternatively, a customer can use HPE GreenLake, which offers a pay-per-use model, and adjust the capacity and performance on demand.
• HPE GreenLake: HPE GreenLake is a consumption-based model where the customer pays only for the resources they use, on a monthly basis. HPE owns the assets and provides them as a service to the customer, along with the necessary support, management, and optimization. HPE GreenLake can include infrastructure, colocation, power and cooling in a single bill, depending on the customer’s needs and preferences. HPE GreenLake also allows the customer to add HPE GreenLake Management Service, which is a cloud-native platform that provides a unified and consistent experience for managing and optimizing HPE’s edge-to-cloud solutions.
• Customer: Customer is a traditional acquisition model where the customer pays upfront for the hardware, software, and services they need. The customer owns the assets and is responsible for their maintenance, management, and upgrade. This model gives the customer more control, security, and customization over their assets, but it also requires more investment, maintenance, and expertise.
