HPE Synergy is a composable infrastructure solution that provides organizations with the flexibility and agility to deploy private clouds. It allows organizations to dynamically compose and recompose their infrastructure resources to meet changing workload demands. HPE Synergy also provides a unified API for infrastructure management, making it easier for organizations to automate and orchestrate infrastructure deployment and management.

RAID 6: RAID 6 provides fault tolerance by using double parity, allowing the system to withstand two simultaneous drive failures. It offers higher fault tolerance compared to RAID 5, which only tolerates a single drive failure. Although RAID 6 has a write performance penalty due to the additional parity calculations, it provides a good balance between capacity and high fault tolerance, which is critical for the customer.

RAID 6 Overview

The HPE ProLiant DL365 Gen11 server is a 1U, single-processor server powered by the AMD EPYC 9004 Series processor with AMD 3D V-Cache technology1. It is designed to deliver high performance, security, and scalability for diverse workloads such as virtualization, cloud computing, data analytics, and AI/ML1. The HPE ProLiant DL365 Gen11 server supports up to 64 cores, 4 TB of memory, 12 NVMe drives, and 8 PCIe Gen4 slots1. It also features the HPE iLO 5 controller, HPE Smart Array controllers, HPE SmartMemory, and HPE Silicon Root of Trust for enhanced management, security, and reliability1.
The HPE ProLiant DL360 Gen11 server is a 1U, dual-processor server powered by the Intel Xeon Scalable processor family2. It is designed to deliver performance, security, and flexibility for diverse workloads such as virtualization, cloud computing, database, and AI/ML2. The HPE ProLiant DL360 Gen11 server supports up to 40 cores, 3.2 TB of memory, 10 NVMe drives, and 6 PCIe Gen4 slots2. It also features the HPE iLO 5 controller, HPE Smart Array controllers, HPE SmartMemory, and HPE Silicon Root of Trust for enhanced management, security, and reliability2.
The HPE ProLiant DL385 Gen11 server is a 2U, dual-processor server powered by the AMD EPYC 9004 Series processor with AMD 3D V-Cache technology3. It is designed to deliver high performance, security, and scalability for diverse workloads such as virtualization, cloud computing, data analytics, and AI/ML3. The HPE ProLiant DL385 Gen11 server supports up to 128 cores, 8 TB of memory, 24 NVMe drives, and 16 PCIe Gen4 slots3. It also features the HPE iLO 5 controller, HPE Smart Array controllers, HPE SmartMemory, and HPE Silicon Root of Trust for enhanced management, security, and reliability3.
The HPE ProLiant DL560 Gen11 server is a 2U, four-processor server powered by the Intel Xeon Platinum processor family4. It is designed to deliver performance, security, and scalability for mission-critical workloads such as database, ERP, CRM, and AI/ML4. The HPE ProLiant DL560 Gen11 server supports up to 112 cores, 12 TB of memory, 12 NVMe drives, and 12 PCIe Gen4 slots4. It also features the HPE iLO 5 controller, HPE Smart Array controllers, HPE SmartMemory with Persistent Memory support (up to 6 TB), and HPE Silicon Root of Trust for enhanced management, security, and reliability4.
Therefore, if the customer has standardized on the AMD platform and asks for a new 1U server, the best option would be the HPE ProLiant DL365 Gen11 server, which offers the highest core count (64), memory capacity (4 TB), and NVMe drive support (12) among the single-processor servers powered by AMD EPYC processors. The other servers either use Intel processors or have a larger form factor (2U).
