Implementing Windows Server 2019 Storage Spaces Direct using HPE ProLiant servers

1.0 Introduction

This document discusses Azure Stack HCI solution implementation using HPE ProLiant Gen9 and Gen10 servers. Windows Server 2019 Storage Spaces Direct (S2D) is a software-defined storage feature based on Storage Spaces technology. It uses internal storage devices such as SATA and SAS HDDs, SSDs, and NVMe disks to create shared disk volumes. Distributed among several cluster nodes, these volumes can withstand disk, node, and network failures, and continue to operate normally without downtime. Different levels of resiliency can be achieved using mirror, parity, or a combination of the two. S2D is mainly targeted at cloud applications, Hyper-V, storage for backup and replication, and hyperconverged/converged infrastructures.

2.0 HPE Azure Stack HCI solutions

HPE Azure Stack HCI solutions are configured to deliver solid performance, improved reliability, and high availability. They can be implemented as 2 to 16 node configurations, providing you with the ability to deploy an engineered, tested, and validated private cloud environment to meet your most demanding workloads. All HPE Azure Stack HCI solutions are available as hyperconverged or converged solutions.

2.1 HPE hybrid

HPE hybrid solutions start with two nodes of HPE ProLiant servers using RDMA-capable network adapters to provide high performance with minimum processor utilization. In order to make use of HPE solutions using RDMA networking, an RDMA compatible networking infrastructure is required. HPE hybrid solutions combine different types of drives (HDD/SSD/NVMe) to allow read/write caching and are available in both LFF and SFF form factors.
