The IBM® Private Cloud Offering (PCO) for Microsoft Private Cloud Fast Track configuration is a validated, ready-to-use configuration of servers, networking and storage systems that provide a reliable, scalable, available, high-performance, fault-tolerant management and computing platform for your cloud deployments. Building a complete cloud platform with Microsoft and IBM components A private cloud environment built upon a robust and reliable foundation of IBM System x® servers, IBM XIV® Storage Systems, IBM switches and Microsoft Windows Server 2008 R2 with the Hyper-V hypervisor provides exceptional high availability and fault tolerance for the most demanding virtual environments. To successfully achieve the uptimes demanded by today’s critical business applications and organizations, the private cloud must contain both management and production layers.
