Cisco HyperFlex is a hyperconverged infrastructure solution that combines compute, storage, and networking in a software-defined platform. Cisco HyperFlex supports two hypervisors: VMware vSphere and RedHat KVM. VMware vSphere is a widely used virtualization platform that provides enterprise-class features and performance. RedHat KVM is an open source hypervisor that is integrated with the Linux kernel and offers scalability and flexibility. Cisco HyperFlex does not support Microsoft Hyper-V, OpenStack, or Citrix XenServer as hypervisors, although it can interoperate with them through other Cisco products or solutions.
