How InfoScale™ solutions work in a VMware environment
Using InfoScale™ solutions in a VMware environment means that the InfoScale™ product runs in the operating system, inside the Virtual Machine (VM).
The InfoScale™ component, such as InfoScale, does not run inside the VMware ESXi kernel or in the Hypervisor.
Figure: Architecture overview shows an example of the high-level architecture diagram with InfoScale running in the VM.
Figure: I/O path from Virtual Machine to storage shows the I/O path from the Virtual Machine to the storage.
VMware has several different methods to allocate block storage to a virtual machine:
File-based virtual disks created in VMFS or from NFS - Virtual Disk
Block storage mapped from local disk, Fibre Channel LUNs or iSCSI - Raw Device Mapping
VMware must be configured to use Raw Device Mapping for certain features of Veritas Volume Manager (VxVM) to operate as they do in a physical server environment.
