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.
