HP IO Accelerator Driver 3.1.1 Release Notes

System requirements 9
• VMware ESXi 5.0
IO Accelerator devices are only compatible with operating systems that are 64-bit x86 architecture. This
requirement means the following scenarios are supported:
• Using the IO Accelerator device as a VMFS datastore within the hypervisor and then sharing that
storage with guest operating systems. Guest operating systems can be 32-bit or 64-bit because they are
not directly using the IO Accelerator device.
• Using VMDirectPathIO to allow a VM to directly use the IO Accelerator device. In this case, only
supported operating systems can use the device. VMDirectPathIO is currently supported on Windows
and Linux operating systems that are supported on HP IO Accelerator devices.
The VSL software is only required for ESX or ESXi if you plan to use the IO Accelerator device as a VMFS
datastore. If you are passing the devices through using VMDirectPathIO, you do not need to install the
VSL on your the ESX or ESXi system. Instead, install the VSL on the guest system. For example, pass the
device through to a Windows VM, and then install the Windows VSL on that VM.
For installation instructions, see the HP IO Accelerator for Linux User Guide or the HP IO Accelerator for
Windows User Guide.
