# Configuring Fibre Channel Support

Fibre Channel support in OpenStack Compute is remote block storage attached to compute nodes for VMs.

Todo

This below statement needs to be verified for current release

Fibre Channel supported only the KVM hypervisor.

Compute and Block Storage support Fibre Channel automatic zoning on Brocade and Cisco switches. On other hardware Fibre Channel arrays must be pre-zoned or directly attached to the KVM hosts.

## KVM host requirements

You must install these packages on the KVM host:

`sysfsutils`

  Nova uses the `systool` application in this package.

`sg3-utils` or `sg3_utils`

  Nova uses the `sg_scan` and `sginfo` applications.

Installing the `multipath-tools` or `device-mapper-multipath` package is optional.
