FC Storage

ZStack supports FC storage passthroughs, automatically scans and discovers FC storages that you preconfigured, and provides a direct display of FC storage details. Specifically, FC LUN devices that can be correctly detected support the following usages:
  • LUN devices of a FC storage can be passed through to VM instances.
  • LUN devices of a FC storage can be added as Shared Block primary storages in shared block.

In the navigation pane of the ZStack Private Cloud UI, choose Hardware > SAN Storage. On the SAN Storage page, click FC Storage. Then, the FC Storage tab page is displayed, as shown in FC Storage Page.

FC Storage Operations

You can perform the following operations on an FC storage:
  • Sync device information: Refresh manually the FC storage list to detect the latest FC storage list.
  • Attach VM Instance: Pass through directly an LUN device of the FC storage to VM instances. An LUN device can attach multiple VM instances, while a VM instance can be attached to multiple LUN devices.
  • Detach VM Instance: Detach the attached VM instances from an LUN device.
  • Check cluster status: Check the status of the cluster where the LUN device is running. If all hosts normally connect to the LUN device, this LUN device can be added as a Shared Block primary storage.

Notice

ZStack not only allows you to add an FC LUN device as a Shared Block primary storage, but also allows you to directly pass through an FC LUN device to VM instances. When you use the FC LUN device, note that:
  • If the status of a cluster to which an FC LUN device is attached is normal, and VM instances are not attached to the FC LUN device, the FC LUN device can be added as a Shared Block primary storage.
  • An LUN device that is not added as a primary storage can attach VM instances.
  • An LUN device can attach multiple VM instances, while a VM instance can be attached to multiple LUN devices.
