ViPR 2.1 - Understanding EMC XtremIO Support in ViPR

Table of Contents

Overview

This article describes the components of EMC XtremIO and the types of provisioning that can be performed by ViPR with the XtremIO block storage.

EMC XtremIO is an all-flash storage array:
  • Comprised of X-Bricks.
  • Each X-Brick consists of Disk Array Enclosures with Solid State Drive (SSD) disks and processors.
  • One or more X-Bricks comprise an XtremIO cluster.
  • Supports both Fibre Channel (FC) and Internet Small Computer System Interface (iSCSI) target storage ports
An EMC XtremIO storage array is added to ViPR as a storage system. You can integrate an XtremIO with ViPR using both the UI and the REST API. When the array is added to ViPR:
  • The XtremIO cluster and storage ports are discovered.
  • ViPR automatically creates one storage pool per cluster.

Once the XtremIO storage array has been discovered by ViPR, a ViPR user, with system administrative privileges, can create a virtual array and virtual pool so that provisioning can be performed using the XtremIO block storage.

These articles provide information on how to add EMC XtremIO to ViPR:

Provisioning Services Available with EMC XtremIO inViPR

Once the XtremIO storage has been added to ViPR, you can provision services using that storage.

The following provisioning services are available with XtremIO block storage :
  • Volumes
    • Create a block volume for a Host, based on the XtremIO virtual pool
    • Expand the size of a created block volume
    • Delete a block volume.
  • Exports
    • Export volumes to hosts (FC and iSCSI)
    • Export volumes to a cluster (FC and iSCSI)
    • Add more volumes to an existing host in a cluster using exclusive mode. The volumes are exposed only to that host.
    • Add host to cluster
    • Remove host from cluster
    • Unexport volumes from cluster (FC and iSCSI)
    • Unexport volumes from host (FC and iSCSI)
  • Snapshots
    • Create a snapshot of a XtremIO volume
    • Delete a snapshot
    • Export a snapshot
    • Unexport a snapshot
