  • There is a limit on the total provisioned IOPS per volume and the limit is 40,000. Hence, while adding 24 PIOPS SSD disks, you must ensure that the total IOPS of all disks does not exceed 40,000.
  • Creation of Red Hat Gluster Storage volume snapshot is supported on magnetic, general purpose SSD and PIOPS EBS volumes. You can also browse the snapshot content using USS. See chapter Managing Snapshots in the Red Hat Gluster Storage Administration Guide for information on managing Red Hat Gluster Storage volume snapshots.
  • Tiering feature of Red Hat Gluster Storage is supported in the Amazon Web Service environment. You can attach bricks created out of PIOPS or general purpose SSD volumes as hot tier to an existing or new Red Hat Gluster Storage volume created out of magnetic EBS volumes. See chapter Managing Tiering in the Red Hat Gluster Storage Administration Guide for information on creation of tiered volumes.
