Chapter 2. Accessing Red Hat Gluster Storage using Amazon Web Services
Red Hat Gluster Storage for Public Cloud packages glusterFS as an Amazon Machine Image (AMI) for deploying scalable network attached storage (NAS) in the Amazon Web Services (AWS) public cloud. This powerful storage server provides a highly available, scalable, virtualized, and centrally managed pool of storage for Amazon users. Red Hat Gluster Storage for Public Cloud provides highly available storage within AWS. Synchronous n-way replication across AWS Availability Zones provides high availability within an AWS Region. Asynchronous geo-replication provides continuous data replication to ensure high availability across AWS regions. The glusterFS global namespace capability aggregates disk and memory resources into a unified storage volume that is abstracted from the physical hardware.
The following diagram illustrates Amazon Web Services integration with Red Hat Gluster Storage:
Figure 2.1. Amazon Web Services integration Architecture
The following features of Red Hat Gluster Storage Server is not supported on Amazon Web Services:
- Red Hat Gluster Storage Console and Nagios Monitoring
- NFS and CIFS High Availability
For information on obtaining access to AMI, see https://access.redhat.com/knowledge/articles/145693.
2.1. Launching Red Hat Gluster Storage Instances
This section describes how to launch Red Hat Gluster Storage instances on Amazon Web Services.
The supported configuration for two-way and three-way replication is up to 24 Amazon EBS volumes of equal size.
Table 2.1. Supported Configuration on Amazon Web Services
|EBS Volume Type||Minimum Number of Volumes per Instance||Maximum Number of Volumes per Instance||EBS Volume Capacity Range|
|Magnetic||1||24||1 GiB - 1 TiB|
|General purpose SSD||1||24||1 GiB - 16 TiB|
|PIOPS SSD||1||24||4 GiB - 16 TiB|
|Optimized HDD (ST1)||1||24||500 GiB – 16 TiB|
|Cold HDD (SC1)||1||24||500 GiB – 16 TiB|
- 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.
