The ability to create global namespace, high availability, and volume economics enables unique capabilities when Red Hat Storage Server is used on Amazon Web Services (AWS). In this session, you’ll learn about the capabilities and the potential of using AWS ephemeral storage, availability zones, and regions to deliver a truly distributed cloud storage solution that is geographically diverse, cost effective, and highly available.

2. GlusterFS Community Project
l Community driven Open Source @gluster.org
l Distributed file system on top of local file system
l No metadata server with elastic hashing algorithm
l Spreads files across local file system directories called bricks
l Stores metadata in extended attributes of local file system
l Modular stackable architecture based on user-space FUSE

3. What is Red Hat Storage
l Open, Software Defined Storage Solution for On-Premise,
Virtualized and Cloud environments
l Enterprise implementation of GlusterFS technology
l RHEL + XFS + GlusterFS
l Support Subscription
l 24x7 Premium Support

4. RED HAT STORAGE CONCEPTS
VOLUME
A namespace presented as a
POSIX mount point and is
comprised of bricks.
BRICK
The basic unit of storage,
represented by an export
directory on
a server
SERVER/NODES
Contain the bricks

5. Elastic Hash Algorithm
• No central metadata
• No Performance Bottleneck
• Eliminates risk scenarios
• Location hashed intelligently on filename
• Unique identifiers, similar to md5sum
• The “Elastic” Part
• Files assigned to virtual volumes
• Virtual volumes assigned to multiple bricks

7. Why run RHS on AWS?
You need shared access to a file system
GlusterFS, NFS and CIFS
You need a really large file system
I’ve created multiple 2PB clusters

8. Things to think about -
Run at least replica 2 in two availability zone
Single AZ = no durability commitments
Dual AZ = 99.95% available
Durability
Backing store
Performance
Network interface
EBS interface
EBS performance

9. Backing stores
EBS
between 0.1% – 0.5% AFR per volume
Ephemeral
hs1.8xlarge
48 terabytes of storage across 24 hard disk drives
i2.8xlarge
~5.7 terabytes of storage across 8 SSDs

10. Running RHS on EC2
Use Reserved Instances!
RHS is a perfect use case for reserved instances.
Discounts of up to 65%
Purely a billing construct, no technical implications.
m3.xlarge is perfect for RHS @ $.25/hr (1yr heavy RI)

11. VOLUME CONFIGURATION
l Global namespace
l Bricks are XFS
filesystems
l Volumes are made of
bricks
l Distributed
l Replicated
l Distributed and
replicated
l Geo-replication
