Storage Transforming to Reflect Compute

Storage must support the public and private cloud environment• Storage is the Achilles heel of full data center virtualization

• Storage performance, availability, capacity, & interface is the Achilles heel of public cloud

• Big Data, data migration, multi-site consistency are the Achilles heel of hybrid cloud

Storage will look like the computing environment• Storage should be a commoditized, virtualized, centrally managed pool

• Monolithic proprietary systems now challenged by nimble and shared network storage

• Storage becomes a software problem

• The “Google model” of storage

Gluster Architecture Advantages

Software onlyNo metadata server• Fully distributed architecture, no bottleneck• Gluster Elastic Hash

High performance global namespace• Scale out with linear performance• Hundreds of petabytes• 1 GbE, 10GbE

High availability• Replication to survive hardware failure• Self-healing• Data stored in NFS-like native format

Stackable userspace design• No kernel dependencies, simple install• Match specific workload profiles• Early maturity and rich functionality

‘Google Storage’ for

Everyone

• Intelligence in the SW

•Leverage commodity HW

•Scale-out elastically

•Replication for reliability

•Software enables virtualization

GlusterFS & OpenStack

VM Image Storage – Answer to VMWare VMFS

Unified File & Object Storage – Application Data

GeoReplication – Enable Hybrid Clouds


Problem• Capacity growth from 144TB to 1+PB• Multiple distributed users/departments• Multi OS access - Windows, Linux and Unix

Solution• GlusterFS Cluster• Solaris/ZFS/x4500 w/ InfiniBand• Native CIFS/ NFS access

Benefits• Capacity on demand / pay as you grow• Centralized management• Higher reliability• OPEX decreased by 10X

Partners Healthcare

• Over 500 TB

• 9 Sun “Thumper” systems in cluster

Private Cloud: Centralized Storage as a Service


Pandora Internet Radio

Problem• Explosive user & title growth• As many as 12 file formats for each song• ‘Hot’ content and long tail

Solution• Three data centers, each with a six-node

GlusterFS cluster• Replication for high availability• 250+ TB total capacity

Benefits• Easily scale capacity• Centralized management; one

administrator to manage day-to-day operations

• No changes to application• Higher reliability

• 1.2 PB of audio served per week

• 13 million files

• Over 50 GB/sec peak traffic


Cincinnati Bell Technology Solutions

Problem• Host a dedicated enterprise cloud solution• Large scale VMware environment• Need high availability

Solution• Gluster for VM storage, NFS to clients• SAS drives on back-end• Replication for high availability

Benefits• Storage provisioning from 6 wks. to 15 min.• Vendor agnostic storage• Low cost of service delivery• Elastic growth

• Large scale VM storage

• Low cost service delivery for enterprise customer

• Drastic reduction in provisioning time


Envoy Media

Problem• Limited scalability• Slow response to demand spikes• Manual data management

Solution• Four EBS volumes under Gluster global

namespace• Replication for high availability• EC2 for compute; S3 for backup

Benefits• No change to application• Content immediately available to all servers• Automatic resource allocation• Lower cost (vs. colo and proprietary options)

• Targeted media serving

• 100% AWS hosted

• Unpredictable traffic

Public Cloud: Media Serving on AWS
