RED HAT GLUSTER STORAGE
VS.
TRADITIONAL STORAGE APPLIANCES

THE SOFTWARE DEFINED STORAGE
LITMUS TEST
HARDWARE
INNOVATION
• Can I repurpose existing industry-standard servers as storage servers rather than buy new
hardware?
• Can I run my storage clusters on a heterogeneous mix of server brands?
OPERATING
EXPENSES
• Can innovations in storage controller software be delivered independently from hardware
upgrades?
• Am I limited by my vendor’s ability to validate new storage features and hardware advances?
• Can I grow my storage cluster in small increments (e.g., by a few servers at a time) or am I
limited to the increments defined by the vendor (e.g., quarter, half or full rack)?

WHY GO GLUSTER FOR FILE STORAGE?
1. Cost effective, at scale
2. Choice of deployment environment (bare metal, VM, container, cloud)
3. Industry standard hardware and flexible choice
4. Performance and Sizing Guides for optimal hardware selection
5. Granular updates (incl. security fixes)
6. World class, open source platform (RHEL, XFS)
7. All features included, no hidden costs for add-on features
8. Skills reuse (leverage existing Linux skills set)
9. Simple pricing model
10. Tested, trusted Support & Services

3 Year TCO
(incl. support)
THE PROOF - TCO COMPARISON
Throughput
Configuration
• HDD-only media
• Higher CPU-to-media
ratio than archive
configurations
• 2x replication with RHGS
• 8:3 Erasure Coding with

READING THE FINE PRINT
WHAT THEY SAY WHAT IT MEANS TO YOU
We can reach x% of raw capacity for increased
storage efficiency
• The amount of usable capacity is proportional to the data protection
schemes (N+1…N+4).
• If you use a protection scheme, you may find that x% of raw capacity may
not be attainable
Our advanced software features are available in
bundles, simplifying configuration and reducing
cost.
• Software licensing within a cluster is per node, and costs for bundles and
features vary by the node type, and its configuration.
• Licenses are not transferable across node types, adding complexity in the
long term
We offer software defined storage too! • Do you have choice of hardware?
• Are you essentially running a virtual machine with a hypervisor?

  • #2: What is sds, market dynamics driving the demand for sds, gluster
  • #3: In some ways storage has always been. Everyone is sw defined. Buzz. Litmus Test? Not sw define for the sake of it but to truly realize the benefits.
  • #10: SD Edge: https://www.emc.com/collateral/data-sheet/h14759-ds-isilonsd-edge.pdf
