5. Commercial solutions
Hypervisor license - depends on CPU and/or memory
Orchestrator license - live migration, HA, backup, …
Certified hardware – limited hardware supported
Centralized storage system – needed for HA

6. Our Open solution
Open hypervisor
it comes with Linux kernel in standard distro
Orchestrator
live migration, ha, backup, … intuitive and web based
Commodity hardware
only very low requirements needed
No centralized storage system
special network filesystem is used instead physical storage

9. Open hypervisor
Freely available: on your GNU/Linux
distribution;
Enterprise-ready: powerful mix of enterprise
features and a rich set of partners.
Support: widest range of hardware without
hassles (Thanks Linux!)
High-performance: top-level virtualization
benchmarks for Windows and Linux workloads.

10. Open VM management software
OpenNebula
Adaptable: highly modular.
Proven: massive scale production
environments;
Interoperable: XML-RPC, EC2, OCCI
Proxmox
Easy to deploy: ISO installer or from bare
Debian
Easy to use: centralized web management

11. Low-end hardware requirements
The simplest virtualization host is...
your laptop:
CPU with virtualization extensions;
A bunch of available memory
A bunch of available disk space
Use your workstations to prepare VM
before starting them in production.

12. Focus on storage
Shared storage is not an option for live
migration and High-Availability.
A good storage solution:
Availability: the sky should not fall on our heads;
Scalability: we add new bricks when needed;
Price.
Common choice is to use a dedicated
NAS/SAN (NetApp, EMC, QNAP and so on).

13. Our choice: GlusterFS
GlusterFS is an open source distributed
network filesystem.
How it works?
Aggregate available disk space on your
hosts;
Replicate data: HA and prevent data-loss;
Data available via LAN with standard
protocols: FUSE, NFS, CIFS.

14. GlusterFS advantages
Scalability: to Petabytes and beyond!
Affordability: use commodity hardware;
Flexibility: deploy in any environment;
Linear performances: no degradation;
HA: replicate data on multiple places;
Unified namespace: like a folder on a
local disk
