Agenda

IT Industry Transformation

IT environments are diverging

Virtualization, Private Clouds and Public Clouds

Convergence

STORAGE REQUIREMENTS

No Vendor Lock-in

Commodity hardware-based

File and Object access to data and unified management

Scale-out and highly available architecture

CONVERGED VIRTUALIZATION AND STORAGE WITH RED HAT

Red Hat Storage

• Store live VM images

• Live Migration of VM

• High Availability

• Common Management

KVM Host

• File is presented directly inside the guest

– No virtual block

– No network roundtrip

• Tenant specific shares• Use-cases

• Virtual NAS • Hadoop on OpenStack• Tenant-private SMB or

Swift services

RHS, RHOS and RHEV INTEGRATION BENEFITS

Scale-out Highly Available Enterprise-ready Open

Page 21: Integration of Storage, OpenStack & Virtualization

RHOS – RHEV integration

Page 22: Integration of Storage, OpenStack & Virtualization

RHOS – RHEV Integration Benefits

● Both provide:

– VM Life Cycle deployment

– VM image repository

– VM Storage services

● OpenStack automates the largest data centers by abstracting virtual resources and the VM lifecycle, in massive scale.

● Both solve similar problems in different ways and work better together like a bass & electric guitar in a rock band...

Page 23: Integration of Storage, OpenStack & Virtualization

RHOS – RHEV Zoom in

● Once you enter a more virtualized use case, is where RHEV is needed to provide a deeper and more complete treatment

● If you drill down the stack, OpenStack doesn't actually create the VM – it invokes hypervisor specific libraries for it (e.g. libvirt)

● RHEV has a full-blown rich Hypervisor that exposes all KVM features as soon as available

● RHEV can also provide advanced virtual storage services to the applications and provide transparently:

– Live Storage Migration

– VM Backup & Restore using Independent Software Vendors*

VM Images

● Red Hat OpenStack can immediately benefit from the availability of RHEV images to the entire Data Center via the Glance-API.

● RHEV users will be able to import Glance images directly.

● Perfect for DevOps use case, where the Dev., QA & Staging are performed on OpenStack & then rolled into Production images in RHEV.

● OpenStack can gain the benefit of more VM images to deploy, while the RHEV image repository can consume, export to and from Glance.

Page 28: Integration of Storage, OpenStack & Virtualization

Summary and Conclusions

● IT is diverging because of business and forces technological trends

● KVM and RHS are essential to connect RHEV, RHOS and Public Clouds

● Benefits

– Integrated and hardened for enterprises–Global support for entire stack – Innovative future that provides more choices
