Performance & Scalability

• Fast:

– Need to virtualize with the lowest “penalty” possible

– Price:Performance: Doing the most with the least hardware

– Be completely transparent to the business and users

• Scalable:

– Need to achieve high consolidation ratios

– Maintain high performance even with many VMs per server

• Reliable, consistent, predictable:

– Consistent performance over time

– Architectural isolation to prevent impact from “neighbor” VMs

– Capacity plan accurately

• Scalable management too: Scale your people easily

It’s Important

Oracle VM 3.0

• Foundation for Application-Driven Virtualization

– Virtualization engineered for application-centric architectures

• Designed to virtualize all of your data center applications

– Designed from the ground up for better scalability, manageability, and

ease-of-use

– Completely new management stack allowing central management of the

entire platform

• Introduces new capabilities for full stack management

– Making applications easier to deploy, manage, and support

Server Scalability

• Xen-based server architecture

– Modern, low-overhead x86 virtualization

– Support for paravirtualized operating systems and timer architecture

– Results in low-overhead, high-performance and scalability

• The latest hypervisor: Xen 4.0

– Allows 128 vcpus and 1 TB of RAM per guest

– Support for latest hardware features from Intel and AMD

• Support for the latest hardware based on the Linux 2.6.32 kernel

• Ability to manage resource priorities and caps between VMs

Network Scalability

• Optionally separate and dedicate networks– Guest IP network:

• Isolate from high storage I/O

– HA heartbeat:

• Reliable scalability under heavy load

– Live Migration:

• Ad hoc migrations won’t affect other guests

– Storage:

• Heavy I/O won’t compete with guest IP traffic

– Management:

• Maximum performance, scalability, reliability

• Excellent isolation to support high scalability and predictable performance

Storage Scalability

• Oracle Cluster Filesystem 2 (OCFS) v1.8

– Included with Oracle VM 3.0: no additional license

– Enhanced performance

• “Instant” thin-provisioned cloning with OCFS2

– Ready-to-start clones in about 1 second

– Copy-on-write clones for any OCFS2 LUN

– Clones immediately independent and can execute simultaneously on

the same- or different server vs. “original” copy

• Or remove a clone anywhere in the chain at any time without having to

“collapse” the chain of copies

Storage

Guest OS Scalability

• Support for bigger VMs:

– 128 vCPUs with CPU overcommit support

– Up to 1 TB of RAM per guest with ability to hot-add memory

• Ability to manage resource priorities and caps between VMs: CPU and memory caps per VM

• Support paravirtualized and hardware virtualized guests(with- or without PV drivers)

– Paravirtualization means virtualization-aware operating systems for lower

overhead and higher scalability

• Rapid VM creation options:

– Support for Hot Clone – clone a running VM

– Create VMs from pre-built Templates: ready-to-run applications

Server

Pool 1

• Dynamic loadbalancing

– On start-up…

• Automatically identifies the best server for hosting VM(s)

– Dynamically at run-time…

• Dynamic Resource Scheduling (DRS)

• Admin policy-based trigger

– Algorithms determine best destination host server

• High availability clustering up to 32 physical nodes

– Auto-restart failed VMs after server or VM failure
