7. Performance and Scalability
Red Hat provides the most scalable and high performance virtualization platform
 Para-virtualization (optimized kernel) provides best virtualization performance
● RHEL guests typically run 20% to 100% faster on RHEL than on traditional
virtualization solutions
● Some workloads can see up to a 400% performance improvement
● Any workload can be virtualized even highly IO intensive – eg, databases
 Full Virtualization
● RHEL provides enhanced drivers for fully virtualized guests
● Includes Linux and Windows virtual machines
● “Para-virtualized drivers”
● Significant performance increases with fully virtualized guests

8. Benefits of Red Hat Virtualization
RHEL provides the most scalable and flexible Virtualization platform
● Allows organizations to virtualize all work loads
● Removes barriers to virtualizing high performance enterprise applications
● Eliminates the economic constraints on virtualization
● Virtualize any workload without added cost
● Reduces complexity
● Deploy a single platform that covers all your virtualization need
● Includes support for Windows XP, 2000 and 2003
● Use consistent tools to deploy, manage and deploy your entire
infrastructure

9. libvirt
 Provides a standard management interface
● Hypervisor agnostic
● Will work with multiple hypervisors
● Stable API
● Shield users from hypervisor changes
● Consistent tools across hypervisors
● eg. Same interface for Xen, QEMU, KVM, OpenVZ, etc
● Scriptable
● Provides APIs for developers / tool vendors
● Allows vendors to build cross platform tools

13. Virtualization Alone is Not Enough:
Challenges and Requirements for Today's
Large-Scale Computing
 Most enterprises are running more and more distributed applications and
workloads and dealing with an increasing amount of distributed data
 Many enterprises have increasing demands for computing power while
simultaneously needing to cut down on physical resource consumption (e.g.
power, space)
 Many enterprises have variable needs for their amounts of computing power
● Virtualization and consolidation can only get you so far if you have
significant variability in computing requirements or server loads
● Some enterprises can never get enough computing capacity
13

14. Promises and Challenges of Cloud Computing
● Cloud computing promises to deliver many of the benefits of virtualization via an
external provider
● Flexibility, scalability, on-demand utilization, efficiency, etc.
● Many companies are looking at a variety of cloud-based offerings to address their
IT Infrastructure challenges
● Research: Folding@Home, BOINC, Fedora Nightlife
● Enterprise: Amazon EC2, Google App Engine
● There are important issues to consider when evaluating cloud infrastructure,
including:
● Do I need to integrate the services with anything local in my datacenter or organization?
● Do I have any particular requirements about data security?
● How large are my datasets?
● Are there any issues with platform lock-in?
● Do I have any requirements or SLA's for how quickly my results return?
● Do I want to add capacity to my IT infrastructure or outsource my IT infrastructure?

● Integrated platform for high
performance distributed
computing
● High speed, interoperable,
open standard Messaging
● Deterministic, low-latency
Realtime kernel
● High performance & throughput

16. About MRG Grid
● Brings advantages of scale-out and flexible deployment to any application
● Delivers better asset utilization, allowing applications to take advantage of all
available computing resources
● Dynamically provisions additional peak capacity for “Christmas Rush”-like
situations
● Executes across multiple platforms and in virtual machines
● Schedules from sub-second jobs to long-running batch jobs
● Provides seamless and flexible High Throughput Computing (HTC) and High
Performance Computing (HPC) across
● Local grids
● Remote grids
● Remote clouds (Amazon EC2)
● Cycle-harvesting from desktop PCs
16

17. MRG Grid is Based on Condor
● MRG Grid is based on the Condor Project created and hosted by the University of
Wisconsin, Madison
● Red Hat and the University of Wisconsin have signed a strategic partnership
around Condor:
● University of Wisconsin makes Condor source code available under OSI-approved open
source license
● Red Hat & University of Wisconsin jointly fund and staff Condor development on-
campus at the University of Wisconsin
● Red Hat and the University of Wisconsin's partnership will:
● Add enhanced enterprise features, management, and supportability to Condor and MRG
Grid
● Add High Throughput Computing capabilities to Linux
17

18. Red Hat is Initially Adding to Condor:
● Enterprise Supportability
● Break out Condor from statically-linked blob to multiple well-maintained and
individually patchable rpm's
● Web-Based Management Console
● Unified management across all of MRG for job, system, and workload
management/monitoring
● AMQP Messaging Integration
● Enable job submission to Condor via AMQP Messaging clients
● Enable sub-second, low-latency scheduling for sub-second jobs
● Virtualization Support via libvirt Integration
● Support scheduling of virtual machines on Linux using libvirt API's
● Amazon EC2 Integration
● Enable automatic EC2 provisioning, job submission, results storage, teardown via
Condor scheduler
● Runs as a job, so it can be a dependency for other jobs or executed based on rules
(e.g. add capacity in EC2 if local grid out of capacity)
18

19. Automating Virtualization with Red Hat
Enterprise MRG
 MRG's Grid Scheduler can automatically and fully manage virtual machines via
libvirt: start, stop, migrate, etc
 Integrating virtualization with MRG enables enterprises to:
● Dynamically partition their data center based on workload priorities and load
● Drive higher utilization by leveraging Condor's Compute On Demand to
schedule lower priority jobs onto idle servers
● Drive higher utilization by optimizing resource matching via virtualization.
e.g. Schedule a Windows job onto a Linux resource
● Schedule virtual machines onto idle desktop workstations and live migrate
them to other machines when the workstations are no longer idle
Red Hat Enterprise MRG builds on Red Hat's integrated virtualization
to provide the tools to build your own internal cloud
and treat your IT infrastructure as a generic computational grid
19

20. MRG and Amazon EC2: The Most Flexibility
and Best of all Worlds for Grid Deployments
● Transparently move between or blend local grids with cloud-based grids
● Red Hat Enterprise Linux application certifications hold whether local or in Amazon EC2
● Red Hat Enterprise MRG provides a unified management interface across local grids,
remote grids, and the cloud
● Dynamically add capacity in EC2 to dedicated grids where there is a need
to maintain local infrastructure but there is a desire for flexible capacity
● e.g. Financial Services, Government, Healthcare
● Schedule entirely in EC2 through MRG when you only have occasional
needs for grids. Easily add local capacity to your MRG Grid when
necessary
● e.g. Internet, Manufacturing, Research
● No lock-in to local or cloud infrastructure
