Agenda


WHAT IS CONSOLIDATION ?

“[Consolidation is] an approach to theefficient usage of server resources inorder to reduce the total number ofservers, increase datacenter density,optimize connectivity, reduce energy andTCO”

IBM BladeCenters are the most efficientway to server consolidation

Higher density and server count per U Integrated network backplane Green technology at best TCO

Reduce Server Count

Increase Datacenter density

Optimize connectivity

Reduce TCO

Green savings


WHAT IS VIRTUALIZATION ?

“[Virtualization is] a technique for hidingthe physical characteristics of computingresources from the way in which othersystems, applications, or end usersinteract with those resources”

In other words: Simplify Complexity

For computing, virtualization can be grouped intwo types:

• Resource virtualization (Storage, Network, etc.)• Platform virtualization (Hypervisor)

Virtualization startedin 1960s by IBM…

Virtual Memory VLAN, trunk, VPN RAID, volume

CONSOLIDATION ? VIRTUALIZATION ?

Consolidation• Higher Density• Better connectivity• Green savings• Management flexibility

Virtualization• Simplified complexity• Resource pooling• Faster deployments• Skyrocket system utilization• Easy high availability

Consolidation & Virtualization• Higher Density• Better connectivity• Green savings• Management flexibility• Simplified complexity• Resource Poolings• Faster Deployments• Skyrocket system utilization• Easy high availability• Simple Management• And even more….

MANAGEMENT

IBM Virtualization Manager (IBM Director)

• Management of both physical and virtual environmentfrom one single console

• Discover and visualize resources and relationships

• Show health and tasks from all resources andrelationships

• Define and monitor health, drill down on problemsquickly to find root cause

• Increase virtual server’s memory, storage, processing,networking capabilities

• Support of VMware, Xen, Microsoft, and others

Easy Management

Heterogeneousenvironment

One stop monitoring


TO BLADE OR NOT TO BLADE ?

No easy answer: be smart !

To Blade• Total infrastructure consolidation• Best when concerned about aggregation• Choose when OS image requires< 8Gb RAM per system• Choose when low power heat is a priority

Not To Blade (3850M2 / 3950M2)

• High-end virtualization• Best when hosting multiple highperformance VMs• Choose when OS image requires> 8Gb RAM per system• Truly scalable perfectly balancedmemory cores and I/O

Success of virtualization is all about sizing

Evolution of Virtualization


Evolution of the Virtual Datacenter


VMware Catalog


VMware ESXi

Server boot to running virtual machines in minutesSimplified managementIncreased security and reliability

Compact, 32MB footprintOnly architecture with no reliance on a

general purpose OSIntegration in hardware eliminates installationIntuitive wizard driven start up experience dramatically reduces deployment timeStandards-based management of the underlying hardware


VMotion

• Hot Migration (VMotion)– Moving a VM that is powered on from one

host to another– Does not move virtual disk(s)– Requires VMotion license

Datastore1

Virtual disk is not moved

Hosts must have compatible CPUs and be on the same network subnet

Hot VM migrations are confined to hosts within the same datacenter


Storage VMotion

• Storage independent migration of virtual machine disks

– Zero downtime to virtual machines

– LUN independent– Supported for Fibre channel

SANs

Minimizes planned downtime due to storage Complete planned downtime management solution across servers and storage with VMotion and Storage VMotion


DRS

• VMware Distributed Resource Scheduler (DRS), continuously monitors utilization across resource pools and intelligently aligns resources with business needs.


High Availability (HA)

• VMware HA allows organizations to minimize downtime and service disruption while eliminating the need for dedicated, stand-by hardware/software. VMware HA also allows organizations to eliminate the need for a devoted administrator to bring back the machines online.


VMware Update Manager

• Automates patch management for ESX Server hosts and select Microsoft and RHEL virtual machines

• Scans and remedies online as well as offline virtual machines* and online ESX Server hosts

• Snapshots virtual machines prior to patching and allows rollback to snapshot

Update Manager

Eliminates manual tracking of patch levels of ESX Server hosts and virtual machinesAutomates enforcement of patch standardsReduces risk through snapshots and offline virtual machine patching

OFFLIN

E


ESX Server Patching with Update Manager and DRS

• Update Manager patches entire DRS clusters

– Each host in the cluster enters DRS maintenance mode, one at a time

– VMs are migrated off, host is patched & rebooted if required

– VMs are migrated back on– Next host is selectedVMotionVMotion

Update Manager server

Automates patching of large number of hosts with zero downtime to virtual machines


Distributed Power Management (DPM)

Resource Pool

Business Demand

Power Off

Consolidates workloads onto fewer servers when the cluster needs fewer resourcesPlaces unneeded servers in standby modeBrings servers back online as workload needs increase

Minimizes power consumption while guaranteeing service levelsNo disruption or downtime to virtual machines


Virtual Desktop Infrastructure (VDI)

Enterprise-class, scalable connection brokerCentral administration and policy enforcementAutomatic desktop provisioning with optional “smart pooling”Desktop persistence and secure tunneling optionsMicrosoft AD integration and optional 2-factor authentication via RSA SecurID®

End-to-end enterprise-class desktop control and manageabilityFamiliar end user experienceTightly integrated with VMware’s proven virtualization platform (VI3)Scalability, security and availability suitable for organizations of all sizes

VMware Site Recovery Manager (SRM)

• Simplifies and automates disaster recovery workflows:– Setup, testing, failover, failback

• Provides central management of recovery plans from VirtualCenter

• Turns manual recovery processes into automated recovery plans

• Simplifies integration with 3rd-party storage replication

Makes disaster recovery rapid, reliable, manageable, affordable
