MISSION CRITICAL WORKLOADS

Windows Server 8 – Developer Preview

MEMORY STORAGE NETWORK PROCESSOR

MEMORY STORAGE NETWORK PROCESSOR

FLEXIBLE

High Medium

Low

• VM Health Monitoring detection inside virtual machine

• Clustering in the host identifies app failures and takes

recovery action 1. Host level HA recovery

• Failover Clustering fails over VM to another node

2. Guest level HA recovery

• Failover Clustering Reboots VM

3. Application level recovery

• Service Control Manager (SCM) or event triggered

• Generic health monitoring for any application – Monitor services through Service Control Manager

– Generation of specific Event ID’s • ISV opportunity to leverage GuestSetCriticalState() with to integrate 3rd party

application monitoring solutions in the VM

APP

According to Gartner about 1/3 companies use outside

companies to dispose of PCs & Servers

ENCRYPTED CLUSTER VOLUMES



Hyper-V Replica

Affordable

Simple to configure

Works with your current

hardware

Comes in the box in Windows 8

Single wizard setup

All you need is two connected

servers

No Guest dependencies
