  • This animated walkthrough covers the basic 10 steps to understand the basics of a clusterDeploy redundant hardware everywhere“Shared” storage accessible by all nodesClustered application writes data to shared storage so all nodes can assess itA registry hive containing current cluster configuration information is replicated to each nodeNodes monitor the health of other nodesIf a node fails, the health check will fail, and a failover will happenAnother node knows what the failed node was hosting through the registry and start that applicationThe application reads its saved data from the shared storageClient connects to app on new nodeClients may experience a slight interruption in service during failover but none during a live migration (of a VM)
  • VMM Availability Groups: http://technet.microsoft.com/en-us/library/jj628165.aspxAACN allows VMs to be forced to be distributed as much as possible, for example the 4 “blue” VMs will spread across the 4 nodes. The 6 “red” VMs will spread across the 4 nodes as optimally as possible, with 2 nodes having 2 VMs.If there are more VMs with the same AACN, there will be more than 1 VM per nodeConfigurable through PowerShell or Cluster.exeUseful to avoid having a single host take down a key piece of infrastructure which is running in VMs. If all the virtualized DCs are on the same host, then losing that host will take down the entire infrastructure, so it is optimal to spread them out so that losing a single host will not take down all DCs.

Health & Human Services • Theft of 57 hard drives that contained protected health information (ePHI) for over 1 million individuals • Secured by: • Security Patrols • Biometric scanner • Keycard scanner • Magnetic locks • Keyed locks “71% of health care organizations have suffered at least one data breach within the last year” -Study by Veriphyr
