Active active data center technologies the why
Active / Active Data Center Technologies – The Why

  • Active / Active load balancing between data centers

    • Deployment similar to Web Server Farms using integrated load balancing technologies

  • Federated management of multisite IT Environment

  • Seamless application and VM mobility across sites

  • Improve BC/DR RPO/RTO for Mission Critical Workloads

Active active data center technologies deployment considerations
Active / Active Data Center Technologies Deployment Considerations

External Appliance 4-Way Cluster – Requires 64 SAN FC Ports to Implement

Embedded Storage Virtualization within the Array – Requires Enough Ports to

Handle Throughput – No Scale-out Penalty


Active active data center technologies server or rack outage
Active / Active Data Center Technologies ConsiderationsServer or Rack Outage

Server or Rack Outage – VMotion to local server within the local cluster- Only requires SAN connectivity. No Active / Active technology required

Active / Active Data Center Technologies ConsiderationsData Center Outage - Alternative

Data Center Outage – For environments requiring automated recovery over extended distance or 3DC or 4DC DR capabilities support may be limited or additional products may be required

VMotion Based Load Balancing –

Cost and effort required to VMotion VMs to balance underutilized servers may not provide an ROI that surpasses cost to deployment . Technologies such as x86 Blade Server based Logical Partitioning which allows execution of Production, Q & A, and Test workloads on a common physical server may provide a better was to drive utilization across servers


Active active data center technologies actual value
Active / Active Data Center Technologies ConsiderationsActual Value

Active / Active Data Center “True Value” –

The environments that can truly justify an Active / Active Deployment are Mission Critical Application that cannot tolerate any loss or disruption of access. However, most customers are hesitant to run these types of workloads on a hypervisor and if they did they typically would not allow VM Administrators to modify configurations (VMotion) during processing hours


Active active data center technologies deployment cautions
Active / Active Data Center Technologies ConsiderationsDeployment Cautions

  • Technologies may throttle performance of high-end storage arrays thus negativity impacting their performance and value

    .

  • Networking implementation costs must be considered and can increase cost and complexity

  • Quorum Disk may not function over extended distances

  • Costs associated with deploying Active / Active Data Center Technologies may exceed the Return on Investment if not done prudently

  • Active / Active Data Center Technologies may require customers also deploy additional technologies in support of Disaster Recovery
