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

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

Data 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

Actual 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

Deployment 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
