We Improve Data Center Operational Efficiency
 Reduced OPEX and Improved Customer Satisfaction
• Automation of Fiber Infrastructure speeds new service provisioning, improves
customer satisfaction and retention, supports creation of new on-demand services,
improves reliability, eliminates truck-rolls, and lowers workforce cost.
 Reduced CAPEX & Improved Energy Efficiency
• Compute resources can be reallocated and shared at the optical layer, supporting
much improved % utilization of server and storage assets. These represent 85% of
the DC electronics cost and almost 70% of the energy consumption.
Enabling “Lights Out” Data Centers

Problem: Poor Compute Resource Utilization
The biggest operational efficiency problem in Data Centers
Amortized Equipment Cost 1 Power Consumption 2

Compute Resources = 85% of Electronics Cost & 68% of Energy
Problem: Compute Resources are typically less than 40% utilized
Massive CAPEX
& Energy Waste

CALIENT Improves DC Compute Utilization
Supports Pooling and Sharing of Expensive Server Resources
Compute Resources are physically shared between PODs
in response to Application/Workload demands
 Data Centers use convenient POD-based architectures that
simplify deployment and maintenance
 However PODs restrict resource agility for large workloads
and result in poor compute utilization – less than 40%
 CALIENT Optical Circuit Switches support physical
virtualization allowing compute resources to be shared
between PODs for maximum efficiency
Economic Benefit of CALIENT OCS
 Model assumes $2B in mega-scale data center
spending
 A server utilization increase of less than 10% is
equivalent to saving the total CAPEX of the entire
data center network
Savings is in the $100Ms for a Mega-scale Data Center

Further Benefits of Optical Network Automation
 Accelerate New Service revenue
• Provision in seconds instead of days
• Create and reallocate capacity on demand
• Enhance customer satisfaction and retention
 Reduce Operational Expense
• Reduce on-facility workforce and truck-rolls
• Manage connections from a central offsite operations facility
• Support automated entry and updating of facility electronic records
 Improve Quality of Service
• Minimize human-error scenarios
• Accelerate fault detection and isolation during service degradations or outages
