GDC Simulator Architecture

GDC Simulator AvailabilityAvailability:

○ GDC Downtime Spectrum○ GDC Sites complementary property○ GDC Read-only Data Availability○ GDC Data Replicates Guidance

Input/Output of Simulator External Input:

○ Each site green power input○ Client request input

Internal Configuration:○ data placement policy○ data replica policy

Output:○ GDC Downtime○ Client Request Failure Rate○ GDC Throughput

GDC Simulator - In ProgressData Request from Power Supplier

○ solar and wind sites for each available State ○ The eastern half of the lower 48 states○ For a number of years○ Both observed and forecasted power

Coding in progress○ Google Code○ GPL v3

Client Request API Defined○ For application workload simulator

Work Assignment○ Event Framework--Long Zhang○ Failure Strategy--Long Zhang○ Cloud/DataCenter(process)--Hao Jiang○ DataBlock--Hao Jiang○ Downtime Spectrum--Vinay Soni○ Workload Modification--Vinay Soni○ Workload supply(twitter)--Brian Devins

Future Work● Get more workload from twitter● Add consistency to the simulator● Simulate the power consuming of data center(optional)
