Link Partitioner : It actually splits data into various partitions or data flows using various partition methods .
Link Collector : It collects the data coming from partitions, merges it into a single data flow and loads to target.
Server jobs mainly execute the jobs in sequential fashion,the ipc stage as well as link partioner and link collector will simulate the parllel mode of execution over the sever jobs having single cpu Link Partitioner : It receives data on a single input link and diverts the data to a maximum no.of 64 output links and the data processed by the same stage having same meta dataLink Collector : It will collects the data from 64 inputlinks, merges it into a single data flowand loads to target.

Link Partitioner
All the jobs in a server are executed sequentially
The simulation of parallel mode of execution over other server jobs is done by Partition and Link Collector.
Data is received by Link Partitioner on a single input link and diverts to a maximum of 64 output links
Data is Processed by the same stage
It actually splits data into various partitions or data flows using various partition methods .
Link collector:
Data from 64 input links is collected by Link Collector and merges into a single data flow
Link collector loads the collected data to the target.
All these data stages are active
The design and execution mode of server jobs are decided by the designer.
It collects the data coming from partitions, merges it into a single data flow and loads to target.
