System for replicating or migrating virtual machine operations log by throttling guest write iOS based on destination throughput

A system comprising:

• memory;
• a virtual machine that writes an operations log of operations performed by the virtual machine to the memory;
• a processor that provides the operations log to a server that is separate from the system;
• a component that detects a write rate of the operations log to the memory and receives a write rate of the operations log on the server from the server;
• a component that obtains a destination write rate based on a destination coefficient associated with delay of writing data to the second server and the write rate of the second virtual machine operations log;
• a comparison component that determines the write rate of the operations log to the memory is less than the destination write rate;
• a rate reduction component that reduces the write rate of the operations log to the memory to a value less that the destination write rate combined with a slowdown coefficient, if the comparison component determines the write rate of the operations log to the memory is greater than the destination write rate;
• and
• a migration component that performs at least one of replicating or migrating the operations log to the server based at least on the reduced write rate.

A computing apparatus comprising:

• a processor;
• and
• a memory device to store computer executable instructions, that when executed by the processor, perform acts comprising:
• detecting a write rate of a virtual machine operations log in memory on a first server;
• providing a first portion of the virtual machine operations log to a second server;
• receiving, at the first server, a write rate of the portion of the virtual machine operations log on the second server;
• obtaining a destination write rate based on a destination coefficient associated with delay of writing data to the second server and the write rate of the second virtual machine operations log;
• determining the write rate of the virtual machine operations log on the first server is greater than the destination write rate;
• if the write rate of the virtual machine operations log on the first server is greater than the destination write rate, reducing the write rate of the virtual machine operations log on the first server to a value less than the destination write rate combined with a slowdown coefficient;
• and
• providing a second portion of the virtual machine operations log to the second server after waiting a predetermined period of time since providing the first portion of the virtual machine operations log.
