Systems and methods for optimizing multiple data streams throughput from single host or storage system to maximize overall throughput

摘要

In one example, a method for determining an optimized data backup throughput rate is provided. The example method includes calculating a total saveset size DS(total) for a backup by summing sizes DS(n) of each of ‘n’ savesets, each of the savesets being associated with a respective savestream, and then calculating a total throughput rate PTP(total) for the backup by summing respective throughput rates TP of each of the ‘n’ savesets. The method further includes calculating a total backup window length PTIME(total) using the following formula: PTIME(total)=DS(total)/PTP (total). Finally, an optimized savestream throughput rate OTP(n) is calculated for each of the ‘n’ savesets using the following formula: OTP(n)=DS(n)/PTIME(total).
