Embodiment Construction

[0019] figure 1 is a block diagram of a multi-path environment (ie, data center) 100 including a plurality of storage ports S1-S6 (collectively S) with variable processing capabilities, according to an example embodiment of the invention. Such as figure 1 As illustrated in , storage system 160 may provide storage volume 175 for use with multiple hosts (eg, host 1 105 1 and host 2 105 2 ) (collectively referred to as 105) I / O operations. Hosts 105 can utilize multipathing drivers 110 at each host 105 1 、110 2 Managed port selection (collectively 110 ) is communicatively coupled to volume 175 via a plurality of paths from respective host ports H1-H6 through a plurality of storage ports S1-S6. Such multi-path storage environments 100 are typically deployed with redundancy for enterprise purposes. Such as figure 1 As illustrated in, the host 105 1 There are 6 paths to volume 125 (i.e. H1 / S1, H2 / S2, H3 / S3, H4 / S4, H3 / S5, and H5 / S6), and host 105 2 There are 3 paths to volum...

Abstract

Example embodiments relate to a method, a system, and a computer program product for load balancing for port selection. The method includes determining a processing load for each storage port in a plurality of storage ports having variable processing power and calculating a delay characteristic for each storage port of the plurality of storage ports according to its processing load. A command then may be sent to a selected storage port of the plurality of storage ports according to the delay characteristics and a policy.

Description

[0001] Portions of the disclosure of this patent document may contain command formats and other computer language listings, all of which are protected by copyright. The copyright owner has no objection to anyone's facsimile reproduction of the patent document or the patent disclosure as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyright whatsoever. technical field [0002] The present application relates to storage path management, and more particularly to load balancing for port selection in a multipath environment. Background technique [0003] Enterprise storage systems store data in large environments and differ from consumer storage systems in both the size of the environment and the type of technology used to store and manage the data. Storage area networks (SANs) are commonly used in enterprise storage systems to transfer data between computer systems and storage devices. A typical SAN provides a communications...
