US 2018/0324250 A1 · STORAGE NETWORK TIERING

Abstract

Methods and systems for storage network tiering are provided. One method includes receiving input/output (I/O) requests from a set of client devices via one of a plurality of communication paths and performing I/O operations on data in one or more storage devices based on corresponding I/O requests. The method further includes determining locations storing each data set in the one or more storage devices and transmitting, to the set of client devices, recommendations of a communication path in the plurality of communication paths for transmitting subsequent I/O requests that access a particular data set based on the location storing the particular data set. Systems and computer program products for performing the above method are also provided.

Dependent claims

An apparatus, comprising:

an input/output (I/O) module that receives I/O requests from a set of client devices and performs I/O operations on data in one or more storage devices based on corresponding I/O requests, wherein each respective I/O operation is performed via one of a plurality of communication paths based on instructions from a client device issuing a corresponding I/O request;
a location module that determines locations storing each data set in the one or more storage devices;
and
a response module that transmits, to the set of client devices, recommendations of a communication path in the plurality of communication paths for transmitting subsequent I/O requests that access a particular data set based on a location storing the particular data set,
wherein at least a portion of said modules comprise one or more of hardware circuits, a programmable hardware device, and executable code stored on one or more computer-readable storage media.

2 more elements

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

receive input/output (I/O) requests from a set of client devices via one of a plurality of communication paths;
perform I/O operations on data in one or more storage devices based on corresponding I/O requests;
determine locations storing each data set in the one or more storage devices;
and
transmit, to the set of client devices, recommendations of a communication path in the plurality of communication paths for transmitting subsequent I/O requests that access a particular data set based on a location storing the particular data set.
