Storage area network multi-pathing
First Claim
1. A method for network multi-pathing, comprising:
- maintaining paths to a storage system through a first network type and a second network type, wherein the first network type has a higher Input/Output (I/O) per second performance characteristic than the second network type;
receiving an I/O request;
determining a length of the I/O request;
sending the I/O request on one of the paths to the storage system through the first network type in response to determining that the length of the I/O request is below a threshold length; and
sending the I/O request on one of the paths to the storage system through the second network type in response to determining that the length of the I/O request is above the threshold length.

Abstract
Provided are a method, computer program product and system for network multi-pathing. Paths to a storage system are through a first network type and a second network type. The first network type has a higher Input/Output (I/O) per second performance characteristic than the second network type. A length is determined from a received I/O request. The I/O request is sent on one of the paths to the storage system through the first network type in response to determining that the length of the I/O request is below a threshold length. The I/O request is sent on one of the paths to the storage system through the second network type in response to determining that the length of the I/O request is above the threshold length.
