US 2015/0312126 A1 · Maximizing Storage Controller Bandwidth Utilization In Heterogeneous Storage Area Networks

Abstract

A storage area network controlled, part, by performing the following steps: (i) for each host link of a plurality of host links in a storage area network (SAN), determining a maximum possible data transfer rate; (ii) for each host link of a plurality of host links in a storage area network, determining a maximum permitted data transfer rate based on the maximum possible data transfer rate; (iii) making a plurality of data transfers, through SAN fabric of the SAN and between a storage controller module of the SAN and various host links of the plurality of host links; and (iv) for each data transfer, controlling the data transfer so that a data transfer rate for the data transfer does not exceed the maximum permitted data transfer rate.

Dependent claims

A method comprising:

for each host link of a plurality of host links in a storage area network (SAN), determining a maximum possible data transfer rate;
for each host link of a plurality of host links in a storage area network, determining a maximum permitted data transfer rate based on the maximum possible data transfer rate;
making a plurality of data transfers, through SAN fabric of the SAN and between a storage controller module of the SAN and various host links of the plurality of host links;
and
for each data transfer, controlling the data transfer so that a data transfer rate for the data transfer does not exceed the maximum permitted data transfer rate.

A computer program product for storing and accessing data, the product comprising a computer readable storage medium having stored thereon:

first program instructions executable by a device, to cause the device to, for each host link of a plurality of host links in a storage area network (SAN), determine a maximum possible data transfer rate;
second program instructions executable by a device, to cause the device to, for each host link of a plurality of host links in the SAN, determine a maximum permitted data transfer rate based on the maximum possible data transfer rate;
third program instructions executable by a device, to cause the device to make a plurality of data transfers, through a SAN fabric of the SAN and between a storage controller module of the SAN and various host links of the plurality of host links;
and
fourth program instructions executable by a device, to cause the device to, for each of the plurality of data transfers, control the data transfer so that a data transfer rate for the data transfer does not exceed the maximum permitted data transfer rate.
