Computer-readable recording medium storing information processing program, information processing method, and information processing apparatus

An information processing method for managing a plurality of storage devices and a plurality of servers, the method comprising:

• while changing a compression ratio setting, obtaining an actual compression ratio by using some of data pieces to be used by the plurality of servers and a decompression rate at which any of the plurality of servers decompresses a compressed dataset in which the some data pieces are compressed;
• determining the compression ratio setting to be used based on a maximum total bandwidth of the plurality of storage devices and a number of the plurality of servers by using the obtained actual compression ratio and the decompression rate for each of the compression ratio settings;
• and
• determining a division number by which the data pieces are to be divided for compression, based on a size of divided data pieces to be used by each of the servers among the data pieces, wherein the size is determined by repeatedly changing the size, compressing the divided data piece, and measuring the actual compression ratio.

An information processing apparatus for managing a plurality of storage devices and a plurality of servers, the information processing apparatus comprising:

• a memory, and
• a processor coupled to the memory and configured to:
• while changing a compression ratio setting, obtain an actual compression ratio by using some of data pieces to be used by the plurality of servers and a decompression rate at which any of the plurality of servers decompresses a compressed dataset in which the some data pieces are compressed;
• determine the compression ratio setting to be used based on a maximum total bandwidth of the plurality of storage devices and a number of the plurality of servers by using the obtained actual compression ratio and the decompression rate for each of the compression ratio settings;
• and
• determine a division number by which the data pieces are to be divided for compression, based on a size of divided data pieces to be used by each of the servers among the data pieces, wherein the size is determined by repeatedly changing the size, compressing the divided data piece, and measuring the actual compression ratio.
