The correct answer is C. 4 MB. EMC recommended setting for Solaris include that the /etc/system file be modified to include the following parameter: * Set maximum IO size set maxphys = 0x400000 This also requires increase of the maximum I/O size for the disk driver. The corresponding entry and file for this…

Explanation

EMC recommended setting for Solaris include that the /etc/system file be modified to include the following parameter: * Set maximum IO size set maxphys = 0x400000 This also requires increase of the maximum I/O size for the disk driver. The corresponding entry and file for this change are different for different Solaris versions, as follows: For Solaris 10 (SPARC): File: /kernel/drv/ssd.conf Setting: ssd_max_xfer_size=0x400000; For Solaris 10 (x86): File: /kernel/drv/sd.conf Setting: sd_max_xfer_size=0x400000;
