Dell EMC Exam E20-526 Topic 9 Question 33 Discussion

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;

Etc.
