Double-clicking the Track Alignment icon brings up the Track Alignment Settings dialog box.

This feature lets you set dynamic volumes to store blocks of data in alignment with the boundaries of the physical track of the disk. Storing data so that it is aligned with track boundaries helps optimize I/O performance. Check the Enable track alignment support check box to enable the feature for the arrays listed.

You may also check the Show Free Region check box to display additional region information in the Disk View GUI.

The Track alignment settings are shown below.

Arrays not explicitly listed can be enabled as Default. (SFW sets all arrays in the Default category a vendor ID of 'default' and a product ID of 'default'.) This setting may or may not optimize I/O performance for the array. Contact your array manufacturer for details about track alignment and offset values.

You can use the CLI command, vxdisk set track to adjust the setting for track alignment for arrays enabled as Default.
