Quick Start Guide for Tempo SATA E4i
Mac OS X Drive Formatting—RAID Sets
This section describes the process of formatting (initializing) multiple hard
drives connected to the Tempo SATA E4i using Disk Utility under Mac
OS X Version 10.5; the process is nearly identical under Mac OS X Version
10.4. If you choose to do so, you may format your drives using SoftRAID
3.1 or later; refer to that product’s documentation for instructions.
1. Turn on your computer. During startup, one or more messages
referring to unreadable volumes will be displayed; click Initialize…
to launch Disk Utility. After Disk Utility launches, click the Initialize
button in each remaining message window.
2. If it is not already open, launch Disk Utility (Figure 4). Note that
all drives attached to the Tempo card may be identified in the
information window by their custom icon with the Sonnet S logo.
3. Select one of the drives you want to format in a RAID set by
clicking the drive symbol or the “name” of the drive; a set of tabs
will appear in the right pane. Click the RAID tab, select all the
drives you will use to create your striped RAID set, and then drag
them into the disk field
(Figure 5). Be careful NOT to accidentally
drag in a drive you don’t want included in the RAID.
4. From the drop-down menus, select the volume format and the
RAID scheme (Striped RAID Set), and then type in the name for
your RAID volume
(Figure 5).
5. Click the Options button. From the drop down menu, select a
RAID block size (Figure 6). If you are working with video, selecting
the largest block size will help improve performance. If you are
working with many smaller files (databases, etc.) a smaller block size
will work well. Click OK.
6. Click Create. When the Creating RAID window appears, click the
Create button; all of the selected drives will be formatted and the
RAID volume created. Close Disk Utility; your drives are now ready
for use and your installation is complete.

Support Notes: The remaining steps in this section describe the
creation of a RAID 0 (striped) set. If you intend to create a RAID 1
(mirrored) or RAID 10 (striped/mirrored) set, the procedure is similar to the
remaining steps. Please refer to Disk Utility help for further information.
Support Note: See page 8 for the Tempo SATA E4i card’s port
and channel identification information.
