Draft Document for Review March 28, 2011 12:24 pm 7914Admin_Physical.fm
10.2 Discover component properties and location
In the left Physical pane you can see schematic layout of physical enclosures of DS3500
Storage Subsystem. In Figure 10-1 on page 264, a subsystem with DS3524 controller
enclosure for 24x 2.5 inch disk drives, and one attached EXP3512 expansion enclosure for
12x 3.5 inch disk drives and displayed. You can align this layout to real placement in your
rack, as described in “Enclosure Order” on page 208.
10.2.1 Show disks type
In the upper part of the Physical pane you can see one or two click buttons. First one is for
selection of SAS disks, second one is for SED (Self Encrypted Disk) SAS disks. Encrypted
disks are known also as FDE (Full Disk Encryption), so the button name is “Show FDE”. At
the time of writing this book, only SAS drives are available for DS3500, so if you click “Show
SAS disk” button, all disks are marked as in Figure 10-2.
Figure 10-2 SAS disks selection
If you click “Show FDE” button, some of disks which were selected as SAS is marked again
as you can see in Figure 10-3.

More information about disk encryption you can find in Chapter 15, “Disk Security with Full
Disk Encryption drives” on page 449.
10.2.2 View Enclosure Components
The second line in the Physical pane is blue link, which opens a new window with detailed
information about hardware components of specific enclosure (Figure 10-4 on page 266). If
you select the buttons on the bottom of the window, you can also locate this enclosure in rack
(blue LED diode starts to blink) or you can change enclosure ID. Refer to “Enclosure ID” on
page 208 for more details.
