and click Exposé & Spaces. Now uncheck Show Dashboard as a Space at the

bottom of the screen.

Podcast Composer

You can use Podcast Composer to create and edit podcast workflows. It

guides you through the required steps, where you can choose titles, videos,

and effects for a podcast. See Chapter 15 for more about creating podcasts

and workflows with Lion Server.

Server Monitor

Server Monitor lets you keep tabs on Apple’s Xserve server hardware. Apple dis-

continued Xserve in early 2011, but you can still run Lion Server on it. Server

Monitor can display a graph of the internal temperature of one or more Xserve(s),

list warnings and failures, display the power usage, and show how much hard

drive space and memory are in the Xserves on your network. You can set Server

Monitor to send you an e-mail message if it detects a hardware problem in an

Xserve box. (You can read more about Xserves and Lion in Chapter 3.)

If you have Lion Sever installed on another type of Mac, you won’t have any

use for Server Monitor. You can safely delete it.

System Image Utility

You can use System Image Utility to create Mac OS X disk images to be used to

boot Macs from the server with NetBoot or to install on multiple Macs with

NetInstall. (See the “NetBoot” and “NetInstall” sections, earlier in this chapter.)

You can create a NetInstall or NetBoot disk image in two steps, or you can

customize settings to include your own items in the disk image. You can also

include a Boot Camp partition in a disk image if you want a client Mac to have

the option of booting with Microsoft Windows.

Xgrid Admin

Xgrid Admin is designed to monitor arrays of Macs working together as one

entity. The most practical use that Apple gives is with Podcast Producer,

which can use Xgrid to spread the work of processing video across multiple

Macs automatically. Xgrid Admin enables you to monitor an Xgrid and to

manage computing jobs that are going on.

Apple includes Xgrid Admin along with the more everyday server adminis-

tration tools, almost as a dare to find out what you can do with it. If you tie

together enough Macs, you can have ordinary user Macs by day and the com-

bined power of a supercomputer by night. Stanford University uses an Xgrid

of several hundred Macs to perform complex calculations related to molecu-

lar physiology and pharmacology.
