Creating and Using Simple Volumes Simple volumes are the default volume type on a dynamic disk. Use simple volumes in the fol- lowing situations: ■ You only have one disk in a machine. ■ You are not concerned with fault tolerance. ■ You want the ability to dynamically extend the space used on a volume. Use the following steps to create a simple volume 1. Right-click the unallocated space on the disk on which you want to create a simple volume. 2. Click New Volume on the context menu.This will start the New Volume Wizard, shown in Figure 5.42. 3. Click Next to continue. 4. On the Select Volume Type window (Figure 5.43), select Simple. 5. Click Next to continue. 136 Chapter 5 • Managing Physical and Logical Disks Figure 5.42 Creating Simple Volumes Figure 5.43 Selecting Volume Type 301_BD_W2k3_05.qxd 5/12/04 12:32 PM Page 136 6. You will next be prompted to select the disk to use for the simple volume, as shown in Figure 5.44.The correct disk should already be selected. If not, select it. 7. Select the amount of space to be used for the simple volume and click Next to continue. 8. Next you need to identify your new volume. Select a drive letter or choose to mount the new volume to an NTFS folder. For this example, we assign the new volume the drive letter D, as shown in Figure 5.45 9. Next, you can format your new volume.You can format the volume as FAT, FAT32, or NTFS, or you can choose not to format the volume now. For this example, choose NTFS, as shown in Figure 5.46, and click Next to continue. 10. You will now see the Completing the New Volume Wizard window, as shown in Figure 5.47. Read over the summary to verify that you made the correct selections and click Finish to complete the process.

However, only one disk in the volume is written to at a time. Spanned volumes can be created using two to 32 disks. Spanned volumes provide 100 percent drive utilization (minus the 1MB per disk overhead for the LDM partition). Use spanned volumes in the following situations: ■ You want to access multiple disks as a single volume and you are not concerned about fault tolerance or increased read/write performance. ■ Your disks are different sizes and you want to achieve 100 percent drive utilization with a single volume. ■ You have a simple volume that is almost full and you need to expand it across multiple disks. 138 Chapter 5 • Managing Physical and Logical Disks Figure 5.46 Formatting Your New Volume Figure 5.47 Finishing the New Volume WizardCreating and Using Spanned Volumes 301_BD_W2k3_05.qxd 5/12/04 12:32 PM Page 138 Create a spanned volume 1. Right-click the unallocated space on the disk on which you want to create a spanned volume. 2. Click New Volume on the context menu.This will start the New Volume Wizard,as shown in Figure 5.48. 3.

Ideally, your disks will all be the same size and all space on each will be unal- located. If not, some of the space will be wasted when you create the volume. Striped volumes increase both read and write performance when accessing the volume by uti- lizing all the disks at one time. Unlike spanned volumes, striped volumes cannot be extended. Striped volumes can be created using two to 32 disks. Use stripped volumes in the following situations: ■ The primary disk operation will be reading information from a large database such as SQL or Exchange. ■ The volume will be used to spool large print jobs. ■ You are not concerned with fault tolerance. ■ You plan to collect external data on the disk at very fast transfer rates.

When you write information to the mirror, it is written twice – once to each disk.This provides complete redun- dancy for your data. Should one disk fail, you can use the mirrored copy. Mirrored volumes provide only 50 percent disk utilization (the least cost efficient of all volume types) and cannot be extended. However, they provide excellent fault tolerance. Use mirrored volumes in the following situations: ■ You want to provide fault tolerance for the boot and/or system partition. ■ You want an easy way to roll back failed operating system upgrades (break the mirror before the upgrade). ■ You need fault tolerance, but you only have two disks. ■ You want to be able to get the system up and running quickly after a disk failure. 144 Chapter 5 • Managing Physical and Logical Disks Figure 5.58 Formatting the New Striped Volume Figure 5.59 Ending the New Volume Wizard 301_BD_W2k3_05.qxd 5/12/04 12:32 PM Page 144 Creating a mirrored volume 1.
