View PDF. Scenarios This section uses Windows Server R2 Enterprise 64bit to describe how to initialize a data disk attached to a server running Windows. Prerequisites A data disk has been attached to a server and has not been initialized. You have logged in to the server. Procedure On the desktop of the server , right-click Computer and choose Manage from the shortcut menu. The Disk Management window is displayed.
If Figure 1 is displayed, the new disk is offline. Go to 3. If Figure 4 is displayed, the Initialize Disk window is prompted. Go to 5. Figure 1 Server Manager Windows Server When the Disk 1 status changes from Offline to Not Initialized , the disk has been brought online. Figure 2 Bring online succeeded Windows Server The Initialize Disk dialog box is displayed. Figure 3 Initialize Disk Windows Server Figure 4 Server Manager Windows Server The New Simple Volume Wizard window is displayed.
The Specify Volume Size page is displayed. The Assign Drive Letter or Path page is displayed. Figure 8 Format Partition Windows Server Wait for the initialization to complete. When the volume status changes to Healthy , the initialization has finished successfully, as shown in Figure Figure 10 Disk initialization succeeded Windows Server If New Volume D: appears, the disk is successfully initialized and no further action is required.
A spanned volume is formatted like a single drive and can have a drive letter assigned to it, but it will span multiple physical drives. A spanned volume—occasionally referred to as an extended volume —provides no fault tolerance and increases your exposure to failure, but does permit you to make more efficient use of the available hard disk space. Striped volume Like a spanned volume, a striped volume combines multiple hard disk portions into a single entity. A striped volume uses special formatting to write to each of the portions equally in a stripe to increase performance.
A striped volume provides no fault tolerance and actually increases your exposure to failure, but it is faster than either a spanned volume or a single drive. A stripe set is often referred to as RAID-0 , although this is a misnomer because plain striping includes no redundancy.
Mirror volume A pair of dynamic volumes that contain identical data and appear to the world as a single entity. Disk mirroring can use two drives on the same hard disk controller or use separate controllers, in which case it is sometimes referred to as duplexing.
In case of failure on the part of either drive, the other hard disk can be split off so that it continues to provide complete access to the data stored on the drive, providing a high degree of fault tolerance. This technique is called RAID RAID-5 volume Like a striped volume, a RAID-5 volume combines portions of multiple hard disks into a single entity with data written across all portions equally.
However, it also writes parity information for each stripe onto a different portion, providing the ability to recover in the case of a single drive failure. A RAID-5 volume provides excellent throughput for read operations, but it is substantially slower than all other available options for write operations. Rather than using several inexpensive hard disks and providing fault tolerance through redundancy, you buy the best hard disk you can and bet your entire network on it.
JBOD Just a bunch of disks. The hardware equivalent of a spanned volume, this has all the failings of any spanning scheme. The failure of any one disk will result in catastrophic data failure.
Over time, SCSI became the only real choice for the vast majority of servers and even became mainstream on high-end workstations. Servers at the high end might use fiber, but SCSI had the vast majority of the server disk market.
SCSI has changed over the years to support faster speeds, more disks, and greater ease of configuration and use, but is finally reaching its limits as a parallel interface.
