When working with Windows, you have to work with disks. Although simple servers have you install Windows Server 2008 on a local IDE (parallel and serial) or SCSI hard drive, more complex systems may use an attached remote computer storage device such as a storage area network (SAN) or network-attached storage (NAS). Therefore, you need to know what options are available and how to configure a server’s physical and virtual disk drives so that the server can meet the needs of network applications while providing reliability.
The Virtual Disk Specification (VDS) protocol provides a mechanism for remote configuration of disks, partitions, volumes, and iSCSI initiators on a server. Through the VDS protocol, a client can change the configuration of disks into partitions, partitions into volumes, and volumes into file systems. In the VDS protocol, two entities are involved: the server whose storage is configured and the client who needs to change the server storage configuration.
IDE and SCSI Drives
Today’s hard drives are either integrated drive electronics (IDE) or small computer system interface (SCSI, pronounced “skuzzy”) drives. IDE drives are designed as fast, low-cost drives. Traditional IDE drives were based on the parallel AT attachment (ATA) standard that used a parallel 40-pin connector. Today’s IDE drives follow the serial ATA standard (SATA), which uses a connector that is attached with only four wires and a smaller power connector. Although the serial ATA uses fewer wires/connectors, it provides faster throughput then parallel ATA IDE drives.
Servers and high-performance workstations typically use SCSI drives. SCSI drives typically offer faster performance and throughput than IDE drives and SCSI drives support a larger number of drives to be attached through the same interface.
