For partitions created by Windows 2000 and Windows Server 2003, the default starting sector for disks that have more than 63 sectors per track is the 64th sector. Microsoft provides a tool, DiskPar, which allows aligning the disk tracks with sector tracks. Simple, right? Well, it gets more complicated than this, but we’ll discuss that later. Reading from 2 tracks implies a realignment of the reading heads, thus it takes longer than reading a single track. In this way, the drive heads can reach the entire surface of each platter. As the platters spin, the drive heads move in toward the center surface and out toward the edge. The disk itself can’t handle smaller amounts of data than one sector.Įlectromagnetic read/write heads are positioned above and below each platter. A sector is the smallest physical storage unit on a disk and typically it will hold 512 bytes of data. Sections within each track are called sectors.
The data is stored on concentric circles on the surfaces known as tracks. Hard disks are organized as a concentric stack of platters. Realigning the hard disk is one of these things, which can lead to a significant performance improvement. Of course there’s always some tweaking you can do, preferably before going live with the system. The key to a system without problems is proper planning and design.
This is so true! As memory chips become cheaper and consolidation dictates more users per server, the disk subsystem turns into the main cause of performance problems. “ Disk subsystem bottlenecks cause more performance problems than server-side CPU or RAM deficiencies, and a poorly designed disk subsystem can leave your organization vulnerable to hardware malfunctions.“ If you’re planning an Exchange infra-structure or even if you have already implemented it, one of the must-reads is undoubtably Optimizing Storage for Exchange Server 2003.
