The numbers of algorithms are proposed to schedule real time transactions in order to produce the overall performance. This paper presents the overview of existing approaches for scheduling the real- time transactions. Earliest Deadline First (EDF) is a basic algorithm which meets th...

One of the key functions of the AMF is the implementation of RAID (see next section) or other optimization algorithm aimed at improving request speed to storage. • To assist the controller in certain AMF operations, there is a memory area. The goal of this memory area, called the “...
The anticipatory disk scheduling method proposed in (Iyer and Druschel, 2001) defers the processing of a new request, until it is ascertained that there are no further pending requests in the area of disk at which the R/W head resides. The improvement in performance due to this method is...
In Windows XP, any file that is split into more than one piece is considered fragmented. Not so in Windows Vista if the fragments are large enough – the defragmentation algorithm was changed (from Windows XP) to ignore pieces of a file that are larger than 64MB. As a result...
1. Bad Sector Repair:The primary function of HDD Regenerator is to repair bad sectors on a hard drive. It employs a unique algorithm to regenerate bad sectors, in many instances without affecting the data stored in them. 2. Non-destructive Repair:One of HDD Regenerator's standout features ...
if this time is above 100ms, qBitTorrent should stop downloading more or just keep that in memory, in order to perform larger sequential write with less I/O requests in its own queue, and allow better scheduling on the host system, while also keeping good response time for the rest of ...
in [6, 8]. For string of blocks ,each with its associated disk the SPIFFI video-server, [3]proposed a real-time access time (IO End- IO Start),and deadline priority-based disk scheduling algorithm that , the latest time at which the block can com-partitions requests into priority ...
Many people clone hard disks just to back up data for security reasons as it enables to successfully transfer all on-disk information including standard bootstrap code and other system service structures, thus maintaining the operating system's working capability. In case of a system malfunction, ...
In the following example, we will configure a mirrored disk of the first disk drive which contains our OS installation. To create the mirrored volume, perform the following: 1. Log on to the server and open Server Manager, and then expand Disk Management. 2. Locate the newly inserted disk...
