A modern CPU (microprocessor) executes (at least) one instruction per clock cycle. Each different type of CPU architecture has its unique set of instructions, called itsinstruction set architecture(ISA). The instruction set architecture of a computer can be thought of the language that the compute...
such as a CD-ROM. The physical structure of a magnetic disk consists of concentric rings, called cylinders, and angular segments, called sectors, as shown inFigure 9-1. In addition, hard drives may consist of multiple platters (more than one physical disk in the drive...
A second data structure in the data buffer indicates which of the data sectors contain defects not accounted for by track formats. A disk controller uses a combination of information from the first and second data structures to identify logical data sectors requested for a data transfer....
Details and an example is given in Table 8.1: If the Basic Disk being converted contains partitions, then the structure of the Basic Disk will be preserved. Converted disks will be limited to the structure, given in Table 8.2. These partitions are needed in cases such as the boot loader, ...
The Logical Volume Manager does this by using a layer of device driver code that runs above the traditional physical device drivers. This logical view of the disk storage is provided to applications and is independent of the underlying physical disk structure. Figure 1 illustrates the layout of ...
One of the things that I appreciate about LVM is the logical command structure. The majority of the management commands are related and therefore relatively easy to remember. The point of the following table isnotto summarize the commands, but rather for you to notice that the commands are all...

ClickHouse As a database based on the OLAP scenario, it is natural to support the cluster. What we usually call ClickHouse cluster, refers to the p...
scale capacity up or down as users' storage needs change by simply adding or removing extents from an LV. The processes for both increasing and decreasing capacity are logical and simple. Since LVM provides a logical command structure, the commands are easy to remember and therefore user-...
