Sample text

The major performance issue for disk drives is usually application-related; that is, whether large numbers of small accesses will be made (random), or smaller numbers of large accesses (sequential). For random access, performance will generally be better using larger numbers of smaller capacity drives. The opposite situation exists for sequential access (use faster drives or use striping with larger number of drives). Physical disk buffers The Logical Volume Manager (LVM) uses a construct called a pbuf to control a pending disk I/O.

A process can either ignore the signal or it can release memory pages using the disclaim() subroutine. npskill The operating system will begin killing processes when the amount of paging space left on the system goes below this threshold. When the npskill threshold is reached, the operating system sends a SIGKILL signal to the youngest process. Processes that are handling a SIGDANGER signal and processes that are using the EPSA policy are exempt from being killed. nokilluid By setting the value of the nokilluid value to 1 (one), the root processes will be exempt from being killed when the npskill threshold is reached.

If the primary is busy, the system checks the secondary. If it is not busy, the read is initiated on the secondary. If the secondary is busy, the read is initiated on the copy with the least number of outstanding I/Os. Writes are initiated concurrently. Parallel/sequential The parallel/sequential policy always initiates reads on the primary copy. Writes are initiated concurrently. Parallel/round robin The parallel/round robin policy is similar to the parallel policy except that instead of always checking the primary copy first, it alternates between the copies.
