Description
Technical field
The invention belongs to hard disk processing technical field, relate in particular to a kind of implementation method and device of hybrid hard disk.
Background technology
In hybrid hard disk product, generally there are two kinds of storage mediums: a kind of is traditional magnetic disk media (being also referred to as storage medium at a slow speed), and feature is that capacity is large, cheap, but access speed is slower; Another kind is quick storage medium, and as NAND FLASH, feature is that capacity is less, expensive, but access speed is very fast.Quick storage medium is commonly used to buffer memory hot spot data (reading and writing number of times data more frequently).
Can the performance of hybrid hard disk how, whether enough effectively depends primarily on cache management scheme, identify accurately hot spot data, possesses higher cache hit rate.Current, there is the cache management scheme of two kinds of main flows:
(1) by host operating system, directly control the quick storage medium in hybrid hard disk, complete the management of hot spot data buffer memory.Hybrid hard disk provides some newly-increased ata commands, allows host operating system to determine which hot spot data is left in the quick storage medium of hybrid hard disk, or delete some outdated data from the quick storage medium of hybrid hard disk.Due to host operating system, accurately know and self start required fileinfo, can in advance associated documents be left in quick storage medium, so this scheme is very effective to improving the toggle speed of operating system.
(2) by hybrid hard disk, controlled voluntarily the use of buffer memory.Now, hybrid hard disk externally shows as a common mechanical hard disk, but the read-write frequency of its inner meeting statistics copies the high hot spot data of read-write frequency in quick storage medium to.When user requires to read described hot spot data again, hybrid hard disk directly obtains described hot spot data from quick storage medium, thereby accelerates the access of hot spot data.This scheme does not need to rely on host operating system just can give play to the function of hybrid hard disk.
In above-mentioned two schemes, which hot spot data buffer memory, to quick storage medium, is determined by host operating system or hybrid hard disk.Yet host operating system or hybrid hard disk rely on statistical law to identify hot spot data, have certain blindness.When there is multi-level buffer, rely on merely statistical law to identify hot spot data, likely get the wrong sow by the ear.For example, A, two files of B in hybrid hard disk, have been preserved, wherein A file is often accessed by the user, therefore host operating system is left in the file cache of oneself, the access of user to A file like this, all by host operating system, tackled, directly from described file cache, read, do not need to send I/O request to hybrid hard disk; B file is seldom used by user, and therefore, not in the file cache of host operating system, the access of user to B file, need to send I/O request to hybrid hard disk.From the angle of hybrid hard disk, A file is cold data, and B file is hot spot data, just the opposite with actual conditions.
From description above, can find out, simple host operating system or the hybrid hard disk of relying on added up data access frequency, cannot accurately identify hot spot data, and then cannot effectively utilize the quick storage medium of hybrid hard disk, affect the I/O performance of hybrid hard disk.
