In this paper, we propose a static cache management policy for RAID architecture which uses an SSD as a disk cache. Because SSD has several drawbacks, dynamic cache management scheme such as LRU can cause serious problem i.e., too much write operations can be occurred in order to contain most recently used data. Frequent write operations on SSD not only slow down the performance but also shorten the...
Flash memory solid state disk (SSD) is gaining popularity and replacing hard disk drive (HDD) in mobile computing systems such as ultra mobile PCs (UMPCs) and notebook PCs because of lower power consumption, faster random access, and higher shock resistance. One of the key challenges in designing a high-performance flash memory SSD is an efficient handling of small random writes to non-volatile data...
