摘要:The ever-growing amount of data requires highly scalable storage solutions. The most flexible approach is to use storage pools that can be expanded and scaled down by adding or removing storage devices. To make this approach usable, it is necessary to provide a solution to locate...

摘要:The availability of high-speed solid-state storage has introduced a new tier into the storage hierarchy. Low-latency and high-IOPS solid-state drives (SSDs) cache data in front of high-capacity disks. However, most existing SSDs are designed to be a drop-in disk replacement, and ...

摘要:Due to the large access latency of hard disks during data retrieval in computer systems, buffer caching mechanisms have been studied extensively in database and operating systems. By storing requested data into the buffer cache, subsequent requests can be directly serviced withou...

摘要:In this article, we present LWDLS, a lightweight data location service designed for Exascale storage systems (storage systems with order of 1018 bytes) and geo-distributed storage systems (large storage systems with physically distributed locations). LWDLS provides a s...

摘要:Storage area network (SAN) is one of the most popular solutions for constructing server environments these days. In these kinds of server environments, HDD-based storage usually becomes the bottleneck of the overall system, but it is not enough to merely replace the devices with ...

摘要:We introduce a new closed-form equation for estimating the number of data-loss events for a redundant array of inexpensive disks in a RAID-6 configuration. The equation expresses operational failures, their restorations, latent (sector) defects, and disk media scrubbing by time-b...

摘要:Solid-state drives (SSDs) update data by writing a new copy, rather than overwriting old data, causing prior copies of the same data to be invalidated . These writes are performed in units of pages , while space is reclaimed in units of multipage erase blocks , necessitating...

摘要:Byte-addressable non-volatile memory (NVM) is going to reshape conventional computer systems. With advantages of low latency, byte-addressability, and non-volatility, NVM can be directly put on the memory bus to replace DRAM. As a result, both system and application softwares hav...

摘要:Emerging non-volatile memory (NVM) offers non-volatility, byte-addressability, and fast access at the same time. It is suggested that programs should access NVM directly through CPU load and store instructions. To guarantee crash consistency, durable transactions are regarde...

摘要:Although the multilevel cell (MLC) technique is widely adopted by flash-memory vendors to boost the chip density and lower the cost, it results in serious performance and reliability problems. Different from past work, a new cell programming method is proposed to not only signifi...
