Disk Reads with DRAM Latency
نویسندگان
چکیده
The gap between the access time of primary and secondary storage technologies, often called the access gap, has long constrained the performance of computer systems. Unfortunately, this gap is growing, not shrinking. While today’s technologies improve the capacity of both of these storage media at a furious pace, they are not as successful at reducing access times. Instead, the speed of computations using only primary memory is increasing five to ten times faster than is the speed with which blocks on magnetic disk can be accessed [Katz89, Patterson88].

Solid-State Disk with Double Data Rate DRAM Interface for High-Performance PCs
We propose a Solid-State Disk (SSD) with a Double Data Rate (DDR) DRAM interface for high-performance PCs. Traditional SSDs simply inherit the interface protocol of Hard Disk Drives (HDD) such as Parallel Advanced Technology Attachment (PATA) or Serial-ATA (SATA) for maintaining the compatibility. However, SSD itself provides much higher performance than HDD, hence the interface also needs to b...
متن کاملFlash on Rails: Consistent Flash Performance through Redundancy
Modern applications and virtualization require fast and predictable storage. Hard-drives have low and unpredictable performance, while keeping everything in DRAM is still prohibitively expensive or unnecessary in many cases. Solid-state drives offer a balance between performance and cost and are becoming increasingly popular in storage systems, playing the role of large caches and permanent sto...

x latency DTC in two cycles. In contrast, state-of-the-art DRAM cache always reads the tags from DRAM cache that incurs high tag lookup latencies of up to 41 cycles. In summary, high DRAM cache hit latencies, increased inter-core interference, increased inter-core cache eviction, and the large application footprint of complex applications necessitates efficient policies in order to satisfy the ...

متن کاملAccess Latency Reduction in Contemporary DRAM Memories
Performances of DRAM memories are characterized by memory latency and bandwidth. Contemporary DRAM memories more successfully satisfy demands for higher bandwidth than lower latency. In this paper solutions, which may reduce latency of these memories, are investigated. These solutions are two new controller policies called ’Write-miss Only Close-Page’ and ’Write-miss Only Close-Page-Open previo...
