Abstract
The disregarded performance of erase operation in low-latency NAND flash memory relatively increases the impact of garbage collection interferences, which is a challenge when considering the use for storage class memory applications. Conventional erase-related techniques do not sufficiently conceal the impact of erase operation and incur a performance trade-off between throughput and latency. In this paper, we propose a boost and stop erase (BOOSTER) technique consisting of a multi-block erase technique and an adaptive erase suspension technique. The proposed technique improves both throughput and latency of low-latency NAND flash-based SSDs. Our experiments show 1.15× higher throughput and 27.2% lower latency than the conventional techniques in the small random workload. The proposed technique also passes the certification test with 1.8 to 4.9× higher load in Aerospike Certification Tool evaluations.
低延迟NAND闪存中被忽视的擦除操作性能相对增加了垃圾收集干扰的影响,当考虑使用存储类内存应用程序时,这是一个挑战。传统的擦除相关技术不能充分隐藏擦除操作的影响,并导致吞吐量和延迟之间的性能权衡。本文提出了一种由多块擦除技术和自适应擦除悬浮技术组成的boost and stop erase (BOOSTER)技术。该技术提高了基于NAND闪存的低延迟ssd的吞吐量和延迟。我们的实验表明,在小的随机工作负载下,吞吐量比传统技术提高了1.15倍,延迟降低了27.2%。该技术还通过了Aerospike认证工具评估的认证测试,负载提高了1.8到4.9倍。
