RETHINKING FLASH IN THE DATA CENTER 反思闪存在数据中心——寿浙威 非师 1271408006DEPLOYMENT OF FLASH MEMORY DEPENDS ON MAKING THE MOST OF ITS UNIQUE PROPERTIES INSTEAD OF TREATING IT AS A DROP-IN REPLACEMENT FOR EXISTING TECHNOLOGIES.闪存的未来应用取决于能否充分利用它的特性，而不要把它对待成为一个突然闯入并且来替代现有技术的。Over the past few years, computer systems of all types have started integrating flash memory. Initially, flash’s small size, low power consumption, and physical durability made it a natural fit for mediaplayers and embedded devices. Lately, flash’s rising density has won it a place in laptops and some desktop machines. 再过去的几年中，各种类型的计算机系统开始集成闪存。一开始，闪存体积小、低功耗以及物理上的持久特性使得它能很好的适合那些媒体播放器、嵌入设备。最近，闪存的高密度集成使它在笔记本电脑和台式电脑上也赢得了一些地位。Flash is now poised to make deep inroads into the data center. There, flash memory’s high density, low power, and low-cost I/Os per second will drive its adoption and enable its application far beyond simple hard drive replacements. To date, however, many uses of flash have been hamstrung by a fundamental challenge of the technology: Flash is neither magnetic disk nor DRAM. It has its own performance advantages and quirks that system designers must address at several levels to best exploit it. 现在，闪存已经很自然的进入了数据中心。那些，闪存的高密度、低功耗和输入输出率的低消耗使得它的被采纳度和应用远远超越了简单的对硬盘驱动器的替代。然而，对于数据来说，大量对闪存的使用已经遭到了基础技术的质疑和阻碍：闪存既不是磁盘，也不是动态随机存取存储器。闪存拥有它自身的优点和怪癖，为了更好的利用它，系统设计师必须对它多重编址。Disk and DRAM replacement 代替磁盘和动态随机存取存储器So far, most proposed applications for flash in the data center have fallen into two categories.目前，很多对闪存在数据中心提出的应用可以分为两类。The first category is disk replacement. Quick access time and low power requirements make flash a compelling replacement for conventional disks, albeit at much lower density and higher cost. Accounting for servers and supporting infrastructure, solid-state disks (SSDs) consume roughly 10 times less energy when idle than disks. They deliver 2.6 times more bandwidth per watt and 3.2 times more bandwidth per dollar, 25 times more I/O operations per second (IOPS) per dollar, and 2,000 times more IOPS per watt .第一类就是代替磁盘。快速读取和小功率的要求使得闪存替代密度既低，消耗又高的传统磁盘引人注目，对于服务器的解释和基础设备的支持上，固态硬盘(SSDs)在系统闲置时的消耗时间大约是磁盘的十分之一，它们能传输2.6倍更多的带宽每瓦特，3.2倍更多的带宽每美元，25倍更多的输入输出操作每秒(IOPS)每美元、2000倍更多IOPS每瓦特。Flash sometimes also serves as a DRAM replacement. Density and (again) energy efficiency let flash compete with DRAM in applications where latency and bandwidth are less important. Flash consumes one-fourth the power of DRAM per byte at one-fifth the price.闪存有时候也充当动态随机存取存储器的作用。密度和能量效能使闪存能够在那些潜在因素和带宽不是很重要的应用领域中和DRAM竞争，因为闪存仅仅是DRAM每字节消耗的四分之一，同时价格是DRAM的五分之一。Flash memory will remain a contender for both roles for the foreseeable future, but additional opportunities and challenges are on the horizon. Technology scaling will continue to increase bit density for another 1 to 2 process generations, which will drive down costs. However, smaller flash cells are less reliable and less durable.
