PCIe是什么？PCIe标准和PCIe布线规则总结概述

PCIe是什么？PCIe标准和PCIe布线规则总结概述PCI-Express(peripheral component interconnect express)是一种高速串行计算机扩展总线标准，它原来的名称为“3GIO”，是由英特尔在2001年提出的，旨在替代旧的PCI，PCI-X和AGP总线标准。

PCIe属于高速串行点对点双通道高带宽传输，所连接的设备分配独享通道带宽，不共享总线带宽，主要支持主动电源管理，错误报告，端对端的可靠性传输，热插拔以及服务质量(QOS)等功能。

PCIe交由PCI-SIG（PCI特殊兴趣组织）认证发布后才改名为“PCI-Express”，简称“PCI-E”。

它的主要优势就是数据传输速率高，目前最高的16X 2.0版本可达到10GB/s，而且还有相当大的发展潜力。

PCI Express也有多种规格，从PCI Express 1X到PCI Express 32X，能满足将来一定时间内出现的低速设备和高速设备的需求。

PCI-Express最新的接口是PCIe 3.0接口，其比特率为8GB/s，约为上一代产品带宽的两倍，并且包含发射器和接收器均衡、PLL改善以及时钟数据恢复等一系列重要的新功能，用以改善数据传输和数据保护性能。

INTEL、IBM、LSI、OCZ、三星(计划中)、SanDisk、STEC、SuperTalent和东芝(计划中)等，而针对海量的数据增长使得用户对规模更大、可扩展性更强的系统所应用，PCIe 3.0技术的加入最新的LSI MegaRAID控制器及HBA产品的出色性能，就可以实现更大的系统设计灵活性。

当然，主流主板都能能支持PCI Express 1.0 16X，也有部分较高端的主板支持PCI Express 2.016X。

PCIe标准PCI Express卡适合其物理尺寸或更大的插槽（使用×16作为最大的），但可能不适合更小的PCI Express插槽;例如，×16卡可能不适合×4或×8插槽。

PCIe3.0+USB3.0!Intel 7系芯片组解析

PCIe3.0+USB3.0!Intel 7系芯片组解析Intel今年发布的Sandy Bridge处理器虽然让人眼前一亮，但配套的6系列芯片组却相当不给力：LGA1155与LGA115接口完全不兼容、规格改进有限、芯片组磁盘控制器出现BUG、加之P67和H67定位模糊不清，整个6系列芯片组都让人比较失望。

好在2012年初Intel就会发布全新的7系列芯片组，新一代主流芯片组将会沿用LGA1155接口，与6系列保持完美兼容，但无论处理器还是芯片组规格都会有很大的改进。

Intel 7系芯片组，包括面向主流平台的第二代Sandy Bridge（Ivy Bridge）LGA 1155芯片组，以及面向发烧用户的X79芯片组，将采用全新LGA2011接口（支持四通道DDR3内存）。

新的工艺，新的架构以及一些新的技术值得我们期待，下面就让我们一起来分享这些即将或者将要推出的产品吧。

第2页：Z68芯片组：P67与H67的合体5月11日，Intel就将发布这款期待已久的芯片组，它采用了LGA 1155接口，支持现有的Sandy Bridge架构处理器。

Intel Z68芯片将和P67一样，拥有强大的超频能力，不过它同时也支持H67的显示输出功能，基本上我们可以把它看作是P67与H67的合体，用户就不需要再纠结于选H67还是P67的问题了，直接购买Z68即可，但价格当然要更高一些。

另外值得关注的还有Smart Response技术。

据悉Z68芯片推出时，一些主板厂商推出的主板都将捆绑Lucid V irtu软件，用户能够更具自己的需求动态切换显示模块，节能和性能两不误。

Intel Smart Response技术只在传统PC上添加一块SSD固态硬盘，让其作数据缓存只用，能够有效提高那些数据读取和写入速度，使得容量和速度得到了很好的平衡。

LSI公司推出LSI WarpDriveTM SLP

LSI 公司推出LSI WarpDriveTM SLP
日前，LSI 公司宣布推出LSI WarpDriveTM SLP-300 加速卡，这是一款采用PCI Express (PCIe) 标准针对应用加速的固态存储解决方案，现可搭配可选式Supermicro 服务器解决方案推出。

Supermicro 首席执行官兼总裁Charles Liang 指出：过去几年来，我们同LSI 的合作愈加密切，功能强大的突破性LSI WarpDrive 卡进一步丰富了我们广泛的服务器和存储解决方案产品系列。

WarpDrive 卡能够为我们的企业服务器客户提供简便高效的低成本应用加速功能，同时能够显着优化
数据中心的运行效率。

屡获殊荣的LSI WarpDrive SLP-300 加速卡性能高达240,000 的持续IOPS，具有小型化尺寸，支持300GB 的SLC 固态存储容量。

该解决方案旨在实现数据密集型应用和工作负载的事务处理I/O 性能最大化，满足Web 服务、数据仓库、数据挖掘、专业视频及高性能计算等应用需求。

低截面半长WarpDrive 卡能够插入Supermicro 服务器解决方案标准的8 信道PCIe Gen 2.0 插槽，以低时延和低CPU 负载实现高性能。

WarpDrive 卡无需存储支架即可提供数百个硬盘驱动器的I/O 性能，且功耗。

PCI-E NVMd

NVMe推动PCIe与闪存紧密结合当闪存时代到来，数据中心的存储会是以什么形式存在呢？磁盘时代毫无疑问，磁盘阵列是数据中心存储的主要组成部分，在磁盘阵列的组织下，大量磁盘可以并发工作，满足应用对存储性能的需求。

但是闪存不一样，闪存代表的是更简单、高效、高性能的存储。

要达到这个效果，接口和接口走的协议是非常重要的一环，SCSI/SAS的一套体系显然是无法充分发挥闪存性能的，可以预见的是PCIe/NVMe是闪存的未来。

本文也将围绕PCIe/NVMe来谈下闪存的未来。

针对磁盘可以说SAS是一个非常优良的接口，在其设计之初就将数据怎样写进磁盘进行了全面的考虑，通过HBA卡组织多块硬盘方便的组织在一起形成一个完整的存储池，另一方面SAS的接口带宽已经发展到了12Gb/s，而且当下随着光纤SAS技术的发展，其在存储阵列中的应用也越来越多，可以说SAS 是磁盘完美搭档。

但是SAS的体系架过于复杂，对于追求高性能而且可靠性比磁盘高的多的闪存来说SAS自然并不是一个好选择，这就催生了固态硬盘接口从SAS/SATA向PCIe的转换，但是出现的新问题是物理接口转换到PCIe之后，那么数据传输协议使用什么呢？LSI之前的做法是在PCIe闪存卡中加入一个SAS控制器进行转接，这种做法将闪存产品的形态快速的从固态硬盘转向了PCIe闪存卡，但是从根本上讲这依然是一个SAS固态硬盘。

PCIe闪存卡需要的是一个新的高效、简洁而且能发挥其高性能的协议标准，之前Fusion-io为代表的闪存初创公司也做出了努力，但是其标准并不开放，所以并没有受到广泛的重视，就在这样一个背景下NVMe就在这种背景下被设计出来，简单说来NVMe规范了PCIe闪存卡存储数据的协议标准，使得PCIe成为了更优秀的硬盘接口。

从上图可以直观的看出从应用到闪存盘的过程中，到NVMe驱动器的路径要比到SAS驱动器的路径短，简化的路径缩短了数据传输的中间环节。

NVMe 相对于SCSI/SAS的延迟上的降低是非常明显的。

PCI-E_3.0技术及发展一览剖析

PCI-E 3.0标准规范早在2007年上半年PCI-E 2.0版规范刚刚公布的时候，PCI Express技术标准组织PCI-SIG就准备用两年多的时间将其快速进化到第三代，但是谁也没想到PCI-E 3.0的酝酿过程会如此一波三折，直到3年半以后才最终修成正果。

PCI-SIG主席兼总裁几乎泪流满面：“PCI-SIG始终致力于I/O创新，我们也很骄傲地向我们的成员发布PCI-E 3.0规范。

PCI-E 3.0架构从细节上对前两代PCI-E规范进行了极大地改进，为我们的成员在各自领域继续创新提供了所必需的性能和功能。

”在对可制造性、成本、功耗、复杂性、兼容性等诸多方面进行综合、平衡之后，PCI-E 3.0规范将数据传输率提升到8GHz|8GT/s(最初也预想过10GHz)，并保持了对PCI-E 2.x/1.x的向下兼容，继续支持2.5GHz、5GHz信号机制。

基于此，PCI-E 3.0架构单信道(x1)单向带宽即可接近1GB/s，十六信道(x16)双向带宽更是可达32GB/s。

PCI-E 3.0同时还特别增加了128b/130b解码机制，可以确保几乎100%的传输效率，相比此前版本的8b/10b机制提升了25%，从而促成了传输带宽的翻番，延续了PCI-E规范的一贯传统。

新规范在信号和软件层的其他增强之处还有数据复用指示、原子操作、动态电源调整机制、延迟容许报告、宽松传输排序、基地址寄存器(BAR)大小调整、I/O 页面错误等等，从而全方位提升平台效率、软件模型弹性、架构伸缩性。

PCI-E 3.0规范完整文档现已向PCI-SIG组织成员公布其中详细描述了PCI-E架构、互联属性、结构管理、编程接口等等，但没有公开发表。

sections:•Section1.1,“Overview”•Section1.2,“Features”•Section1.3,“PCI Performance”•Section1.4,“Software”1.1OverviewThe LSI PCIe to SAS host bus adapters(HBAs)provide four or eightserial ports for connection to SAS/SATA(Serial ATA)devices.Each portis capable of a SAS link rate and a SAT A link rate of3.0-Gb/s.The PCIExpress transmission and reception data rate is2.5-Gb/s in eachdirection,yielding a total bandwidth of5.0-Gb/s for each full-duplex lane.The LSI PCIe to SAS HBAs are implemented using four or eight PCIExpress PHYs,which provide possible host-side maximum transmissionand reception rates of up to4.0-GB/s.The LSI PCIe to SAS HBAs contain Flash ROM for storing the BIOS andﬁrmware,and NVSRAM for storing nonvolatile RAID information.TheSAS3442E,SAS3442EL,SAS3444E,SAS3444EL,SAS3800E,SAS3801E,SAS3801EL and SAS31601E HBAs provide a128K x36-bPBSRAM memory device for storing SAS Address Port informationallowing for connection to more than128devices.The LEDs on theHBAs report a heartbeat,activity,and fault conditions when detected byﬁrmware.Fusion-MPT™ﬁrmware operates the HBA.The PCI Express interface is compliant with the PCI ExpressSpeciﬁcation,revision1.0a.All PCI software is backwards compliant withPCIe to3.0-Gb/s SAS Host Bus Adapters User’s Guide1-1Copyright©2006-2007by LSI Corporation.All rights reserved.previous versions of the PCI/PCI-X speciﬁcations.The LSI PCIe to SASproducts implement the PCI Express interface as a x4or x8interface.The LSI PCIe to SAS HBAs use either a standard PCI or a low-proﬁlePCI bracket type.The LSI PCIe to SAS Host bus adapter(HBA)SASinterface is compatible with the ANSI Serial Attached SCSI Speciﬁcation,revision1.0and the Serial AT A Speciﬁcation,revision1.0a.The functionality of LSI PCIe to SAS HBAs come from either theLSISAS1064E controller chip or the LSISAS1068E controller chip.TheLSISAS1064E integrates four high-performance SAS/SATA PHYs andthe LSISAS1068E integrates eight high-performance SAS/SATA PHYs.The design of LSI PCIe to SAS HBAs makes it easy to add SASinterfaces to any computer,workstation,or server with a PCI Expressbus.Table1.1shows the LSI PCIe to SAS controllers and their associatedHBAs that support SAS/SATA devices.All board numbers contain an“E”after the numeric portion of their name,indicating that they use the PCIExpress bus.Boards without an“L”after the numbers in their name usea standard PCI bracket type.Boards with an“L”after the numbers intheir name use a low-proﬁle PCI bracket type.Table1.1LSI PCIe to SAS HBAs and ControllersControllers LSI PCIe to SAS HBAsLSISAS1064E SAS3041E,SAS3041EL,SAS3042E,SAS3042ELLSISAS1068E

【摘要】PCle 的出现成就了PCI 总线的世代交替,并取代了AGP 8x 绘图卡接口。

从英特尔9xx 系列芯片组的进化已看出其企图。

虽然 PCle x16取代 AGP 8x 的任务在台式机和笔记本电脑上都能圆满达成,但在外围的应用上则尚未开花结果。
