The entire goal of a SAN is to provide storage to hosts. Some low end SANs only support Intel-based servers running Windows NT,Windows 2000, or NetWare.  Better SANs can support hosts running WindowsNT, Windows 2000, NetWare, Linux, AIX, HP-UX, Solaris, and IRIX.\n\nHost Bus Adapters\n\nA host bus adapter (HBA) connects a server system to an external Fibre Channel storage system or to a Fibre Channel switch. In order to get the host operating system to recognize the HBA, a HBA driver must be installed.\n\n\n

看你的签名好有个性啊！\n现在在做存储吗？

Cables\n\nFibre Channel cables come in three basic varieties: copper, short wave fiber optic, and long wave fiber optic. Performance is the same for copper and optic cabling, however,greater distance can be achieved with optic cabling.\n\n光纤，不用我贴了吧？\n

Connectors\nCopper cables can use either a DB-9 connector or a high-speed serial data connector\n(HSSDC). Optical connections use SC connectors.

Media Interface Adapters\nA media interface adapter can be used to convert a copper connection into an optical connection. \n不是太常用的东西

To:老农，俺现在是做和存储相关的工作。打下手。\n\nExtenders\nExtenders such as an Optilinx 2000 can be used to increase the distances that a SAN canextend. In a SAN, extenders can be used to extend the distance between\ntwo storage implementing remote a remote mirror to 60KM.\n\n当互联的距离过远的时候用这个玩意儿

Switches, Hubs, and Directors\nSwitches, hubs, and directors are used to interconnect devices in a SAN fabric. Switches provide 100MB/s unblocked throughput on each port as opposed to hubs that provide 100MB/s shared bandwidth. Directors typically have the ability to connect Fibre Channel as well as other technologies such as ESCON.\n\n光纤通道交换机

Gigabit Interface Connectors\nGigabit interface connectors (GBIC) are hot-swappable devices that provide switches with the flexibility of changing a ports connection type from optical to copper.\n\n简称GBIC

嗯！很不错的贴子呀！！：）

A DPE includesa storage processor that is responsible for host communication and implementing RAID functions. DAEs can add storage capacity by connecting to DPEs.\n\nDPE是Storage的核心部分，这里重点说一下，DPE其实可以看作是一个微缩的计算机，有自己的CPU，内存和操作系统，加上Raid控制器，我们在存储设备上设置Raid，就是通过DPE上的Raid控制器完成的。DAE是用来扩充Storage容量的设备，本身一般都不具备Raid功能。
