磁盘阵列的微码是什么？是操作系统？\r\n谁能帮忙介绍一下

磁盘阵列一词的定义，根据SNIA（存储网络国际协会）的定义解释，磁盘阵列（disk array）就是通过一套控制软件结合在一起的、在一个或多个可访问磁盘子系统上的一系列磁盘；该控制软件将这些磁盘的存储空间以一个或多个虚拟磁盘的形式提供给主机；运行在控制器上的控制软件一般称为固件（firmware）或微码（microcode）；运行在主机上的通常称为卷管理器。而磁盘阵列子系统（disk array subsystem）才是我们通常所称的磁盘阵列，即具有可将其磁盘组织起来的控制软件的磁盘子系统。

1: What is Microcode, this is a example from EMC. Symmetrix Enginuity(microcode) is the operating environment for the\r\nSymmetrix DMX series. Enginuity manages and ensures the optimal\r\nflow and integrity of information through the different hardware\r\ncomponents of the Symmetrix system.\r\n\r\n2: What\'s the function of Microcode? Enginuity(Microcode)manages all Symmetrix operations, including monitoring\r\nand optimizing internal data flow, ensuring the fastest response to\r\nthe user\'s requests for information, and protecting and replicating\r\ndata.\r\nEnginuity provides the following services for the Symmetrix DMX\r\nseries:\r\n◆ Manages system resources to intelligently optimize performance\r\nacross a wide range of I/O requirements.\r\n◆ Ensures system availability through advanced fault monitoring,\r\ndetection, and correction capabilities. Enginuity also provides\r\nconcurrent maintenance and serviceability features.\r\n◆ Interrupts and prioritizes tasks from microprocessors and, for\r\nexample, ensures that fencing off failed areas takes precedence\r\nover other operations.\r\n◆ Offers the foundation for specific software features available\r\nthrough EMC’s disaster recovery, business continuance, and\r\nstorage management software.\r\n◆ Provides functional services for both its host Symmetrix series\r\nand for a large suite of EMC storage application software.\r\n◆ Defines the priority of each task, including basic system\r\nmaintenance, I/O processing, application processing (for\r\nexample, EMC® ControlCenter™, SRDF®, TimeFinder®, and EMC\r\nControlCenter Symmetrix Optimizer).\r\n◆ Provides uniform access through APIs for internal calls and\r\nprovides an external interface to allow integration with other\r\nsoftware providers and independent software vendors.

\r\n从提供的功能来看，和操作系统类似，那我是不是可以认为就是操作系统？

我同意你的看法，其实就是磁盘阵列的操作系统，只是不同的厂家有不同的叫法。
