Abstract: Fault isolation capabilities made available by user space can be provided for a embedded network storage system without sacrificing efficiency. By giving user space processes direct access to specific devices (e.g., network interface cards and storage adapters), processes in a user space can initiate Input/Output requests without issuing system calls (and entering kernel mode). The multiple user spaces processes can initiate requests serviced by a user space device driver by sharing a read-only address space that maps the entire physical memory one-to-one. In addition, a user space process can initiate communication with another user space process by use of transmit and receive queues similar to transmit and receiver queues used by hardware devices. And, a mechanism of ensuring that virtual addresses that work in one address space reference the same physical page in another address space is used.

Abstract translation: 可以为嵌入式网络存储系统提供用户空间提供的故障隔离功能，而不会牺牲效率。 通过给用户空间处理直接访问特定设备（例如，网络接口卡和存储适配器），用户空间中的进程可以发起输入/输出请求，而不发出系统调用（并进入内核模式）。 多个用户空间进程可以通过共享一个将整个物理存储器映射到一个的只读地址空间来发起由用户空间设备驱动程序服务的请求。 此外，用户空间进程可以通过使用类似于由硬件设备使用的发送和接收队列的发送和接收队列来发起与另一个用户空间进程的通信。 并且，使用一种确保在一个地址空间中工作的虚拟地址引用另一个地址空间中的同一物理页面的机制。
