对磁盘高速存取(提速): RAID将普通硬盘组成一个磁盘阵列，在主机写入数据，RAID控制器把主机要写入的数据分解为多个数据块，然后并行写入磁盘阵列；主机读取数据时，RAID控制器并行读取分散在磁盘阵列中各个硬盘上的数据，把它们重新组合后提供给主机。由于采用并行读写操作，从而提高了存储系统的存取系统的存取速度-High-speed disk access (speed): RAID will be common to form a hard drive disk array, the host

基于COW( Copy- o n-Write) 读写模式的虚拟块设备有利于实现大规模虚拟机环境下虚拟机的快速部署. 文中为虚拟机管理器中的COW 虚拟块设备设计了一种优化方法, 能够提高COW 磁盘的访问性能以及生成多个 小尺寸的COW 磁盘映像文件, 以降低通过网络部署虚拟机的开销.-Design an optimized method for Virtual Machine Manager COW virtual block device conducive to the reali

When a limited amount of bandwidth is allocated for communication services, a system is required to accommodate as many users as possible by effectively sharing the limited bandwidth. Therefore, in the field of communications, the term multiple acces

We consider a multicell multiple-input-multipleoutput (MIMO) orthogonal-frequency-division-multiple-access (OFDMA) scenario conforming to the 3GPP Long Term Evolution (LTE) recommendation. Scheduling policies proposed for interference mitigation in L
