| 摘 要： | 为了发挥iSCSI存储系统不受距离限制、大容量、易扩充和传输性能较高等特点,减少直接对磁盘阵列进行操作的次数,以便提高系统的数据传输速率,提出了一种高效的iSCSI缓存机制.通过加载该缓存模块,可以有效减少直接访问磁盘阵列的次数,加快系统响应速度,提高了iSCSI系统的性能.最后用网络仿真软件NS-2进行测试,测试结果表明了该方法的可行性.

| Abstract: | To use those advantages of iSCSI storage system,such as it hasn'tdistance limitations,huge capacity,easy expansibility and better transfers performance,reduce operations directly on the storage devices in order to improve the transfer speed,a high performance buffer mechanism is proposed.This mechanism avoided operating directly on the storage devices.By using the high performance buffer mechanism,the iSCSI system has shorter the number of operating directly on the storage devices,faster the response time a... |
