所有IBM 服务器硬盘的默认写缓存(Write-Cache)模式是直写Write-Through (WT)。 设置成直写Write-Through (WT)模式对于IBM服务器支持的硬盘控制器上的所有IBM硬盘来说是最好的。 在更改硬盘的写缓存(Write-Cache)模式前,连接在ServeRAID阵列卡上的硬盘必须是"Ready" 状态。"Ready" 状态说明硬盘还没有被添加到...
The STORAGE_WRITE_CACHE_PROPERTY structure is used with the IOCTL_STORAGE_QUERY_PROPERTY request to retrieve information about a device's write cache property.
Note: When running WriteCache with the Kernelfree loader, a Syslinux bootloader is left on the target machine to enable future OS deployment. In case you transfer the hardware, you should comply with the GPL license. You can also use the DeleteCache built-in action to remove the Syslinux bo...
1.write through:CPU向cache写入数据时,同时向memory(后端存储)也写一份,使cache 和memory的数据保持一致。优点是简单,缺点是每次都要访问memory, 速度比较慢。 2. post write:CPU更新cache数据时,把更新的数据写入到一个更新缓冲器,在合适的 时候才对memory(后端存储)进行更新。这样可以提高cache访问速度, ...
在x86 架构的 Cache 光谱线上,有 read 和 write 都 cache 的 Writeback 模式(简称 WB),有 read 时 cache,write hit 时同步写入 cache line 和 main memory,而 write miss 时不分配 cache line(即没有 write allocate),直接写入 memory 的 Writethrough 模式(简称 WT)。 图-1 而上图绿框的这个代表 Wri...
The controller card supports cache data read/write to improve the data read/write performance. It supports the following read/write policies: Read: The controller card uses the read policy Read Ahead. The controller card caches the data that comes after the data being read so that the cached ...
