ODX的机制是将主机任务下发到存储阵列,在存储阵列内进行数据的拷贝且不需要经过主机,缓解了主机的I/O压力。 如果使用ODX,在Windows主机侧格式化盘时,建议allocation unit size选择64K,这样ODX会以64K作为IO的最小size,充分发挥ODX的性能。收藏 下载文档 更新时间:2024-10-17 文档编号:EDOC1100354516 浏览量:3396 ...
Allocation Unit Size也就是硬盘分区簇的大小。计算机的硬盘存储组织是以簇为单位的，假设文件大小为4097 Bytes，如果簇的大小为4096 Bytes，则文件需要两个簇进行存放，也就是文件实际占用空间为8192 Bytes；如果簇的大小为512 Bytes，则需要9个簇进行存放，实际占用空间为4608 Bytes。这说明簇越小越节省...

You may also want to know whether you should use different sizes for SSDs or hard drives. As mentioned above, fragmentation does not cause the same problems on solid-state drives as hard drives. Therefore, in theory, you can use a larger allocation unit size without affecting performance. Bu...

When you create a disk group, you can set the Oracle ASM allocation unit size with the AU_SIZE disk group attribute. The values can be 1, 2, 4, 8, 16, 32, or 64 MB, depending on the specific disk group compatibility level. Larger AU sizes typically ...
Cluster Read/Write has to be at unit of cluster allocation size. But the read/write at volume will happen at stripe size. So in that case allocation size should be in multiples of stripe size. Which implies that allocation size should be greater than stripe size for better performance....
在ASM中,可以通过调整_asm_ausize隐含参数的大小来进行调整,_asm_stripesize控制相应的条带化参数。 从v$asm_diskgroup视图可以查询得到相关的信息: SQL> select group_number,name,sector_size,block_size,allocation_unit_size from v$asm_diskgroup;
