想请教一下cache池的负载均衡设置


Recommended Posts

我用一个1T的nvme致钛TiPlus5000建了一个fast池,用来存储appdata、domains、isos、system,cache池用来作为下载、appdata备份以及阵列的中转使用。

我有两个SATA固态,分别是1T和2T,暂时没啥别的需求,就用来作为cache了,想请教一下cache的负载均衡选项都是什么意思。

现在是默认状态,似乎是把磁盘分成多块然后组成的双重备份,这种状态下对性能有什么影响?对数据的保护能力如何?我之前尝试过在这种状态下移除一个cache里的硬盘,启动阵列后unraid无法读取cache。

另外,转换为单一模式和raid0有什么区别?单一模式下好像还是从两块硬盘同时读写
