单机OLAP Kafka不同磁盘组合方式性能测试。麻烦支持
* 服务器至少24块HDD硬盘7200rpm Cahce {color:#172b4d}256MB+ {color}
* 安装系统Centos 7.9 基于RAID卡搭建不同的HDD组合方式具体列表OLAP提供。[~qidaijie] **yinfutao** commented on *2023-02-15T15:42:10.103+0800*:
根据要求现使用8块HDD硬盘进行测试测试服务器2块480G SSD硬盘做raid1安装centos7.9系统8块8T HDD硬盘做raid5格式化后挂载/data目录关闭atime系统优化配置时钟同步

研发要求把服务器41.30上拆2块8T硬盘插到服务器41.29上做12块8T硬盘的raid5服务器41.30上5块8T硬盘做raid5和3块8T硬盘做raid5
raid5已完成

经过测试后续安装RAID时推荐以下配置
* 文件系统选择 {*}XFS{*}。
* 当硬盘总数大于 *8* 块时不建议选择RAID5可以使用RAID10。
** RAID10会损失一半的存储空间若是作为存储服务器则需要评估数据存储周期进行选择。
* RAID安装时推荐配置如下
** Strip Size1MB 带宽设置为1m
** Read Policy: RA读取机制设置为预读
** I/O Policy: CachedIO机制设置为缓存IO
** Write Policy: WB写入策略回写
** 其他默认。
