Raid 配置的规划
安装 TiDB 集群的物理机配置如下：
用 14 * 1.92TB SATA SSD 组成 RAID10 后，减去 RAID 的元数据和 1024 的转换损失，实际共 12819716 MB 可用。因为所有的节点都配置了 SSD 磁盘，且数据规模较大，所以需要配置成 TiDB 和 TiKV 的混合部署模式。
目前我们共配置 80 VCPU 的主机，按 16 个 VCPU 一个组件，大概可以配置 5 个组件，每台物理主机共部署 4 个 TiKV 和 1 个 TiDB。按一个 TiKV 约 2 TB 的容量规划，配置一个 3 TB 的空间，保证空间占用在 80% 以下。所以 12819716 MB 的容量空间分成 4 个 3 TB 的空间，挂接在 /data{0123}，和 1 个 500 GB 的空间，挂接在 /deploy。
混合部署的 CPU 和内存配置，可以参考文档 https://docs.pingcap.com/zh/tidb/dev/hybrid-deployment-topology 。
在操作系统中可以使用 RAID 卡的命令行管理工具，实现在线的 RAID 重配置，免去了重启和控制台访问等问题。
目前 x86 服务器中，主要使用 Microchip 的 SmartROC 系列（收购 adaptec 公司后发布的产品）和 Broadcom 的 Megaraid 系列（收购 avago 公司后发布的产品)，以下以这两款 RAID 卡配置为例。

RAID 卡背景信息
使用操作系统命令查看 RAID 卡型号是 ZTE 中兴服务器 R5300 G4 的 RAID 卡 SDPSA_L-18i
[host bin]$ sudo dmidecode |grep -i "product name" Product Name: R5300 G4 Product Name: R5300G4[host bin]$ sudo dmidecode |grep -i RAID[host bin]$ sudo lspci |grep -i RAID[host bin]$ sudo dmesg |grep -i RAID[ 6.360527] smartpqi 0000:3c:00.0: added 14:1:0:0 4000000000000000 Direct-Access ZTE LOGICAL VOLUME SSDSmartPathCap- En- RAID-1(1+0) [ 6.386016] smartpqi 0000:3c:00.0: added 14:1:0:1 4000000100000000 Direct-Access ZTE LOGICAL VOLUME SSDSmartPathCap- En- RAID-1(1+0) [ 6.396947] smartpqi 0000:3c:00.0: added 14:2:0:0 0000000000000000 RAID ZTE SDPSA_L-18i 2G [ 6.398251] scsi 14:2:0:0: RAID ZTE SDPSA_L-18i 2G 5.00 PQ: 0 ANSI: 5
复制代码
通过搜索可以查到 SDPSA_L-18i 实际上是 Microchip 的 SmartROC3100 RAID 卡。
核对产品资料确认使用 arcconf 命令行工具可以配置 RAID。
