 ### 内存需求
 
-每个 DB 可以创建固定数目的 vgroup，默认与 CPU 核数相同，可通过 maxVgroupsPerDb 配置；vgroup 中的每个副本会是一个 vnode；每个 vnode 会占用固定大小的内存（大小与数据库的配置参数 blocks 和 cache 有关)；每个 Table 会占用与标签总长度有关的内存；此外，系统会有一些固定的内存开销。因此，每个 DB 需要的系统内存可通过如下公式计算：
+每个 Database 可以创建固定数目的 vgroup，默认与 CPU 核数相同，可通过 maxVgroupsPerDb 配置；vgroup 中的每个副本会是一个 vnode；每个 vnode 会占用固定大小的内存（大小与数据库的配置参数 blocks 和 cache 有关)；每个 Table 会占用与标签总长度有关的内存；此外，系统会有一些固定的内存开销。因此，每个 DB 需要的系统内存可通过如下公式计算：
 
 ```
-Memory Size = maxVgroupsPerDb * (blocks * cache + 10MB) + numOfTables * (tagSizePerTable + 0.5KB)
+Database Memory Size = maxVgroupsPerDb * (blocks * cache + 10MB) + numOfTables * (tagSizePerTable + 0.5KB)
 ```
 
-示例：假设是 4 核机器，cache 是缺省大小 16M, blocks 是缺省值 6，假设有 10 万张表，标签总长度是 256 字节，则总的内存需求为：4 \* (16 \* 6 + 10) + 100000 \* (0.25 + 0.5) / 1000 = 499M。
+示例：假设是 4 核机器，cache 是缺省大小 16M, blocks 是缺省值 6，并且一个 DB 中有 10 万张表，标签总长度是 256 字节，则这个 DB 总的内存需求为：4 \* (16 \* 6 + 10) + 100000 \* (0.25 + 0.5) / 1000 = 499M。
 
-注意：从这个公式计算得到的内存容量，应理解为系统的“必要需求”，而不是“内存总数”。在实际运行的生产系统中，由于操作系统缓存、资源管理调度等方面的需要，内存规划应当在计算结果的基础上保留一定冗余，以维持系统状态和系统性能的稳定性。
+在实际的系统运维中，我们通常会更关心 TDengine 服务进程（taosd）会占用的内存量。
+```
+taosd 内存总量 = vnode 内存 + mnode 内存 + 查询内存
+```
+
+其中：
+1. “vnode 内存”指的是集群中所有的 Database 存储分摊到当前 taosd 节点上所占用的内存资源。可以按上文“Database Memory Size”计算公式估算每个 DB 的内存占用量进行加总，再按集群中总共的 TDengine 节点数做平均（如果设置为多副本，则还需要乘以对应的副本倍数）。
+2. “mnode 内存”指的是集群中管理节点所占用的资源。如果一个 taosd 节点上分布有 mnode 管理节点，则内存消耗还需要增加“0.2KB * 集群中数据表总数”。
+3. “查询内存”指的是服务端处理查询请求时所需要占用的内存。单条查询语句至少会占用“0.2KB * 查询涉及的数据表总数”的内存量。
 
-实际运行的系统往往会根据数据特点的不同，将数据存放在不同的 DB 里。因此做规划时，也需要考虑。
+注意：以上内存估算方法，主要讲解了系统的“必须内存需求”，而不是“内存总数上限”。在实际运行的生产环境中，由于操作系统缓存、资源管理调度等方面的原因，内存规划应当在估算结果的基础上保留一定冗余，以维持系统状态和系统性能的稳定性。并且，生产环境通常会配置系统资源的监控工具，以便及时发现硬件资源的紧缺情况。
 
-如果内存充裕，可以加大 Blocks 的配置，这样更多数据将保存在内存里，提高查询速度。
+最后，如果内存充裕，可以考虑加大 Blocks 的配置，这样更多数据将保存在内存里，提高查询速度。
