## 3. 存储(磁盘)
### 3.1 存储空间
计算公式：测点数量 * 采样频率（Hz）* 每个数据点大小（Byte，不同数据类型不一样，见下表）
<table style="text-align: center;">
<tbody>
<tr>
<th colspan="4"> 数据点大小计算表 </th>
</tr>
<tr>
<td> 数据类型 </td>
<td>时间戳（字节）</td>
<td>值（字节）</td>
<td>数据点总大小（字节）</td>
</tr>
<tr>
<td>开关量（Boolean）</td>
<td>8</td>
<td>1</td>
<td>9</td>
</tr>
<tr>
<td>整型（INT32）/ 单精度浮点数（FLOAT）</td>
<td>8</td>
<td>4</td>
<td>12</td>
</tr>
<tr>
<td>长整型（INT64）/ 双精度浮点数（DOUBLE）</td>
<td>8</td>
<td>8</td>
<td>16</td>
</tr>
<tr>
<td>字符串（TEXT）</td>
<td>8</td>
<td>平均为a</td>
<td>8+a</td>
</tr>
</tbody>
</table>

示例：1000设备，每个设备100 测点，共 100000 序列，INT32 类型。采样频率1Hz（每秒一次），存储1年，3副本。
- 完整计算公式：1000设备 * 100测点 * 12字节每数据点 * 86400秒每天 * 365天每年 * 3副本/10压缩比 / 1024 / 1024 / 1024 / 1024 =11T
- 简版计算公式：1000 * 100 * 12 * 86400 * 365 * 3 / 10 / 1024 / 1024 / 1024 / 1024 = 11T
### 3.2 存储配置
1000w 点位以上或查询负载较大，推荐配置 SSD。
## 4. 网络（网卡）
在写入吞吐不超过1000万点/秒时，需配置千兆网卡；当写入吞吐超过 1000万点/秒时，需配置万兆网卡。
| **写入吞吐（数据点/秒）** | **网卡速率** |
| ------------------- | ------------- |
| <1000万 | 1Gbps（千兆） |
| >=1000万 | 10Gbps（万兆） |
## 5. 其他说明
IoTDB 具有集群秒级扩容能力，扩容节点数据可不迁移，因此您无需担心按现有数据情况估算的集群能力有限，未来您可在需要扩容时为集群加入新的节点。
