Examples of hardware configuration
The table provides several examples of hardware configurations: 

部署环境（硬件）需求
主机数量：50台、网络设备数量：20台。总计监控点位70个。
根据官方提供的硬件设备需求表，提出以下硬件需求
CPU：1核。
内存：2G
磁盘容量：45G
磁盘容量计算方式：
linux操作系统+软件部署：6G
服务器：50个点，每一分钟读取一次数据，每秒数据量为50*30/60=25个/秒。
网络设备：20个点，每20秒读取一次数据，每秒数据量为20*30/20=30个/秒。
zabbix每秒处理的数据量：55个/秒
一条记录大小：5字节
保存记录的值（一个月）：24*30*3600（一个月的秒）*55*5=712800000字节（约为6.6G）
趋势数据（5年）：2100个*24小时*356天*128字节（一条趋势数据大小）*5=11G
事件记录保存（一年）：1年*365天*24小时*3600秒*130字节（一条事件记录的大小）=4.1G
按照保存记录的值3个月，趋势数据5年，时间保存记录的值2年进行计算：
所需磁盘容量为：6G+6.6G*3+11+4.1G*2=45G
