如何查看linux服务器的产品型号?# /opt/MegaCli -PDList -aALL如果没有RAID，通过hdparm命令查看即可
1、通过fdisk -l列出物理硬盘的设备名称 # fdisk 共两块硬盘：/dev/hda、/dev/hdd
2、通过hdparm命令查看指定硬盘的型号# hdparm -i /dev/hda# hdparm -i /dev/hdd
linux怎么查看内存型号因为网站开发的需求，需要对单位的服务器内存进行升级 。那么在linux中怎么查看内存型号呢?下面跟着我一起来了解一下吧 。
linux怎么查看内存型号
机器主板是nVidia Corporation MCP61，系统内存支持双通道内存技术 。
配置了4个DDRII DIMM插槽，支持DDRII 800/667/533内存，最大支持8G容量 。
为了尝试下双通道内存技术 ， 准备加一条与原来完全一样的内存条 。
电脑配置上只写了kingston DDRII512M 。
接下来就要用工具dmidecode(DMI table decoder)确定下内存频率了 。
dmidecode命令可以全面的显示你系统的信息，包括bios、cpu、内存等信息 。
例如：
[root@localhost testcase]$ sudo dmidecode --help
Usage: dmidecode [OPTIONS]
Options are:
-d, --dev-mem FILE Read memory from device FILE (default: /dev/mem)
-h, --help Display this help text and exit
-q, --quiet Less verbose output
-s, --string KEYWORD Only display the value of the given DMI string
-t, --type TYPE Only display the entries of given type
-u, --dump Do not decode the entries
-V, --version Display the version and exit
[root@localhost testcase]$ sudo dmidecode -t memory
# dmidecode 2.7
