1).查看一共几块物理硬盘：

# MegaCli64 -LdPdInfo -a0 -Nolog | grep -E "Virtual Drive:|Slot Number:" | xargs | sed -r 's/(Slot Number:)(\s[0-9]+)/\2,/g' | sed 's/(Target Id: .)/Physical Drives ids:/g' | sed 's/Virtual Drive:/\nVirtual Drive:/g'  #回车

Virtual Drive: 0 Physical Drives ids:  0,  1,  2,  3,  4,  5,  6,  7,  8,  9,

2).查看raid级别、磁盘单块容量和总容量：

Linux服务器硬盘种类：

Linux中常用的硬盘类型及其特点简介 (linux 硬盘类型)-数据库运维技术服务

Linux服务器硬盘种类：

1). SATA硬盘

SATA（Serial Advanced Technology Attachment）硬盘是一种串行接口硬盘，它代替了以前的Idea接口硬盘。SATA硬盘的更大特点是传输速度快，数据传输速度可以达到6GB/s。同时，SATA硬盘的安装和拆卸也非常方便，只需要通过SATA数据线和SATA电源线连接即可。

2). SCSI硬盘

SCSI（Small Computer System Interface）硬盘是一种高端硬盘，适用于需要大量数据传输的场合，如服务器和工作站。SCSI硬盘的传输速度快，同时支持多个设备的并联。此外，SCSI硬盘还有着较高的运行稳定性和可靠性。

3). SAS硬盘

SAS（Serial Attachted SCSI）硬盘是一种高性能的硬盘，它将SCSI接口与SATA接口相结合。SAS硬盘的传输速度快，同时还可支持多个设备的并联。此外，SAS硬盘还有着较高的安全性和容错性，可以保证数据的安全性和完整性。

4). IDE硬盘

IDE（Integrated Drive Electronics）硬盘是一种传输速度较慢的硬盘，通常用于家庭和办公环境中。与SATA硬盘不同，IDE硬盘需要通过IDE数据线和IDE电源线进行连接。虽然IDE硬盘的传输速度较慢，但其价格相对较便宜，适合一般用户使用。

5). SSD硬盘

SSD（Solid State Drive）硬盘是一种采用闪存芯片作为存储介质的硬盘，与机械硬盘相比，SSD硬盘的传输速度更快，能够提供更高的读写性能。此外，SSD硬盘还有着较高的耐用性和可靠性，可以支持较长时间的使用。
