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:
# MegaCli64 -LDInfo -Lall -aALL

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。
