本文链接地址: smartctl获取raid卡下intel ssd寿命

我们在线上用了大量的Intel ssd盘,总所周知的是ssd盘是有寿命的,在实际的使用中能够监控ssd盘是非常有帮助的。

我们通常是在raid卡下用intel ssd盘做10level的阵列,通常的工具很难读出它的寿命信息等。 经过intel和社区的努力,对intel ssd的寿命读取代码集成到了smartctl中去了, 这下我们方便了。

先交代下我们的环境:

硬件和操作系统:
System | Huawei Technologies Co., Ltd.; Tecal RH2285; vV100R001 (Main Server Chassis)
Release | Red Hat Enterprise Linux Server release 5.4 (Tikanga)
Kernel | 2.6.18-164.el5
Architecture | CPU = 64-bit, OS = 64-bit

raid卡控制器:
# RAID Controller ############################################
Controller | LSI Logic MegaRAID SAS
Model | MegaRAID SAS PCI Express(TM) ROMB, PCIE interface, 8 ports
Cache | 256MB Memory, BBU
BBU | 96% Charged, Temperature 23C, isSOHGood=
