「RAID-CONTROLLER」 – 硬件阵列卡

  CREATED BY JENKINSBOT

电池模块

Q:阵列卡的电池多久换一次?
A:商家说:“电池是自动充电的,只要开机,硬件正常,那么电池将自动充电”。我们觉得还是取决于具体的硬件,获取某些不支持自动充电,按理说应该都是支持的,不然就要关机更换电池,从设计上来说这并不合理;

Q:阵列卡的电池鼓包?是否该更换?是否会爆炸?
A:商家说:“不会爆炸,能够正常使用。手里的电池都有不同程度的鼓包”;

阵列卡直通技术

关于华为服务器阵列卡直通的问题_weixin_34348805 的博客-CSDN 博客
Mixed, Passthru, HBA and RAID mode SAS or SATA IO Controller card support (53573)

“直通”就是不做 RAID,系统也能识别到,比如 DELL 服务器的 Non-raid 模式。华为阵列卡 RD130、RD430 都支持直通;

HBA, Host-bus Adapter
