What are Raid cards and HBA cards?

图片
  An raid card is a type of expansion card that can integrate multiple hard disks into a larger logical volume. This logical volume can be recognized by the operating system as a separate storage device to achieve efficient storage and access to large-capacity data. HBA card  is a PCIe device display technology. It can cut a physical device into multiple virtual devices, and each virtual device looks like an independent physical device, so that each virtual device can be allocated to different virtual machines. The difference between Raid card and HBA card Although both raid cards and HBA cards can enhance system performance, their application scenarios and functions are different. Here are the main differences between the two cards: 1. Different functions Raid cards are usually used in servers or high-performance workstations, which can integrate multiple hard disks into a logical storage device, and provide faster data read and write speeds and higher storage capacity. It ca...
