1. What Is RAID RAID technology combines multiple physical hard drives into a single logical hard drive, so the operating system sees it as one storage device. There are two ways to implement RAID: hardware and software. A hardware implementation is a RAID controller, a standalone hardware device responsible for RAID control and management.

1. What RDMA Is RDMA (Remote Direct Memory Access) is a technology created to solve the delay of server-side data processing in network transmission. With TCP/IP transmission, data passes through the network stack, then through the NIC to be sent; after the receiver receives it, the data is reassembled according to sequence numbers.

1. InfiniBand Network InfiniBand (abbreviated IB) is a computer network communication standard for high-performance computing. It offers extremely high throughput and very low latency, and is used for data interconnection between computers. InfiniBand is also used as a direct or switched interconnect between servers and storage systems, as well as between storage systems themselves.
