Transceivers are a required modular interface when using fibre networking technologies. Whether SFP, SFP+, QSFP+, QSFP28 or QSFP56 - these transceiver modules slot into the compatible switch ports to deliver the fastest speed data transmissions whilst providing the lowest latencies.
A Host Bus Adapter (HBA) is an expansion card that plugs into a PCIe slot on the motherboard and provides fast, reliable non-RAID communication between the host system and the storage devices.
A RAID controller card is similar to an HBA, but can also add redundancy (RAID) for your data, help optimise performance, reduce latency, or even make smart decisions on whether to store data on an HDD or an SSD cache, depending on user needs.
Network cards are added to servers to enable connectivity to other users and devices in a high performance environment. SFP+ is a small form factor pluggable interface allows fibre optic cabling to be used as opposed to Ethernet offering greater speeds, distance and low latency when connecting to network switches.
