The HBA (Host Bus adapter) is a circuit board and/or integrated circuit adapter that provides input/output (I/O) processing and physical connectivity between servers and storage devices. Because HBA relieves the burden of the main processor in data storage and retrieval tasks, it is able to improve the performance of the server. An HBA and the disk subsystem attached to it are sometimes referred to together as a disk channel.
1.It can be distinguished from the chip identification. The chip of fiber network card is generally Intel/Broadcom, which uses Intel's chip, and the chip of HBA card is generally Emulex/Qlogic. Of course, this is not the primary solution, because Emulex/Qlogic also has fiber cards, and Broadcom has HBA cards;
2. Can be divided from the indicator light, fiber network card generally has two indicators, Link and Act light; The HBA card of Emulex is green and orange, and there are two raised lines on the baffle. The HBA card of Qlogic has three indicator lights.
3, Can be distinguished from the rate: fiber network card mostly 1G and 10G, HBA card mostly 4G and 8G;
4. It can be distinguished from the interface appearance: the interface of the optical fiber network card is narrower than that of the HBA card;
5, can be distinguished from theconfiguration: optical fiber network card and ordinary network card, need to configure IP, while HBA card connection FC JBOD, without configuration IP;
Optical fiber network card and HBA card (fiber card) can be used on the switch, and Shenzhen HDV phoelectron technology LTD is specialized in this kind of products as the main sales of the company, the best-selling products cover more: Ethernet switches, fiber switches, Ethernet fiber switches, etc., the above switches can be used in a variety of environments, to provide more choices for users with different needs, welcome to understand, we will provide the best quality service.
