This term is usually applied to Fibre Channel HBAs in systems such as Apple Xsan.
These are PCIe cards that you can install into your Server CPU to add a fiber channel to your server or computer that does not already have it.
A Host Bus Adapter (HBA) is a circuit board or integrated circuit adapter that connects physically between the host computer (computer or server) and networks and storage devices.
In addition to the physical connectivity it also provides, HBA also handles the input/output (I/O) process.
Using the HBA adapter card, that host computer's microprocessor does not have to manage data storage and retrieval functions, increasing performance.
Benefits of using Server HBA Card
Let's take a look at the most important uses for the HBA adapter card.
Creates a physical connection between the host computer and the Server Network Interface Card or devices that are compatible.
Perform processing of input and output.
Transfer data between connected devices and the host computer.
Please make use of the host system by performing as the data storage and retrieval tasks by itself.
What are Server HBA Card?
HBA is an I/O adapter that connects the host's I/O port to the computer's memory system.
Based on this definition, the same way a video card connects with the video bus and memory, and that is why the card for the network is linked with the bus for the web and Server Cache Memory.
The SCSI-FC card is connected to either the SCSI or the FC bus and the memory, so they can be considered HBA.
There are different f for Server HBA card like FC-HBA and iSCSI HBA to come shortly. However, HBA is commonly used for SCSI.
Adapters along with NIC are designed for FC; NIC is also utilized to connect Ethernet and Token Ring.
We usually refer to the fiber-optic network card as it is the Fiber Channel network HBA card. Because of the various transmission protocols.
Three Types of Network Card
Ethernet card.
FC Network card.
ISCSI network card.
Ethernet Card
The name of the Ethernet Adapter. The protocol for transmission is IP. It is typically linked to the Ethernet switch via optical cables nor Twist cables.
The type of interface is split into electrical port and optical port. The visual interfaces typically transmit data via optical fiber cable.
These interfaces are usually SFP (2Gb per second) and GBIC (1Gb /s). The interfaces used comprise SC, ST, and LC.
The current electrical port is interface type RJ45 is used to connect the twisted pair. They are also linked with the coaxial cable interface but are less popular now.
FC Network Card
Also known as fiber channel network cards. are the acronyms for Fiber Channel HBA.
This transmission method is one of the Fibre Channel protocols, generally linked to the Fiber Channel switch via a fiber optical cable.
The type of interface was split into electrical port and optical port. The visual interfaces typically transmit data via optical fiber cable.
These interfaces generally are of the type SFP (transmission rates of two gigabytes seconds) or GBIC (1Gb per second), and the respective interfaces include SC and LC.
The type of electrical interface is typically DB9 pins or HSSDC.
ISCSI Network Card
ISCSI Network is the name iSCSI HBA, which carries the iSCSI protocol using the same interface as the Ethernet card. Ethernet card.
