hba cable

the normal network card or ordinary fiber card confused. Of course, some iSCSI HBA cards can be used as a normal network card, but it is very luxurious to consider from the price. The general definition of HBAs is the I/O adapter that connects the host I/O bus and the computer's memory system. According to this definition, like the video card is connected to the bus and memory, the network card is connected to the bus and memory, SCSI-FC card is con

Host Bus Adapter-Host Bus Adapter (HBA) is a Host Bus Adapter that provides input/output (I/O) between servers and storage devices) A circuit board and/or integrated circuit adapter that processes and physically connects. Because the HBA reduces the burden on the master processor in data storage and retrieval tasks, it can improve server performance. An hba and t

1, first introduce what is the HBA. Here the HBA, the full name FC HBA, that is, fibre Channel Host bus Adapter. In a FC network, a host (such as a server) needs to connect to a FC network, FC storage device (such as a SAN), using an interface card, just as Ethernet cards are required to connect to Ethernet. This interface card is called FC

In Solaris, how to configure the fc hba to an Ethernet Card IPFC can easily set a fc hba to an Ethernet card, which is of great significance. In some work sites, if you need to copy a large amount of data through the network, you will often find that the speed of the Gigabit Nic is insufficient, and network aggregation cannot compensate for bandwidth insufficiency, at this time, you can make full use of the

The solutions are:1. Use MS Utility "Fcinfo.exe" (Fibre Channel information Tool (fcinfo)) to view the WWN number of the HBA card.The Fcinfo tool is installed on a Windows system that needs to view the WWN number, and then, in the Start menu, type "CMD" in "Run" and enter command-line mode, and you can see the WWN number of the host HBA by entering Fcinfo.2, after searching, find article finds

The network cable is already inseparable from our life. Because we often use the network cable, we need the network cable to access the Internet. Therefore, we need to learn how to make the network cable so that we can better control our life in Russia, Okay. Let's just talk about the network connection methods. Th

This means that th
