In the early SAN storage system, the data transfer between the server and the switch was done through optical fiber, because the server was transferring the SCSI instruction to the storage device, could not take the IP protocol of the ordinary LAN network, so it needed to use FC transport, so this SAN is called Fc-san, And later appeared with the IP protocol encapsulated SAN, can completely walk the ordinary LAN network, so called Ip-san, which is the most typical of the now popular iSCSI. Both

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

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

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

To re-scan the disk, you can use the following methods to perform the sw

Action steps are as follows: ① Open the (INSMGMT console window, select the DNS server for which you want to create a forward lookup zone, and then select the Action-New Zone command in the menu bar, as shown in Figure 1

This article describes how to set the Python time zone and how to query the time zone using pytz. Concept and transformation of time zone First, you need to know the conversion relationship between the time zones. In fact, this is very simple: subtract the local time from the local time zone, and the rest is the Green

Concept and transformation of Time Zone First, you need to know the Conversion Relationship Between the time zones. In fact, this is very simple: subtract the local time from the local time zone, and the rest is the Greenwich Mean Time. For example, Beijing time is +, and + after the subtraction. Therefore, GMT is adopted.Add Greenwich Mean Time to the local time zone
