NGFF (Next Generation Form Factor), as the name suggests, is the standard of Form Factor. It is tied with NGFF for 2.5 "instead of PCIe. (In addition, NGFF has now been renamed M.2. We 'd better keep pace with the times and change it to M.2 .)PCIe is a bus standard, tied with SATA.NVMe is a new transmission standard for hard disks and replaces the current AHCI.Why do people always associate NGFF/M.

This ID is the instance number of the corresponding Fiber Channel Driver. The fcip driver uses the FARP fiber channel extension service to resolve WWN to fc port id. The driver also supports inARP to resolve WWN and Port_ID to IP addresses. The specific steps for configuring fc hba as an Ethernet Card ar

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

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

freesclae i.mx6 Linux PCIe Driver source code Analysis Turn from: Http://www.lai18.com/content/2232856.html Recently, a tool was needed to test whether PCIe link was successful, but since PCIe drivers are in kernel space, it is necessary to first analyze the I.

3.9 maximum PCIe Performance PCIe performance has an unexpected impact on the size and alignment of upstream read/write transactions from a PCIe proxy to the publishing of host-side memory. As a general rule, in terms of bandwidth and latency, the best performance is to align the starting address of upstream read/write at the 64-byte boundary and ensure that the

Multifunction PCIE Switch IX: Issues needing attention in a single NT system1. Difference between single NT and dual NT systemNTB is typically used on dual-or multi-control systems to achieve cross-node data transfer. On a system composed of multiple nodes, there is usually a NTB chip on each node to achieve the system-wide address space partitioning and routing. As the name implies, single NT refers to the use of a

recently, the bandwidth concept and calculation of PCIe are somewhat blurred, and most of the online search data is a mold, This is calculated by the following formula:Parallel bus bandwidth (MB/s) = parallel bus clock frequency (MHz) * Parallel bus bit width (BIT/8 = B) * Transmission of several sets of data per clock (cycle)In particular, after the calculation is not very easy to understand, and then after consulting the information, the following u

PCI-X and PCIe bus specifications require that their devices must support the capabilities structure. The basic configuration space of the PCI bus contains a capabilities pointer register, which stores the head pointer of the capabilities Structure linked list. A PCIe device may contain multiple capability structures. These registers form a linked list, as shown in. Each capability structure has a unique I

I talked to users and vendors about how SSD (solid state drive) is used, I found that most people think that server SSDS must be ultra-high-performance SLC (single-layer unit) PCIe flash cards manufactured by manufacturers such as Fusion-IO, micron, Virident, or LSI. Although most people know that the mainstream SAS or SATA interface SSD is in the 2.5 inch format, they seem to think that these devices are only suitable for laptops or enthusiasts. Of c
