|+------------------+ Memory high end When a function call occurs in a program, the computer does the following: First, the parameters are pressed into the stack;The contents of the Save instruction Register (IP) are returned address (RET); The third is the base address that is sent to the stack(FP), then copy the current stack pointer (SP) to the FP as the new base address, and finally the localAmount of space, the SP minus the appropriate value. Take the following procedure as an example:

disadvantage of this solution is that many vSphere software functions are unavailable, such as FT, Snapshot, Suspend, and vMotion. Vf vm DirectPath SR-IOV SR-IOV VF solves the problem that a single PCI device cannot be shared by multiple virtual machines under Full-function. SR-IOV requires support for adapter and/VMM/Hypervisor collaboration. An adapter can register multiple independent interrupts (PF and VF) on the chipset. Each interrupt corresponds to an independent PCI device on the VMM/Hy

(CNA) Cables Fcoe Switches Converged network adapter A CNA provides the functionality of both a standard Nic and an FC HbA in a single adapter and has lidates both types of traffic. CNA eliminates the need to deploy separate adapters and cables for FC and Ethernet communications, thereby cing the required number of server slots and switch ports. CNA offloads the fcoe protocol processing task from the server, thereby freeing the server CPU resources for applica

Ethernet is a local area network technology developed in the the 1980s, because of its easy to use, low price and high speed, it soon became the mainstream of LAN. With the advent of Gigabit Ethernet (GbE) and the emergence of Gigabit Ethernet (10GbE), as well as the low cost of direct architecture of GbE and 10GbE technology in optical fiber, Ethernet has entered the metropolitan area and wide area network

protocols, such as SAS, Fibre Channel over Ethernet (FCoE), and Internet SCSI (ISCSI), is also present, as is more Domain-specific protocols like ISCSI Extensions for remote Direct Memory access (Rdma-iser) and the SCSI RDMA Protocol (S RP), which extends SCSI over RDMA for Infiniband.The emergence of Ethernet as a storage protocol have been fully realized in Linux, as it illustrates the power and Flexibil ity of these approaches. Further, 10-gigabit Ethernet (

Some knowledge about storageAccording to the different transmission protocols, the network card can be divided into three kinds, one is the Ethernet card, the second is the FC network card, the third is the iSCSI network card. Ethernet Card: The Scientific name Ethernet Adapter, the transmission protocol for the IP protocol, generally via fiber optic cable or twisted pair with Ethernet switch connection. The interface types are divided into optical and electrical ports. Optical ports ar

, which greatly reduces the number of network devices, the interfaces of servers to the network, and cables connecting different clusters. For example, the number of interfaces may be reduced to two 10GbE ports, two cables, and two switching interfaces. Another benefit of consolidation is the ability to support FCoE's CNA to provide a standardized approach to fibre SAN connectivity, which simplifies the physical architecture and its support. For I/O c

, thus forming a network of hardware devices. So, the fiber-optic network card is the name in the end is the fiber port HBA card? In fact, the fiber-optic network card that you often refer to is the HBA card in the Fibre Channel networks. Because of the different transmission protocol, the network card can be divided into three kinds, one is Ethernet cards, the other is FC network card, the third is iSCSI network card. • Ethernet Card: Scientific name Ethernet Adapter, transport protocol fo

the PCI Express interface will be available early next year, the 10G Ethernet chip for optical fiber and copper wires supporting TCP/IP uninstallation will also be available within a year and a half. Analysts said it would take several years for chip manufacturers to determine all the details about how they can accelerate TCP/IP uninstallation. At the same time, Intel released its 10 Gbit/s server NIC-PRO/10GbE SR, which uses XPAK connector to connec

What are the hardware requirements for deploying FCoE? What are your suggestions for optimizing FCoE deployment? In general, FCoE needs a switch that can bridge the data center to datacenterbridging, DCB) to expand the traditional Ethernet so that it is suitable for transmitting storage traffic without losing data. Some, but not all) Ethernet vendors support the dcb feature of the 10GbE switch. At the same time, the converged network adapter converged

In addition, Linux fully supports 10 Gbit/s Ethernet (10-gigabit Ethernet, 10GbE) and allows the construction of high-performance SAN. You can also find the ATA over Ethernet (ATAoE) protocol, which extends the ATA Protocol through the ubiquitous Ethernet protocol. Network attached storage Last but not least, NAS. NAS is a combination of network storag

category. Some of the more common cable) solutions include micro-coaxial cable, strip cable with controllable impedance, dual-axis cable, and shielded twisted pair cable. Other cable types based on copper wires include parallel cables, four-axis cables, and the RG series microwave cables and Microwave Coaxial Cables ). There are three types of optical fiber cables: Single-mode, multimode, and plastic optical fiber POF ). The single-mode is characterized by only one Z optical fiber. It is more e

. Gigabit Ethernet will be replaced by 10GbE, 40GbE, and 100GbE network connections. A 10GbE structured network (where traffic can flow in all directions) will facilitate energy conservation, manageability, and flexible use of computing resources through network virtualization. At the same time, in order to improve the speed between the top switch and the server Nic in the data center and reduce the cost of

The maximum rate of Ethernet switch stack is faster, Which is multiple times faster than the port rate of the switch. Not all switches support Ethernet switch stack, when the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect a vswitch: Ethernet switch stack and cascade.
