What Technology Should be Valued at the Next Generation Data Center Network

With the continual?expansion of business data center, the most several difficult problems for them are mainly about divided network environments, simple says, separate data network, separate storage network, separate calculation?network, protocols and there are different disadvantages of standards. Different networks need different cards, space, power and cooling infrastructures for their business. Interspersed interlaced network cabling may make many administrators feel dizzy. Aimed at different network environments, the company needs a professional technical team to support, manage, maintenance, these problems all block the forward developments of data center, let alone meet the future of cloud computing.?The figure shows?modern data center.

Modern data center

You may ask, what qualities we are taken for the next generation data center networks? Now we can see the characteristics, such as simplicity, virtualization features, can accommodate the expansion of the size of the data center, support higher bandwidth, low latency, non-blocking and so on. But as for these features, mainstream network equipment vendors aimed the advantages of their products and solutions to this goal, so if there is an architecture able to support these features do? The answer is yes, unified architecture (Unified Fabric), regardless of Cisco UCS. Brocade VCS, juniper3-2-1 plan, H3C’s unified fabric, also exist Unified Fabric. This page we just say two points.

The key technology under Unified Architecture (Unified Fabric)

Gigabit Ethernet

With the reduction of gigabyte networks at the server connections, Gigabit Ethernet share is rising, which maily due to the growth in the enterprise data center network traffic.In fact, with the 40G / 100G standard developments, it is sure that Gigabit Ethernet replacing the gigabyte networks, the birth of the Gigabit sfp+ transceiver?standard which has low power, sfp+ direct attach cable?can be achieved in the case of low-cost Gigabit Ethernet. And just mainstream might not be enough, the following what I will be introduced to toward greater success.

FCoE protocol (Fiber Channel over Ethernet)

FCoE is one of the most shining technology data center network currently, any vendors have to talk about the technology of the developments of their products. FCoE refers to the Fiber Channel over Ethernet, it can insert fiber channel information into the Ethernet packet, so that the Fiber Channel storage devices -SAN server requests and data can be transmitted over an Ethernet connection, without the need for a dedicated Fiber Channel fabric . Its main benefits: First, make storage traffic and network traffic share the same Ethernet cable and a fusion of the card, simplifying management and reducing energy consumption. Second, provide the same performance with optics. The third is the ability to integrate effectively existing SAN.

Finally, you know, now i work for Fiberstore and in our website, we can provide the most advanced technology and the most effective way to help you solve the fiber optics problems, and at the same time, we also provide all the fiber optic products, such as 10 100 1000base t ethernet sfp, qsfp 4x10g aoc7m and glc fe 100lx rgd to buy. If you are interested, take a decision for it.

Choose and Get SFP+ Module and Cables Effectively

According the standard of the IEEE 802.3 ae committee ratified the 10 Gigabit Ethernet and with the general specification, it defines a number of fiber optic interfaces. These standard interfaces attempted to satisfy a number of different objectives including support for MMF and SMF compatibility. They include SFP+ sr transceiver, sfp+ lr transceiver, SFP+ er transceiver, SFP+ zr transceiver, Copper CU SFP+, maybe some one do not know the last one, related product you can see: cisco sfp h10gb cu2m. Their applications are using 10 Gigabit Ethernet and 2x/4x/8x/16x Fiber channel, for example, the cisco SFP+ module, the optical interoperability with 10Gbase XENPAK, 10 GBase X2, and 10GBase XFP interfaces on the same link; the device can olug into an Ethernet SFP+ port of a Cisco switch, just do not need to power down if installing or replacing, these are all its adavantages. the Cisco quality ID feature enables a Cisco platform to identify whether the module is certified and tested by Cisco. Then many people also think this problem that when we use the cisco transceiver with cisco switches or even patch cables, do they need the vendor ti phydiacally hang the access points and do they need eo configure the access points and how many buildings will the access points be installed into, well, the next paragraph will give you the answer.The vendor needs to phydically hang the access points and the points are controller based and they will need to be configured. All access points are to be installed on the ceilinf, the only exception would be in gym where it would to be mounted to the ceiling beam. The Figure show that push the SFP Front of the module to make it into the slot.

plug into SFP+ Module

Many people know that SFP, SFP+ and they are not familiar with 40G QSFP, then i will introduce one kind of QSFP transceiver to you. The 40 Gb/s QSFP+ transceiver. It is a kind of fiber optical modules with four independant optical transmit and receiver channels, it combines the higher density attractions of modules with some the key advantages normally associated with SFP+ modules. And another product you also can not forget, sfp+ direct attach cable. In Fiberstore, there is a similar attach cable, sfp+ direct attached twinax copper,it is suitable for very short distances and offer a usful way to connect within racks and across adjacent racks. Cisco offers passive twinax cables in lengths of 1, 1.5, 2, 2.5, 3 and 5 meters, and active twinax cables in lengths of 7 and 10 meters. related product: 0.5 m sfp+ cable.

We have real wide variety of fiber optic transceivers, I do believe that it is a quite great choice for you.

Special Instructions of Cisco SFP Transceivers

The Cisco SFP transceivers are designed to change the serial electric signals to the serial optical signals which mainly maintain gigabit Ethernet, includes fiber channel and SONET/SDH, it provides a beneficial way, adopt the method of resolution in the university campus, data center, metropolitan areas, ring networks and store web site.

Ethernet converter net from one end to another in order to let more systems with different thread accurately corresponding associated Ethernet cable. This is likewise being used within the similar set up once there are several computers functioning with varying types of technology. In addition, optical fiber cable can defy from any type of electronic equipment, mobile phones and wireless complex which usually don’t like with the traditional Ethernet, such equipment which was exposed loses the signal interference. In this case, as converted into optical fiber Ethernet, because it provides a quick and excellent signal. The SFP is by the maritime safety administration or from IBM, lucent, Siemens, ample/TYCO and Infineon Multi-source is unqualified, this is the main content of the network vendor management. The SFP transceivers have the following advantages:

1. For reasons of that you can insert, optical fiber interface, still can modify on the end pace of the creation of the card.

2. It is able to accommodate a lot of connector interface or a combination of LX SFP and SX.

3. Since the basket of SFP transceiver is placed in the PCB in order to accept stated, it can reduce the additional program, thereby reducing the costs. As a result, it made it easier to reconfigure and replacement.

4. Because of optical element, SFP transceivers enhanced reliability. It allows the use of higher the temperature.

Cisco SFP is interchangeable, in addition to its flexibility, from a wide range of Cisco project. It can be used with Cisco 1000BASE-TX, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-EX, 1000BASE-ZX, or 1000BASE-BX10-D/U in a port through the port joint.

Cisco SFP modules need to connect the one-piece structure to another, because it plays an important role in the most commonly used information technology business.

The SFP transceiver modules are generally hot-pluggable I/O devices that can easily get plugged into the module sockets. The transceiver efficiently connects the electrical circuitry of the module to the copper or optical network. Users can utilize any combination of SFP transceiver modules that the Cisco transceiver device assists. The only thing to take note here is that every port should match the wavelength requirements on the other end of the cable and that the cable should not exceed the concerned cable length in order to ensure consistent communication. It is recommended that users utilize the SFP transceiver Cisco modules only on the Cisco instrument. Every single Cisco SFP transceiver module assists the Cisco quality identification that enables a Cisco router or switch to identify and authenticate that the transceiver module is examined and approved by Cisco. Now I introduce SFP-10G-ZR compatible with Cisco devices in Fiberstore. it is cheaper than Cisco company. The SFP-10G55-80-CO series single mode transceiver is small form factor pluggable module for duplex optical data communications of 10G.

10GB Ethernet SFP Cable Configuration Guidelines

The 802.3 ae supplement that initially defined 10 Gigabit Ethernet was adopted in 2002 and recently Cisco to launch a product compliant with IEEE 802.3ae 10GBASE-SR/SW, Cisco SFP 10G SR, the SFP-10G-SR multi-mode transceiver in Fiberstore is SFP+ module for duplex optical data communications such as 10GBASE-SR and 10GBASE-SW. it is fully compatible with Cisco devices. This module is designed for multi-mode fiber and operates at a nominal wavelength of 850 nm.

10GBASE-SR

The direct attach cables and their SFP module use an electrical signaling interface called SFI, which is defined as the “SFP + high-speed serial electrical interface.” The SFI definition enables 10 Gb/s operation over a single differential signaling path in each direction for a total of two pairs, or four wire connections. The twinax cable includes the two pairs of single-carrying wires in a coaxial cable format, providing high performance and stable signaling over the length of the cable.

The serial link transfers scrambled data at 10.3125 Gbaud to accommodate both data and the overhead associated with 64B/66B coding. The self-clocked nature eliminates skewing between clock and data signals. The SFI link requires a 100 ohm cable impedance, while the signal termination electronics provide both differential and common mode suppression of signal noise and reflections. 10GSFP-PC-30-1-CO series also provides SFP-H10GB-CU1M to compatible 10Gbase-CU SFP+ cable, it can connect SFP+ passive twinax cable assembly, and the length is 1 mete, compliant to SFP+MSA, This cable offers the same function with Cisco SFP-H10GB-CU1M and it is fully compatible with Cisco devices.

The SFP+ MSA specification for direct attach cables note that 10G SFP + CU connections can only be used on systems with common power grounds. The power supplies for the Ethernet switches, and for any computers or other switches that are connected to them over direct attach cables, must themselves be connected to the same local power grid with a common ground between all devices, as a difference in ground potentials between systems connected with DA cables could result in electrical damaged to the interfaces or the devices.

The direct attach cables used in the 10G SFP+CU system come in a limited range of sizes, worth lengths in the range from 0.6m to 7m being the most widely sold. It is up to you to verify which cable lengths are supported by your vendor, and whether the cable can be active or passive. Some vendors support both types of cables on their SFP+ ports, and others do not.

The twinax cable itself is relatively stiff, and many present difficulties if you need to route it through tight spaces. There are two conductors in each twinax cable, with two twinax cables inside a common sheath providing a total of four conductors for signals. As an example, one vendor’s direct attach cable has an outer diameter of 0.180 inches, or roughly 3/16 inch. The minimum bend radius for this cable is one inch. If you bend the cable any tighter than this, it may affect the signal quality.

For optical cable, fiber channel uses the SFP cable. The SFP provides for greater port density and meets the need for smaller connectors than the older SC duplex connector and gigabit interface connector (GBIC). A multi link communication path between two N_ports may be made up of links of different technologies. For example, it may have copper coaxial cable links attached to end ports for short-distance links. with single-mode optical fibers for longer-distance links between switches separated by longer distances. By providing a variety of physical interface options. Fiber channel allows an implementation to select the most appropriate option for a particular scenario.

Fiberstore is an industry’s leading supplier of optical communication products, its products are widely used in telecommunication systems and data communications network. With the strong compatibility of the products what exactly match the mainstream manufacturer’s equipment.
