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.

Talk About QSFP 40G SR4 to 4 SFP 10G SR Transceiver Module

As we know, SFP+ and QSFP+ transceiver module and fiber optic cables bring to people a wide variety of high density and low power 40 Gigabit, 10Gigabit, 1 Gigabit, and 100 Megabit Ethernet connectivity options over fiber or copper media.

cisco

The example of 40G QSFP module will bring us to have knowledge of it. In 40G QSFP module data sheet, we can see that QSFP 40G SR4 break out in a 4 x 10 G mode for interoperability with 10Gbase sr interfaces up to 100m and 150m on OM4 and OM3 cables respectively, in another word, if i connect Nexus 55772UP equipped with “six true QSFP ports” to Nexus 7706 using QSFP 40G SR4 on the side of 5572UP, and 4 x cisco SFP 10G SR on the side of 7706 Somehow, i think that this is not impossible, but someone thinks that there are fiber optic cables with 40G interface on one side and 4 x 10G SFP (LC connector) on the other side. We can breakout the single 40G port into 4 separate 10 G ports and use a QSFP to 4 LC breakout cable to link one or more of 10G ports to the 7706.

In fact, Cisco QSFP 40G SR4 module supports link lengths of 100m and 150m, respectively, on laser optimized OM3 and OM4 multimode fibers. It primarily enables high bandwidth 40G optical links over 12 fiber parallel fiber terminated with MPO/MTP multifiber connectors. It can be used in a 4 x 10G mode for interoperability with 10Gbase sr interfaces up yo 100m and 150m for OM4 and OM3 cables, respectively. The worry free 4 x 10G mode operation is enabled by the optimization of the transmit and receive optical characteristic of the Cisco QSFP 40G SR4 to prevent receiver overload or unnecessary triggering of alarm thresholds on the 10Gbase SR receiver, at the same time being fully interoperable with all standard 40Gbase sr4 interfaces. 4 x 10G connectivity is achieved using an external 12 fiber parallel to 2 fiber duplex breakout cable, which connects the 40GBASE SR4 module to four 10GBASE SR optical interfaces. Cisco QSFP 40G SR4 is optimized to guarantee interoperability with any IEEE 40GBASE SR4 and 10GBASE SR (in 4 X10G modes).

The transceiver consists of parallel electric and optical products along with both transmitter and receiver functions as a single module. It is designed to be compliant to IEEE 802.3-2012 for 40G SR4 over 100 m of OM3 multimode fiber at a rate of 41.25 Gbps. This transceiver module has an option to work with four independent SFP 10G SR, IEEE 802.3 Clause 52 Compatible 10 G transceivers through an MPO-to-LC breakout cable (compliant at 100 m over 50 μm OM3 fiber). The transceiver is also fully compliant with the QSFP+ MSA specification SFF-8436 Shown at the Figure.

10gbase sr

To support a good increasing range of 10 and 40 Gigabit Ethernet applications, Fiberstore offers many qsfp transceiver types, each optimized for a different media and distance reach (LR4, PLRL4, 40G SR4, XSR4, CR4, CR, SRL, SR, LRL, LR, ER, ZR, and DWDM). Additionally, fiber SFP+ ports also support 3 Gigabit Ethernet SFP transceiver types for single mode fiber, multimode fiber, as well as Cat 5 copper cable.

Address Common Questions When Using the Compatible Devices

When we begin to come into compatible products industry, there is always a problem that confused us, we are not sure if a device can be compatible with another device in different brands, even after they connected, did not know what would happen, well, this page I will explain the problem with the actual example.

For example, we need to connect Dell M6330 blades switches to a HP 2910al by fiber sfp+ over sr (50/125 um OM3 fiber from tyco). Then i ordered the SFP+ module for the 2910al (J9008A), two transceiver modules for the DEll switches (one each) and 4 x Dell 10gbase-sr sfp LC LC transceiver. And if all the connection between the M6220 done well, but when i plug the Dell transceiver into the switch there is no link up, what it means that if the HP switch refused to work with the Dell transceivers, but there is no event log notice of incompatibility, Then the questions is, if i can connect the HP switches to Dell by SFP+, or do you know if using non-HP brand SFP+ transceivers will work with the HP transceiver?

sfp

Well, in this issue, If you are indeed using optical transceivers in the switches, then no switch has any idea about what transceivers are in any other switch. Switches only know about the directly connected (plugged-in) transceivers. Now, as for the transceivers themselves. The J9008A is simply an expansion module. HP ProCurve switches will not accept non-HP ProCurve transceivers. So, if you have been trying to use the Dell SFP/SFP+ transceivers with the HP 2910al, that would be your problem. You are required to obtain HP ProCurve transceivers and use those.

sfp module

In general, we have to say that HP switches do not accept non-hp transceivers, such as Cisco, Dell, Juniper, Netgear and so on…You can’t plug a Dell transceiver in a ProCurve switch and expect it to work. Although there is a MSA (Multi Source Agreement) for SFP transceiver, in practice HP switches do not accept non-HP transceivers. Cisco equipment also can only utilize the Cisco SFP module and other brand module or equipment is not supported. If you just plug in the other module, Cisco port information will be displayed on the Unsupport or unknown. In simple terms, as for the unknown GBIC, Cisco device does not provide any warranty. In a word, when we choose the device, we just have to choose the same brands products, compatible products also can be used. Above the Figure shows that the popular compatible module in our Fiberstore.
