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.
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.
