Datacenter migration，Now that consumers and businesses are driving exponential growth in data services, data centre operators must continue to look for ways to offer higher network speeds.The enterprise data center must support existing applications while setting up new ones.In just a few years ago, Wan Zhao Ethernet is connected to the server, storage, routers and switches "high-speed network" solution, but the speed of Ethernet is now has risen from 25 billion and 50 billion - bit extensions to 100/200 one billion, could even reach 400 billion.In any industry, the growth of data requires innovative technology and more fiber.

High speed migration (HSM) is a technology that helps networks provide more data, enabling managers to face future networks, and providing them with the operational guarantees they need.The requirements for high speed migration (HSM) and how to plan and implement high speed migration (HSM) are described below. 
Why high-speed migration (HSM)? 
Today, data center traffic patterns have changed.Network traffic is mainly east-west traffic (in data centers), which is 10 to 20 times more than north-south traffic (commuting between data centers).The pace of growth in network demand has increased, making it difficult for applications to provide better support.Now, people want to provide better Internet services, but as service demand grows exponentially, it will be difficult to meet those expectations. 
Web services need to do their best to provide content or services, but retailers now measure profits in milliseconds.Stockbrokers have a higher demand for immediate response.Modern sensors may detect customers walking around a store and must respond immediately, such as sending coupons to a customer's phone, at a crucial time.Remote education, medical and even remote surgery are other applications that rely on instantaneous, reliable, ultra-low latency data networks. 
The advent of real-time analytics has changed the way people think about data centers.Traditionally, data center managers have focused on the normal running time of the network, ensuring that services are running and that they are safe.Most of the data center is regarded as a kind of overhead, but as the data become the new currency and real-time applications, driving the demand for more low latency, well-run data center become a competitive advantage.Managers who used to keep their data centers running normally now need to provide higher performance and lower latency to keep their organizations competitive. 
What is high speed migration (HSM)? 
High speed migration (HSM) is a data center network with higher performance and greater capacity.The designed high capacity physical layer infrastructure system will continue to be used for many years, adopt the new infrastructure design method, and look forward to the new high-speed optical system which has not been deployed in the data center.High speed migration (HSM) combines the maximum bandwidth and minimum loss of multimode and single-mode fiber technologies.High speed migration (HSM) platform is a complete product portfolio, all of which support higher speed data center connection, with the highest configuration flexibility:
• interchangeable 8-core, 12-core and 24-core fiber MPO modules support any application without forcing administrators to reconfigure their fiber trunks. 
• ultra-low loss single-mode and multimode fiber maximizes the cost budget and life cycle of existing infrastructure. 
•OM5 broadband multimode fiber can realize 100Gbps and higher distance duplex transmission. 
Successful strategy
The basic challenge for data center managers is to make decisions about today's changes to support different types of optical fiber, protocols and future distances.They must adopt an infrastructure that is flexible enough to control costs.Here are some important strategies. 
Know the options and know your goals
The enterprise needs to have a good understanding of the distance and type of fiber it is using, and how much bandwidth it needs.Such as:
• does the enterprise have a small data center that USES point-to-point wiring, or does it need to reconfigure and test points? 
• what capacity and expected growth curve are required? 
• what network speed (25,40, or 50 gigabits) should be required, and 100 and 400 gigabits? 
There are many ways to achieve future network speed.Multimode fiber (MMF) has recently made innovative progress.For example, the OM5(multimode) fiber has four times the capacity of the OM4 fiber, while maintaining traditional compatibility.When using the OM5 MMF, the new optical transceiver allows transmission at a higher speed (100Gbps) over a link distance of more than 400 metres.While maintaining a structured cabling design, supporting higher speeds over longer distances is a challenge. 
Most decisions depend on when a business begins its journey.Just a few years ago, 40 gigabits were considered the next "high-speed" fiber.But now 100Gbps fiber has quickly replaced the technology.The combination of switch technology and optical technology has eliminated the application of 40G optical fiber. 
Understand your cost structure
Measure the cost and benefits of the various options, and then choose the type of fiber and connectivity solutions that meet the enterprise's goals economically and efficiently.The combination of a calculator from a wiring supplier can help with this process. 
Flexibility plan
The design allows companies to choose between 8-core, 12-core, or 24-core fiber bundles to choose the right infrastructure at each step leading to higher bandwidth.For example, if a company has 12 core optical fiber infrastructure, and decided to use only 8 core optical fiber applications (for example 100 GBPS 4 x5 solution), then it should formulate strategies to optimize the use of the optical fiber infrastructure, while maintaining the use of 100%.The design should support various fiber types and growth strategies to match future applications.However, there is no universal solution. 
Combined modularization
Enterprises can choose to accept all kinds of optical fiber panel module, so that with the development of the data center technology and development, it will have a general shell, technicians can simply exchange module in order to improve the data rate.In an ideal world, the wiring and shell are deployed only once, and only the endpoints that need to be changed to move faster. 
Manage current and future infrastructure
The infrastructure management (AIM) tool provides a clear picture of an enterprise's infrastructure, helping it understand capacity and the location of blocking points.In addition to having a healthier, more manageable infrastructure over the long term, this information also makes it easier for businesses to make informed choices and respond quickly to interruptions. 
Understand the migration time framework
If companies desperately need it, but data centres still have to be upgraded to higher speeds, perhaps sooner than people think.Smart choices can help an enterprise get to its destination as quickly as possible, along with its suppliers.In view of the new real-time service needs more data center capacity, enterprise (HSM) high-speed migration path should be ready and waiting for answer call, at the same time ensure support to expand the capacity of optical network applications.Such guarantees simplify planning and migration strategies while leveraging enterprise investments in data center infrastructure.Application guarantees span the entire physical network layer, but also focuses on optical network link assurance support. 
High-speed migration (HSM) paths are inevitable for large organizations, but they should not be a painful and expensive process.Starting with high capacity, the enterprise carefully evaluates the options and draws the migration path using the correct high speed migration (HSM) product.The data center will become a flexible, economic and efficient real-time computing platform, providing enterprises with competitive advantages in this digital age.
