How to plan a future data center network

From the previous analog signal to the current digital signal, no matter what information can be stored digitally. This makes traditional data centers no longer meet user requirements.

On the other hand, the cost control problem is still a very important index in the Enterprise data Center strategy, which has greatly stimulated the manufacturers to develop http://www.aliyun.com/zixun/aggregation/13616.html. > The pace of a new generation of data centers.

From a technical standpoint, a traditional data center consists of a large number of small servers that make up a series of LANs, which eventually make up the entire datacenter through a routing switch device. Under this architecture, the support for network virtualization and server virtualization will be limited and accessed at a low rate due to the wide range of infrastructure. Faced with more and more rich applications, this traditional data center network architecture will inevitably appear increasingly powerless.

Competition among the three countries to compete for data Center architecture

from the recent actions of vendors, it is easy to see that the development of new infrastructure for the new data center has become a trend.

Cisco's Data Center 3.0 solution is built primarily on the enterprise's existing data center architecture, enabling it to use the familiar, trusted resources of an existing enterprise network as a common platform for connecting and supporting servers, storage, applications, and other IT resources.

as Cisco's only competitor in high-end products, Juniper's Cloud Ready data Center architecture poses a threat to Cisco's Datacenter architecture. In the Juniper concept, the traditional data Center architecture era is coming to an end and will be replaced by a cloud based data center network.

HP's latest "No Cisco Devices" Data Center is a solution that fully benefits HP's/3com equipment. The new HP Network product line integrates HP's ProCurve technology with 3COM routers, switches, and VoIP devices. It is only limited to its own integration has not been completed, HP in the current competition has not achieved much advantage.

However, due to product line problems, the struggling vendors are also doing their best to perfect their Achilles heel: Cisco has partnered with EMC and VMware in the Virtual Computing Environment Alliance (VCE Alliance) to improve the storage and virtualization component of the datacenter with the power of EMC and VMware The significance of HP's acquisition of 3Com is the perfection of its own network product line; In an interview with reporters, Juniper's senior executive also made clear that it would forge a strategic alliance with IBM to confront Cisco's threats. Since then, a new "Three Kingdoms War of Supremacy" has been openedCurtain。

How the cloud makes the data center "all ready"

in the interview, Juniper to reporters: from a technical point of view, Cisco Data Center 3.0 network structure is divided into 3 layers, which makes Cisco in the face of traditional 5-tier to 6-tier data center network structure has more advantages to reflect its server virtualization performance. But at the same time, this structure still restricts the development of network virtualization. The Cloudready Datacenter Architecture is no longer limited in virtualization because it is a cloud-based solution and can be very well supported, both for server virtualization and for network virtualization.

When it comes to cloud Ready, it can be "cloud ready" if translated into Chinese. It is easy to see that Juniper was ready to give its mission to end the controversy over the network architecture of the datacenter at the beginning of the design of the architecture.

in Juniper's view, cloud computing has become a new way of delivering and enjoying services on shared networks and it infrastructures. In the past, it hardware and software had to be on the ground to get or make physical settings. After the adoption of cloud computing, the value of hardware and software products will be delivered on demand through the network in the form of services. Now that cloud computing is no longer confined to network service providers and web-based service providers, corporate or public-sector IT organizations are acutely aware that cloud computing has a huge connection to its own internal operations.

Today's IT department can build its own private cloud or implement a resource extension by leveraging a public cloud. We know that enterprise data centers can benefit from the powerful computing model of the public cloud. The valuable experience we gain from cloud computing will help companies dramatically increase the scalability, flexibility, and application services of enterprise data centers, while reducing costs. To get these benefits, businesses need to double-check their networks, which is also the basis for cloud ready data centers.

What will it look like?

through interviews with the user before the reporter we learned that in the eyes of enterprise users, a data center network architecture is valuable, the most important indicator is stability and security two aspects. The cost of upgrading or building new data centers is also a subject of concern to users.

in theory, device consolidation, virtualization, and cloud computing are all good solutions to the problems of users, and the latest solutions from vendors do emphasize this in every respect, but the user's concerns persist in practical applications: regardless of cost, Will the new technology guarantee the data center's foolproof? I'm afraid this is a dead proposition in itself. As technology develops, so do problems and needs. Fortunately, the "knot" is the impetus for the development of new technology manufacturers, perhaps for users, this is what we need the so-calledHealthy development.
