Internet Data Center Network Optimization, Planning & Design

SYSCOM proudly distributes Cisco's data center products and solutions. We provide system integration services and optimization for next-generation data center (IDC) network infrastructure. Our professional Internet data center optimization service is uniquely tailored to your requirements, and SYSCOM uses the best Cisco products and solutions including: Cisco Nexus, UCS, VSS 6500 and others.

Data Center Ethernet

Data center-class switches must support Data Center Ethernet, or DCE, which handles data flow-control classification, Ethernet congestion, load and traffic management, bandwidth management and link aggregation. The following chart provides greater details.


Network Integration

Data centers traditionally have a data network and a storage area network (SAN), but with application integration and network integration inevitably these networks will combine. Recent research in SAN technology has produced FCoE, which encapsulates data packets into Ethernet packets before transmission. The technology is simple, highly efficiency and economical, making this solution very competitive.

Storage equipment manufacturers, network equipment vendors, host manufacturers, and card manufacturers are all investing in further development of FCoE. However it was the introduction of DCE that has made FCoE implementation a reality. Visit the FCoE website at http://www.fcoe.com and http://www.t11.org/fcoe for details.

Scalability

With 10 gigabit Ethernet having reached maturity, 40/100 gigabit Ethernet will soon be released for commercial use. To ensure hardware purchases have a life-span greater than five years, it is more critical than ever to consider hardware scalability. Given that we all want to maximize equipment life while minimizing maintenance costs, at least a 100 gigabit platform is needed. This means each device and each slot must support at least that speed and with full-duplex.

Right now, using a multilevel matrix design, we can already achieve 200 gigabits per slot. It is reasonable that platform designs over 400 gigabits will soon arrive to meet our ever growing demands on bandwidth.


Single physical device divided into logically independent virtual devices

Virtualization

Data center requirements for network virtualization include support for flexible network grouping. This requirement comes in two important parts. One is flexible to allow a physical device to be divided into a number of logically independent virtual devices and the other is to merge physical devices into a logical entity for use as a business service.




Merging physical devices into a single logical virtual device

Virtualization in the data center allows us to achieve allocation of resources such as port allocation and deployment forwarding tables. Resource sharing like sharing of power and forwarding capacity are another two examples. Virtualization also hardens our data centers in a way of reducing single point of failures by distributing risk and servers can co-allocate resources to achieve on-demand virtual data centers. Data Center Operations The importance of Data Center Ethernet becomes clear, however, devices must support at least basic functions to realize a powerful multi-service implementation that does not affect performance. For example:

‧ Quality of Service (QoS)
‧ Access controls and security controls (ACL)
‧ Virtual switch implementations (Virtual Switch)
‧ Network traffic analysis (Netflow)
‧ CPU protection against attack (CoPP)
‧ Application controls and optimization services
‧ Embedded Event Manager (EEM)
