Tips for simplifying your data center cloud Network

"Ethernet is the backbone of cloud computing. "Is this statement too exaggerated?" Really。 Any data center, cloud computing or anything like that depends on the Ethernet network that allows servers, storage systems, and other devices to transmit to and from each other. No network, no data center.


　　


today, the IT department prepares to deploy an internal cloud environment that can significantly assess how the network infrastructure will affect cloud computing capabilities to meet service level agreements (SLAs). Common terminology to describe cloud computing capabilities, such as agility, flexibility, and scalability, are absolutely applicable to the underlying network and related terms.


　　


with that in mind, let's explore how to simplify the private cloud network. You can learn from Intel's recently completed CliffsNotes version of the white Paper.


　　


merge ports and cables


　　


Most cloud environments use a lot of virtualization. So virtualization has been a growing driver for server bandwidth requirements. Today, one can often see eight or more virtualized servers for Gigabit Ethernet (GbE) ports. Of course, this also means a lot of wiring, network adapters and switch ports. Consolidate these GBE connected network connections to several 10,000 Gigabit Ethernet (10GbE) connections, while reducing device costs, reducing the number of possible fault points, and increasing the total bandwidth of the server.


　　


brings data and storage to Ethernet


　　


10GbE Storage technology support, such as iSCSI and Fibre Channel Ethernet (FCoE), supports the need for network consolidation to further integrate into Ethernet storage traffic. This eliminates the need to store specific server adapters and infrastructure equipment. It organizations can consolidate LAN and SAN traffic to a single network or maintain a separate Ethernet based storage network. Either way, they have made it easier and more cost-effective to help servers connect to networked storage systems, reducing device costs and simplifying the network.


　　


maximizes I/O virtualization performance and flexibility


　　


Once you have a unified 10GbE network connection cloud resource, you need to make sure that you effectively use these large pipelines. A physical server can host many virtual machines (VMS). Also, make sure that you have the appropriate balance between bandwidth allocation and these virtual machines. There are different ways to divide a 10GbE port into smaller, virtual pipes, but the ports are not equal. Some of the partitioning methods allow these virtual functions to scale as needed and use the available bandwidth of a Gigabit Ethernet connection, while others assign the static bandwidth of each virtual function, limit elasticity, and unused capacity in exceptional cases.


　　


solutions that enable multiple management programs


　　


this may be because most cloud deployments consist of hardware and software, including management programs from multiple vendors. Different management programs take different approaches to I/O virtualization and it is important to optimize I/O performance for different software platforms and network solutions, and inconsistent throughput in heterogeneous environments can lead to bottlenecks that affect the services provided. You can avoid this in most major management programs by using an Ethernet adapter, improve network performance, support machine device queues (VMDQ), and single I/O Virtualization (IOV).


　　


Service quality using Multi-Tenant network


　　


is like a public cloud, a private cloud that provides services to many different customers, ranging from a business unit within the enterprise to customers across the enterprise, and they all have cloud performance expectations. Quality service (QoS) helps ensure that customer requirements are met. Technology enables QoS on the network and on a single physical server. QoS is the data center bridging (DCB) between devices on the network, setting the criteria for how bandwidth is allocated to specific traffic, and how to implement these policies. In the traffic between the server's virtual machines, QoS can be controlled by hardware or software, depending on the hypervisor. When you select a network adapter for your server, these types of QoS support should be considered.
