Top Three Network Considerations for Large Scale Cloud Deployments

The rapid pace of change in data and business requirements is the biggest challenge when deploying a large scale cloud.  It is no longer acceptable to spend years designing infrastructure and developing applications capable to cope with data and users at scale. Applications need to be developed in a much more agile manner, but in such a way that allows dynamic reallocation of infrastructure to meet changing requirements.

Choosing an architecture that can scale is critical. Traditional “scale-up” technologies are too expensive and can ultimately limit growth as data volumes grow. Trying to accommodate data growth without proper architectural design, results in un-needed infrastructure complexity and cost.

The most challenging task for the cloud operator in a modern cloud data center supporting thousands or even hundreds-of-thousands of hosts is scaling and automating network services.  Fortunately, server virtualization has enabled automation of routine tasks – reducing the cost and time required to deploy a new application from weeks to minutes.   Yet, reconfiguring the network for a new or migrated virtual workload can take days and cost thousands of dollars.

To solve these problems, you need to think differently about your data center strategy.  Here are three technology innovations that will help data center architects design a more efficient and cost-effective cloud:

1.  Overlay Networks

Overlay network technologies such as VXLAN and NVGRE, make the network as agile and dynamic as other parts of the cloud infrastructure. These technologies enable automated network segment provisioning for cloud workloads, resulting in a dramatic increase in cloud resource utilization.
Overlay networks provide for ultimate network flexibility and scalability and the possibility to:

  • Combine workloads within pods
  • Move workloads across L2 domains and L3 boundaries easily and seamlessly
  • Integrate advanced firewall appliances and network security platform seamlessly

Mellanox Boosts SDN and Open Source with New Switch Software

Authored by:  Amir Sheffer, Sr. Product Manager

This week we reinforced our commitment to Open Ethernet, open source and Software Defined Networking (SDN). With the latest software package for our Ethernet switches. Mellanox has added support for two widely used tools—OpenFlow and Puppet, among other important features.

The introduction of the new functionality allows users to move towards using more SDN and automation in their data centers. Compared to custom CLI scripts, OpenFlow and Puppet enable customers to control and monitor switches in a unified, centralized manner, thus simplifying the overall network management effort, with less time and cost. Forwarding rules, policies and configurations can be set once then applied to many switches across the network, automatically.

Flexible OpenFlow Support

Mellanox Ethernet switches can now operate in OpenFlow hybrid switch mode, and expose both an OpenFlow forwarding pipeline and a locally-managed switching and routing pipeline. The OpenFlow forwarding pipeline utilizes thousands of processing rules (or flows), the highest number in the industry.

Switches interface with an OpenFlow controller using an integrated OpenFlow agent that allows direct access to the SwitchX®-2-based switch forwarding and routing planes.  The hybrid switch model provides the most robust, easy-to-use and efficient implementation, as it can forward a packet according to the OpenFlow configuration, when such a match is found, or can handle it by its forwarding/routing pipeline, according to the locally-managed switch control applications.

This allows customers to implement OpenFlow rules where they provide the most benefit without needing to move every switch completely to OpenFlow-only management. By processing non-OpenFlow data through its local management plane and leveraging the local forwarding pipeline, the hybrid switch increases network performance and efficiency, through faster processing of new flows as well as lower load on the controllers.

This is much more flexible than another OpenFlow switch mode called OpenFlow-only. This mode does not allow the switch to have a local control plane, so each and every flow must be configured by the OpenFlow controller, which in turn creates high load on the controllers, resulting in high latency and low efficiency.

Open-Source Automation via Puppet

Further enhancing the openness of our switches and the standardization of configuration, Mellanox switches now integrate the Puppet™ automation software agent. Puppet provides an open-source-based standard interface for device configuration and management. Tasks, such as software downloads, port configurations, and VLAN management can be managed automatically according to defined policies.  Mellanox’s implementation of the Puppet agent is Netdev, which is a vendor-neutral network abstraction framework. Mellanox Netdev has been submitted to the DevOps community and can be downloaded for free.

Customers have the choice to manage our switches using a CLI, Web GUI, SNMP, XML, and now Puppet and OpenFlow. This allows the flexibility to design the easiest and most scalable management solution for each environment, and expands Mellanox’s commitment to open source.

Mellanox is involved and contributes to other open source projects, such as OpenStackONIE, Quagga and others, and already contributed certain adaptor applications to the open source community. Mellanox is also a leading member and contributor of the Open Compute Project, where it provides NICs, switches and software.

Accelerating Red Hat’s new OpenStack cloud platform with Mellanox Interconnect

Red Hat Enterprise Linux OpenStack Platform is a new leading Infrastructure-as-a-Service (IaaS) open-source solution for building and deploying cloud-enabled workloads. This new cloud platform gives customers the agility to scale and quickly meet customer demands without compromising on availability, security, or performance.

Red Hat built an industry leading certification program for their OpenStack platform. By achieving this technology certification, partners can assure customers that their solutions have been validated with Red Hat OpenStack technology.  Anyone who earns this new certification will be able to show that they can accomplish the following tasks:

•             Install and configure Red Hat Enterprise Linux OpenStack Platform.

•             Manage users, projects, flavors, and rules.

•             Configure and manage images.

•             Add compute nodes.

•             Manage storage using Swift and Cinder.

 

Mellanox is listed in the Red Hat marketplace as a certified Hardware partner for Networking (Neutron) and Block Storage (Cinder) services. This ensures that Mellanox ConnectX-3 hardware was tested, certified, and now supported with Red Hat OpenStack technology.

Mellanox Technologies offers seamless integration between its products and Red Hat OpenStack services and provides unique functionality that includes application and storage acceleration, network provisioning, automation, hardware-based security, and isolation. Furthermore, using Mellanox interconnect products allows cloud providers to save significant capital and operational expenses through network and I/O consolidation and by increasing the number of virtual machines (VMs) per server.

With Mellanox ConnectX-3 card and OpenStack plugins, customers will benefit from superior performance and native integration with Neutron:

 

Mellanox OpenStack solution extends the Cinder project by adding iSCSI running over RDMA (iSER). Leveraging RDMA, Mellanox OpenStack delivers 5x better data throughput (for example, increasing from 1GB/s to 5GB/s) and requires up to 80% less CPU utilization.

Mellanox ConnectX-3 adapters equipped with onboard embedded switch (eSwitch) are capable of performing layer-2 switching for the different VMs running on the server. Using the eSwitch will gain higher performance levels in addition to security and QoS. The eSwitch configuration is transparent to the Red Hat Enterprise Linux OpenStack Platform administrator by using the Mellanox neutron plugin. By implementing a technology called SR-IOV (Single Root IO Virtualization) and running RDMA over eSwitch, we were able to show a dramatic difference (x20) compared to when using para-virtualized vNIC running a TCP stream connectivity.

The Promise of an End-To-End SDN Solution, can it be done?

Written By: Eli Karpilovski, Manager, Cloud Market Development

 

The new open source cloud orchestration platform called OpenStack is the promise of flexible network virtualization, and network overlays are looking closer than ever. The vision of this platform is to enable the on-demand creation of many distinct networks on top of one underlying physical infrastructure in the cloud environment. The platform will support automated provisioning and management of large groups of virtual machines or compute resources, including extensive monitoring in the cloud.

 

There is still a lot of work to be done, as there are many concerns around the efficiency and simplicity of the management solution for the compute and storage resources. A mature solution will need to incorporate different approaches to interact within the intra-server provisioning, QoS and vNIC management. For example, by leaning on local network adapters that are capable of managing the requests utilizing OpenFlow protocol, or by using a more standard approach which is managed by the switch. Using only one method, might create performance and efficiency penalties.

RDMA – Cloud providers “secret sauce”

Written By: Eli Karpilovski, Manager, Cloud Market Development

 

With expansive growth expected in the cloud-computing market, some researches expects the market will grow from $70.1 billion in 2012 to $158.8 billion in 2014 – cloud service providers must find ways to provide increasingly sustainable performance. At the same time, they must accommodate an increasing number of internet users, whose expectations about improved and consistent response times are growing.

 

However, service providers cannot increase performance if the corresponding cost also rises. What these providers need is a way to deliver low latency, fast response, and increasing performance while minimizing the cost of the network.

 

One good example to accomplish that is RDMA, Traditionally centralized storage was either slow or created bottlenecks and deemphasized the need for fast storage networks. With the advent of fast solid state devices, we are seeing a need for a VERY fast and converged network, to leverage the capabilities that is been offered, in particular, we are starting to see cloud arch using RDMA based storage appliances to accelerate access storage time, reduce latency and achieve the best CPU utilization on the end point.

 

To learn more about the usage of RDMA in providing cloud infrastructure requirements for meeting performance, availability and agility needs, now and in the future check the following link.
