CONNECTIVITY - SOLUTIONS BRIEF Optimize OpenStack Networking with Emulex Optimize Network Performance and Reduce I/O Ports with Universal Multi-Channel Switch agnostic and offered through major OEMs OpenStack is quickly becoming the preferred open source choice for building private clouds and Infrastructure as a Service (IaaS) offerings. Customers in many industries, including cloud services, financial services and telecommunications are leveraging the framework to build their infrastructure. Many companies offer OpenStack distributions, including Dell, HP, Mirantis, Oracle, Red Hat and VMware, allowing companies the flexibility to package their OpenStack implementation with hardware or virtualization software, or work with an independent company such as Mirantis and keep ultimate flexibility for their infrastructure. Simplified management using Emulex OneCommand Manager or VMware vRealize framework As enterprises and cloud providers implement OpenStack to build these private cloud and IaaS offerings they are looking for solutions which will: Emulex Advantages ■■ ■■ ■■ ■■ ■■ ■■ Reduced cabling and I/O port requirements using network convergence Improved utilization of server and network resources Optimal network performance with Quality of Service (QoS) Pervasive in-box support with all major hypervisors and operating systems 1.Optimize cost of networking I/O 2.Improve performance of priority traffic 3.Enhance traffic isolation 4.Ease management of I/O resource OpenStack Implementation with Emulex OCe14000 using UMC Emulex Universal Multi-Channel (UMC) allows each NIC to be carved into 16 separate channels with isolated transmit and receive queues and individual MAC addresses, providing each VLAN a separate physical function. Major OEMs deliver Emulex UMC capabilities through their own networking offerings, for example Dell Network Partitioning (NPAR), HP FlexFabric, and IBM Virtual Fabric, which enables allocation of separate physical functions for VM migration, console management, iSCSI and NFS storage, and network traffic for individual VMs. Cost optimization through port consolidation and switch independence Emulex UMC enables multiple OpenStack functions to be consolidated onto fewer I/O ports. Combining ports minimizes the I/O sprawl as customers can easily support the management, compute, storage and networking functions of OpenStack on fewer ports and also ensures each port is fully utilized in order to take full advantages of I/O resources. In addition, because Emulex UMC is switch agnostic, it will work in any 10 or 40Gb Ethernet environment, allowing customers to build upon their existing infrastructure. Improved performance with QoS Using Emulex UMC, each OpenStack function can be assigned a minimum and maximum bandwidth. This allows more important functions, such as compute or storage, to have the network capacity they need to continue performing even under heavy network loads. Bandwidth can easily be reallocated as necessary given changing workload conditions. This separation ensures that priority traffic has a minimum bandwidth allocation and that independent channels are not impacted due to network and port congestion. Traffic isolation improves availability and security UMC allows different VLANs to be assigned to different physical functions. The hardware enforced channels provide stronger isolation between networks and traffic types. This configuration enables higher availability in case of VLAN failure and provides additional security should the network be compromised. Simplified management Emulex UMC reduces the number of devices and simplifies traffic management. It is easily administered through OneCommand Manager, or through VMware vRealize, using the OneCommand Manager web client. This ensures simplified management and configurability for Emulex UMC in an OpenStack environment. Conclusion Data centers using OpenStack to build private or public cloud offerings need to consider technologies which will optimize cost, improve performance, isolate traffic and simplify management of I/O. The Emulex OCe14000 series enables these organizations to optimize their OpenStack network using Emulex Universal-Multi-Channel.
