2012 Server Platforms EnableNew Ethernet CapabilitiesNew server platforms coming to market as of March 2012 letEthernet accomplish more than everBandwidth per port doubles with PCI Express 3.0Integrating PCIe3 onto the processor itself reduces latencyWhat Intel calls “Direct Data I/O” changes the I/O paradigmfor serversThe Ethernet controller talks directly with the processor’s last-levelcacheNo longer is Ethernet traffic forced to detour through main memoryon ingress and egressThis new server platform has the I/O headroom to run up to250 Gbps of Ethernet I/O per processorMore than a factor of three more headroom than any precedingserver platformEthernet Storage Forum14

10GbE Brings Remote DataMemory Access (RDMA)Technology To The Data CenterRemote Direct Memory Access (RDMA) is a technology that allows anapplication to transfer data directly to/from the data space of anotherapplication while bypassing the OS kernelPermits low latency data transfers with low packet jitter, low CPU utilization,and traffic segregated into prioritized classesTwo RDMA-over-Ethernet technologies being deployed today over10GbE, iWARP (internet Wide-Area RDMA Protocol) and RoCE (RDMAover Converged Ethernet)High-performance computing (HPC) workloads written to the OpenFabrics Alliance stack for InfiniBand can run on a 10GbE networksupporting either iWARP or RoCEWindows Server 2012 will take advantage of RDMA capabilities tosupport network Microsoft’s file system called “SMB Direct 3.0.”Ethernet Storage Forum16
Ethernet Virtualization For10GbE OverviewMultiple approaches to “carving up” 10GbE ports andassigning the slices to virtual machines have emergedDemand queuingPCI-SIG Single-Root I/O Virtualization (SR-IOV)OEM-driven NIC partitioning: Dell’s NPAR, HP’s Flex-10, IBM’s vNICOEM-driven network virtualization: Cisco’s FEXDemand queuing is supported by Microsoft and VMwareSR-IOV is supported in Linux Xen and KVMMicrosoft has committed to SR-IOV support in 2012VMware is showing it in their ESX 5.1 betaUsers have multiple and increasing choices for Ethernetvirtualization of 10GbE portsEthernet Storage Forum17
