Resolve Security and Throughput HPC Cloud ChallengesSARA identified the I/O virtualization support in Intel® Ethernet 10 Gigabit Converged Network Adapters as the ideal means of meeting both security and throughput requirements for its high-performance cloud computing network infrastructure.To provide high-performance computing (HPC) resources for research, Netherlands-based SARA must maintain very high throughput for message-passing interface (MPI) workloads between virtual machines (VMs) in a cluster environment. InfiniBand*, the conventional interconnect choice for these types of clusters, did not support the required combination of security and performance in the cloud environment. SARA resolved that issue using Intel® Ethernet 10 Gigabit Converged Network Adapters.Challenge• Provide a high-performance interconnect between VMs to support MPI workloads in a cloud infrastructure, while meeting the stringent security standards required to protect valuable intellectual property and other sensitive data.• Overcome security limitations of basic InfiniBand in the cloud, without adding security layers such as iptables, ebtables, and VLAN tagging that impose severe TCP/IP overhead and reduce throughput to unacceptable levels, due to the limitations of IP over InfiniBand.Solution• Intel Ethernet 10 Gigabit Converged Network Adapters incorporate I/O virtualization with Intel® Virtualization Technology (Intel® VT) for Connectivity (Intel® VT-c) that enables lower CPU utilization and improved networking and I/O throughput.• Data protection for the cloud is provided by PCI-SIG Single Root I/O Virtualization (SR-IOV), a key component of Intel VT-c, which helps ensure that data traffic within one VM cannot be accessed by other VMs, and other platform features such as Intel® Trusted Execution Technology (Intel® TXT), which ensures a trusted launch environment.Read the full Resolve Security and Throughput HPC Cloud Challenges case study: http://www.intel.com/content/www/us/en/network-adapters/10-gigabit-network-adapters/10gbe-hpc-sara-study.html
