Recent Trends toward RoCE Adoption

September 2nd, 2014

The RoCE specification was released back in April, 2010 to address the need for efficient RDMA in end to end Ethernet networks. With the increase in enterprise data traffic and the emergence of hyperscale infrastructure, the need for efficient networking continues to grow.  Here are the latest examples of RoCE in the field.

RoCE Accelerates Microsoft Windows Azure

Albert Greenberg, an architect with IBTA member Microsoft, describes in his keynote address to the Open Network Summit this year how they are using RoCE in their storage offering.  RoCE over 40GbE enabled line-rate performance with zero CPU usage.  At the same time they were able to use less CPUs than would otherwise be needed.

RoCE Used in Dell Fluid Cache for SAN pool

Dell’s Fluid Cache for SAN accelerates applications requiring high data I/O. The servers in this pool are connected to each other by RoCE NICs, making use of the technology to quickly move data between the nodes without facing bottlenecks from the slow operating system kernel.

RoCE Can Do What Ethernet Alone Cannot

IBTA member Applied Micro is continuing to roll out its X-Gene family of 64-bit processors. These processors support RoCE, giving 10GbE some of the low-latency capabilities that used to only be available to InfiniBand. The decrease in latency for Ethernet means transaction latencies also decrease, better positioning the X-Gene family to make a difference in modern workloads.

RoCE Provides Exceptional Performance for Storage Solutions

Zadara Storage announced a new high performance STaaS solution offer for private clouds that uses an Ethernet transport mechanism for exceptional performance at reduced costs. Developed as a collaboration with IBTA member Mellanox Technologies, this solution boosts application performance using the iSCSI Extensions for RDMA (iSER) over RoCE, delivering substantially improved latency and throughput and therefore delivering cost savings and converged enterprise storage for private clouds of all sizes.

RoCE Helps Data Centers Account for New Technology for the Cloud

With the huge acceleration of data centers to the cloud, low latency is becoming increasingly important to avoid bottlenecks and incorporate new technologies seamlessly. RoCE, says SYS-CON Media’s Barbara Porter, is one way to plan for the barrage of new technology that’s coming our way, and to reduce latency overall in the cloud.

Emulex Joins the InfiniBand Trade Association

October 30th, 2013

Emulex is proud to be a new member of the IBTA.  The IBTA has a great history of furthering the InfiniBand and RDMA over Converged Ethernet (RoCE) specifications, developing an active solution ecosystem and building market momentum around technologies with strong value propositions.  We are excited to be a voting member on the Organization’s Steering Committee and look forward tocontributing to relevant technical and marketing working groups, as well as participating in IBTA-sponsored Plugfests and other interoperability activities.

Why the IBTA?

Through our experience in building high performance, large-scale, mission critical networks we understand the benefits of RDMA.  Since its original implementation as part of InfiniBand back in 1999, RDMA has a well-proven track record of delivering better application performance, reduced CPU overhead and increased bandwidth efficiency in demanding computing environments.

Due to increased adoption of technologies such as cloud computing, big data analytics, virtualization and mobile computing, more and more commercial IT infrastructures are starting to run into the same challenges that supercomputing was forced to confront around performance bottlenecks, resource utilization and moving large data sets.  In other words, data centers supporting the Fortune 2000, vertical applications for media and entertainment or life sciences, telecommunications and cloud service providers are starting to look a lot more like the data centers at research institutions or systems on the TOP500 .  Thus, with the advent of RoCE, we see an opportunity to bring the benefits of RDMA that have been well-proven in high performance computing (HPC) markets to the mainstream commercial markets.

RoCE is a key enabling technology for converging data center infrastructure and enabling application centric I/O across a broad spectrum of requirements.  From supercomputing to share drives, RDMA deliveries broad based benefits for fundamentally more efficient network communications.  Emulex has a data center vision to connect, monitor and manage on a single unified fabric.  We are looking forward to supporting the IBTA, contributing to the advancement of RoCE and helping to bring RDMA to mainstream markets.

The changing data center landscape

June 4th, 2009

By Jeff Boles, Taneja Group

Recently, Taneja Group published what has become an annual report reviewing the state of InfiniBand in mainstream IT. Once again, the landscape has evolved in interesting ways this year, with virtual infrastructure and cloud computing being several of the forces driving InfiniBand adoption in the enterprise data center. Long story short, InfiniBand has proved itself as a capable platform for continued evolution, and vendors with products in this space have long ago figured out how to make the fabric into a platform. While us bleeding edge technologists speculate about what infrastructure as a service is going to look like, the most common names in InfiniBand have been turning the infrastructure fabric into a service enabled platform. Slightly different twists, as you will soon learn inside the report.
