Storage with Intense Network Growth and the Rise of RoCE

February 4th, 2015

On January 4 and 5, the Entertainment Storage Alliances held the 14th annual Storage Visions conference in Las Vegas, highlighting advances in storage technologies utilized in consumer electronics, the media and entertainment industries. The theme of Storage Visions 2015 was Storage with Intense Network Growth (SWING), which was very appropriate given the explosions going on in both data storage and networking.

While the primary focus of Storage Visions is storage technologies, this year’s theme acknowledges the corollary between storage growth and network growth. Therefore, among the many sessions offered on increased capacity and higher performance, the storage networking session was specifically designed to educate the audience on advances in network technology – “Speed is the Need: High Performance Data Center Fabrics to Speed Networking.”

More pressure is being put on the data center network from a variety sources, including continued growth in enterprise application transactions, new sources of data (aka, big data) and the growth in streaming video and emergence of 4K video. According to Cisco, global IP data center traffic will grow 23% annually to 8.7 zettabytes by 2018. Three quarters of this traffic will be inter-data center, or traffic between servers (East-West) or between servers and storage (North-South). Given this, data centers need to factor in technologies designed to optimize data center traffic.

Storage administrators have always placed emphasis on two important metrics, I/O operations per second (IOPS) and throughput, to measure the ability of the network to server storage devices. Lately, a third metric, latency, has become equally important. When balanced with the IOPS and throughput, low latency technologies can bring dramatic benefits to storage.
At this year’s Storage Visions conference, I was asked to sit on a panel discussing the benefits of Remote Direct Memory Access (RDMA) for storage traffic. I specifically called out the benefits of RDMA over Converged Ethernet (RoCE). Joining me on the panel were representatives from Mellanox, speaking about InfiniBand, and Chelsio, speaking about iWARP. The storage-focused audience showed real interest in the topic and asked a number of insightful questions about RDMA benefits for their storage implementations.

RoCE in particular will bring specific benefits to data center storage environments. As the purest implementation of the InfiniBand specification in the Ethernet environment, it has the ability to provide the lowest latency for storage. In addition, it capitalizes on the converged Ethernet standards defined in the IEEE 802.1 standards for Ethernet, include Congestion Management, Enhanced Transmission Selection and Priority Flow Control, which collectively allow for lossless transmission, bandwidth allocation and quality of service. With the introduction of RoCEv2 in September 2014, the technology moves from support for a (flat) Layer 2 network to become a routable protocol supporting Layer 3 networks, allowing for use in distributed storage environments.
Ultimately, what customers need for optimal Ethernet-based storage is technology which will balance between IOPS, throughput, and latency while allowing for flexible storage placement in their network. RoCE addresses all of these needs and is becoming widely available in popular server and storage offerings.

The IBTA Celebrates Its 15th Anniversary

December 15th, 2014

Since 1999, the IBTA has worked to further the InfiniBand specification in order to provide the IT industry with an advanced fabric architecture that transmits large amounts of data between data centers around the globe. This year, the IBTA is celebrating 15 years of growth and success.

In its mission to unite the IT industry, the IBTA has welcomed an array of distinguished members including Cray, Microsoft, Oracle and QLogic. The IBTA now boasts over 50 member companies all dedicated to furthering the InfiniBand specification.

The continued growth of the IBTA reflects the IT industry’s dedication to the advancement of InfiniBand. Many IBTA member companies are developing products incorporating InfiniBand technology, including FDR, which has proven to be the fastest growing generation of InfiniBand technology: FDR adoption grew 76 percent year over year from 80 systems in 2013 to 141 systems in 2014. Most recently, the Top500 list announced that 225 of the world’s most powerful computers chose InfiniBand as their interconnect device in 2014.

2014 also marked the release of RoCEv2. RoCEv2 is an extension of the original RoCE specification announced in 2010 that brought benefits of Remote Direct Memory Access (RDMA) I/O architecture to Ethernet-based networks. The updated specification addresses the needs of today’s evolving enterprise data centers by enabling routing across Layer 3 networks. By extending RoCE to allow Layer 3 routing, the specification can provide better traffic isolation and enables hyperscale data center deployments.

Below is a timeline that further illustrates the IBTA’s advancements over the past 15 years that have helped to bring InfiniBand technology to the forefront of the interconnect industry.

IBTA Announces New RoCE Specification

September 16th, 2014

Big news! The IBTA today announced the updated specification for Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE), RoCEv2. This is a huge development and one that will expand RoCE’s adoption.

The benefits of the first RoCE spec released in 2010 were many:

  • Low latency and CPU overhead (eliminated the multiple data copies inside the server)
  • High network utilization
  • Support for message passing, sockets and storage protocols
  • Supported by all major operating systems

RoCEv2 extends the original RoCE specification by enabling routing across Layer 3 networks and as a result provides better isolation and enables hyperscale data center deployments. This addresses the needs of today’s evolving data centers which require more efficient data movement over a variety of network topologies.

With a number of vendors including Dell and Zadara Storage recently adopting RoCE, this new specification comes at the perfect time. Major cloud providers and Web 2.0 companies are also adopting RoCE in order to combat the challenges of running compute intensive applications and processing massive amounts of data in hyperscale networking environments.

Representatives from IBTA member companies including Emulex, IBM, Mellanox, Microsoft and Software Forge, Inc. participated in the development of this new standard, which will help enterprises to more widely adopt RoCE and improve infrastructure efficiency.

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.

ISC’14 Insights

July 10th, 2014

With ISC’14 in June recently concluded, the IBTA would like to highlight some of our members’ biggest announcements, key takeaways from the event and give an overall look at the impact of InfiniBand in the supercomputing world.

Event Overview

Overall the event was a huge success, showcasing demonstrations and facilitating many major announcements in the supercomputing industry. As always, the event attracted supercomputing leaders from around the world, who provided thought leadership and knowledge to thousands of attendees and exhibitors.

Chris Pfistner, senior director of marketing at Finisar, noted, “ISC in Leipzig is a vibrant show!  Between SC in the US and ISC focused on Europe and Asia, the global Super Computing community is well represented, and the space is on fire with several players unveiling new systems and showing great interest in Finisar’s EDR AOC demo – 100G links are becoming reality.”

The ISC YouTube channel is another great resource for checking out all that happened at ISC’14!

Major InfiniBand Announcements

During the event, the updated TOP500 list was released, showing that InfiniBand is the most used interconnect by the world’s fastest supercomputers and represents 44.4 percent of the TOP500 at 222 systems. InfiniBand also connects the top 17 most efficient systems and 50 percent of Petaflop-capable systems on the list. Fourteen Data Rate (FDR) InfiniBand, delivering 56Gb/s per link to address the bandwidth demand by high performance clustered computing, drives the systems with the highest utilization on the TOP500, achieving a record breaking 99.8 percent system efficiency.

IBTA member Finisar showcased a live demonstration of its next generation 100Gb/s Quadwire Active Optical Cable (AOC). This optical interconnect runs four parallel lanes of 25Gb/s to enable the next generation of InfiniBand EDR-based supercomputers. Leveraging Finisar’s patented fiber optic technology, the AOC will allow the transmission of high-speed data with enhanced signal integrity, higher density, lower power consumption, smaller bend radius and longer reach than traditional copper solutions.

Mellanox Technologies, also an IBTA member, unveiled the world’s first 100Gb/s EDR InfiniBand switch at ISC’14. The 100Gb/s switch expands InfiniBand’s bandwidth and provides increased switching capacity while lowering latency and power consumption. This solution, called Switch-IB, will enable application managers to use the power of data, delivering 5.4 billion packets per second, and making it an excellent solution for HPC, cloud, Web 2.0, database and storage centers.

In other news, Applied Micro teamed up with Nvidia to promote the X-Gene and Tesla duo. The Ethernet ports on the X-Gene 2 chip will be able to run RDMA over Converged Ethernet (RoCE), which brings the low latency of RDMA to the Ethernet protocol. This will make the chip not only suitable for HPC workloads that are latency sensitive, but also for database, storage, and transaction processing workloads in enterprise datacenters that also demand low latency. In tandem, Mellanox announced that their 56Gb/s InfiniBand products will now be optimized for the X-Gene platform.

To sum it all up, here are the IBTA’s key takeaways from the event:

· 100Gb/s is becoming a reality

· InfiniBand is leading the way with EDR taking center stage

· The industry is taking full advantage today of the performance and efficiency benefits of FDR and RoCE

ISC’14 was a great forum for knowledge sharing and big industry announcements. All of us at the IBTA look forward to seeing more InfiniBand news and discussions in the coming months.
