Abstract InfiniBand Technology Overview The InfiniBand architecture brings fabric consolidation to the data center. Storage networking can concurrently run with clustering, communication and management fabrics over the same infrastructure, preserving the behavior of multiple fabrics. The tutorial provides an overview of the InfiniBand architecture including discussion of High Speed – Low Latency, Channel I/O, QoS scheduling, partitioning, high availability and protocol offload. InfiniBand based storage protocols, iSER (iSCSI RDMA Protocol), NFS over RDMA and SCSI RDMA Protocol (SRP), are introduced and compared with alternative storage protocols, such as iSCSI and FCP. The tutorial further enumerates value-add features that the InfiniBand brings to clustered storage, such as atomic operations and end to end data integrity. Learning Objectives: Understand the InfiniBand architecture and feature set. Understand the benefits of InfiniBand for networked storage. Understand the standard InfiniBand storage protocols.

Click to view this week's ad screen [Design View / Design Solution] Break Through The TCP/IP Bottleneck With iWARP Using a high-bandwidth, low-latency network solution in the same network infrastructure provides good insurance for generation networks. Sweta Bhatt, Prashant Patel ED Online ID #21970 October 22, 2009 Copyright © 2006 Penton Media, Inc., All rights reserved. Printing of this document is for personal use only. Reprints T he online economy, particularly e-business, entertainment, and collaboration, continues to dramatically and rapidly increase the amount of Internet traffic to and from enterprise servers. Most of this data is going through the transmission control protocol/Internet protocol (TCP/IP) stack and Ethernet controllers. As a result, Ethernet controllers are experiencing heavy network traffic, which requires more system resources to process network packets. The CPU load increases linearly as a function of network packets processed, diminishing the CPU’s availability for other applications. Because the TCP/IP consumes a significant amount of the host CPU processing cycles, a heavy TCP/IP load may leave few system resources available for other applications. Techniques for reducing the demand on the CPU and lowering the system bottleneck, though, are available. iWARP SOLUTIONS Although researchers have proposed many mechanisms and theories for parallel systems, only a few have resulted in working computing platforms. One of the latest to enter the scene is the Internet Wide Area RDMA Protocol, or iWARP, a joint project by Carnegie Mellon University Corp. -

Iser: Frequently Asked Questions
iSER: Frequently Asked Questions The iSCSI Extensions for RDMA or iSER protocol is an iSCSI translation layer for operation over RDMA transports, such as InfiniBand or iWARP/Ethernet. The most unexpected fact about iSER is that, despite its name, it is not compatible with iSCSI and does not interoperate with the large iSCSI installed base. This FAQ clarifies this and other questions that are associated with this protocol. Is iSER compatible with iSCSI? NO – iSER is effectively an emulation layer that translates iSCSI to RDMA transactions that cannot be understood by non-RDMA peers: iSER transports iSCSI control messages in RDMA SEND/RECV commands and iSCSI payload in RDMA READ/WRITE operations, altering the wire formats in the process. The following figure shows the protocol layering for iSCSI vs. iSER, revealing the number of additional layers introduced by the latter, and the resulting incompatibility on the wire. Figure 1 – iSCSI and iSER Protocol Layers Does iSER interoperate with iSCSI peers? NO – an iSER client or server can only communicate with other iSER end nodes. Interoperating in this case means disabling iSER extensions, and losing offload support and all performance benefits. Does iSER work with software peers? NO – iSER requires RDMA enabled hardware on both ends of the communication. In contrast, iSCSI hardware implementations are not only fully interoperable with software peers, but also preserve all the local performance benefits regardless of the peer type. Does iSER provide good performance? MAYBE – iSER can provide improved efficiencies at large I/O sizes, but benchmarks show degraded performance at small I/O sizes due to the additional overheads introduced. -
Iscsi Will Still Be Widely Deployed for at Least the Next Few Years, but Its Growth Prospects Beyond That Are Very Unclear
Widespread use and support mean iSCSI will still be widely deployed for at least the next few years, but its growth prospects beyond that are very unclear. By John F. Kim, Chair, SNIA Networking Storage Forum. What is iSCSI? iSCSI is a block storage protocol for storage networking. It stands for “Internet Small Computer Systems Interface” and runs the very common SCSI storage protocol across a network connection which is usually Ethernet with TCP. You can read more about iSCSI at the “What Is” section of the SNIA website. (The SCSI storage protocol is also used to access block storage as part of the SAS, SRP, and FCP protocols, which run over various physical connections.) Originally, the SCSI protocol was used only for local storage, meaning individual disk drives or direct-attached storage (DAS). Then around 1993, Fibre Channel came along and enabled SCSI to run the Fibre Channel Protocol (FCP) on top of a Fibre Channel Storage Area Network (FC-SAN). iSCSI was submitted as a standard in 2000 and grew in popularity as it was supported by more operating systems, first requiring dedicated iSCSI HBAs but later using a software iSCSI initiator that ran on top of any type of Ethernet NIC. The dedicated iSCSI HBAs gave iSCSI faster performance that was closer to Fibre Channel performance at the time, while the software iSCSI initiator made it easy to use iSCSI from many servers without buying special HBAs for each server. Probably the biggest boost to iSCSI adoption was when Microsoft Windows Server 2008 included a software iSCSI initiator 1/6 (starting in 2008, of course). -
Designing High-Performance and Scalable Clustered Network Attached Storage with Infiniband
DESIGNING HIGH-PERFORMANCE AND SCALABLE CLUSTERED NETWORK ATTACHED STORAGE WITH INFINIBAND DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Ranjit Noronha, MS * * * * * The Ohio State University 2008 Dissertation Committee: Approved by Dhabaleswar K. Panda, Adviser Ponnuswammy Sadayappan Adviser Feng Qin Graduate Program in Computer Science and Engineering c Copyright by Ranjit Noronha 2008 ABSTRACT The Internet age has exponentially increased the volume of digital media that is being shared and distributed. Broadband Internet has made technologies such as high quality streaming video on demand possible. Large scale supercomputers also consume and cre- ate huge quantities of data. This media and data must be stored, cataloged and retrieved with high-performance. Researching high-performance storage subsystems to meet the I/O demands of applications in modern scenarios is crucial. Advances in microprocessor technology have given rise to relatively cheap off-the-shelf hardware that may be put together as personal computers as well as servers. The servers may be connected together by networking technology to create farms or clusters of work- stations (COW). The evolution of COWs has significantly reduced the cost of ownership of high-performance clusters and has allowed users to build fairly large scale machines based on commodity server hardware. As COWs have evolved, networking technologies like InfiniBand and 10 Gigabit Eth- ernet have also evolved. These networking technologies not only give lower end-to-end latencies, but also allow for better messaging throughput between the nodes. This allows us to connect the clusters with high-performance interconnects at a relatively lower cost.
