IBM Research - Haifa

Advanced System Technologies

The Advanced System Technologies division at the Haifa Research Lab is one of IBM's technology innovation centers. Its mission is to develop leading-edge technologies for IBM server, networking and storage product lines and IBM Services business units. The division is particularly strong in the areas of system software and architecture, and system design and optimization tools. This is the homepage for the division; our departmental pages provide additional details on our R&D activities.

We are in particularly interested in the field of Cloud Computing, and we put a lot of effort on developing technologies to support IBM Cloud Computing portfolio. In particular, our work focuses on the areas of resource management and virtualization, which are the primary enabling technologies of Cloud Computing. Our division's activities in these areas influence a wide range of IBM system products, including IBM's PureSystems, IBM's System x (with a focus on blade servers), IBM's System p, IBM System z, IBM Tivoli (focusing on cloud management), and more.

Our work in the area of storage systems focuses on developing new functions for data protection and availability, long-term data preservation, and storage optimization. A special focus area of our team is storage support for Cloud Computing. In this project, we investigate the architectural challenges of designing a highly scalable and cost-effective storage infrastructure, allowing to easily store and access data objects, and mobilize them across the Cloud. Our work has led to the development of a unique technology ("Web Storage Service") that has been highlighted in IBM's statement of direction from June 4th, 2012, and released on June 16th, 2013:

"Storwize V7000 Unified Cloud Data Management Interface (CDMI) provides CDMI object storage support for cloud-friendly, industry-standard implementation leveraging Storwize V7000 advantages for one of the fastest growing uses of storage." (Quote from IBM release notes)

We are strongly engaged in the realization of IBM's software defined networking (SDN) vision, where we provide novel network virtualization capabilities, codenamed DOVE, to support cloud-scale application delivery by IBM Date Center Networking products as well as by the collaborative Open Daylight project. Our work has been a fundamental component of IBM's "Software Defined Network for Virtual Environments" product as described in an IBM white paper on this product:

"SDN VE began as a breakthrough innovation developed at the IBM Research Laboratories in Haifa, Israel... The technological breakthrough that SDN VE represents demonstrates that IBM is committed not only to accommodating major shifts in technology, but leading them by pioneering new technology models."

OpenStackIn line with IBM's strong backing of open standards and specifications, our cloud computing team is actively involved in contributing to the OpenStack community of open source cloud developers. In doing so, we are directly supporting IBM's involvement in the OpenStack Foundation. Our OpenStack R&D works spans cloud networking, cloud storage and cloud compute services. A significant part of our OpenStack contributions is driven by our leadership position in the Cloud Hosting activity in the FI-WARE European project (see below).

A large part of our team conducts research in the areas of system optimization, specifically targeting the challenges presented by multicore architectures and highly virtualized environments. Our work in this area includes tools and methods for improving software performance using advanced compiler optimizations, post-link optimizations and execution analytics tools (see, e.g., our recent contributions to PowerLinux). As an orthogonal dimension of system optimization, we are developing innovative tools and methods for designing reliable and correct systems, using advanced software test and analysis techniques. All in all, our work on system optimization has resulted in widely recognized contributions to the reliability and quality of software systems developed by IBM, customers and partners. Our work in this area has been recognized by many papers and patents, and was recently highlighted in IBM's Annual Investor Briefing (New York, April 2012). In addition, our technology is routinely used by IBM's highly successful Testing Services business unit, which works with global clients on enterprise software assurance:

"IBM Total Test Quality combines IBM Testing Services with comprehensive automation from IBM Software and leading edge innovation from IBM Research to help clients drive dramatic reductions in cost and schedule while improving overall quality and lowering business risk of their critical business applications." (Quote from IBM offering description)

During the recent years, our team has achieved several landmarks in computer system technologies state-of-the-art. Our team was instrumental in designing an Infiniband-based I/O architecture for IBM's rapidly-accepted XIV Gen 3 Storage product that already has thousands of installations worldwide, delivering unprecedented breakthroughs in storage performance. As pioneers in virtualization technology, we played a key role in the development of IBM's Virtualization Manager Software, announced in late 2006. This technology was recognized as the winner of the ServerWatch Product Excellence Award for 2007, and honored with the prestigious IBM Research Division Accomplishment Award for 2007. Subsequently, in 2008-2010, we have architected and developed the IBM's System Pools technology, now available as a major component of IBM's VMControl product. The compiler and post-link optimizations developed by our team have helped IBM Power systems become an industry leader in TPC-C,SPEC-CPU and SAP benchmarks for Linux, and are used to competitively optimize IBM systems for commercial workloads. Some earlier well-known accomplishments of our department are (1) the invention of the now standard and highly popular iSCSI protocol for storage networks; (2) the Object Storage paradigm, which is now being embraced by the global leading providers of cloud storage; (3) contributions to IBM's Blue Gene supercomputer; and (4) our work on the advanced Copy Services in IBM's flagship storage platform. For these and other achievements, our team has been recognized multiple times by various honors.

Departments

Collaborations and Partnerships

Across all our activities, our team works with internal IBM product organizations as well as with IBM customers. We engage directly in development and delivery projects, partnering with the following IBM business units:

We routinely work with standard organizations to set systems and storage industry standards. A recent example of our work in this area is the CBCS standard for secure access to networked storage. Our team has conceived and developed this standard, and then led the process of its approval by the T10 standards body.

  • Lastly, we collaborate with European academic and industrial organizations on projects of mutual joint interest. These include the following activities:
