whitepaper Peta-Scale I/O With the Lustre File System2008-02-01 Sun Microsystems
  This paper describes low-level infrastructure in the Lustre file system that addresses scalability in very large clusters. The features described deal with I/O and networking, lock management, recovery after failure, and other scalability-related issues. The Lustre file system first went into production in Spring 2003 on the Multiprogrammatic Capability Resource (MCR) cluster at Lawrence Livermore National Laboratory (LLNL). The MCR cluster was one of the largest clusters at that time with 1100 Linux compute nodes as Lustre clients. Since then, the Lustre file system has been deployed on larger systems, notably the Sandia Red Storm deployment, with approximately 25,000 liblustre clients, and the Oak Ridge National Laboratory (ORNL) Jaguar system, which is of similar scale and runs Lustre technology both with Client-Node Linux (CNL) and with Catamount.

whitepaper Microsoft Dynamics CRM 4.0: Performance and Scalability - User Scalability for the Enterprise2008-02-01 Microsoft
  Microsoft Dynamics CRM 4.0 is designed to help enterprise organizations attain a 360-degree view of customers, achieve reliable user adoption, adapt quickly to business change, and accelerate project delivery and returns-all on a platform that provides enterprise levels of scalability and performance. This white paper focuses on user scalability.

Microsoft, together with Unisys Corporation, completed benchmark testing of Microsoft Dynamics CRM 4.0 running on the Windows Server 2008 operating system with Microsoft SQL Server 2008 database software. Benchmark results demonstrate that Microsoft Dynamics CRM can scale to meet the needs of an enterprise-level, mission-critical workload of 24,000 concurrent users while maintaining performance at sub-second response times.

whitepaper Virtuozzo Containers for Windows Capacity and Scaling2008-02-11 Parallels
  One of the keys to a successful virtualization project is the effective management of virtualized servers. Without proper optimization, your virtual infrastructure may experience performance and even stability issues.

This white paper provides IT managers with the tools to plan and implement a Parallels Virtuozzo virtualization project, including how to evaluate and optimize the performance of virtualized severs. Read detailed information about consolidation ratios, resource usage and evaluation, and system density to ensure you achieve the full benefits of a virtualized infrastructure.

whitepaper A Scalability Service for Dynamic Web Applications2008-01-01 Carnegie Mellon University
  Providers of dynamic Web applications are currently unable to accommodate heavy usage without significant investment in infrastructure and in-house management capability. This goal is to develop technology to enable a third party to offer scalability as a subscription service with "Per-click" pricing to application providers. This paper has developed a prototype proxy caching system able to scale delivery of dynamic Web content to a large number of users. This paper reports initial positive results obtained from this prototype that point to the feasibility of this goal. It also reports the shortcomings of the current prototype, the chief one being the lack of a scalable method of managing data consistency.   
whitepaper Scalability and Accuracy in a Large-Scale Network Emulator2008-01-01 Duke University
  This paper presents ModelNet, a scalable Internet emulation environment that enables researchers to deploy unmodified software prototypes in a configurable Internet-like environment and subject them to faults and varying network conditions. Edge nodes running user-specified OS and application software are configured to route their packets through a set of ModelNet core nodes, which cooperate to subject the traffic to the bandwidth, congestion constraints, latency, and loss profile of a target network topology. This paper describes and evaluates the ModelNet architecture and its implementation, including novel techniques to balance emulation accuracy against scalability.   
whitepaper Modularizing Variability and Scalability Concerns in Distributed Real-Time and Embedded Systems With Modeling Tools and Component Middleware2008-01-01 Vanderbilt University
  Developing real-time software for large-scale Distributed Real-time and Embedded (DRE) systems is hard due to variabilities that arise from integration with various subsystems based on different programming languages and hardware, OS, middleware platforms, fine tuning the system to satisfy a range of customer requirements, such as various Quality-of-Service (QoS) properties, and changing functional and QoS properties of the system based on available system resources. This paper describes the experience of applying Model-Driven Development (MDD) tools and QoS-enabled component middleware technologies to address domain- and middleware-specific variability challenges in an inventory tracking system, which manages the storage and flow of items in warehouses.

whitepaper Streams, Security and Scalability2008-01-01 AT&T Labs-Research
  Network-based attacks, such as DDoS attacks and worms, are threatening the continued utility of the Internet. As the variety and the sophistication of attacks grow, early detection of potential attacks will become crucial in mitigating their impact. This paper argues that the Gigascope data stream management system has both the functionality and the performance to serve as the foundation for the next generation of network intrusion detection systems.

whitepaper DOH: A Content Delivery Peer-to-Peer Network2008-01-01 Swedish Institute of Computer Science
  Many SMEs and non-profit organizations suffer when their Web servers become unavailable due to flash crowd effects when their web site becomes popular. One of the solutions to the flash-crowd problem is to place the web site on a scalable CDN (Content Delivery Network) that replicates the content and distributes the load in order to improve its response time. This paper presents the approach to building a scalable Web Hosting environment as a CDN on top of a structured peer-to-peer system of collaborative web-servers integrated to share the load and to improve the overall system performance, scalability, availability and robustness. Unlike cluster-based solutions, it can run on heterogeneous hardware, over geographically dispersed areas.

whitepaper Pastis: A Highly-Scalable Multi-User Peer-to-Peer File System2008-01-01 French National Institute for Research in Computer Science and Control
  This paper introduces Pastis, a completely decentralized multi-user read-write peer-to-peer file system. In Pastis every file is described by a modifiable inode-like structure which contains the addresses of the immutable blocks in which the le contents are stored. All data are stored using the Past Distributed Hash Table (DHT), which the paper has modified in order to reduce the number of network messages it generates, thus optimizing replica retrieval. Pastis' design is simple compared to other existing systems, as it does not require complex algorithms like Byzantine-Fault Tolerant (BFT) replication or a central administrative authority. It is also highly scalable in terms of the number of network nodes and users sharing a given file or portion of the file system.

whitepaper An Incrementally Scalable Multiprocessor Interconnection Network With Flexible Topology and Low-Cost Distributed Switching2008-01-01 Monash University
  Massively parallel computing architectures are becoming widely accepted in many computationally intensive areas. One of the prime advantages touted is their scalability, and yet while in principle a good degree of scalability is possible, in practice the unit of scaling is very coarse. The net effect of this is to make incremental expansion of such machines impractical except for large and expensive expansion to multiples of the original size and in some cases expansion by powers of two is required. In this paper a multiprocessor interconnection scheme with low fixed overheads and linear incremental scaling costs is described.
