Fujitsu Succeeds in Constructing High-Performance Linux Cluster System

-- Is World's First with InfiniBand Technology and DAFS --

Tokyo, February 25, 2002 -- Fujitsu Limited, Fujitsu Prime Software Technologies Limited (Fujitsu PST) and Fujitsu Laboratories Ltd. today announced their success in realizing the world's first high-performance Linux cluster (*1) system using Direct Access File System (DAFS) (*2) high-speed file sharing protocol and InfiniBand (TM) (*3) inter-memory data transfer.

The new system achieves six times the data transfer efficiency during file read with only 1/17th the CPU utilization rate in comparison with standard NFS (Network File System) solutions. This breakthrough will enable the creation of systems optimized for use in the fields of biotechnology, fluid analysis and structural analysis.

Fujitsu's PRIMERGY Intel-based server platform was used for the new cluster system, together with Fujitsu PST's DAFS-based high-speed common file system, PSTorage InfiniFS (*4). The system consists of a single file server running DAFS, 16 (32CPU) DAFS clients loaded with high-performance SCore (*5) cluster software linked using InfiniBand technology.

Fujitsu PST is moving toward commercial release of PSTorage InfiniFS, and a trial installation of the new cluster system at Japan's High Energy Accelerator Research Organization is planned for April 2002.

The system is being demonstrated at the Intel Developers Forum, Spring 2002 (Feb 25 - 28), which is being held at the Moscone Center in San Francisco, California.

[System configuration]

  1. DAFS
    Hardware:PRIMERGY MS610 x1 (CPU:Intel (R) Pentium (R) lll Xeon 700MHzx2, memory: 2GB)
    InfiniBand specification Host Channel Adapter
    Software:RedHat 7.2 (kernel 2.4.9)
    File system:PSTorage InfiniFS

  2. PC Cluster
    Hardware:PRIMERGY L200 x16 total 32CPU (CPU:Intel Pentium lll-S 1.26GHzx2, memory: 2GB)
    InfiniBand specification Host Channel Adapter
    InfiniBand specification Switch
    Cluster S/W:SCore
    Application:NCBI-BLAST (R) (*6)

(*1) Linux Cluster
Linux-based parallel-distributed processing system than can connect IA servers in clusters ranging from several units to several thousand units.
(*2) DAFS (Direct Access File System)
DAFS is an open protocol for accessing and controlling files in a local area network (LAN) environments such as data centers. It maximizes the performance of high speed network transfer devices, such as InfiniBand, cLAN and Myrinet, that use Operating System- independent "memory-to-memory" transfer network technology. In comparison with the file sharing protocol of NFS and similar systems, CPU utilization rates are significantly reduced and much higher data transfer speeds are achieved. The DAFS Collaborative is making progress towards formal standardization under the IETF. As a member of the DAFS Collaborative, Fujitsu PST is actively participating in efforts to promote standardization. Recently the "DAFS Implementers Forum" of the Storage Network Industry Association (SNIA) has succeeded the DAFS Collaborative.
(*3) InfiniBand Technology and InfiniBand (SM) Trade Association
The InfiniBand (SM) Trade Association advocates InfiniBand technology as the next-generation I/O specification for connecting multiple computers, making 2.5Gb/s high-speed connections possible. The InfiniBand (SM) Trade Association was established by Compaq, Dell, Hewlett-Packard, IBM, Intel, Microsoft and Sun Microsystems. Fujitsu participates as a Member Company and Fujitsu Siemens computers as a Sponsoring Member Company.
(*4) PSTorage InfiniFS (tentative name)
A DAFS protocol based, high-speed file sharing system developed by Fujitsu PST. Runs on IA-32 architecture (RedHat Linux 7.2) Linux platforms comprising both server and client software. Sales will start in the second quarter of Fiscal 2002.
(*5) SCore
Cluster system software initially developed as part of the Real World Computing Partnership (RWCP). SCore is now being marketed by the PC Cluster Consortium.
(*6) NCBI-BLAST (Basic Local Alignment Search Tool)
Developed by the National Center for Biotechnology Information (NCBI). The BLAST algorithm enables searches for DNA protein matches in a homology search program-based database.
