Mass Storage Systems CRAY Data Migration Facility and Tape Management Facility Update Neil Bannister and Laraine MacKenzie This paper will review status and plans for both Cray and SGI platforms. Since the last CUG meeting DMF four was released. This has presented the DMF team with new challenges which will be covered in this paper. The paper will also report progress and release plans for the TMF and CRL products. Storage Directions Art Beckman Data is growing faster than ever, with recent growth exceeding Moore's Law. The combination of Big Data and the Net is already creating and will create much more stress on the infrastructure (i.e., InfraStress) of computing. This talk examines storage technology trends expected over the next few years, and tries to pinpoint the likely stress issues and reasons and looks at some of the potential solutions for the problems. Storage Management-—Seven Years and Seven Lessons with DMF Robert Bell CSIRO has been using Cray's Data Migration Facility (DMF) for storage management for over seven years. This talk will focus on seven lessons learned in the seven years. These are: Good storage systems are vital to productivity of users and administrators. Good storage systems cope with generational change transparently to the users. Good storage systems provide long-term safe keeping for users' data. Good storage systems need good hardware, software and support staff. Good storage systems have to be more than an archive. Good storage systems have to cope with many files as well as large files. Good storage systems provide good access paths. KART: a simple client/server interface to access different tape devices at CINECA Site Sergio Bernardi KART was developed to provide a controlled and easy access to different tape devices at CINECA site. Based on a client/server architecture, KART provides a set of commands in order to define logical volumes, read from volumes, write to volumes. The set of commands is also accessible via Web page (under development). STK ACS Tape Drives in an SGI/Cray Environment Ulrich Detert In spring '99 new STK tape drives 9840 (formerly called Eagle) will become available for SGI/Cray systems. The capacity of the new tapes is 20 GB with a peak transfer rate of 10 MB/s. The paper describes performance characteristics for the new tapes in comparison to the older tape drives 9490 (Timberline) and 4490(Silverton) with BMX and SCSI interfaces. Related topics of installation and handling of the tapes are also discussed. CXFS: A Clustered File System from SGI R. Kent Koeninger CXFS is a clustered file system that provides near-local IO performance for shared access to Fibre Channel disks from multiple hosts. This talk will give an overview of CXFS and the status of the CXFS product development. FibreChannel and Storage Area Networks on the Origin 2000 Thomas Ruwart FibreChannel is fast becoming the standard for connecting storage to high performance machines. This talk describes the performance of FibreChannel storage on the SGI Origin2000 and its use in creating Storage Area Networks (SANs).
