Stitch or anyone: Let me ask you for your latest feedback on whether you see any challenger to the HTCH TSA suspension and whether any drive companies are managing to produce Pico MR drives without TSA. I'm not aware of any analysts that don't regard TSA as the wave of the future.

A very good showman indeed. Thanks, GM, for the reminder (I think). I wonder how much of his own money he has invested in this venture. I doubt he sold his cars. But he still has something to prove, I expect. Ala Mitchell and Tandon. No offense to him, exactly, but I wouldn't really mind it if he ends the same way. In the FWIW category-- I'm leaving town for a week. And while this ranks right up there with the Super Bowl indicator, over the years this seems to lead to some sharp volatility, both up and down. Good luck everyone, and have a good week. Best wishes, Sam

An article on Ultra3 SCSI vs. FC: September 21, 1998, Issue: 733 Section: News & Analysis SCSI Moves Up To Even Faster Speed Chuck Moozakis The future of SCSI came into focus last week as a group of vendors endorsed a new interface capable of pumping data to peripheral devices at speeds up to 160 MBps. The new Ultra160/m SCSI interface is based on the next-generation Ultra3 SCSI technology, and will include support for management and performance features such as double transition clocking, cyclical redundancy checking (CRC) and domain validation. Systems based on the new specification, which was ratified in July by the SCSI Trade Association, will begin to appear in 1999. The systems and storage suppliers endorsing the spec include Adaptec Inc., Fujitsu Computer Products of America Inc., Hewlett-Packard, LSI Logic Corp. and Quantum Corp. Ultra3's double transition clocking transfers twice the amount of data in the same clock period as Ultra2 SCSI, doubling the throughput of Ultra2 and completely overshadowing conventional SCSI, which moves data at 5 MBps to 20 MBps. The advent of Ultra160/m should be a boon to IT managers who want high-speed interfaces to link SCSI devices directly to LANs. And the interface will be additionally attractive because it will be compatible with the older SCSI interfaces that now dominate the industry. Beyond the changes in speed, Ultra160/m also has improved management features, among them domain validation, which enables the interface to dynamically adjust data transfer rates to accommodate lower-speed devices. CRC bolsters the reliability of SCSI data transmission through enhanced detection of communication errors. But the jury remains out regarding how Ultra160/m might be used in sophisticated high-speed storage area networks (SANs) that connect hundreds of devices. Independent consultant Brenda Christensen said Fibre Channel, which moves data at speeds up to 100 MBps, will likely continue to be the dominant interface for SANs. Fibre Channel's ease of management; support for SCSI, IP, ATM and other topologies; and ability to transmit data over distances up to 6.2 miles are all contributing factors, she added. "At the end of the day you would have to have some pretty sophisticated people to manage" SANs with SCSI, she said. Copyright r 1998 CMP Media Inc. So is she implying that a company could have pretty unsophisticated people to manage a Fibre Channel network?
