Winchester Systems Announces EISA Disk Controller and SCSI Disk Subsystem

Winchester Systems Inc. has announced FlashServer, an EISA disk controller intended for network servers. FlashServer, with Coretest 2.7 performance of 6,000 IOPS (from cache (1 Kb reads), provides RAID reliability for EISA computers.

FlashServer supports 14 SCSI disk driver per controller and up to 200+ Gb disk capacity per server. The controller also supports a variety of tape, optical and CD-ROM devices. The FlashServer caching controller provides two independent SCSI-2 channels supported by up to 128 Mb of on-board cache RAM.

FlashServer's base architecture includes a 32-bit RISC transputer engine with an embedded real-time, multi-tasking operating system; two 32-bit RISC processors that control independent SCSI-2 channels; a 32-bit wide cache RAM; and a single chip, 32-bit EISA Bus Master implementation.

FlashServer is compatible with EISA, SCSI-2, and ASPI, and runs ASPI packages such as Cheyenne, Legato, Sytos Plus, and Corel SCSI. FlashServer supports several modes including: RAID 1 controller-based disk duplexing for fault-tolerant disk arrays; RAID 0 controller-based disk striping for throughput; RAID 10 which combines both striping and duplexing; and disk chaining and partitioning, for translation between physical and logical drives.

FlashServer controllers are available with or without cache. SIMMS (1 or 4Mb) can be used to populate the board to 32 Mb, with plans for Cache capacity to 128 Mb using 16 Mb SIMMs later this year.

Winchester has broadened the target platforms for its SCSI disk subsystem, FlashDisk 2: computers or workstations with SCSI-1 or SCSI-2 ports, including SUN, HP, and IBM hardware running UNIX, Windows NT, or OSF operating systems. FlashDisk 2 provides 800 IOPS per disk, RAID 1+ reliability with hardware disk shadowing, FlashSync spindle synchronization in RAID 1+ mode, and a dual power supply.

FlashDisk 2 supports 780 Mb to 6 Gb per subsystem and can be housed in tabletop, rack mount, or pedestal enclosures. Total storage is limited by the number of SCSI devices supported by the host computer.

The single unit price for FlashServer is $3,000. FlashDisk 2 starts at $10,000 for a 16 Mb cache with 780 Mb storage. For more information, contact Winchester Systems Inc., 400 West Cummings Park, Woburn, MA 01801, (800) 325-3700; FAX: (617) 933-6174.

Sea Change Announces SCSI Navigator Software and ESD Subsystems Kits

Sea Change Corporation has announced SCSI NAVIGATOR, a suite of integrated functions supporting installation and operation of SCSI storage devices on SCO UNIX based systems. SCSI NAVIGATOR utilities are divided into two groups: On-line Utilities and Off-line Utilities. The On-line Utilities run as a privileged application under SCO UNIX and replace several command-line-oriented programs. Functions are provided for disk formatting, device testing, partitioning, performance profiling, and data backup/restore. Full support is provided for partitioning disk drives for both UNIX and DOS operation.

The Off-line Utilities run directly on the system hardware, with no host operating system required. This capability is provided by software which interacts directly with the system's SCSI controller, and lets systems backup tapes be accessed even if the main system disk has failed. Both programs use the same user interface, with color, menus, and context sensitive help.

Sea Change describes a "MISSION CRITICAL backup/restore function," which allows users to perform a partial or full system image backup using the On-line utilities, and in the event of a system disk failure, restore the entire UNIX system using the Off-line utilities "in as little as 10 minutes."

SCSI NAVIGATOR supports SCSI disks or tape drives conforming to SCSI-1 or SCSI-2 standards, and high capacity tape devices including QIC-150, QIC-525, 4mm DAT drives, 8mm helical scan drives, and traditional 9 track drives.

Sea Change also announced the External SCSI Disk (ESD) subsystem kit for UNIX systems. Ranging in capacity from 480 Mb to 2 Gb the ESD kit lets the system support a range of application solutions. The kits include SCSI Navigator, an external SCSI disk with cables, a preformatted disk drive, and (optionally) an Adaptec SCSI controller.

In addition to the ESD kits, several SCSI tape storage kits (525 Mb Streaming, 2.5 Gb Exabyte, 5.0 Gb Exabyte, and 1.3 Gb DAT) and mainframe level SCSI disk kits are also available as "plug and play" products. For more information, contact Sea Change Corporation, 6695 Millcreek Dr., Unit 8., Mississauga, Ontario, Canada L5N 5R8, (416) 542-9484; FAX: (416) 542-9479.

Advanced Archival Products Introduces AMASS 4.0

Advanced Archival Products, Inc. has introduced AMASS 4.0, a UNIX filesystem and driver for jukeboxes. AMASS 4.0 is a direct-access filesystem which supports a single filesystem view of jukeboxes of varied sizes and media types.

The jukebox is available through a single local or NFS mount point. Files and directories can span media, letting the filesystem and directories be of unlimited size, and files can be the full size supported by the host operating system. AMASS 4.0 is compatible with existing applications, UNIX utilities, and network protocols, so application programs which normally access files on magnetic disks can operate with the optical or tape jukebox without modification. AMASS 4.0 maintains an online index of jukebox directories and files, providing magnetic disk equivalent performance without having to load optical or tape media, and magnetic disk caching, which supports multi-user/multi-tasking access and high-speed magnetic disk access of the most recently used file data. AMASS provides multifunction drive support for erasable optical, WORM, and magnetic tape media in the same jukebox. AMASS can also provide a single mount point, a single filesystem interface for daisy-chained jukeboxes on a single platform. AMASS 4.0 supports the most common UNIX platforms, and over 42 jukebox models from 12 manufacturers, with capacities ranging from 3 Gigabytes to many Terabytes.

Prices for AMASS 4.0 start at $6,000. For more information, contact Advanced Archival Products, Inc. 6595 S. Dayton St., Suite 1200, Greenwood Village, CO 80111, (303) 792-9700; FAX: (303) 792-2465.

Puzzle Systems Introduces SoftNet Client

Puzzle Systems Corporation has introduced SoftNet Client, NetWare Client emulation for UNIX platforms. SoftNet Client lets users of HP 9000, Silicon Graphics, and SPARC platforms act as Novell NetWare clients and directly access Intel-based NetWare file servers. The UNIX workstation user can log onto and mount the drivers of NetWare file servers without the need for NFS support on the NetWare server. IPX support is provided to the workstation without interfering with its native TCP/IP capabilities.

SoftNet Client does not require UNIX kernel reconfiguration or disk partitioning. In addition to NetWare server file access, the workstation user can send print jobs to NetWare printers. At present, NetWare 2.2 and 3.11 server types are supported by SoftNet Client. According to Puzzle Systems, "SoftNet Client further adds to the interoperability option available to users of mixed NetWare/UNIX environments. If you would like to have your UNIX platforms also act as fast NetWare compatible file servers, consider SoftNet Utilities; if you prefer to have your UNIX platforms act as NetWare compatible clients, SoftNet Client is the correct product."

SoftNet Client is priced at $395 for a single user license and $1,495 for a five-user license regardless of UNIX platform type. For more information, contact Puzzle Systems Corporation, 16360 Monterey Rd., Suite 250, Morgan Hill, CA, 95037, (408) 779-9909; FAX: (408) 779-5058.

Interstream Releases eNFS/PFS

Interstream, Inc., has released eNFS/PFS (Personal File Server), an eNFS implementation that resides on client workstations and provides continued access to NFS data during interruptions due to NFS server failures or overloading. Built on Interstream's eNFS/Cache, eNFS/PFS loads transparently into the client workstation and is positioned between the application environment and the workstation's TCP/IP communications software, where it monitors NFS requests during normal operations. eNFS/PFS monitors the combination of server-client NFS requests and Remote Procedure Call (RPC) responses and activates whenever either of these operations requires intervention due to a non-responding NFS server.

Systems administrators can give developers isolation from temporary interruptions in a server's availability through eNFS/PFS's disconnected NFS write subsystem. This feature allows the client's own disk to act as a personal NFS server when the mounted NFS server is not responding. eNFS/PFS also supports reconnection services that update the appropriate NFS server when communications are restored. eNFS/PFS lets portable UNIX NFS clients operate disconnected from an NFS server. No modifications are necessary to NFS server or NFS clients not using eNFS/PFS.

eNFS/PFS, including eNFS/Cache, is priced at $495 per NFS client. Upgrades from eNFS/Cache are $300 per client. For more information, contact Interstream, Inc., 1501 Reedsdale St., Pittsburgh, PA 15233-2329; (412) 323-8000; FAX: (412) 323-1930.

The PT-VME430/432 are two fast/wide VMEbus SCSI-2 host adapters designed for use in both VME and VME 64 systems, providing up to 17-19 Mb/sec sustained data transfer rates. The PT-VME430/432 incorporates a SCRIPTS processor and two custom ASICs, and Performance Technologies claims a reduction in overhead to about 2 usec per data block. The PT-VME-430/432 supports 8- and 16-bit SCSI bus widths, with either differential or single-ended operation. Users can mix and match up to thirty-six combinations of 50-pin ribbon, 50-pin shielded or 68-pin shielded connectors on one or both channels. The PT-VME430/431 host adapters support sixteen devices on the primary SCSI-2 channel plus sixteen on the optional secondary SCSI-2 channel.

The PT-VME600 is an FDDI node adapter for VME64, which uses the National Semiconductor two-chip FDDI chip set. Performance Technologies describes the PT-VME600 as easily maintaining a sustained data throughput of over 90% of the LAN media bandwidth. The dual-attached (DAS) version of the PT-VME600 is designed for front-end network applications such as image processing, multimedia, and CAD/CAM; but it is also well suited as a backbone network to tie together the main components of a distributed system. The FDDI interface conforms to ANSI (X3T9.5) standards and has been optimized for network control and protocol processing. PMD options include ST and MIC Multimode fiber and SDDI copper. The controller can be configured as either a single or dual attach. Extension via a P2 connector provides concentrator support with a dual path interface to an 8-port copper media master port card or a 4-port copper or optical master port card. The PT-VME340 is a VMEbus Serial I/O module for T1/E1 rates - a four-port wide area network controller designed to sustain serial I/O rates up to 10 Mb/sec. The PT-VME340 is build around the Zilog 16C32 ISCC, based on the Z8530 SCC, but including an eight-channel 16-bit I/O DMA controller with "chained Link List capabilities" for high-speed data movement. The SIO throughput of the PT-VME340 is in excess of 4 Mb/sec on all four ports (full duplex) and up to 10Mb/sec on one port (full duplex). Physical interfaces are supplied via the PTI Line Adapter Boards (LABs), providing RS-232C, RS-422, RS-485, Mil Std 188C/114, and V.35 interfaces. The PT-VME340 controller is based on a Motorola 68EC030, with 1 to 4Mb or onboard DRAM and a high-performance VME64 VMEbus interface.
