Interphase Announces Fibre Channel Adapter for PCI Bus

Provides Next Generation Mass Storage Connectivity for Servers and
Workstations

LAS VEGAS, NV, APRIL 2, 1996 -- Interphase Corporation (NASDAQ/NMS: INPH),
a leader in performance I/O for high speed networks and mass storage,
today announced the 5526 PCI Fibre Channel Adapter.

Designed to deliver gigabit performance to servers and power workstations,
the 5526 is a full-featured Fibre Channel adapter which provides single
port connectivity from a PCI slot. The 5526 supports 1062, 531 and 266
Mbaud link speeds; supports Fibre Channel Class 1, 2, and 3 services;
supports Fibre Channel Arbitrated Loop (FC-AL), Point-to-Point, and Fabric
(Cross-switched) topologies; and supports up to 16,384 concurrent SCSI I/O
operations.

"It's exciting to see a key player in the high-end mass storage market
offer products for Fibre Channel," said Ken Osterberg, product marketing
manager at Seagate Technology. "As one of the first vendors in the
industry to offer functional Fibre Channel Arbitrated Loop connectivity,
Interphase will definitely help accelerate the deployment of Fibre Channel
technology."

(I)CHIP AND HP TACHYON TECHNOLOGY

The 5526 utilizes the Hewlett-Packard Tachyon Fibre Channel protocol engine
and the Interphase (i)chipTPI ASIC which provides a single chip PCI bus
interface for the Tachyon. With the (i)chipTPI, the 5526 provides superior
throughput by bursting data of up to 2K across the bus with intelligent
prefetching for read operations, thereby minimizing the performance impact
of PCI bus latencies.

PRODUCT AVAILABILITY

The Interphase 5526 PCI Fibre Channel adapter is list priced at $1, 995 and
will begin shipping in limited quantities in July '96. The 5526 comes
complete with drivers for Microsoft Windows NT & Novell NetWare 4.x.

ON DISPLAY AT NETWORLD + INTEROP LAS VEGAS '96

The 5526 is on display in the Interphase booth (#3527) at the Networld +
Interop tradeshow in Las Vegas, April 2 to April 5. The Interphase exhibit
demonstrates mixed SCSI and IP traffic between two PCI-based host systems
via a Fibre Channel disk cluster and Arbitrated Loop Hub. This shows how
to use concurrent host-to-host communications and disk block device
transfers to form clusters of machines built around a common storage
subsystem. In the real world, these storage cluster configurations can be
used to increase reliability, availability and performance for a variety
of applications ranging from digital video and electronic pre-press
systems to network and web server clusters.

Interphase Corporation is a leading supplier of desktop and server I/O
products for high speed networks and mass storage topologies. The company
is a principal member of both the Fibre Channel Association (FCA) and the
Fibre Channel Loop Community (FC-LC), and is active on the ANSI X3T11
Technical Committee which is responsible for Fibre Channel standards.
Interphase is a leading proponent of fostering interoperability in the
industry and sponsors multi-vendor interoperability test sessions for
numerous technologies, including ATM and Fibre Channel, at its corporate
facilities in Dallas, Texas. Additional information about Interphase and
