ARTISOFT ANNOUNCES CORSTREAM DEDICATED SERVER

Offers High Performance, Fault Tolerance & Mission-Critical Reliability for
LANtastic Network Users

(TUCSON, AZ--May 16, 1994)--Artisoft, Inc. announced today the CorStream
server, a dedicated server for its LANtastic network operating system. The
server is a high-performance, 32-bit LANtastic network NetWare Loadable
Module (NLM) combined with a runtime version of the Novell NetWare 4
32-bit operating system. The CorStream server is expected to begin
shipping during June 1994.

"The CorStream server combines in one offering the recognized industry
leaders of client and server technologies, resulting in an ideal
networking solution for users who wish to have familiar peer-to-peer
functionality along with the performance and expandability of a dedicated
server," said Artisoft Vice President of Engineering Sunil Padiyar. "The
CorStream server brings users the power of the Novell NetWare platform
while maintaining the LANtastic network's ease of use. Incorporating
power, performance, fault tolerance and mission-critical features, we
tailored this product as an easy-to-use network server ," he added.

Significant Features

The CorStream dedicated server provides substantially increased performance
to LANtastic v5.0 and v6.0 networks without adding complexity or changing
the way workstation users work. Seamlessly integrated into the LANtastic
environment, the CorStream server appears as another LANtastic server to
LANtastic v5.0 and v6.0 network clients. It provides the familiar look and
feel of the LANtastic network system while providing additional features
and increased performance capabilities, including fault tolerance, file
system/media management, mission-critical reliability and applications
compatibility.

Performance

The CorStream server is able to provide high performance because it is
built on a 32-bit multi-tasking, multi-threaded operating system. It
incorporates features such as concurrent drive seeks and data spanning to
take advantage of the 32-bit platform. The CorStream server will have the
ability to simultaneously seek data across multiple disk drives.

Another benefit of the 32-bit operating system is that users are not
limited to file caching of 16 MB. The CorStream dedicated server allows
users to install as much memory as they wish for optimal throughput. A
result of these combined features will be faster access to network data
and increased user productivity. 

Fault Tolerance

The CorStream server also supports System Fault Tolerance (SFT) Level 1
("Hot Fix") and SFT Level 2 for LANtastic network users. In SFT Level 1,
the system automatically recognizes bad sectors on the drive and forwards
the data to undamaged areas.

The Artisoft CorStream server also complies with SFI Level 2 functionality
by providing disk mirroring and disk duplexing capabilities. Disk
mirroring delivers fault tolerance through one hard drive controller card
and two hard drives, with one drive mirroring the other. Disk duplexing
adds to the fault tolerance capability by providing a second hard drive
controller. Should one drive or controller fail, the second will assume
all server functions without downtime.

File System / Media Management

The CorStream dedicated server also features background file compression
that is configurable by the system administrator as a background task on
the server. This enables the server to almost double its disk capacity in
terms of data storage. When this feature is activated, files that are not
in use are automatically compressed by the dedicated server. The files are
decompressed on demand when they are accessed and read by the user. In
addition, the CorStream server supports many types of storage devices,
including CD ROM drives, WORMs (write once read many), and jukeboxes.

Mission-Critical Reliability

Artisoft's CorStream server will also provide the mission-critical
reliability that users expect in a server environment. In addition to the
Hot Fix and disk duplicating features, supported drivers can perform read
after write verification to provide a high level of confidence in data
integrity.

Further reliability comes with the system's redundant file structures,
which makes two copies of file allocation tables and directory entries and
puts them on different disk sections. This feature also places copies of
each file's directory entry on separate areas of the disk.

"The CorStream server was developed based upon customer demand. Many of our
current customers are already dedicating a PC for server use. Now they
have an easy upgrade path to a more powerful, centrally managed server
platform," said Artisoft's Vice President of Sales and Support Joel A.
Davis.

"We believe the CorStream server is an excellent choice for branch offices,
departmental networks and those in small-to-medium network installations,
who want the benefits that come from dedicating a PC to act as a server.
Users will have power for transaction-intensive functions such as
databases, compatibility with existing hardware and software, and
scalability options to add clients, servers and applications as needs
change and their networks grow," he said.

Pricing and Availability

The CorStream dedicated server will be offered as a standalone server for
use within existing LANtastic networks, or as a network solution kit
including the server and the LANtastic v6.0 client software. Both
offerings will be sold in 5-, 10-, 25-, 50- and 100-user kits. Pricing for
these user kits will start at $949 (MSRP) for the 5-user standalone
version, and $1149 (MSRP) for the 5-use network bundle. For a limited
time, all kits sold in the U.S. will include an Eagle Technology EP3210
EISA Ethernet adapter, and all kits sold internationally will include an
Eagle Technology NE3210 EISA adapter. The server will be available through
Artisoft sales channels.

When the CorStream server begins shipping, Artisoft will make available a
separate technical support line with representatives specially trained for
dedicated server queries.
