COMPETITIVE NEWSFLASH
SEQUENT ANNOUNCEMENT ANALYSIS
February 5, 1991
WHAT'S NEW?
-----------
On January 23, 1991, Sequent Computer Systems introduced the Symmetry
2000 family of computers based on the Intel 80486 microprocessor.
Sequent also introduced communications, internationalization, and
client/server enhancements to its DYNIX/ptx operating system.
The following is a 4-page summary and analysis of Sequent's
announcement. This Competitive Newsflash is available from the
Competitive Hotline; the subject is "SEQNEW."
ANNOUNCEMENT SUMMARY
--------------------
Below are the highlights of Sequent's press release.
* The Symmetry 2000 is a four-member family of systems based on
Sequent's symmetrical multiprocessing (SMP) architecture and the Intel
80486 CPU. The Symmetry 2000 family is available now.
* The Symmetry 2000 includes the S2000/700 system specifically
designed for large MIS installations. It can incorporate up to 30
Intel 80486 processors, and ranges in price from $190,000 to
$2,500,000.
* The S2000/200 system and S2000/400 system models support up to 6 and
10 Intel 80486 processors respectively. These systems deliver midrange
performance that is targeted for departmental computing, decision
support, and file and print server capabilities.
* The S2000/40 is an entry level system which uses one Intel 80486 CPU
to implement small workgroup applications involving from 25 to 30
users. NOTE: The S2000/40 is a single CPU system which is a box swap
upgrade to the S2000/200.
* In a recent ORACLE TP1 benchmark, audited by Codd and Date, Symmetry
2000 achieved a performance rate of 354 transactions per second on a
16-CPU system. NOTE: Sequent still has not published TPC-A benchmark
performance.
* The Symmetry 2000 family runs DYNIX/ptx, Sequent's version of UNIX.
DYNIX/ptx is fully compliant with POSIX, FIPS 151-1, SVID, and X/OPEN's
XPG3, and has been selected by AT&T's USL as the primary development
platform for System V Release 4 ES/MP.
* DYNIX/ptx international language support is made possible by
incorporating AT&T's Multi-National Language Standard (MNLS). Sequent
announced the availability of the first two international versions of
DYNIX/ptx (Japanese and Korean). Sequent plans to deliver French and
German versions of DYNIX/ptx in mid-1991.
* Sequent's new communications and connectivity products include:
- ptx/X.25 (a wide area communications product allowing multiple high
speed X.25 connections)
- ptx/BSC (which allows connection to bisynchronous networks
supporting 3270, 2780/3780 and HASP-based nodes)
- parallel STREAMS support
- kiNET software from Ki Research (which allows Symmetry 2000 systems
to communicate directly with DECnet hosts and LAT terminal server users
on Ethernet-based LANs)
- LMserver (which allows Ethernet-based users of Microsoft's LAN
Manager clients to connect to and use Symmetry systems as file, print
and application servers
- ptx/WINDOWS (which allows users to create graphical windowed
applications and is based on the latest X Window System release)
- OSF/Motif User Environment (which allows developers to create X-
based applications which are compatible with Presentation Manager
appearance and behavior)
* Sequent's client/server support is addressed by its ptx/T
Transaction Performance Monitor. The ptx/T is an enhanced version of
AT&T's TUXEDO/T product for a SMP environment. The ptx/T software
manages all communications within client/server systems allowing one or
more servers to process requests from multiple clients.
* The old Symmetry machines will be upgradable to Symmetry 2000
performance. Upgrade kits will cost $20K to $25K for subsystems and
diagnostics, plus the price of the 80486 dual-processor boards. In
addition, a new version of DYNIX/ptx due out early in the second
quarter will allow Sequent owners to run a mix of 80386 and 80486
processor boards in their machines.

HP SELLING POINTS TO REMEMBER
-----------------------------
* Sequent's limited system bus bandwidth may limit overall system
performance.
- The supposedly new S2000 family still uses the old system bus (80
MB/s peak, 53.3 MB/s sustained) which has limited bandwidth.
- Previous performance information showed that Sequent's 80386
systems performance peaked around 16 to 22 CPUs. With the 80486,
system performance is suspected to peak around 12 to 16 CPUs.
- Sequent published peak performance with twenty-two 80386 CPUs
using the TP1 benchmark, and is now publishing peak performance with
sixteen 80486 CPUs using the same benchmark. This supports our point.
Note also that the TP1 benchmark is NOT a good indicator of overall
system performance. The TPC-A benchmark is a much better indicator of
overall system performance; so far Sequent has not published TPC-A
numbers. Sell your customer on the advantages of TPC-A over TP1. See
the Competitive Hotline for more details (Subject: 800SPERF and
PERFBRF1).
- Sequent is using 1970's I/O technology. Sequent uses low
performance MULTIBUS 1 for their I/O bus, and low performance SMD for
their disk interface technology.
- Therefore, Sequent's claim of linear performance up to 30
processors is not possible in a real customer environment. For
applications with a large number of users, performance drops off
dramatically as more CPUs are added. See the Competitive Hotline for
more details (Subject: SEQSMP).
* HP-UX has an unequaled position as a leader in both standards
compliance and commercial functionality!
- HP-UX is fully compliant POSIX 1003.1, SVID, XPG3, and to
incorporate OSF programming interfaces as they become available.
- With over 300 employees participating on 179 standards committees
and subcommittees, HP is the leader in driving and adopting standards
for our customers benefit.
- HP offers an unparalleled rich commercial environment including,
system management, information management, and commercial CASE
products. HP's HP-UX systems management services include: system
availability, performance, security, operations control, storage,
accounting, and configuration.
* HP-UX provides transparent support for a user's national language,
as well as tools for software developers to internationalize
applications.
- HP has defined codesets to support 22 languages!
- HP's National Language Support is compliant with the
International Extension of XPG2 base.
- X/OPEN has adopted HP's National Language Support as a basis for
their standard.
* HP can provide superior networking functionality.
- Sequent is currently moving its limited networking functionality
from DYNIX to DYNIX/ptx, its POSIX compliant operating system.
- HP supports the OSI (Open System Interconnect) model which
provides a framework for system and network management.
* HP also offers AT&T's Tuxedo Transaction Processing (TP) monitor.
- HP has announced that we will be delivering a strategic TP
monitor based on Transarc's technology. So far the following companies
have endorsed Transarc's technology: IBM, Stratus, Sybase, Informix,
JYACC, and Independence Technology Inc.
Conclusion:
* Sequent's new Symmetry 2000 systems are a renaming of their old
systems, except for the replacement of the 80386 CPU with the 80486.
This may result in slightly better batch performance, but still
significantly lower batch performance than HP's Series 800!
* The software enhancements that were announced were already available
on their old DYNIX operating system. Sequent is just announcing the
availability of these features on their POSIX compliant DYNIX/ptx. HP-
UX has been POSIX and XPG3 compliant and offers superior commercial
functionality.
