9. Questions and Answers
=========================
Are there any plans to support Portable NetWare servers other
than HP 9000 Series 800 or HP 3000 Series 900?
No testing has been done on other Portable NetWare servers,
including the HP 9000 Series 700, HP 1500 (TI), and non-HP
servers; however, we are not aware of a reason the Windows
Client would not work with these servers.
Why is such a large memory configuration supported on the Windows
Client?
Good performance with a Windows Client demands that swapping be
kept to an absolute minimum. We anticipate with a 32-bit
operating system, such as OS/2 or the next generation
DOS/Windows that much larger memory configurations will be
needed. Also, a large memory allows many forms (and other data
files) to be stored in a RAM disk.
What 3270 and X-Terminal solutions are available for the Windows
Client?
It is our intention to support the popular third-party 3270 and
X-Terminal emulators on the Windows Client. Because the
Windows Client supports no I/O expansion slots, it will not be
possible to support 3270 products which require an I/O card.
WRQ offers both 3270 and X-Terminal emulators. The WRQ
emulation products can use RNS networking services, thereby
eliminating the cost of extra networking software. The WRQ
3270 emulation product runs on Telnet, so the customer's
environment needs to be qualified to accept a Telnet-based 3270
connection.
Is a return credit offered when upgrading terminals (or PCs) to
the Windows Client?
Because of the aggressive pricing for the Windows Client, it is
not possible to offer a structured return credit program for
customers upgrading to the Windows Client.
Won't the Windows Client saturate my customer's LAN?
In the vast majority of situations, the LAN is not a
performance bottleneck. With Portable NetWare, the server and
it's LAN interface is normally the bottleneck. Native NetWare
servers tend to be disk I/O bound and also limited by the
throughput of the LAN interface. In situations with multiple
servers and hundreds of clients, it may be advisable for the
customer to break their LAN into multiple segments where each
segment contains a subset of the total Clients and their file
server.
How long does it take to start up a Windows Client?
On a lightly loaded server with only one user starting up a
Windows Client at a time, it takes 30-40 seconds to run the
start-up hardware diagnostics, boot and download DOS, and load
Windows and Reflections. With several users simultaneously
starting up Windows Client, the time stretches out to 60-90
seconds due to the cummulative load on the server.
Normally, user log-on will be spread out over a reasonable
period of time at the beginning of the work day (e.g., from
8:00-9:00 AM). As a result, it is unlikely that there will be
more than a few users starting up Windows Clients at the same
time. However, in unusual situations (e.g., after a power
failure) where a large fraction of the users are starting up
the Windows Client, it can be expected that startup times can
stretch to 10 minutes or more.
For HP 9000 servers using Portable NetWare, good performance
downloading applications requires use of the latest NetWare
release (version A.11.02), as previous versions were much
slower.
Are there any other special performance considerations when
operating the Windows Client?
Yes, when configuring HP 3000 systems you need to take into
account the added load of terminal connection using NS/VT.
Virtual terminal with a LAN-connected PC is less efficient than
serial connection using AFCDP on the DTC (20% more CPU
overhead). For this added performance overhead, HP 3000
customers receive the benefits of a graphical user interface
offering multiple sessions, multiple hosts, windowing, and
color displays.
Because the HP 9000 uses Telnet both for LAN-connection and
DTC-connection, performance will be identical for terminal
emulation in a serial mode and in a LAN environment (As is the
situation today, direct MUX connection will be faster than
either DTC or LAN-connection).
How much disk space is required on the file server for the
Windows Client?
The Windows Client is much more efficient in using disk space
than traditional PCs with integrated disks. Because only one
copy of the application is needed (for network-aware, shared PC
applications), you should need less than 100 MB of disk for
application code. Centralized disk management makes it easier
to manage the disk space allocated to user directories.
Additional disk space will need to be reserved for expanding
user disk space, but much less space is required than with
multiple PC's with local hard disks.
Is the Windows Client an HP-designed and manufactured product?
Yes, the Windows Client was designed and is being manufactured
in Roseville, California. Your customers can be assured that
the same conservative design philosophy and attention to
quality in manufacturing that has exemplified HP products
exists with the Windows Client. Distribution will be through
NADO in Roseville for the Americas and Asia/Pacific, through
PCID for Europe, and through LADO for Latin America.
