The way computers are used in most
small-and medium-sized organizations is often the result of circumstance more than careful
planning. Years ago, PCs began to creep in one by one. Eventually, they were lashed
together into LANs. A few advanced PC users created special applications around
spreadsheets. In some cases, packaged client/server applications may have been added as
well. Since then PCs have matured into powerful tools. Few organizations can resist using
them. The number and importance of tasks that run on PCs seem to keep increasing. The
price of PC hardware continues to drop, but the real cost of owning PCs keeps increasing
as a result of their huge appetite for technical support. Industry analysts have
documented the hidden costs of PC ownership. They estimate that each PC used in business
costs over $10,000 per year, as a result of all the support needed. Large organizations
can afford PC help-desks, most smaller organizations must limit what they do or live with
associated cost and complexity.
Smaller organizations yearn for
technology that is easier to manage. What they want does not sound unreasonable:
- Lower total cost, especially where PCs are involved.
- Less need for technical expertise.
- Hardware and software that rarely fails.
- Rapid and complete recovery when failures do occur.
- Fewer things to buy, integrate, support and
understand.
- Tight security that is easy to manage.
- Performance that appears instantaneous.
- Use of the internet without excessive cost, risk or
effort.
- Less frequent hardware and software upgrades.
- Ability to avoid conversions from outdated products.
The AS/400e from IBM is positioned
as a server platform to satisfy the needs of small and medium-sized organizations. Server
computers don't have the high visibility of PCs. Small-and medium-sized organizations
usually choose one of three types of servers: PC, Unix, or AS/400e. Each type has
advantages and disadvantages. Making the best choice is important, but not simple. One
type of server may not always be the right answer. The most visible way in which the
AS/400e has become attractive for smaller organizations is the introduction of the new
e-server 170 (also referred to as AS/400e server 170).
Role of AS/400e
The enhanced AS/400e offer some advantages for small-and medium-sized organizations when
compared with PC-or Unix-based servers:
- Less technical expertise is needed.
- The total cost of ownership is usually lower.
- There are more applications from which to select.
- A smaller number of servers is needed-often only one.
- More system management functions are automated.
- Full-function internet capability is now available.
- NT applications can now run on an Intel co-processor
inside AS/400e.
- Leading development environments, like Java, are
supported.
All these advantage are important,
but one outweighs all other and that is AS/400e requires less effort by technicians and
administrators. The need for constant attention is a serious disadvantage that NT and Unix
share as servers for smaller organizations. It is especially difficult today to develop
and keep technical people with NT skills. Rapid growth in demand for NT has created a
severe skills shortage.
Another important advantage of
AS/400e is that 8,000 IBM Business Partners have written over 30,000 software application
packages for AS/400e compared to about 2,000 applications for NT server running on the
Intel platform. Since robust business applications for the Intel platform are hard to come
by, many Intel-based shops hire programmers to write custom applications, involving time
and money. With so many packaged applications to choose from, businesses that use AS/400e
computers can purchase a package and deploy it much faster, with fewer people and less
cost than a business writing its own applications. With the advent of Domino Server on
AS/400e, thousands of additional applications will be available to run on AS/400e.
Ironically, requiring less
technical expertise is not always seen as an advantage. To technology experts, a computer
that needs less of their skill is not always viewed as a good thing.
Lowering Cost: Most
successful organizations are good at controlling costs. Part of being good is being able
to identify the best deal when different options are not priced the same way. Numerous
independent evaluations have shown AS/400 to offer low total cost of ownership in the
past. There are many reasons why this is the case even though the base price of AS/400e
hardware remains higher than Unix or PC servers. The factors that offset the hardware
price difference include:
- Only one AS/400e server is usually needed at each
location. PC or Unix servers are commonly linked together because a different server is
required to run each major application.
- Less effort is needed to operate and administer
AS/400e systems. As the number of locations increases, the savings grow even more since
one operator at a central location can often control a large number of remote AS/400e
servers.
- When programs running on AS/400e servers fail,
recovery is usually automatic and there is rarely a need to reload the system.
- Fewer technical experts are needed.
- AS/400e servers do not require replacement as quickly
as PC or Unix servers.
AS/400e Hardware Advantage: The
new e-server 170 is cost effective for two reasons. First, IBM has taken a gamble by
offering low-end AS/400e hardware-with a very powerful processor-at a low price. Second,
the switch to 64-bit RISC processors is paying off. Applications running on AS/400e are
automatically able to make full use of 64-bit processing. This includes applications
originally written for Unix that are offered on AS/400e. In the 10 years since AS/400 was
introduced, customers have never been required to change their application software. Since
application software is often the most expensive part of the information technology
investment, the fact that AS/400 customers have never been required to change their
software represents a significant savings-especially when hardware upgrades are needed.

In contrast, today's PC servers
offer 32-bit processing technology. Intel is developing a 64-bit processor chip called
Merced, which will not be available until sometime in 1999. When it does become available,
Merced will require NT release 5.0 (which is also under development). Independent software
vendors, writing packaged applications for NT server, as well as customers who have
developed their own in-house application, will need to rewrite them in order to take
advantage of 64-bit processing when Merced does become available. This will be expensive
in terms of resources and time.
By the time Merced and NT 5.0 are
available in servers, a next generation of AS/400e processor, called Northstar, will be
available. Users buying the AS/400e server 170 today will be able to have Northstar
processors installed when they become available. Few PC servers being sold today can make
this offer to customers when Merced becomes available. Customers that desire PC servers
with the new Merced processor will have to purchase new PC servers. Customers that
purchase the e-server 170 will not have to purchase new AS/400 hardware. AS/400e server
170s are likely to retain their value much longer than Intel-based servers. The processor
technology advantage that AS/400e has will continue for some time.
