CHANGE IN PROCESS
Congratulations to you and the Network Magazine team
for the nice cover feature 'Shopping for Servers' in
the February 2003 issue. I was Head-IT, at Mumbai Port
Trust (MbPT) (1989-97) and was responsible for installing
the Integrated Management Information System, including
the Vessel Traffic Management System (Automatic Ships
Surveillance System) for the entire Mumbai harbour.
Since then I have served as IT Consultant to various
ports (Cochin, Jawaharlal Nehru and Vizag), for deploying
their IT infrastructure. I am now Consultant to MbPT.
The hardware sizing process has undergone major change
in the last decade. You have clearly described various
factors involved in this operation. This article will
certainly help IS managers while selecting servers for
their organizations. However, in government organizations
like ports, the procurement of such servers is invariably
done through 'tendering'. This requires giving exact
specifications for the servers in the tender documents.
Earlier, the target server configuration was subjected
to 'customized benchmark tests' and suitable importance
was given to the test results during the technical evaluation.
This method was rather arbitrary and also time consuming.
Later in the nineties, the practice followed was to
specify the third-party benchmarks such as SPECint,
SPECfp and OLTP benchmarks such as TPCC ratings. The
audited TPCC ratings are no longer available for most
of the RISC-based servers today. In view of the above,
while procuring servers for MbPT recently, we selected
specific models based on detailed consultation with
OEMs like IBM, HP and SUN.

Dear Satish Nayak,
Thank you very much for appreciating our feature on
servers. It was interesting to read how the process
for procuring servers has evolved over time. Thank you
for sharing this with our readers. Since benchmarks
and tendering processes are seldom used when purchasing
servers (and other hardware), Network Magazine will
continue to offer advise on such matters, through more
such stories in the months ahead.
I'm working as a Deputy Engineer at BEL, Bangalore.
If we want to deploy a WLAN for military applications
do we need to use a military band or the regular ISM
Thilaga Lakshmi U.
Dear Thilaga Lakshmi U,
Thank you for your letter.
Since you are interested in WLAN security you can read
more on WLAN security at: www.iss.net/wireless/WLAN_FAQ.php
I had also forwarded your query to Colonel S.P. Kochhar
VSM, Col GS (Sigs and IT), Army War College, Mhow. Here
is his reply: The transmission band you want to use
depends on the requirements of the user organization,
which in turn will be dictated by security concerns.
If you are developing a system, then possibly you should
be working in the military band with necessary security.
Even in the ISM band there may be a requirement of the
right grade of security. However, a definite answer
can only be obtained from the RFP issued by the user.
