Analysis of Requirements
China Life operates many servers that contain
a massive amount of important transaction
records and customer data which are maintained
by several network administrators. Real-time
centralized control and management as well
as data security are China Life's two major
goals. The main issue that administrators
must now contend with is how to go about
managing the massive database, associated
software applications and over a hundred
The aim of this solution is to enable several
administrators to concurrently manage over
a hundred servers. Each of them will be
able to independently take control of individual
servers as necessary.
II. System Outline
In China Life's server rooms there are
128 servers. The use of four Altusen KM0432
Matrix KVM Switches allow control to be
switched between all servers. Each KM0432
connects four console modules, enabling
four network administrators to independently
select the mainframe server they wish to
control. The KM0432 also connects 32 CPU
modules, and each mainframe server can connect
a CPU module over a Cat5 network cable.
This means 32 mainframe servers can be connected
to each KM0432, allowing them to be controlled.
China Life's hundred plus mainframe servers
were purchased over a long period of time
from a variety of suppliers, and their specifications
vary according to their intended function.
Altusen can provide different CPU modules
to match different types of servers. Examples
include the PS/2 CPU module (KA9120), SUN
CPU module (KA9130), SUN USB CPU module
(KA9131), serial devices CPU module (KA9140)
and the USB CPU module (KA9170). These allow
the purchasing requirements of different
servers to be met.
Can the KM0432's inter-switch connections
be made as a Daisy Chain or a Cascade to
create a centralized control structure?
In the China Life project, the Daisy Chain
approach was used. A dedicated connecting
cable was used to link up each switch's
daisy-chain port, and each KM0432 was also
connected to 32 mainframe servers using
CPU modules and Cat5 network cables. This
means that with just four KM0432s, this
arrangement allows all 128 mainframe servers
in the server rooms to be remotely controlled.
III. System Advantages
1. Excellent Hardware Expandability: Through
chaining, the KM0432 can control up to 2048
server mainframes of different specifications
(PC, Linux, Mac and Sun), so it has great
expandability and flexibility. The accessory
modules and Cat5 network cables allow the
KM0432, the mainframe server or the control
terminals to be as far as 150M apart. This
allows the optimal utilization of scattered
floor space. For China Life, even if new
servers are added in the future this additional
requirement will be easily met.
2. Cost-Effective: The KM0432 takes up
only 1U of rack space. Together with the
control terminal equipment space and costs
saved by chaining, this effectively decreases
China Life's expenditure on hardware and
3. High security level: 4 control consoles,
protected by 3 levels of passwords - Super
Administrator, Administrator and User. Data
security of China Life is therefore ensured.
There is no conflict even though data is
controlled by multiple users.
4. Intuitive Interface: can be easily managed
using hotkeys or OSD menu displays. No extra
5. Meets China Life's requirements for
high quality in products adopted for use.
Functions such as automatic signal adjustment,
firmware upgrades, Keep-Alive power outage
protection makes the Altusen KM0432 KVM
switch China Life's best partner for administering
