110 Sun Fire V100 Server User’s Guide • December 2001
How many Sun Fire V100 servers can be put in a standard 19-inch rack?
Physically and electrically, you can put up to 40 Sun Fire V100 servers into a
standard 19-inch rack with two 20-amp circuits. However, a more practical
deployment would be 32 servers in a rack with termservers, network gear, and
additional power strips.
Where do I connect my monitor, keyboard, and mouse?
Because the Sun Fire V100 server has been designed as a rack-mount compute
element, there is no keyboard, mouse or parallel port on the Sun Fire V100 server. To
manage the server, you have to connect to the console (ttya) port and manage via a
console connection. Two USB ports are available for adding a keyboard and/or
mouse if needed.
What is ASR?
Automatic Server Restart (ASR) is a feature of Lights-Out Management that can
automatically restart the Sun Fire V100 server in the event of the operating system
locking up. The feature can be turned on or off and is fully configurable. See
“Configuring Automatic Server Restart” on page 73 for more details.
Why are two Ethernet 10/100 ports included with the Sun Fire V100
server?
The most common deployment for a server in use at a service provider is to have
two physical network connections to each server. One is for the production network,
the other for the administrative or backup network. Each is a separate physical port,
usually connecting to separate network switches. This provides better redundancy,
in case of error, and increased isolation, for security.
Why does the server use RJ-45 instead of DB-9 or DB-25 connectors for
the serial port?
The Sun Fire V100 server uses RJ-45 connectors for its serial ports because these
connectors best suit service providers’ systems. With RJ-45 connectors, you can use
standard Category 5 network cables without needing any extra adaptors. With DB-9
or DB-25 connectors, you would need to use extra adaptors to use the standard
Category 5 network cable.
