Why many MCSEs won't learn Linux

Paul has responded to MCSE mike. Checkout my stand on Linux admin vs Microsoft Windows admin.

There are few basic principals under UNIX and Linux. Any MCSE must understand and follow them.

a) Everything is a file - Including your hardware.

b) All server / desktop configuration stored in text files - /etc, /usr/local/etc and ~/.dot-files. So learn to edit and search text files. Learn basis of grep, awk and sed along with vi. Same way all errors are logged in a text file located at /var/log/ directory

c) One small utility performs one single task at a time - Typical Linux box may have 2000-4000 command installed. Each command provides a single functionality.

d) Linux / UNIX is designed for simplicity - Add complexity only where you must.

e) Filters - Ability to chain programs together to perform complex tasks.

g) Interactive commands and dialog boxes are rare in UNIX / Linux - Learn to use commands, command line arguments and man pages.

Let the flame war begun ;)

Intel has just released source code for Fibre Channel over Ethernet (FCoE). It provides some Fibre Channel protocol processing as well as the encapsulation of FC frames within Ethernet packets. FCoE will allow systems with an Ethernet adapter and a Fibre Channel Forwarder to login to a Fibre Channel fabric (the FCF is a "gateway" that bridges the LAN and the SAN). That fabric login was previously reserved exclusively for Fibre Channel HBAs. This technology reduces complexity in the data center by aiding network convergence. It is targeted for 10Gps Ethernet NICs but will work on any Ethernet NIC supporting pause frames. Intel will provide a Fibre Channel protocol processing module as well as an Ethernet based transport module. The Open-FC module acts as a LLD for SCSI and the Open-FCoE transport uses net_device to send and receive packets.

This is good news. I think one can compare bandwidth and throughput for copper and fiber Ethernet. If you are going to use copper you need to stay within 15m of the switch. This solution will try to bring down cost. One can connect to 8-10 server to central database server with 10G and there could be few more applications.
