Fore Marconi ESX-4800 Backbone Switch
Posted: Thu Apr 08, 2004 11:18 am
KalNet is pleased to report the addition of a new Switch. This switch is a Fore Marconi ESX-4800 Backbone Switch. This rackmount switch comes with the following modules installed:
1-ESX-4800-48TX 48 port 10/100 module
1-ESX-4800-24TX 24 port 10/100 with 2 port 2OC12MM OC-12c MMF module,
1-ESX-4800-3SX24FX 3 port 1000SX with 24 port 100FX Fibre module
1-ESX-4800-2TX44FX 2 port 10/100 with 44 port 100FX Fibre module.
There are 4 open bays on this unit.
Also all 4 power regulator modules come with it as well.
There is a few to many fiber ports for my uses, but i figure I will see thous parts off and buy more 48 port modules.
This is a review of th Unit:
I have to run to class, I will post pic's later.

This is a review of th Unit:
The ESX-4800 is the big brother of the ESX-2400. The huge chassis can take up to 8 modules with up to 8 x 48 ports 10/100 Mbit/s. The 4800 switchfabric-mainboards have installed both busses on the backplane to transport up to 20 Gigabit/s of internal data transfer. However, the 4800 modules are not interchangeble with the 2400 modules.
In the lower part of the 4800 chassis there is a "Lucent Power System" chassis with 4 power modules, the experts say rectifiers. The power suply cage has two 120/230 Volt main plugs for redundant operation on two Unint.PowerSupplies.
Each of the 8 ESX-4800 switch modules are independantly working, if power is supplied. There is no main fabric like the most competitors have. So the 4800 ist totally redundant.
The data bus on the backplane is designed for 2 x 10 Gigabit/s and the hardware is designed for up to 36 giga packets per second (pps). This is an enormous switching power.
We will link to a power "Data transmission test", that has been done in 1999, to check some competitors by their markting papers and the real truth. There was a test environment, simulating a number of workstations close to running at the limits.
Within this test the ESX-4800 has moved 18 million packets per second, which was really impressive and the allmost best in this test. There has been a loss 10 packets out of 46 million 1518 byte packets. There was a 46 Gigabit stream with over 68 million 64 byte packet/sec based on layer 4 TCP traffic. The tester said, that this was really impressive.
