Site Hosting

Original Rack

There have been quite a few updates to the hosting solution for this site, which is hosted locally in my house, from the above setup, in a small comms rack, to a new 22U half rack, with some hardware upgrades to come.

Core Switch Disconnected

Core switch here has been removed, with the rest of the core network equipment. The site was kept online by a direct connection into the gateway to the intertubes.

New 22U rack, with the core switch, FC switch & management & monitoring server installed.

As I had no rack rails to start with, the servers were placed on the top of the rack to start off, here is the Dell PowerEdge 860 pfSense core router installed, with the initial switch wiring to get the internal core network back online. This machine load balances two connections for an aggregated bandwidth of 140MB/s downstream & 15MB/s upstream.
The tower server behind is the NAS unit that runs the backups of the main & auxiliary webservers.

Almost Done

Still with no rack kits, all the servers are placed on top of the rack, before final installation. This allows running of the network before the rest of the equipment was installed.

The main server & aux server are HP ProLiant DL380 G3 servers, with redundant network connections.

Still to arrive are the final rack kits for the servers & a set of HP BL20p Blade servers, which will be running the sites in the future.

Stay tuned for more updates as they happen!

Cisco 2G Fibre Channel SFP Module

Here is a 2Gbit Fibre Channel transceiver from Cisco Systems in SFP module format.

Here the shield has been removed from the bottom of the module (it just clips off). The bottom of the PCB can be seen, with the copper interface on the left & the rubber boots over the photodiode & 850 nm laser on the right.

Here the PCB has been completely removed from the frame, the fibre ends slide into the rubber tubes on the right.

Top of the PCB, showing the chipset. There are a pair of adjustment pots under some glue, next to the chipset, presumably for adjusting laser power & receive sensitivity. The laser diode & photodiode are inside the soldered cans on the right hand side of the board, with the optics required to couple the 850nm near-IR light into the fibre.
