Revision 4: December 2000
December saw a few minor improvements, primarily the addition of a new development
|Dual PIII-800, 256Mb RAM|
|30Gb IDE hard drive, IDE DVD|
Along with the workstation came the first LCD monitor, a ViewSonic
VP181, using DVI directly from the video card - all digital, no stops.
Two more APC
1U 450VA UPS added - one for the workstation, the other for the network
hardware, after experiencing a power outage and watching all the servers work
happily along, with no network.
An SMC 8
port switch was added to the top of the rack, the DSL modem routed through
it. This provided a simple way to get at the Internet directly - the DSL service
I purchased provides five "real" IPs, the LinkSys router uses one of
A second LCD panel, this one a ViewSonic
VG151 was installed for the secondary console, along with a small wireless
keyboard. The VG151 was mounted to an ICW
Ultra 210 swing arm, which allowed it to be swung around nearly 180 degrees,
so that the secondary console was usable both from in front of the rack and at
the main station. The swing arm is actually mounted to the rack using a
Also, it seemed like a good time to take some pictures of the rack:
||Here's a top-to-bottom look at the rack as of December 2000.
The desk is on the left, and the VG151 LCD panel on the swing arm is
turned to face the rack. This is the fullest the rack had been to date!
||Close up of the file server (Cartman). The bottom 4U
case is the drive array, there are eight caddies, only four are filled
with 80Gb Maxtor IDE drives. This solution isn't working reliably because
the IDE cables are too long. The second case is the computer itself, with
an APC 1U UPS above it.
||SQL Server (Chef) and Web Server (Stan) - both in 4U cases,
each has its own UPS. On the right of the rack is a vertical power strip.
On the left is a finger duct cable channel - all non-AC wires run in the
||The top bit of the Web Server (Stan) is visible. Above Stan
is the Kyle, the Exchange Server (I should have called it Mr. Hanky, it is
a piece of shit). Above that is the main development workstation, a dual
800 Mhz PIII, 256Mb RAM running Windows 2000.
||The two UPSes at the bottom cover the development
workstation and the networking hardware. Above that is the Belkin 2x8
switch box - up to eight computers, with two consoles. Then there is one
of two Ortronics horizontal cable channels, between which is the patch
panel for the house - each room is wired to this panel. On the right side
of the panel is the phone line and ADSL line connectors.
||Top part of the rack - the networking gear. The 16 port SMC
switch is on the bottom, its cables run into the cable channel just above
the patch panel. The shelf holds a fax modem, cable modem and ADSL modem,
along with two LinkSys NAT routers (one for each Internet connection) and
a wireless gateway for 802.11b wireless networking. At the top is an eight
port switch and cable channel - this is connected to the ADSL modem. My
DSL service gives me five "real" IPs, only one of which is used
by the LinkSys router. The eight port lets me access the Internet directly
using the other IPs if I wish, without going through the router.
Problems with this revision:
|Very low on space: 5Us left!|
|Need a backup solution, preferably a black, rack mount backup solution.|
