Based on discussions with a number of individuals, Linux Online developed an implementation for our internet site that we hope will carry us for the next two or three years. Outlined below are the systems we have built and a description of how you are accessing our site.

We would like to acknowledge the contributions made by the following vendors, without whom this would not have been possible. Without exception, we believe that each of these vendors provide high quality equipment; equipment that we trust to handle our most critical applications. We are confident that you will find the same level of quality and support for your computing needs.

	Secondary DNS service
	Symmetra 8kVA + extender frame
	256M PC133 SDRAM/ECC DIMMs
	Ecrix VXA tape drives
	Ultrastor hard drives
	Intel EtherExpress Pro/100 network cards
	Chassis and technical assistance
	Metalist & Barracuda hard drives
	Motherboards and chassis
	Pentium III 1GHz & 1.2GHz CPUs

Internet service (dual T1 -- 3.088 megabits/sec) is purchased from AT&T Canada and is provided via their POP in Ottawa, Ontario, Canada. This is connected via Bell Canada into a Cisco router and a 10Mb/s ethernet to the Pentium 233 MMX machine known as router.invlogic.com. The router is connected by a Linksys EtherFast 10/100 switch to the rest of the network. Advanced Internet Technologies (AIT) provides secondary DNS service from their location in North Carolina, USA.

The two web servers and one database server are identical. Dual Pentium III 1GHz, SuperMicro P3TDE6-G motherboards, SC750-A chassis, 1Gb of PC133 RAM dual Seagate 18G Barracuda drives using software RAID1 (mirroring), Intel EtherExpress Pro/100 ethernet cards, Toshiba 40X SCSI CDRom and Ecrix VXA-1 tape drives.

Identical in most respects to the systems above is the server for ftp.linux.org. Using an SC801-A chassis and mounting 10 IBM Ultrastor 36 Gb drives in addition to dual 9G Medalist drives providing the root partition, this system is intended to mirror the Linux distributions, archive sites, etc as it becomes available on the net. Backups are provided by an Ecrix VXA 999Gb tape library. Currently this system is offline due to hardware failures and limited bandwidth. It needs more drive space and better net access to be useful.

Our CVS repository and development testing servers are both on Dual Pentium II 500MHz/512k cache systems with 1Gb of PC133 RAM, dual Seagate 18G drives with VXA-1 tape drives providing backup. There are also 3 other similar servers providing non-essential services such as mail processing, fax reception and transmission, etc. There are 4 workstations of various configurations using most of the same components above.

In order to enhance the reliability of the services provided by Linux Online, we have installed a UPS supplied by American Power Conversion. The new Symmetra 8kVA unit provides regulated power to all the computer and support equipment on our site. The combination of the main UPS and an extention frame will provide us with 3 hours of battery power in the event of a local power disturbance.
