List Hosting General Information
Introduction
This page describes the hosting and software utilised by the various mailing lists that Codify hosts as people have asked about this from time to time.
Hardware Platform
Codify utilises Dell 2950 or R710 servers as a standard workhorse for customer workloads.
Processor
These servers are ordered with the dual processors being fastest available L-series XEON processors available at the time of ordering. This gives us the benefit of a lot of CPU power while being very economical to run and helping us stay within our data centre budgets.
RAM
16 GB FB ECC DRAM
Disk Subsystem
2TB of 15K RPM SAS in RAID-5
Other miscellaneous factoids
- Redundant Catalyst switches for uplink.
- The server has a 100 mbps uplink to the datacentre which in turn has 220 mbps of Internet backhaul to diverse Internet providers via BGP routing.
- 100 mbps dedicated private VLAN between the primary data centre and Pipe Networks' DC2 in Creek Street for over-the-wire off-site back-ups.
- Separate production data network for Internet facing traffic.
- Separate out-of-band network for management via VPN+RDP or DRAC5 (remote BIOS flashing etc).
- Separate out-of-band network for inter-data centre backups
- Redundant power supplies with A+B rundant UPS backed power backed in turn by a diesel generator.
- Network KVM for hands on management.
Virtualisation Platform
As of 3rd of December 2008, with ozmoss, ozsilverlight and oztfs placed under Codify's care, all of the lists were migrated to a dedicated "Microsoft Community VM" (ausdotnet previously was hosted on the VM that runs this web site). The guest VM runs CentOS on Windows Server 2008 + Hyper-V on the host hardware platform mentioned above.
List Server Software
The lists themselves are run using Mailman and Postfix on CentOS Linux. The CentOS install is a guest on a Windows + Hyper-V virtualisation host.
