THE NETWORK
The Snakebite network is currently comprised of three sites: Server Central (SC), Michigan State University - Computer Science & Engineering (MSU-CSE) and Michigan State University - Genomics & Evolutionary Development (MSU-GED).
Server Naming Conventions
The trusty ol’ periodic table was used as a basis for naming development servers at MSU. The last octet of a server’s IP address corresponds to the numerical index of an element in the periodic table (which the server will be named after). Exclusions are hydrogen and helium (x.x.x.1 and x.x.x.2) as they’ll typically be used as the gateway or DNS for a given subnet. General rule of thumb: if a server is named after an element, it’ll be accessible via your normal Snakebite credentials. If it’s not (i.e. cse-rodc-1), it won’t be.
Virtualisation
Excluding the FreeBSD jail and Hyper-V instances hosted at Server Central, none of the hosts listed below are virtualised — everything represents a physical machine. That being said, virtualisation is going to play a very important role in Snakebite going forward, and many servers have already been configured specifically as virtualisation hosts, as per the VH role indicators. Virtualisation will allow us to provide many more platforms to developers than if we were limited to physical machines alone. One of our goals is to have 32-bit and 64-bit offerings of every major OS released over the past 2-3 years, coupled with bleeding edge snapshots for those that want to get a taste of what’s to come in the following 2-3 years. Leveraging virtualisation is key to achieving this goal without requiring excessive hardware.
Role Legend
| Key | Name | Description |
|---|---|---|
| G | General Purpose | Build/development/test server; should have full development environment available (compiler etc). |
| CA | Certificate Authority | Trusted/intermediate CA for snakebite.org |
| DC | Domain Controller | Either a writable or RO domain controller in the snakebite.org domain or subdomain. DCs provide DNS, NIS and sometimes DHCP Services to their respective subnets. |
| DB | Database Server | SQL Server, Oracle, DB2, MySQL, Postgres. |
| FS | File Server | Unix home drives and shared NFS areas provided by Solaris and ZFS. Windows uses DFS. |
| NS | Network Server | Provides some form of network service; ssh gateway, httpd, varnish proxy, VPN/IPSEC, RRAS, etc. |
| TS | Terminal Server | Developer desktops (Visual Studio etc preconfigured) via Terminal Services. Windows only. |
| VH | Virtualisation Host | Depending on the OS, will either be Xen, VirtualBox or Hyper-V*. |
[*]:No particular reason for not using VMWare, we just don’t have a license for it and it was too expensive to buy one considering Xen, VirtualBox and Hyper-V were all free. VMWare’s more than welcome to donate any licenses to Snakebite.+
NB: The roles allocated to servers below are not final and may change over time.
Server Central - Chicago Data Center
Site ID: SC
Location: Server Central, Chicago, IL
Primary Contact: Trent Nelson
Domain: snakebite.org
Subnet(s): 66.225.202.65/24, 72.102.26.65/24, 10.0.3.0/24
We have two servers in Server Central’s Chicago data center; one running FreeBSD 7.0-STABLE and the other running Windows Server 2008 x64. The FreeBSD box hosts the fatal.snakebite.org jail that serves this site as well as svn.snakebite.org. We make extensive use of the Hyper-V technology available in Windows Server 2008 x64 to virtualise our core infrastructure roles (i.e. Active Directory, Certificate Authority, VPN, DNS, etc). Unlike the servers hosted at MSU that are geared specifically towards development, these servers form our core infrastructure and as such, are not accessible with normal Snakebite accounts.
