Descriptive hostnames for server farm

Can someone give some insight to 4 fully qualified hostnames I can use for our new server setup. Assume the name of the website is helloworld.com We have the following:

• A Webserver
• A Failover Server
• A Storage Server
• A Database Server

From serverfault Jonathan Kushner

• • webserver: www.helloworld.com perhaprs?
  • failover: Failover for what, www? Then maybe www2.helloworld.com
  • Storage: storage.helloworld.com
  • database: db.helloworld.com
  Jonathan Kushner : Do I need the www for a hostname?

  Bart Silverstrim : Are you talking about names in DNS for the external network, or internal host names? You can add lots of "names" in DNS to refer to a server but have one name for the actual machine...
  From Kyle Brandt

• What is your expansion plan for the future?

  A generic set up that allows for scalability (more machines in the future) would look like this:

  web1.helloworld.com
  standby1.helloworld.com
  files1.helloworld.com
  db1.helloworld.com
  
  

  If the failover is for the web server, you may want to try: web2.helloworld.com or backup2.helloworld.com or something like that.

  (You may start things with 1 or 0.)

  Kyle Brandt : This is smarter, starting at 1 for everything :-)

  Dennis Williamson : You may not need it right away, but I'd pad those numbers with one or more leading zeros.

  briealeida : Dennis, you're so right. I often forget to do that with other stuff and then have to write a script to fix it. Thanks. :-).
