Operational Maturity part two - Belts and braces
Following on from the previous post from our guest blogger Nic Blank on operational maturity and storage, I'd like to call out another area in operational maturity – Transporting and Routing Mail. Exchange 2010's transport High Availability model is rather simple – add more HUB servers, and they become redundant, shadow transport ensures mail delivery and so on. However, this requires some planning. Shadow transport is a great feature; it really is. It allows the failure of a Hub Transport server without the loss of messages in transit. However; two caveats come to mind:
- You need more than one HUB Transport server in a given Active Directory site in order for Hub Transport servers to load balance mail traffic
- You need an Exchange Server on either side of the Hub Transport server – either an edge or another Hub transport server on either side OR a mail server as the originator or destination.
- Simple mail testing tools that send mail between two mailboxes at nominated points in the org.
- Free tools and or Scripts capable of pinging servers at regular intervals, checking for service availability, etc
More tools or scripts to monitor for disk availability and disk free space usage
