get 2 units - they're small. duplex online redo logs across them. no sense duplexing across a non-volatile and a physical disk.
Make sure that the UPS system that is powering the server notifies the Oracle Server.

An example scheme would be:

UPS on 30 minutes power remaining - SNMP pages SysAdmin.
20 minutes power remaining - pages DBA
15 minutes power remaining - shutdown immediate
8 minutes power remaining - shutdown abort if database is not closed
4 minutes power remaining - halt server OS
