hi guys, I have a job interview next week and have been asked to make a presentation on the following topic
The computerised Library System at a university runs on a number of servers, two of which are essential to the service. These two standalone servers provide different parts of the service and are each single points of failure. The two servers and the applications running on them are: ? Sun Fire V240 ? 2x1503 MHZ UltraSPARC III CPUs ? 8GB memory ? 4 years old ? Solaris 9 ? Oracle 10.2 ? MySQL 4.1.9-standard ? applications to access library databse. ? Sun Fire V490 ? 2x1350 MHZ UltraSPARC IV CPUs ? 8GB memory ? 4 years old ? Solaris 8 ? Sysbase 12.0 ? application to access university portal. Storage is provided on a dual site Storage Area Network. We must introduce high availability into our increasingly important Library Systems so we wish to replace these servers with new hardware and a configuration which will give us high availability and will minimise future down time. Suggest how this may be achieved based on the following assumptions: ? The new high availability system will be hosted on Sun servers running Solaris 10. ? We have two data centres in separate locations with fast fibre connections. ? Data storage will continue to be provided from a two site SAN. please, please help anything at all would be greatly appreciated thanks, Rosie -- This message posted from opensolaris.org
