Hi all, I am going to have solaris 06/06, a database (postgresql), application server (tomcat or sun app. server) on x86, 2GB with max. 3 scsi (hardware raid possible) disks. There will be no e-mail or file serving.
The ratio of write/read operations to database is >=2 (and there is no other significant disk io). Block size of postgresql is default (I think it is 8K). Our application performance is bounded with database write (and then read) operations, so db write/read performance is important. I need redundancy in all over the system, not only for db data, but also os itself. Capacity efficieny is not that important (I can use full mirroring). Although I am not a sys.adm., I know some about raid levels and zfs, I want to ask your comments on disk configuration. Do you recommend mirroring or striping+some form of redundancy ? Specifically, raid 1 or raid 5 ? I am not going to use zfs as a root partition (since it is not possible in solaris officially yet), so I need some ufs partition. So, do you recommend me to use hardware raid or zfs ? If you recommend zfs, how can I configure it (I mean which disk/slice as zfs, and which disk/slice as ufs) since I only have 3 disks ? Thank you in advance.
