Understanding Oracle blocks and UNIX blocks re. redos

Hi,

Can someone please explain the relationship between Oracle blocks and UNIX blocks?
Say you set block size in initora to 2048. When Oracle goes to read a file, does it request of UNIX "x" blocks to be read, or "y" bytes?
Same question when Oracle writes to a file...

I ask this so I can also understand the implication of using large-file-enabled filesytems (feature of AIX) with Oracle. For filesystems containing:
1. Data
2. Oracle dump directories and redo logs.

Thanks and Regards,
