Splitting an IRIS db to multiple drives
I'm looking for a way to have an IRIS db distributed over several (hw) drives.
Without touching the internal data structures (e.g. mapping) !
Are there any options in file systems to achieve this "splitting" or "appending" ?
Historic background:
- Once upon a time CPUs worked on 32 bit
- Files could mostly not be larger than 2 GB
- And Caché had a (forgotten) option to EXTEND a db to a next file of another 2 GB max. and a next ...
This EXTENT was excellently suited to move fresh and active data
to a faster spindle for more performance.
[ oh dear!
Spindles are gone meanwhile with SSD and Virtual Storage Arrays
they only survived in museums and old fairy tales to sleep 100 years ]
Death to extents :)
I work in Unix where LVM and mount points would make this easy but it looks like Windows has mount points.
