Hi,
We are looking to build a new machine for a big PG database.
We were wondering if a machine with 5 scsi-disks would perform better
if we use a hardware raid 5 controller or if we would go for the
clustering in PG.
If we cluster in PG, do we have redundancy on the data like in a RAID 5
?
First concern is performance, not redundancy (we can do that a
different way because all data comes from upload files)
Met vriendelijke groeten,
Bien à vous,
Kind regards,
Yves Vindevogel
