GPFS and HA
 
GPFS has now the so called protocol nodes which do provide a HA environment for
NFS and SAMBA.
I assume its based on the CTDB since the CTDB is currently supporting a few
protocols already.*
 
What i would like to see is a generic HA interface using GPFS. It could be based
on the CTDB , native GPFS callbacks or any service providing HA functionality
based on a clustered FS.
Such a service would allow - only with minor extentions - to make almost any
service (Oracle,DB2,FTP,SSH,NFS,CRON,TSM  a.s.o )  HA.
So IMHO the current approach is a little bit shortsighted.
 
 
GPFS and System i
 I looking forward the day we have a SQL interface/API to GPFS. Thus storing DB
objects natively on a GPFS thus not using any kind of addional DB files.
Now if you would have such an interface what about a general modern language
which supportr SQL and is multi node runable ?
 
Who knows ... Maybe the AS/400 gets reinvented
 
cheers
