[gpfsug-discuss] GPFS and High Availability , GPFS and the System i (AS/400 )

[Scott Fadden]

It is probably not what you are looking for, but I did implement a two node
HA solution using callbacks for SNMP. You could do something like that in
the near term.

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
