@IBM 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 Hajo Reference: * https://ctdb.samba.org/documentation.html
