Hi, Can we setup SDS without using special file-system like IBM's GPFS? If no then what are the options to choose for Sun Solaris. regards, Kamran

If you want to allocate chunks in a filesystem then a cluster filesystem like GPFS is required. Otherwise for raw chunks on a raw disk no filesystem is required generally. > If no > then what are the options to choose for Sun Solaris.

SDS only requires that the primary instance's disk chunks can be shared by both servers. If they are to be running on the same physical machine pretty much any storage will do whether filesystem or RAW or COOKED device files. If the SDS server will be on another machine then the chunks must be on a network sharable storage device like an NAS or SAN. Solaris is no impediment to setting up SDS secondary servers. Art Art S.

And that when a write is issued that the IO is not buff= ered in cache - that is the IO write must make it all the way to the physical device.
