RE: Disk storage - iSeries/Windows/UNIX

["Graap, Ken" <keg@xxxxxxxxxxxxx>]

The more I think about this why would it even matter what the block size is
for an iSeries controlled disk? 

The "virtual" disk space or REAL disk allocated to a UNIX partition would be
formatted and controlled by the OS running in that parturition (AIX or
Linux). 

As for Windows... A virtual disk would be allocated to an xSeries system
(IBM's integrated Intel based server) and this disk would be formatted by
Windows. For example, as an FAT32 disk or a NTFS disk. 

How the actual data is stored on the physical disk within the disk subsystem
on the iSeries (AS400) wouldn't matter...RIGHT ????  Because direct data
sharing of these virtual storage spaces is not part of this equation. These
"virtual" disks would not be shared disk. That is they wouldn't be disk that
the iSeries could read directly. The iSeries could backup the storage space
though, because it is known to OS400 as an "object". OS400 could also do
file level saves of Windows space because it participates in SMB as a client
or a server. Sharing between UNIX storage spaces and other OS's could be
done using SAMBA or NFS... 

What do you think ????

When creating most filesystems in linux you can specify the blocksize 
(linux has several filesystems it can use).  Look at the man page for the 
filesystem create command you are interested in (i.e. 'man mkfs.xfs' or 
'man mkfs.ext3').
