Filesystems, Disks and Memory

guys,
pls help me out.
i hv good idea in redhat linux
in what areas i need 2 concentrate 2 mk me much
familiar with that of solaris.
pls let me know the major diff found in these two
os.

unix is pretty much the same across flavors.

I would suggest making sure you know UNIX very well. So the differences in platform wont matter as much and your learning curve will be smaller. IF you are an expert in one flavor, learning another is not that hard.



With that said, most flavors differ in how they handle disk management and device definitions.

I am not familiar with Redhat, but between Solaris and HPUX, some of the main differences are, but not limited to:

1) Filesystem layout is slightly different.
2) some system files are named differently.
3) devices are named and differently, with additional different directory structure.
4) Solaris primarily uses Veritas VXVM and FS which is a huge improvement on many volume (disk) managers and filesystem managers. HPUX uses mostly LVM (included)but most run JFS online which is a lesser brother to Veritas and can also run the Veritas product very well.
