Filesystems, Disks and Memory

Hi.

I've been working with UNIX/Linux for several years, but never in a VSF environment where I actually got to use any of it.

I downloaded the basic package for free (Don't worry, Symantec now allows for this for limited use) and intend to try this out on Linux and Solaris (also not my strongest area, as I have been more familiar with Red Hat and SUSE as well as HP-UX).

If anybody has any information on where to best learn Veritas File system management, I would appreciate it. As it is also most often used on Solaris, I would also appreciate any information on that too.

why use vxvm and vxfs when solaris comes with slvm and ZFS? for infos about solaris and volume management go to http://docs.sun.com and look for the solaris documentation.
the vxvm and vxfs documentation can be downloadad at the symantec website...

Well, I understand about ZFS and in many cases, I have heard, right or wrong, and from my experience, that ZFS is "not ready for prime time" in every area.

I had a major project on a smalltalk app/db server where ZFS was used and a lot of tuning had to be done. The former "Storage Guy" had set up that machine using ZFS defaults and the memory allocation was screwy as well as performance that was 50% or less than that of UFS on both Solaris 9 and Solaris 10 machines with UFS.

I had to do a few weeks of research and modify the ARC buffer sizes as well as set the read block size to 8K instead of the default 128K (this works for Oracle and other 8K read dbs as well)

However, on many sites, I have seen Solaris 7, 8 and 9 as well as 10. While I will be working primarily on Solaris 10 x64 in a VMware virtual machine, I would appreciate the opportunity to learn VxFS and VxVM as well as VCS if possible, at some point.

If you have any sites besides the manufacturers, I would appreciate. Even if you have links to the ones for Veritas/Symantec, as I was unable to find anything more than a few PDFs that describe overviews instead of instruction.


Thanks in advance,
Mark
