SVM new features

solaris_enginee

Sun's Volume Manager has evolved a lot over the years. In name
alone, it was once known as ODS (OnLine Disk Suite), then
SDS (Solstice Disk Suite), then SLVM (Logical Volume Manager),
and now in Solaris 9, it is called SVM.

In Solaris 9, it is literally built-in. If you install even the basic
Solaris
OS (the user collection) you get SVM, for free, integrated with the
OS. It supports soft partitions and device IDs (two of the "must have"
features that many admins have been screaming for) and a new mgmt
interface. And the built-in/free UFS+ filesystem supports journaling
(aka: logging), QuickIO-like performance (we relaxed some POSIX
rules back in Solaris 8, and added some other performance tricks,
similar to QuickIO), and online filesystem growth.
