Sun Solaris, OpenSolaris "When eWEEK Labs first reviewed Sun Microsystems' Solaris 10 early last year, we were impressed by the new facilities the operating system offered for better serving up applications and making the most of the SPARC and x86 hardware on which it runs. With this summer's Solaris 10 update, labeled 6/06, Sun has significantly improved on its already excellent operating system with the addition of the much-heralded Zettabyte File System."

> To be fair, this is "syntactic sugar", and the IBM admin app (I forget the name not have touched AIX in over 10 years) is certainly easy to use from a "green screen", Curses style application, but from the command line it's not as clean and clear as the ZFS command line.

SMIT (Systems Management Interface Tool, I think)

True, but there's also a lot of danger in it as well. It might give many home users a false sense of security..."I have two drives so it's okay if one fails"

RE[5]: ZFS vs. LVM+JFS2

I know both LVM/JFS(2) and ZFS, for me, the most significant features of ZFS are:

1) End-to-End Data Integrity.

2) Lightweight and near-zero-administration filesystems.

On the other hand, LVM/JFS2 has this most significant advantage: Predictable performance.

This is first due to non-COW (most other FS) v.s. COW (copy-on-write, like zfs).

Also, when you add a disk to a VG, you still have the control over how to use the disk for differnt LV/FS, whereas adding a disk to a zfs pool is really like adding a memory stick to the system.
Unfortunately, disk is not the same as memory, yet.
The difference in 'seek latency' is day and night.

There're many other differences, having different significance for different people.
It's all about "architectural choices and trade-offs".
