else who pointed me to

It was really interesting to hear that people are using SDS with the
A5000's. During the presentation I attended given by SUN UK last week I
was told quite emphatically that.

1 Only Volume Manager can be used with A5000
2 SUN do not recommend using RAID 5 on A5000 (apparently the performance
is quite poor)
3 There is nothing wrong with storing all your data, including the OS
filesystems, on the A5000
4 SUN also said that they intend to concentate on Volume Manager in
preference to SDS. The salesman stated that SUN didn't see a long term
future with SDS.

This information was expressed by one employee of SUN rather than a
corporate statement. However, at the time I had no reason to think that
this wasn't SUN's official view.

any comments welcome.
