Hi,
I've installed NC core yesterday on a X4500 and have a few questions:
(1) It's nice to see that ZFS can be used for the system disk. This
system can only boot from two disks (c6t{0,4}d0). For this first time
installation I used both these disks with Autopartitioning. Would it be
possible - in principle - to have the system on a large raidz2 pool? How
would I tell grub to install the MBR into the right place?
(2) Is it possible to install Nexenta via the serial console
(IPMI/BMC/ILOM)?
(3) I've only tried a single threded bonnie++ run yesterday, however, NC
seems to be (sometimes much) slower than an identical box with Solaris10:
This is the result from s01 (Solaris10):

Especially the block read is by far slower.
(4) Final question for now: Is it possible to "clone" a Nexenta
installation to another box, or is there an automatic way to install
Nexenta?
Thanks a lot for possible answers
Carsten
