Only for the x2100 (and x2100m2). It's not that the hardware isn't
hot-swappable, it's that Solaris doesn't support it. If you run
Windows you will get hot swap.

I believe this also applies to the X2200 M2 as well. Essentially,
all the low-end x64 servers using SATA have Nvidia chipsets which
theoretically support Hot-swap of SATA; as noted, the Windows
drivers do support this feature, while the Solaris 10 drivers don't
(and, I don't know if there are plans to add this feature or not).
Personally, I've always been a bit nervous of using chipset-based
RAID and expecting Hot-swap to actually, particularly with SATA.
I've been bitten on various different (non-Sun) hardware trying
this, and it has made me gun-shy of thinking I can actually pull a
SATA drive while its mirror is still mounted...
Some of us don't give a damn about "chipset RAID" and want hotswap/
hotplug drives with SVM and/or ZFS.

Sun defines "hot plug" as a device which can be inserted or removed
without
causing damage or interruption to a running system, but which may
require
system administration. The vast majority of the disks Sun sells
are hot
pluggable.
To be clear: the X2100 drives are neither "hotswap" nor "hotplug"
under Solaris. Replacing a failed drive requires a reboot.
