There is both software RAID support and journaled file systems - and with
certain FLASH type storage media, it might be possible to use either or
What is it that you have as requirements?
certain RAID configurations can survive the failure of a device - and may
even survive the failure of more than one device if enough spares are
available along with the time to re-build the RAID array elapses between
Journalling file systems are better at surviving power failures -
failures of the whole system as opposed to failure of a single drive
Take a look at JFFS (Journalling Flash File System)

I suppose the easiest way is get a PCI-IDE-Raid adapter card and hook
several IDE-Flash memory devices (cards or boxes) to same.
Of course there are software solutions, too.
A journalling file system (Reiser, XFS or EXT3) will help, too.

quick question - working on a automated solaris 10 build for our
customers, and they support a number of different HBA's and Storage
arrays - I wonder if anyone has come across a good reference point for
suggested Kernel Tunables for storage within solaris
for some of detail - HBA's are a mix of the usual suspects from Emulex
Storage arrays are (again) usual suspects from EMC / HDS etc.
any words of wisdom would be greatfully recieved.
