Raid 1+0 ?

My cutomer wants to set up a OS/apps server with two 72GB drives
configured with RAID 1+0. The way I understand RAID 1+0 is
that if there was a drive failure the whole OS/apps is lost because you
actually need at least 4 drives to set up a RAID 1+0 by splitting
them up into two arrays. Am I right or am I wrong?

Thanks.

NAME
lsimega - SCSI HBA driver for LSI MegaRAID 320-2x SCSI RAID Controller The lsimega SCSI RAID host bus adapter driver is a SCSA-compliant nexus driver that supports LSI MegaRAID 320-2x SCSI RAID devices. The lsimega driver supports standard functions provided by the SCSA interface, including RAID disk I/O and passthrough I/O to support SCSI tape and CDROM. DRIVER CONFIGURATION
The lsimega.conf file contains no user configurable parameters. Please configure your hardware through BIOS. The LSI MegaRAID 320-2x device can support up to 40 logic drivers. Note that BIOS numbers the logic drives as 1 through 40, however in Solaris these drives are numbered from 0 to 39.
