We will have the following configuration: - 4/370 as Server with: - 4 1-GByte SMD disks - 2 660-MByte SCSI disks - diskless clients Now i'm looking for an idea, how it may be possible to use two physical drives for one filesystem. I suppose, i need a virtual device driver, but SUN doesn't have this one (for IPI, it's already done). Does anybody know, if such a device driver exists. Please reply by E-Mail.

This product supports both concatenation (make two physical disk partitions appear as one aggregate virtual partition) and mirroring (where data is duplicated across two disk partitions to guard against failure). There are also some spiffy graphical tools for examining and manipulating devices and filesystems, along with long-term monitoring. The concat & mirroring work with SCSI, SMD, and IPI drives.
