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... (4 Replies)
hai everybody n good morning........here r some queries.......
1. what is the interlace value in RAID 0 (striping.......)

when I type lspv ; I used to see 3 physical disks ( two local disks and one raid 5 disk )
suddenly the raid 5 disk array disappeared ; so the hardware engineer thought the problem was with SCSI... (0 Replies)

ataraid
ATARAID(4) BSD Kernel Interfaces Manual ATARAID(4)NAME
ataraid -- software BIOS RAID
SYNOPSIS
pseudo-device ataraid
ld* at ataraid? vendtype ? unit ?
DESCRIPTION
The ataraid driver provides support for BIOS-based software RAID controllers. These are devices which have some simple support for several
basic RAID levels (often RAID 0 and RAID 1), but which require software support to actually perform the RAID function. The BIOS support is
largely just to create and recognize the array so that it may be a boot device.
The driver currently supports RAID formats from:
o Adaptec HostRAID (found in Intel 6300ESB)
o Intel MatrixRAID
o JMicron RAID
o nVidia MediaShield
o Promise FastTrak
o Via V-RAID (found in many VIA-based motherboards)
Status of the logical disk as well as the disks associated with it, can be viewed through the bioctl(8) utility.
SEE ALSO ld(4), bioctl(8)HISTORY
The ataraid driver first appeared in NetBSD 2.0.
AUTHORS
The ataraid driver was originally adapted from FreeBSD by Jason Thorpe <thorpej@NetBSD.org>.
BUGS
Not all features of the software RAID are currently recognized or supported. For example, the Adaptec support doesn't recognize when a RAID
1 should be in a ``building'' state, and it does not do the right thing.
At least part of the reason for this is that the publically-available information on these formats is quite limited.
