Of the Following Supported Software Which would be the Best Choice for SOFTWARE RAID 0+1 ?

VERITAS Volume Manager software, versions 2.4, 2.5, 2.5.x, and 2.6 Solstice DiskSuite[tm] software version 4.1 Sun Cluster 2.1, 2.2 software

NOTE - Application Leaning MORE of OLTP in nature though some amount of Batch processing also happens

Thanks indeed

Vivek,

Depending upon the usage of database I may take decision. Also what software are ou going to use for the raid. Veritas is good in stripping data upto a good granualarity.

For a one application database I would think of optio n 1 or 2 with software like veritas with a strioung of 128K in OLTP. But for data warehous I would have RAID 1 (mirror ) and 6 volumes to strip my data manually.

Given SUN D1000 Storage Box Containing 12 Disks , For Database Layout what would be the most optimal Setup ?
1) 1 Volume Software RAID 1+0 Containing 6+6 Disks ? 2) 2 Volumes - Each Volume consisting of Software RAID 1+0 Containing 3+3 Disks
3) 3 Volumes - Each Volume consisting of Software RAID 1+0 Containing 2+2 Disks
4) Any Other Combination

NOTE D1000 Storage Box :-
1) Does NOT have a Hardware RAID Controller 2) Contains HIGH PERFORMANCE JBOD ARRAY
Feature: High Performance JBOD Array (D1000). Function: The D1000 has 2 UltraSCSI channels, with 4 UltraSCSI connections. The Netra st D1000 can be configured with dual 40-MB/second UltraSCSI Channels.
Benefit: The servers may access the disk drives as individual storage components or may use software RAID solutions to aggregate the disk drives into bigger logical disk volumes.
