Having problems with your HP ProLiant DL380 G4 Server ?

I have hp proliant with raid 1+0 .I have 2 hard and usr in option

\015 I have 2 hard and must be not can raid 1+0 (because raid 1+0) need 4 hard.but in hp I can raid (1+0) them .do it works same of raid1?\015

Answers :

No ,RAID 0+1 need minimum 2 disk because 1 disk is the mirror of the second disk ,consequently,the number of the disk for RAID 0+1 must be even.Raid 0+1 is the same as the Raid 1 (mirroring) .but it is faster than Raid 1 .because raid 0 has stripping .
Sometimes shortened to RAID 10, RAID 1+0 is a particular combination of\015\012two different RAID levels: mirroring (RAID 1) and striping (RAID 0).\015\012The appeal of RAID 1+0 is simple: mirroring gives you the highest level\015\012of availability RAID offers, with the fastest rebuild times when a disk\015\012fails; while striping - using the proper chunk size - is the basis for high-performance I/O.
