Answer / srinivasa rao

raid is knothing but a redundent array of inexpensive
disks this can be used in solaris for redundency of data
and availability mostly used raid configuration are
raid0,raid1 and raid5 where as volume manager used for same
thing above mentioned but we can increase the slice size in
online and also decrese the slice also.

Answer / s ramesh reddy

Raid stands for Redundent Array of inexpensive Disk OR Redundent Array of Independent Disk. It is having different levels i.e., Raid0, Raid1, Raid 0+1, Raid 1+0, Raid 5. We have increase the span of file system across the Hard Disk and Protect the data of file system. But with in the Hard Disk only 7 Slices only.In Raid Levels Raid 1+0 is not support to the SVM.

In Volume Manager have Raid & LVM (Logical Volume Manager). Raid is growths the file system but in LVM there is no limit for 7 Slices , here creating N number of slices as for the file size.

Answer / sreejith

In solaris, using RAID you can create maximum of 8 slices,
Volume manager helps you to create as many partitions as you
want using soft partitions.

Answer / sivakumar

Dear Fried,

If we see aerial way we can not identify any difference
inbetween RAID and Volume Manager. Whereas we see ground
level it seems difference. We can see those things below:-

RAID: It is an aronym for Redundant Array of Inexpensive
(or Independent) Disks. There are 6 RAID levels are
existing, which are 0-5. In solaris we are using raid-0,
raid-1, raid-5. Very few storage environemnts support RAID
levels 2,3 and 4.

VOLUME MANAGER: Which you control the devices to store the
data in expected disk. We can get back those data without
loss. For that we are using various storage methods is
called RAID LEVEL.
