Initially wheneveer I see RAID 1+0 or 0+1, I think it should have at least 4 drives:<br />
2 striped and mirrored to 2 other drives<br />
OR<br />
2 mirrored and striped to 2 other drives.<br />
&nbsp;correct me here if I am wrong.<br />
<br />
<br />
Now I can see in some scenarios(some Servers that have only 2 SCSI Disks) and the array is 0+1.<br />
<br />
can someone explain this?<br />
<br />
<br />
thanks<br />

RAID 0+1/1+0

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
