Read and write requests are sent to the RAID controller and must be translated into one or more read or write requests to individual disks.
Read and write requests are sent to the RAID controller and must be translated into one or more read or write requests to individual disks. Each individual request is targeted to a single disk and specifies a starting LBA and a length in sectors to identify a contiguous sequence of or more sectors Given the following operations on the RAID volume, translate them to the corresponding read or write operations, giving type read or write disk number, LBA, and length for each operation.
A writeLBA count
B readLBA count
Your answer should give a sequence of disk operations, with values specified per operation:
read or write
disk number through
starting disk LBA for operation
length of operation in sectors
The following diagram shows a disk RAID array, again with a stripe size of sectors Sectors in the RAID volume and on individual disks are indicated as above.
Given the following operations on the RAID volume, translate them to the corresponding read or write operations, giving type read or write disk number, LBA, and length for each operation. There are several ways in which B and C may be performed; for each give the one resulting in the fewest resulting read and write operations.
A readLBA length
B writeLBA length
C writeLBA length
Again, please specify an exact sequence of disk read and write operations. Note that this question has multiple correct answers, each of which can be expressed multiple ways.
