Emulation Category
CVS LUSE
OPEN-3*n CVS SCSI disk
OPEN-8*n CVS SCSI disk
OPEN-9*n CVS SCSI disk
OPEN-E*n CVS SCSI disk
OPEN-V*n SCSI disk
General notes:
*Capacity = (512 x number of blocks) ÷ 1024
The value n is the number of volumes combined together. For example, with 8 combined volumes:
OPEN-V*8.
1
The availability of an emulation depends on the disk array.
2
The devices are defined to the host as SCSI disk devices, even though the interface is Fibre
Channel.
3
The command device (used for RAID Manager) is distinguished by -CM on the product name (for
example, OPEN-3-CM, OPEN-3-CVS-CM).
4
The device capacity can sometimes be changed by the BIOS or host adapter board. This may
make actual capacity different from that listed in the table.
5
The number of blocks for a CVS volume is calculated as follows:
# of blocks = (# of cylinders) × (# of heads) × (# of sectors per track)
Example
For an OPEN-3 CVS volume with capacity = 37 MB:
# of blocks = (53 cylinders see Note 5) × (15 heads) ×
(96 sectors per track) = 76320
Example
For an OPEN-V CVS volume with capacity = 49 MB:
# of blocks = (53 cylinders see Note 5) × (15 heads) ×
(128 sectors per track) = 101760
6
The number of cylinders for a CVS volume is calculated as follows ( ... means that the value
should be rounded up to the next integer):
OPEN-3/8/9/E: The number of cylinders for a CVS volume = # of cylinders = (capacity (MB)
specified by user) × 1024/720
Example
For an OPEN-3 CVS volume with capacity = 37 MB:
# of cylinders =
(rounded up to next integer) = 53 cylinders
OPEN-V: The number of cylinders for a CVS volume = # of cylinders = (capacity (MB) specified
by user) × 16/15
Example
For an OPEN-V CVS volume with capacity = 49 MB:
# of cylinders =
(rounded up to next integer) = 53 cylinders
OPEN-3/8/9/E: The number of cylinders for a CVS LUSE volume = # of cylinders = (capacity
(MB) specified by user) × 1024/720 × n
