The value n is the number of volumes combined together. For example, with 8 combined volumes:

OPEN-V*8.

Note 1:

The availability of an emulation depends on the disk array.

Note 2:

The devices are defined to the host as SCSI disk devices, even though the interface is Fibre Channel.

Note 3:

The command device (used for XP Raid Manager) is distinguished by -CM on the product name (for

example, OPEN-3-CM, OPEN-3-CVS-CM).

Note 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.

Note 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

Note 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

37 × 1024/720

49 × 16/15
