HP XP128, XP10000 manual

Note 1: The availability of a disk type 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 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 4: The number of blocks for a CVS volume is calculated as follows:

# of blocks = (# of cylinders) × (# of heads) × (# of sectors per track)

Example 1: 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 2: 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 5: 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 = ↑37 × 1024/720↑ = ↑52.62↑ (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 = ↑49 × 16/15↑ = ↑52.26↑ (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
