For example, with 8 combined volumes: OPEN-V*8. 1The availability of an emulation depends on the disk array. 2The devices are defined to the host as SCSI disk devices, even though the interface is Fibre Channel. 3The command device (used for RAID Manager) is distinguished by -CM on the product name (for example, OPEN-3-CM, OPEN-3-CVS-CM). 4The 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. 5The 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 6The number of cylinders for a CVS volume is calculated as follows ( ... should be rounded up to the next integer): means that the value 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) × 16/15 160 Disk array supported emulations
