► Tape device IBM device driver overview The IBM Ultrium tape and medium changer device drivers are designed specifically to take advantage of the features provided by the IBM Ultrium tape drives and medium changer devices. The goal is to give applications access to the functions required for basic tape functions (such as, backup and restore) and medium changer operations (such as, cartridge mount and dismount), as well as to the advanced functions needed by full tape management systems. Whenever possible, the driver will take advantage of the device features transparently to the application. 1.6 LVD versus HVD What is it? Why choose one over the other? Why should you care? 1.6.1 What is LVD and HVD? LTO tape drives have two types of SCSI attachment interfaces, LVD (Low Voltage Differential), and HVD (High Voltage Differential). LVD and HVD, as the names imply, use different voltage levels while sending the signal down the SCSI bus. LVD uses 3.3 Volts DC and HVD uses 5 volts DC. LTO tape drives are either LVD or HVD and cannot be upgraded or converted from one to the other. In order to change from LVD to HVD, a LVD drive would need to be replaced with a HVD drive. Therefore, when configuring an LTO product, consider carefully whether you should choose HVD or LVD drives. 1.6.2 Why is this important? Why choose one over the other and why should you care? The most overriding reason is of connectivity. If you to try to plug in an HVD LTO drive into an LVD adapter, it will not work. Placing an LVD device on an HVD bus will cause the LVD device to shut down. Placing an HVD device on an LVD bus will cause the entire LVD bus to shut down. Therefore, check to see what type of adapter you have available in the hosts which will be attaching and choose the correct model of drive accordingly. There are also differences in the speed characteristics of HVD versus LVD. LVD is available either as Ultra2 SCSI which has an 80 MB/s speed or the new Ultra160 SCSI at 160 MB/s, while HVD is Ultra SCSI which has a maximum speed of 40 MBs/sec. Does this mean that the LTO drive will run faster with LVD versus HVD? Not necessarily. The speed seen here is the SCSI bandwidth or bus speed. All Ultrium drives (whether LVD, HVD or native Fibre Channel) have a 26 Using IBM LTO Ultrium with Open Systems
nominal speed of 15 MB/second. If the speed of the bus were the only limiting factor in your configuration, then yes, switching to a faster bus should improve your performance. Usually, the speed capability of the bus will determine the number of LTO drives that can be attached on the same bus. But again, this isn’t the only factor in the equation. In addition to the speed differences, there are connection restrictions associated with each. Both HVD and LVD can span 25 meters in a point to point configuration. In a multidrop (daisy chain) configuration HVD can span 25 meters, while LVD is limited to 12 meters. So which should you choose? If you have a situation where the 12 meter multidrop limitation of LVD isn't an issue, then you would purchase LVD, right? You would think so, but the correct answer is, “it depends”. It depends on the HBA that you have installed in your server. If you have an existing adapter and you don’t want to change it, then whether the adapter is HVD or LVD will dictate which LTO drive you order and the configuration capabilities. What if you don’t already have an adapter. Order LVD, right? Again, not necessarily. At this time, not all supported SCSI HBAs are available in both interface types. For example, AS/400 and SUN support only HVD drives when directly SCSI attached. See the following URL for current information: http://ssddom01.storage.ibm.com/techsup/swtechsup.nsf/support/ultriumcompinfo Table 1-3 HVD and LVD characteristics HVD LVD Point to Point 25 meters 25 meters Multidrop 25 meters 12 meters Speed 40 MB/s 80 or 160 MB/s 1.7 SCSI HD68 and VHDCI cable connectors There are three types of SCSI cables, HD68-HD68, HD68-VHDCI and VHDCI-VHDCI. The HD68 connector is the normal 68 pin SCSI connector. The VHDCI (Very High Density) connector is a mini SCSI connector, about half the width of the HD68 connector. The server SCSI adapter can be either HD68 or VHDCI. For RS/6000, AS/400, and HP servers, LVD SCSI adapters are always VHDCI, and HVD adapters are always HD68. But Sun and Netfinity/NT servers have some adapters that are reversed. The connector type for a given adapter Chapter 1. Introduction to LTO Ultrium with UNIX 27
