ULTRA2 LVD SCSI HOST ADAPTER

4.4.1WHY YOU NEED TO DO THIS

A new SCSI disk drive is normally low-level formatted at the factory to simplify installation. Every SCSI hard-disk drive must be physically low-level formatted, partitioned, and logically formatted before it can be used to store data. SCSI hard disks are physically low-level formatted at the factory and do not usually need to be formatted again. (If you do need to low-level format a disk, see Section 4.4.2.)

Howevere, if you connect a new SCSI hard-disk drive to your Ultra2 LVD SCSI Host Adapter, you must partition and logically format the drive. For DOS, Windows 3.x***?, Windows 95, and Windows 98, use the DOS commands FDISK and FORMAT to do this (refer to the documentation for your PC, your hard drive, DOS, and—if necessary—Windows). For other operating systems, refer to the operating system’s documentation for instructions.

If you are booting from a SCSI hard-disk drive, make sure the “Hard Disk” or “Hard Drives” setting in your PC’s CMOS program is set to “None” or “No Drives Installed,” as is required for SCSI hard drives. See your PC’s documentation for details.

If you’ve installed both SCSI and non-SCSI (IDE, for example) disk drives, the non-SCSI drive is typically the boot drive. But if your computer supports the BBS (BIOS Boot Specification), not only can both SCSI and non-SCSI drives coexist, you can specify which drive to boot from. See your PC’s documentation for more details.

4.4.2LOW-LEVEL FORMATTING

A low-level format will erase any data that is stored on the target disk. Before attempting to perform a low-level format, make sure the data on the target disk has been backed up. You can do a low-level format with the Ultra2 LVD SCSI Host Adapter’s SmartSCSI Setup Utility; see Section 4.6.6.

The low-level format sets the media to a state which is easily recognized by the host adapter on the SCSI bus. Once this format is completed, you will need to partition the drive. Refer to your operating system’s documentation for further information on partitioning drives.

SCSI-2 LVD specifications

The Black Box SCSI-2 LVD (Low Voltage Differential) represents a significant advancement in data storage and connectivity technology, particularly in environments requiring high performance and reliability. As a variant of the SCSI (Small Computer System Interface) standard, it is optimized for faster data communication, essential for modern computing needs.

One of the main features of SCSI-2 LVD is its capability to handle increased data transfer speeds compared to its predecessors. It supports a maximum data transfer rate of up to 80 MB/s, which is double that of the original SCSI-2 single-ended signaling. This increase in speed is largely due to the differential signaling that LVD employs, allowing for reduced electromagnetic interference and extended cable lengths while maintaining signal integrity. The technology effectively converts the SCSI bus into a more robust system that can accommodate various devices without compromising performance.

The SCSI-2 LVD standard is backward compatible, meaning that it can interface with older SCSI devices, albeit at reduced speeds. This compatibility is significant for users looking to upgrade their systems without discarding existing hardware. This makes SCSI-2 LVD an attractive choice for enterprise environments where legacy systems are common.

Another key characteristic is the flexible cabling options provided by SCSI-2 LVD. It can support cable lengths of up to 12 meters, which is beneficial for large data center configurations where space between devices can be substantial. This extended range does not typically come at the expense of performance, ensuring that data integrity remains high, even over longer distances.

In terms of technology, LVD employs lower voltage levels, which not only contributes to greater power efficiency but also minimizes heat generation in devices. This is particularly crucial in data centers where temperature management can impact hardware longevity and reliability. The combination of lower voltage use and differential signaling makes SCSI-2 LVD well-suited for high-density environments.

Error correction and handshaking features are also integral to SCSI-2 LVD, enhancing its robustness against data loss during transmission. These characteristics make it a reliable choice for applications requiring consistent and high-speed data access, such as server arrays and high-performance computing tasks.

Overall, Black Box SCSI-2 LVD stands out due to its impressive speed, compatibility, and extensive cabling options, positioning it as a reliable solution for demanding data environments. It effectively bridges the gap between legacy systems and modern technology, ensuring that users can optimize their data handling capabilities without significant disruption.
