The drive can be integrated into a system (internal model) or can be provided as a separately packaged desktop unit (external model). The Dell PowerVault 110T LTO-3 tape drive (called Generation 3) is the third-generation tape drive in the LTO series of products. The Dell PowerVault 110 LTO-3 tape drive offers a formatted cartridge capacity of up to 400 GB (800 GB assuming 2:1 compression ratio) and a data transfer rate of 80 MB per second (135 MB per second at maximum compression). Figure 1 shows a front view of the internal model of the tape drive. Figure 2 shows a front view of the separately purchased external model of the tape drive. Figure 1. Front View (Internal Model) Figure 2. Front View (External Model) SCSI Bus Interface These tape drives are designed to operate on an Ultra160 low voltage differential (LVD) SCSI bus with a burst transfer rate of 160 MB per second. The interface is backward compatible with older SCSI technology. The tape drive contains a high-density, 68-pin, D-Shell (HD-68) connector for attachment to the system. The drive supports LVD SCSI cables with HD-68 connectors. Features The tape drive has the following features: l Capacity of 400 GB (native), 800 GB (compressed*) on a single LTO tape l Built-in read-after-write verification for a high level of data integrity l Data transfer rate of 80 MB per second (native), 135 MB per second (compressed*) l 128 MB of read/write cache memory l Intelligent LTO-DC dual-mode compression algorithm l Failsafe leader capture mechanism with pin pick error recovery l LTO-Cartridge memory l TapeAlert support for worry-free backup l Ultra160 LVD SCSI interface l Speed matching (The tape drive can slow down to match the system data rate.)
