Product Specifications
Physical Dimensions
Table 1 provides physical dimensions for the tape system.
Table 1. Physical Dimensions
Storage Capacity
The following provides native and compressed capacity ranges for the Super DLTtape I cartridge:
l
Native Storage Capacity = 160 GB
l
Compressed Storage Capacity = 320 GB (2:1 compression ratio)
In accordance with industry practice, a typical compression ratio of 2:1 is quoted. Actual compression ratios achieved depend on the redundancy of data files being recorded.
Data Integrity
SDLT data transfer errors are extremely rare; the following table shows the data integrity for the overall tape system.
Table 2. Data Transfer Error Rates
Reliability (MTBF)
Mean time between failures (MTBF) for the tape system is 250,000 hours. Head life is a minimum of 30,000 tape motion hours, and an average of 50,000 tape motion hours.
Media durability is 1,000,000 passes over any single part of the tape.
Note that this specification does not warrant that predicted MTBF is representative of any particular unit installed for customer use. Actual figures vary from unit to unit.
Load and Unload Cycles
Load and unload cycles are rated at 15,000 for the cartridge itself. The following table shows the number of load and unload cycles and tape insertions the drive itself can
perform before it needs to be replaced.
NOTE: These specifications are provided by the manufacturer for information purposes only and do not constitute an extension of Dell's warranty to you. Dell's
warranty is contained in the documentation for your system.
