Available models include: T9840 A, B, C, and D
The T9840 tape drives are
access-centric
tape drives that have an average
access time of just 12 seconds. These tape drives are ideal for applications that
demand high data throughput and fast recall.
The T9840C and D uses a variable rate randomizer, with partial response,
maximum likelihood circuitry and LZ1 as the data recording method.
A 16-channel head reduces the required number of tape passes to record data
to tape and also extends media life (few passes).
These drives obtain their high-performance by using a unique
dual-hub
cartridge
design with midpoint load technology. This design enables fast access and
reduces latency by positioning the read/write head in the middle of the tape.
With the 9840 unique dual-hub design, the entire tape path is contained within
the cartridge, which reduces contamination and enables the drives fast access.
Versions of both enterprise and open system platforms, such as:
Windows: NT, 2000; UNIX: Solaris, HP-UX, AIX; Linux; MVS, VM, and OS/390
Available models include: T9940 A and B
The T9940B use a variable rate randomizer, with partial response, maximum
likelihood circuitry and LZ1—an Adaptive Lossless Data Compression
technique—as the data recording method.
A 16-channel head reduces the required number of tape passes to record data
to tape and also extends media life (few passes).
The tape cartridge for this drive uses a single-reel hub design—the supply reel is
inside the cartridge and the take-up reel is inside the tape drive.
Versions of both enterprise and open system platforms, such as:
Windows: NT, 2000; UNIX: Solaris, HP-UX, AIX; Linux; MVS, VM, and OS/390
