StorageTekT 9840 tape drive
The StorageTekT 9840 "access-centric"
tape drive offers superior speed and unmatched data access, along
with excellent capacity, for transaction-intensive, time critical
applications. With its unrestricted connectivityTopen systems to
mainframe, Ultra SCSI, ESCON and native Fibre Channel (ideal for
SAN attachment) the 9840 is engineered for fast-paced businesses
that need to maintain continuous and economical on-demand access
to a wide range of data.
- Reduce the time needed to perform NearlineT
searches, inquiries and restores; mid-point load, a mere 8 second
average search time, and a native data-rate of 10 megabytes per
second combine to provide rapid answers to data searches.
- Back-up more data in less time. Each cartridge
stores 20 gigabyte native capacity and 40 to 80 gigabytes or more
with data compression (a standard feature) for fewer loads and
unloads, making the 9840 an ideal back-up device.
- With automation and AMT (Adaptive Media Technology)
you can combine 9840 with virtual and capacity tape offerings
to precisely address your customers' needs with your own business
objectives.

A 9840 access-centric tape drive allows you to
store and share information reliably and quickly. Because the 9840
works seamlessly with most StorageTek tape libraries, you can enhance
the value of your investment in automation while managing the conundrum
of today's business - managing massive and growing amounts of data
while keeping it accessible to all...without breaking the bank.

Individual compression achieved is a function of many
variables, including the data characteristics. For example,
scientific data usually compresses less than general
business data. As a practical guide, mainframe (MVS/ESCON)
compression rates are typically 4:1, while client server
operating systems (UNIX/NT on SCSI or Fibre) usually
achieve in the 2:1 to 2.5:1 range. In all instances,
slightly lower or significantly higher numbers may be
achieved.
