Hello everyone,
Just a question about how to increase tape data copy speed. We are getting
a tape copy speed of 15 gb/hr
on stk-9840 drives with stk-9710 library. The tapes can run at a speed of
10 MB/sec which count to 36 GB/hr. We once when adsm-db is small, got a
speed of tape copy in 23 minutes (20 gb). But now invariably
we are getting a speed of 20gb in 1hr 20 minutes (fastest), that counts
to about 15 gb/hr. (like move data,
or migration or backup stg copies).
I appreciate, if any body can give a clue whether the tape can be made to
copy faster, upto its speed; which
adsm-tsm 3.7 or aix-4.3 parameters can help to speed them up. We have 8
drives with 4 scsi-cards, each
with daisy chaining 2 drives / card-cable; within one library.
Thanks in advance, vijay.
