I am looking to find out what kind of mb/sec other shops are getting. Our environment
is:
AIX 4.3.3 Server (3466-C00 = H50 2cpu, 1gb mem, 2-gbit ethernet, 1-100mb ethernet)
running TSM 3.7.3.8
3494 library using 3590E drives with 3590K tapes
Switch is Cisco 6509 on a dedicated vlan segment
Client is HP V2200 (16cpu, 12gb mem, 1gbit ethernet dedicated to backup vlan) running
TSM 3.7.2 under HP-UX 11.0
Specifically, when we try to archive a 100gb Oracle database on the HP (as a file
system with approx 450 files, not using EBU/RMAN, residing on an EMC 3700 Symmetrix),
we are seeing aggregate throughput in the 6-7mb/sec range, which translates into
approx 4.5hrs. When we watch the Aix monitor, the gbit interface varies from 15 down
to 1.5mb/sec. The cpu never goes over 20%. The consultant who helped us get this
installed & setup claims that a business down the street with almost identical
hardware/software is able to get a single backup stream to do 80gb/hr. So far we have
involved HP, Tivoli, Aix, Cisco, EMC and almost every techie in our shop without being
able to find a conclusive answer as to where our bottleneck is.
Are other shops seeing anything close to 80gb/hr in a single stream using gb to gb
ethernet connections? Any pointers as to where to look, or recommended tools for at
least diagnosing the problem? Thanks in advance.
