Currently my average dump rate on a 100mbit full switched network
consisting of Cisco 2948G's and Dell Pentium III 800 mhz with 512 megs of
ram server is at:
Avg Dump Rate (k/s) 364.5 364.5 --
How can I speed this up?
In amanda.conf I have set netusage to 50000 kbits.
should I increase that number, decrease the number of dumps running
concurrently, shouldn't my network card be able to handle at least 4
megabytes per second, (3com 35905B 100mbit)? Does high compression play a
factor in the file transfer, or does the compression be done on the client
machine then sent over the network to the dump disk?
My hard disk also is set up as this:
define interface local {
comment "a local disk"
use 50000 kbps
}
My local disk is an IBM Ultra 2 9 gig 10000 RPM drive. I believe 50000
kbps is sort of slow for a drive like this, but I don't get any
improvements by bumping this number up?
What can I do to increase my dump rate? Also does amanda ignore, when
defining a tape type the speed of what the tape drive is capable? Does it
leave determining the speed to the actual drive and interface?
define tapetype M2-AME225 {
comment "Exabyte EZ17 Mammoth2"
length 57487 mbytes
filemark 0 kbytes
speed 11765 kbytes
}
Avg Tp Write Rate (k/s) 6689.9 6689.9 --
Im assuming that compression may play a role in the speed of the tape
drive copying content?
Any suggestions are greatly appreciated,
Thank you,
