MSDP Configuration Tuning on NBU5230

Hello,

I deployed an NBU5230 version 2.6.0.4 as an MSDP media server. We have performance issue with tape out from the appliance MSDP so I do a little research on the internet. I found that there are some settings we can tune on the contentrouter.cfg and pd.conf file.

My question is there are more than one location of those configuration files, which file should I edit?

e.g.

/usr/openv/pdde/pdcr/etc/contentrouter.cfg

/disk/etc/puredisk/contentrouter.cfg

 

Thanks & regards,

Chan KH.

    Seems like a lot of tape drives for one appliance.

    How did you arrive at, or deduce that, one appliance is capable of concurrently driving/utilising seven LTO6 tape drives?

    Did you scope / size / scale / capacity plan / design / confirm capability... for seven tape drives?

    Or did someone else unilaterally decide that seven tape drives would be ok?

    I gave you the wrong file to use. Use the one in /disk. If you do an ls -l on both file you will see one is read only where the other is read write for root.

    As for the values being different what are they?

    Edit the one in /usr/openv. The other is a memory copy similar to what you find in /proc at times.

    How many tape drives are you duplicating to concurrently?  And what models (LTO? 4/5/6?)

    Thanks Andrew. However, I notice both files have different values set. Doesn't the memory copy duplicate from the /usr/openv... settings?

    We are con-currently duplicating to 7 tape drives - HP Ultrium 6 (LTO6).

    Is the one appliance attempting to duplicate to seven LTO6 tape drives?

    Or are the seven tape drives shared in an SSO environment across more than one media (or master/media) server?

    One appliance duplicating to seven LTO6. It is in an SSO environment but other media servers do not use the drives unless during adhoc cases.
