To be honest, I've been too chicken to bring the one harc down to test it. I have it in a remote pop, and it hasn't crashed since I set it up. But I've been given no reason to suspect that it doesn't work. What have you experienced? Have there been other bad experiences with this feature? das System Administrator (sysadmin@nebi.com) spake:
Das,
How did you get dynamic assignment to work? Is it reliable after a certain version of code? When I tried it, I pulled all my hair out; finally I decided I could telnet in and manually switch ownership to get it to work and save time in the long run....

Too true. I just had a chassis die over the weekend with one HARC running 10 DSP cards. Needless to say, the customers were nonplussed. I ordered a backup HARC the next day. The other thing nice about running two HARCs in one chassis is being able to do load balancing and dynamic assignment. (Takeover if one HARC fails)

I think the reasoning on adding a second harc isn't due so much to performance as it is to reliablility. Imagine the customer feedback if you had 8 T1's not running right due to a hardware failure on a single HiperArc. Two weeks after I got my second HiperArc, the first one died - needless to say I was glad for that second one...

I have a TC chassis currently running seven channelized T1s. I have read the maximum for 1 HARC is 10 DSP. Now, in the past we have tried running 10+ DSP cards with 1 HARC and the chassis did not perform as well as a chassis that not fully loaded. (This is from records, I wasn't actually working with the TC when this happened). Is there any issues I should know about before trying to run a TC chassis with 8+ DSP cards?
