Is this normal for sleep training?

I've seen a few other posts about sleep training and I'm wondering if this is normal for the first night. We did the Ferber method and baby took about an hour to fall asleep. Once asleep he only slept about 30 minutes and then we would have to repeat the check ins until he back to sleep.

The longest stretch he went was about 3 hours once and then he slept for 2 hours once.

All together he only had about 6.5-7 hours total of sleep. We put him down at 7 and got him up at 6.
