You need a Heroics<-->Karazhan Geared 30-40 man raid to down him. That means everyone in the raid must have a little bit of kara experience/gear.
TANKING
Your Main Tank, raid buffed, needs to have at least 15k health and armor with 18% dodge & parry and 25% block. He will get hit for 8k, but the attacks are slow and successful blows are infrequent. Keep him topped off.
I recommend having an equally geared druid tank standing by to pick up agro with a charge and taunt should the MT lose threat.
HEALING
You NEED two or three resto druids keeping the entire raid topped off.
You NEED two or three Holy Paly's in the raid.
You NEED at least one Holy Priest and one Holy Paly keeping the Tank/s and Melee DPS alive.
The raid should have three shadow priests. One for the Resto Druids, one for the Tank's healers, and one for the highest DPS group using mana.
You should NOT have more than 7-8 healers in the raid. 2 Resto Druids, 3 Paladins, and 1 or 2 Priests is the way to go.
DPS
If at all possible have as much ranged DPS as you can. He has an insane chain cleave that increases damage with the number of players it hits. Having your melee DPS directly behind him helps.
After a minute he enrages, sending out 6 Shadow Bolt Volleys in a row. EVERYONE but the Palys and tank/s need to run like hell for the duration. Palys bubble and spam heal tank/s.
If someone in the raid dies, Kazzak gains about 8% of his health back instantly.
If you can set up a raid like this you can down this guy. He is easier than Mag, especially if you do it right.
Good Luck and Have Fun!
