Mode 2 will do the job the best way for you in case of static LAG supported only at the switch's side, I'd advise using of xmit_hash_policy layer3+4, so you'll get better distribution for your DC. 


Thanks in advance. 

Best regards, 
Nikolai

This switch is more of an office switch and only supports part of the 
802.3ad standard: 


PowerConnect* *2824 

Scalable from small workgroups to dense access solutions, the 2824 
offers 24-port flexibility plus two combo small?form?factor 
pluggable (SFP) ports for connecting the switch to other networking 
equipment located beyond the 100 m distance limitations of copper 
cabling. 

Industry-standard link aggregation adhering to IEEE 802.3ad 
standards (static support only, LACP not supported) 


So the only way to have some kind of bonding without buying more 
expensive switches, is using balance-rr (mode=0), balance-xor (mode=2) 
or broadcast (modes=3).

Sorry, no mode 0. So only mode 2 or 3 for your environment....
