I'm waiting for my RAID-5 to be migrated from 64 to 256k as recommended, now in the meatime I added channel-bonding (802-3ad):
- Two-port Intel Pro1000 MT Server Adapter
- Cisco Cat3750G config on both If to DSS: " channel-group 2 mode active"
Code:
s04602#sh lacp int
Flags:  S - Device is requesting Slow LACPDUs
        F - Device is requesting Fast LACPDUs
        A - Device is in Active mode       P - Device is in Passive mode

Channel group 2
                            LACP port     Admin     Oper    Port     Port
Port      Flags   State     Priority      Key       Key     Number   State
Gi1/0/18  SA      bndl      32768         0x2       0x2     0x12     0x3D
Gi1/0/19  SA      bndl      32768         0x2       0x2     0x13     0x3D
So it seem to run LACP..

But Traffic is going only over the second Interface (eth1 & Gig1/0/19) from the DSS, at least for one connection.. I either misunderstood lacp or something is wrong. At least this bonding won't help anything to improve iSCSI-performance..
