Implications of Using Multiple LVs in iSCSI Failover Configuration

You'll certainly want to go with 10GBE. Don't try using multiple nics. Its just not a very scalable method IMO

Thanks -- I'll wait to drive a Ferrari too .... Just kidding.

I agree with your assessment but the information I'm trying to get at is whether or not bonded NICs will increase performance at all in the case of multi-LV replication.

Basically -- is it one job that does replication (ie, one TCP stream) or multiple jobs (ie, N TCP streams). If multiple, then we can take advantage of multiple NICs even if that's not an ideal solution. If one, then you're right that 10GbE is the only option...

Thanks again

Each replication job is independent of the other, so yes, it is multiple streams.
A dedicated 10GBE link between two DSS servers is so affordable nowadays, I can finally start recommending it. A CX4 10GB adapter will probably cost a wee bit more than say a 4 Port Copper Nic. Many Supermicro mobos have 10GBE built onto the platform. It's better for overall cable management, IRQ management and performance.
