[Lustre-discuss] Multiple IB ports

[Brian O'Connor]

Hi,

    Any body actually using multiple IB ports on a client for an
aggregated connection?

 

Ie. Many oss with one qdr IB each. Clients with 4 qdr IB ports. Assuming
the normal

issues with bus bandwidth etc, what sort of perf can I expect 

 

qdr ~ 3-4Gbytes/Sec

 

I'm trying to size a cluster and clients to get ~10GBytes/Sec on *one* 

client node. 

 

If I can aggregate IB linearly the next step will be to try and figure
out

How to get 10Gigabytes/s to local storage :-(

 

 

Some times customers are crazy.......
