[Twg] Cray priorities list

[John Carrier]

Andreas requested that Cray order our list in priority order.  

1. Avoid RPC timeouts
2. File create performance
3. HSM and storage management infrastructure 
4. Single client performance 
5. Scalable fault management 
6. Improved LNET robustness 
7. OST migration/rebalancing 
8. LNET channel bonding 
9. Asynchronous file replication (mirroring) 
10. Improved Lustre tests

This new order is reflected in the new spreadsheet update.  The change does not qualitatively change our recommendations to the board.  

Thanks,

--jc

John, the other lists were provided in priority order, and the spreadsheet is using this to select top-ranked aggregate features.  Could you please add these to the spreadsheet in ranked order, or alternately I guess you could use "5" as the rank for all items.

Cheers, Andreas
