[Twg] Cray roadmap priorities

[John Carrier]

The following are Cray's roadmap priorities:

1) larger LUNs   

   Needed for Lustre 1.8.x (both RHEL, SLES) as well as 2.x (RHEL-based
   only).

2) metadata performance  

   General improvements needed for Lustre 1.8.x (RHEL, SLES) as well as
   Lustre 2.x.  Clustered Metadata is an option to improve scalability 
   for Lustre 2.x. 

3) end-to-end data integrity   

   Improve the reliability and resiliency of the file system by
   protecting data from the client to disk.  (Lustre 2.x only)

4) online file system check

   Scrub metadata in the background, capture errors before seen by the
   application, and reduce recovery time when errors are found.
   (Lustre 2.x only)
   
5) interface to HSM              

   Seemlessly move data from Lustre OSTs to archival storage.
   (Lustre 2.x only)

6) channel bonding 

   Provide redundant, active LNET links between routers and servers to
   increase LNET reliability and improve performance between nodes.
   (Lustre 2.x only)
