[gpfsug-discuss] BM Spectrum Scale transparent cloud tiering

[Marc A Kaplan]

Since this official IBM website (pre)announces transparent cloud tiering 
...
http://www.ibm.com/developerworks/servicemanagement/tc/gpfs/evaluate.html?ce=sm6024&cmp=IBMSocial&ct=M16402YW&cm=h&IIO=BSYS&csr=blog&cr=casyst&ccy=us&s_tact=M16402YW


And since Oesterlin mentioned Cluster Export Service (CES), please allow 
me to (hopefully!) clarify:

Transparent Cloud Tiering uses some new interfaces and functions within 
Spectrum Scale, it is not "just a rehash" of the long existing DMAPI HSM 
support.
Transparent Cloud Tiering allows one to dynamically migrate Spectrum Scale 
files to and from foreign file and/or object stores. 

on the other hand ...

Cluster Export Service, allows one to access Spectrum Scale files with 
foreign protocols, such as NFS, SMB, and Object(OpenStack)

I suppose one could deploy both, using Spectrum Scale with Cluster Export 
Service for local, fast, immediate access to "hot" file and objects 
and some foreign object service, such as Amazon S3 or Cleversafe for long 
term "cold" storage.

Oh, and just to add to the mix, in case you haven't heard yet, Cleversafe 
is a fairly recent IBM acquisition,
