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,
