Is there any mature open source alternatives out there? How are
other organisations dealing with transparently presenting different
tiers of storage to non technical scientists?
Just curious -- how large and how big are the deltas in the
hierarchy?
I ask because the new generation of 2TB SATA disks appear to be
establishing the groundwork for a list of new storage options
including cluster file systems that run circles around NFS and large
storage RAIDS.
HFS's and tiering in general make sense when the cost of the high
performance storage per GB or per TB is so large as to make it
impractical to keep all of the data on disk.
As Tom points out, this really isn't the case anymore. Petabytes of
very high speed, very reliable storage can be had for far less money
than in the past.
This doesn't mean that HFSes don't make sense for some cases. Though
those cases are diminishing in number over time.
