goes through the roof. Within
this data, astronomers may find
answers to some fundamental
questions about the universe, but
this won't be possible if the system is too expensive to operate.
Some parts of the data collected are more valuable than
others. This got our IBM Research
team thinking about how our
brains work. We collect a lot of
information every day with our
eyes, ears and so on, but we don't
remember everything. We remember only what seems important or
relevant, and forget things that
aren't. Our brain automatically
does this classification.
We thought, "Why not apply
these principles in a large-scale
data storage system? Why not,
as data comes into the system,
analyze it, decide whether it's
likely important and then choose
what type of medium to store it
on-whether it's flash, hard drives
or tape-and the type of redundancies involved, such as how
many backups you need?" Then,
the system performance and reliability are optimized to take into
account data values.
ISM: How does this differ from
current storage systems?
Giovanni Cherubini (GC):
Current systems already do some
of this optimization, with respect
to data popularity; they keep track
of how frequently each file or piece
of data is accessed. They might
move frequently accessed data-
hot data-to faster devices such as
flash, or they might move data to
other storage media as it becomes
colder. We're looking at adding
this new notion of data value
because, although some correlation might exist between the value
and popularity of the same piece
of data, not all data that's popular
is valuable and vice versa.
Therefore, we can add what
we call the computing/analytics

units and selector, which includes
a learning system that can be used
to teach the system what's important and what's not.
For example, if a user is presented a sample of the files he

owns, he can say, "These files are
important. These files are not so
important." Then the learning
system looks at the file content
and metadata to see whether
patterns exist between the file
