Businesses will be able to buy storage products that
offerenergy efficient storagewithin six
months.
Speaking to Computer Weekly at the start of the Burton Group
analyst conference in Barcelona, Drew Reeves, research director at
Burton Group, said, "Storage infrastructure used in datacentres
will run more efficient disc drives."
The storage industry body,
SNIA, has been working on a
green storage initiative. Products coming out of this programme
will help businesses to implement tiered storage using low-cost
Serial ATA disc drives as to cache data rather than store data
directly on energy efficient SAS drives.
Reeves said this configuration would enable the datacentre
manager to reduce storage electricity consumption.
"SAS drives consume between five and 10 watts per disc. By using
Serial ATA drives as a cache to store the data first, there is no
need to run the SAS drives continuously. They only need to be
powered when the data stored in the cache has to be written to the
disc," said Reeves.
