Plugging the Gap in Green IT

There's more to saving power than 'spin-down' disks and flash memory

From flash memory to low-power SATA drives and spin-down disk technology, green storage has certainly been one of the big themes of EMC World this week.

EMC finally unveiled its first system containing spin-down disk technology yesterday, and also talked up the energy saving benefits of flash and low-power SATA drives.

Not to be outdone, EMCs arch-rival HDS timed a major green announcement of its own to coincide with the first day of EMC World.

By announcing support for flash drives and availability of 1-Tbyte SATA drives in its USP V and USP VM, HDS clearly wants to be seen banging the same eco-friendly drum as EMC.

At least one analyst thinks that these technologies, although offering some energy savings, are just one small part of the broader green equation.
