Access "The rise of the ultra-dense array"

Published: 20 Oct 2012

The rise of the ultra-dense array Higher disk densities and smaller form factors will affect power and performance. EVEN IF BUSINESS demands haven't driven you to classify data and implement tiered storage, changes in technology and relentless data growth will force you to consider these initiatives. Ever-higher data density on disk platters will slow performance, just as applications demand more. To maintain performance, we'll soon have ultra-dense arrays with massive numbers of tiny drive mechanisms that guzzle power and spew heat. It will end only when we get real about data requirements and force the bulk of our storage onto big, slow, efficient drives. Tiered storage is coming whether we like it or not. Packing more into less Data is growing at an alarming rate. It's certainly compounding, and some recent studies suggest the growth rate is accelerating. So far, disk capacities have kept up with the growth of space usage, even outpacing Moore's Law. In a past column (see "Five axioms for storage," Storage, June 2004), I noted that while disk capacity ... Access >>>

    • Time to think outside the box when it comes to data protection

      Storage Bin: The concept of "That's the way we've always done it" isn't going to work anymore, and it sure won't help you build an efficient disaster recovery plan. It's time to think outside the box when it comes to data protection.

    • The rise of the ultra-dense array by Stephen Foskett

      Disk drives are getting smaller and smaller even as their capacities rise. Now storage vendors are packing more disks than ever into smaller spaces, which saves costly data center real estate. But the denser arrays also have a downside--higher power consumption and more heat.

    • A look at data classification products for e-discovery

      New technology products that look inside data can help you classify and manage that data more effectively. But these tools can also be leveraged for e-discovery, allowing specific data to be found and acted upon quickly to satisfy legal requirements.
