Last week's announcement that yet another vendor has made adaptations to its deduplicating system to support archive retention as a new system feature can mislead companies into drawing the conclusion that if this appliance works for backup that it is suitable for archiving as well. Many companies are frugal when it comes to storage purchases so if they can buy a disk-based appliance that addresses both their archiving and backup needs, they may be tempted to do so. (read more)

One would think that at some point organizations would reach the tipping point for storage consumption and that year-over-year storage capacity growth rates of 30%, 50%, 100% or more would come to an end, or at least slow down. If so, it hasn't occurred yet and, if anything, it shows every sign of continuing for the foreseeable future. Nowhere is this more evident than with the amount of data that companies need to archive and retain. (read more)

The Computerworld column I wrote a few weeks ago on the topic of "A Bit of a Flaw with SATA disk drives" sparked quite a bit of debate around just how safe is data on today's RAID-based storage systems that use SATA disk drives? A series of comments appeared on Computerworld's site where the column appeared as well as on a forum at Nabble's web site. Also, at least one storage system vendor felt obligated to send me their white paper that explains how its RAID-based storage system accounts for this bit error rate problem on SATA disk drives.

It's 2008 and one would think that disk-based storage systems are beyond the point of catastrophic outages and/or data loss as a result of disk drive failures. The prevalent use of RAID in storage systems for disk drive protection in its many forms would seem like ample insurance against the loss of data. However a careful examination of the facts exposes the flaws in assuming that RAID alone is sufficient as a means of data protection; especially when used in conjunction with today's high capacity SATA disk drives.

However as companies move towards archiving data on disk-based storage systems, you can't just always build bigger buildings or knock down walls. If anything, companies want to store more data in a smaller footprint. Making it more complicated, companies are creating exponentially more data than they were 10, 5 and even 2 years ago and keeping it for longer periods of time. Factor in mobile devices that manipulate existing data and create new data and the increasing use of video in corporations and the result is millions, billions and even trillions of file-based data elements that create thousands of terabytes of data.

One can hardly have a conversation about storage management these days without the topic of archiving surfacing. Part of the reason that archiving is commanding more attention is because as companies create and keep ever greater amounts of referential data on their production storage systems, it is creating a host of new problems (read more)
