  NEW!  Storage systems and virtualisation - your fate is to disaggregate (05 Sept 2006)
The value of a storage system is in its software and controller architecture. The most important thing to customers is that the storage is reliable, so their data is well-protected and accessible when needed. Performance is also important, since the user experience and/or application needs to be efficient and productive. If not, operations, productivity and revenue can all be adversely impacted. Data replication is essential in the event of data corruption, accidental deletions or major disasters. Increasingly, being able to move data between different tiers of storage is becoming critical in order to improve IT efficiencies. And yet, there are many customers who buy as well as many vendors who sell storage based on the cost per GB. While there are some vendors trying to position their value based on their software and not disk capacity, this is more the exception and not the rule.

  Clustered storage will win (26 June 2006)
Most storage systems today support some level of clustering. Leading storage system vendors support dual-controller node configurations with active-active or active-passive architectures. However, storage systems that support N-way active architectures scale well beyond dual-node systems. In addition, storage systems with no theoretical limit to how large they can scale have been implemented with 80 or more controller nodes in a single cluster.

  D2D2D -- Disaster recovery for the rest of your data (08 May 2006)
Its no surprise that disk-to-disk (D2D) backup is being embraced by companies of all sizes. The most common method is using a storage system, either NAS or SAN, and setting up a policy for your backup application to back up to a disk target. A large number of companies have leveraged their existing storage systems using ATA/SATA drives to perform D2D backup. Additionally, appliances that are specifically designed for D2D backup are available from various vendors (e.g., Data Domain, Exagrid and NetApp). More on disaster recovery>>

  VTLs: What's the big deal? (27 March 2006)
Nearly every leading storage vendor now has a virtual tape library product, and nearly every customer I talk to is interested in VTL or has already implemented it. Okay, so a VTL system emulates a tape library… but what else does it do?

  iSCSI vs. FC performance: A closer look (26 Jan 2006)
Think that FC is faster than iSCSI? Vice versa? Storage expert Tony Asaro explains why the real answer may surprise you.

  Storage: Getting closer to cake (19 Dec 2005)
The storage system landscape is diverse, competitive and rapidly growing. While the fundamentals haven't changed, the technology is constantly moving forward. There are pockets of innovation that are game-changing, and we are on the edge of making great leaps forward.

  An introduction to thin provisioning (17 Oct 2005)
One of the more important but often misunderstood advancements within data storage is thin provisioning. This article defines and discusses thin provisioning, its economic impact and how it works.

  Approaching storage-virtualisation products (16 Sept 2005)
You know you want to implement some sort of storage virtualisation, but where do you start? Tony Asaro lays out a number of different approaches to storage virtualisation that will help you choose which product or products are best for you.

  Storage virtualisation -- V is for victory (15 Aug 2005)
Virtualisation gives you the ability to utilise the total capacity of all of your storage systems despite their locations or dedication specifications. Read why Tony Asaro says that moving away from discrete storage...

  The athlete vs. the geek: Block vs. file storage (08 July 2005)
Having difficulty deciding whether to implement SAN, NAS or CAS into your business…and life? Read what Asaro says you should be looking out for, and which storage system may offer the most advantages for you.

  Hitchhiker's guide to storage networking (03 June 2005)
This is the first part of a discussion on these important differences between SAN, NAS and most recently CAS, as well as the far-reaching implications for the future of storage networking.
