Breaking the Storage Array Life Cycle with Cloud Storage: Part III

While Part I and Part II of this series spelled out some of the economic benefits and deployment models of cloud storage, today’s installment will take a more pragmatic look at how to deploy cloud storage in environments that already have traditional storage infrastructure. While replacing traditional storage with cloud storage will break the traditional storage array life cycle, a complete “forklift” replacement may seem a bit of a stretch. A more conservative approach might be to identify data suitable for cloud storage such as secondary copies, backups, off-site data and/or a... (more)

How Cloud Solves the IT Maintenance Dilemma – Part 1

It’s only natural that most organizations split their IT budget between new technology to enhance business operations and maintenance of their existing infrastructure.
