I have had a busy week in Hong Kong, with several of our executives providing an update for some customers and partners. There was a lot of interest in a new option that we will announce for our Hitachi Content Platform that will address the challenges of BYOD. BYOD is a great enabler for user [...]

In 2005 Thomas Friedman published his book, “The World is Flat” where he describes how globalization has changed the economy thanks to the Internet and workflow software.

Data has to remain un-duped until time can be scheduled, during off-peak hours, for this task. This results in having to pay a capacity consumption “tax,” plus it works against [...]

VMware provides a rich menu of storage services, which can be used to enhance commodity storage systems. However, VMware can provide more services for the application if they can offload the cycles that are used for storage services to intelligent storage systems. VMware realizes this and provides VAAI to offload services like SCSI reservation, disk [...]
