Trying to get employees and managers to carve out time for five days or more for training is difficult because of critical staff shortages and business deadlines. Companies have long recognized that conventional classroom instruction was inefficient and expensive. But today, major business priorities are making it imperative for IT teams to develop and deliver on-line training solutions. Fortunately, improvements have been made in video storage and distribution systems, robust servers and connectivity that make it possible to train people using the Web on a global basis. Distance learners can be connected locally to the company s Intranet or remotely using DSL connections.
Most challenges start with the hardware and software servers.
The four-drive set is written to in RAID level 3 and an Exclusive Or of the four data sets is written to the fifth drive. Large broadcast-quality video files can be striped onto the RAID set without having to be concerned about spanning media. To manage and deliver the video to the users, a new breed of Linux-based solutions has emerged. These open-standard servers allow Intranet or remote access users to instantly and interactively access the video content. This rigid timing is referred to as an isochronous requirement.
