About this book
This book introduces tape virtualization and guides you through the administration of Sun StorageTek Virtual Tape Library (VTL) solutions, including VTL Plus 2.0 and VTL Value systems. It starts with a high‐level explanation of VTL technology, common deployment architectures, and special features. It then provides detailed instructions for carrying out the tasks common to VTL administration according to Sun VTL best practices, including:
■SAN zoning
■using the VTL Console graphical user interface (GUI) and installing copies on management stations
■administering local area network (LAN) connections
■designing, creating, and managing virtual libraries and virtual tapes
■using special features like automatic tape caching, automatic tape archiving, and tape replication
■using encryption and data compression features to best advantage
■handling failback after a high‐availability system has failed over
■reporting
■configuring and using email notifications
Finally, appendices provide additional information that, while not essential to a normal installation, may prove useful in special circumstances.
The document is task‐oriented, organized around the work you have to do rather than around the features or components of the product. Each chapter and section begins with a list of the tasks it contains. Tasks are presented in order, and the steps in each process are numbered, in the sequence in which they are to be performed.
Conditional steps (steps that you perform only in specified circumstances) begin with the condition (“If A ...”) and end with the corresponding action (“... do B”); if the condition does not apply, you simply skip the step. Each task ends with a reference to the next task in the sequence:
Next task: “Installing ...” on page 3.
