Recommend a backup and data archiving system for the disk array from 6.20.1. Compare and contrast disk, tape, and online backup capabilities. Use Internet and library resources to identify potential servers. Assess cost and suitability for the application using parameters described in Chapter 6. Select parameters for comparison using properties of the application as well as specified requirements.

Exercise 6.20.1

Configure the Sun Fire x4150 to provide 10 terabytes of storage for a processor array of 1000 processors running bioinformatics simulations. Your configuration should minimize power consumption while addressing throughput and availability concerns for the disk array. Make sure you consider the properties of large simulations when performing your configuration.

Day-to-day evaluation and maintenance of operational computer systems involves many of the concepts discussed in Chapter 6. Explore the intricacies of evaluating systems by exploring the following questions.
