Bằng cách tạo ra một kế hoạch dự án như một trong những nhìn thấy trong hình 1-15, bạn có một cách để theo dõi các nhu cầu ngân sách của bạn, tài nguyên cho dù các nguồn lực lao động thực tế hoặc kỹ thuật viên phần cứng dựa trên máy chủ và nhiều khía cạnh khác của cán ra một giải pháp cao sẵn. | Chapter 1 Introduction to High Availability Clustering and Load-Balancing Technologies 23 that they didn t order the separate switch for the Management VLAN. Although this was a painless oversight my hope is this book can eliminate most of these types of errors from ever occurring. Creating a Project Plan By creating a project plan like the one seen in Figure 1-15 you have a way to keep track of your budget needs your resources whether the resources are actual workers or technicians of server-based hardware and many other aspects of rolling out a Highly Available solution. Make no mistake creating a Highly Availability solution is no small task. There is much to account for and many things need to be addressed during every step of the design during the setup and roll out of this type of solution. Having at least a documented project plan can keep you organized and on track. You don t necessarily need a dedicated project manager unless you feel the tasks are so numerous and spread over many locations and business units that it warrants the use of one but you should at least have a shared document for everyone in your team to monitor and sign off on. Pilots and Prototypes You need to set up a test bed to practice on. If you plan on rolling anything at all out into your production network you need to test it in an isolated environment first. To do this you can set up a pilot. A pilot is simply a scaled-down version of the real solution Figure 1-15. Example of a sample project plan with Project 2000 24 Windows Server 2003 Clustering Load Balancing where you can quite easily get an overall feel of what you ll be rolling out into your live production network. A prototype is almost an exact duplicate set to the proper scale of the actual solution you ll be rolling out. This would be costly to implement based on the costs of the hardware but if asked at least you can accurately say you could set up a pilot instead to simulate the environment you ll be designing.
