Generic Data Center Operational Criteria resource for 14 offices in 8 states, the key to establishing a functional and appropriate data center design is to have a clear understanding of what types of data need to be gathered, where it will be stored, and how it will be used. Therefore, the first order of business is for the City is to meet with potential partners including the IT Team2. Together they will focus on: ■ how, and from what resources, the data will be maintained; • what the projected minimum and maximum storage needs are expected to be; ■ how the data will need to be manipulated to provide a usable product; and, • how the product will be formatted and delivered to its users? Building on this information as a foundation, the City can determine the type and size of the hardware resources required. They will also calculate the electrical and mechanical equipment needs to power and cool the center. Once a well-founded set of requirements is available for the design effort, they can be appropriately viewed in the context of what currently exists within the Santa Ana Jail and what needs modification. This information is required to best meet consumer needs and determine what must be provided to make the space suitable for data center use. Generally, a data center requires flexibility (the ability to support new services without a major infrastructure overhaul), scalability (the ability to support fast / seamless growth without major disruptions), and high availability (minimizing single -point failure with fault -tolerance against hard failures to maximize uptime). The ideal data center facility is a single -floor, stand- alone building with the equipment in a centralized space. The space should be an open floor / cohesive use layout with adequate electrical and mechanical systems to power and cool the center equipment. It should also allow for the modularity needed for the center to change and adapt with technology trends systematically by adding data modules or updating equipment as needed. Data center designs typically use a "rack unit" as the primary planning factor to estimate the necessary space, cooling and electrical power requirements. Each configuration should reflect total power, space, and floor -loading demands per rack across the layout. Just recently, rack designers, have developed a taller, wider and longer rack for more efficiency and emerging hardware. This is the primary reason why it is so important for the data center design team to identify and define the IT parameters at the outset of the project. It has been reported that recent trends show data centers older than seven years are typically obsolete. In some cases, the user's needs have grown beyond their data center's capabilities in as little as two to three years requiring relocation or expansion. Typically, for a data center investment to last 10 to 15 years, the design should be specifically tailored to encompass a business's current and future needs, or provide a design which allows for the flexibility to adapt to the growth and changes in the industry. 116 65A-123
