Security: Physical security access to the site is usually restricted to selected personnel. Controls typically include layered security systems, often starting with fencing, bollards, and mantraps. Video camera surveillance and round the clock security guards are commonplace if the data center is large or contains sensitive information within any of its systems. Additionally, fingerprint recognition mantraps are becoming more and more prevalent. Maintenance: Generally, most data center sites require one or two preventive maintenance (PM) visits per year. However, more PM visits may be required if the physical infrastructure equipment resides in a hostile environment (i.e. high heat, dust, contaminants, vibration). The frequency of PM visits depends on the physical environment and the business requirements of the data center owner. The system design of the component may also impact the frequency of PM visits. Often the number of visits is based on the manufacturer's recommendations. B. Facility Building / Svstems Modifications: Using these general parameters for an initial broad -brush assessment, the Santa Ana City Jail building poses numerous challenges for integrating a new state-of-the-art design. Based on the site location, compartmentalized / non -cohesive functional use areas, and minimally -purposed electrical and mechanical systems that are designed for personnel air conditioning only and not for heat generating hardware, the facilities are generally not accommodating to the demanding requirements for a typical data center. As is, it appears the proposed space (eight dayrooms) for reuse as a data center will require extensive upgrades. The overall placement within the facility will be complicated and extremely challenging to utilize the majority of the existing multi -story building. While the building is large with significant space, there are very few areas that meet the overhead space requirements necessary for temperature control. There will be significant added costs for structural risks and creating portals / paths for wiring and equipment access. The most efficient and cost-effective designs tend to be single story buildings with open floor plan and rack layouts4. The minimum ceiling criteria is 12' with a preferred dimension of 14' or better. By removing the tiers / mezzanines, a 15' floor -to -ceiling dimension would be available. Alternatively, first floor space with a 15' high elevation is available and depicted on the building plans. This also provides additional space for overhead cable trays and sufficient lighting. Given the Jail's excellent condition, it would make an eye-catching facility if the interior layout was more compatible with typical data center design requirements. Unfortunately, very little of the 668 rooms contained in the Jail are usable for data center hardware and equipment. However, the existing Administration area can continue to serve as originally intended, and eight high ceiling open dayrooms within the third and fourth floor housing units could be partially modified for this purpose. Unfortunately, the majority of the building's 668 rooms would be wasted space. In other words, the Jail contains a total of 168,277 square feet and Vanir has determined that 12,856 square feet, or 7.6% of the total area, meet the partial design requirements of a data center and could be converted accordingly. Site: - Locate data center equipment on third and fourth floors to reduce risk of flood damage. - Do not locate equipment near mechanical or electrical equipment, or the Food Service area if still operational after conversion. - Design utility and power access in a manner that assumes an attack will occur. 118 65A-125
