DRAFT Referring to 50% Detailed Design Drawings and Comment No 68 from Kaust, such as “Provide 90 days recording for all systems i.e. IDAS and IP-CCTV and SACS Cameras “. After detailed discussions with the designer and security sub-contractor, your above request impacts the scope of work as follows; 1. The approved FSD being a part of the Kaust approved Project Proposal mentions in para 5.12 that, “Recorded videos of both fixed and PTZ cameras of the associated alarmed IDAS zone shall be stored and available for investigative viewing upto thirty (30) days from the date the video was captured. 2. According to recently revised security directives, HCIS para 4.2.16 also requires the same 30 days as mentioned above. (Note that HICIS has been changed from 90 days to 30 days.) 3. Changing the storage capacity from 30 to 90 days in addition to 50% free space, is an exponential increase which effects not only the quantity of servers, but also the number of racks and ultimately the size of the room. 30 day storage requires a storage capacity of approximately 430 TB; whereas 90 day storage shall require approximately 2400TB space. Thus almost 80U of extra rack space shall be required and the existing room does not have enough space.
