1 Data Center Management Didik Partono Rudiarto CDCP, ITIL-F, COBIT5, CITM

2 A physical place that houses a computer network's most critical systems, including back-up power supplies, air conditioning, and security applications

3 It is vital that the mission critical Data Centre is designed, maintained and operated with hiavailability and efficiency in mind

4 Fact is most Data Centre's DO NOT MEET the full availability, capacity, safety or efficiency requirements often demanded

5 Standards and Guidelines ANSI TIA-942 Data Center Standard (Telecommucations) BICSI-002 Data Center Standard EN Data Center Cabling Standard ISO/IEC Data Center Cabling Standard The Uptime Institute TUI Tier Standard ISO Environmental Management System ISO IT Governance ISO Information Security ISO Business Continuity EN Management and Operational Information

6 Power Cooling Infrastructure Computing Building system (HVAC, lighting, transport, fire, water supply), Environment Management System, Standard operating procedure, Manuals and documentation, etc.

11 EQUATION #1: As = Ac 1 * Ac 2 * Ac 3 * Ac n EQUATION #2: As = Ac 1 + ((1 - Ac 1 ) * Ac 2 ) single component single redundant EQUATION #3: As = Ac (n-1) + ((1 - Ac (n-1) ) * Ac n ) multi-redundant

12 Redundancy N-Base requirement N+1 redundancy N+2 redundancy 2N redundancy 2(N+1) redundancy

17 Design & Build Consideration

18 Standard and Guidelines There is no world-wide recognized standard for data center environment Best practices (semi standards) Uptime Institute ANSI/TIA-942 (Telecomm) SS507 (ISO International guideline for Business Continuity/Disaster Recovery) Vendors (white papers)

19 Site Selection potential hazard availability proximity selection capacity Infrastructure Location Build or Rent? Building slab-to-slab height building codes floor loading space requirements Security & safety

20 Critical Infrastructure main power detection genset prevention Fire suppression Power UPS suppression Cooling cooling infrastructure air flow

21 What Type of Requirement? Lease or Purchase Existing Data Center Keep apprised of any existing Data Center Inventory Understand the level of infrastructure Convert a Building to a Data Center Know which buildings have the most potential for conversion those with some level of Data Center Centric attributes (close to substation, access to fiber, bunker type construction, etc.) Have an understanding of Cost to Convert Construct a New Data Center Know which sites are best located for a Data Center (close to substation, access to fiber, affordably priced, away from freeways and rail lines, etc.) Have an understanding of Cost to Build

22 Building a New Data Center Cost Ranges $400/sf Basic Infrastructure with No Redundancy Basic power & cooling Unplanned outage disrupts systems & users Scheduled maintenance disrupts availability 99.67% availability Tier1 $ /sf Basic Infrastructure with Redundant Components Single, non-redundant distribution path Unplanned outage can disrupt systems & users Maintenance doesn t disrupt availability 99.75% availability Tier2 $ /sf Concurrently Maintainable Sufficient MEP redundancy even when one of the MEP components has been removed from the infrastructure Unplanned & maintenance outages don t interrupt availability 99.98% availability Tier3 $1500/sf Fault Tolerant Multiple independent & physically separate systems Each system has redundant components & multiple, independent, diverse & active distribution paths Unplanned & maintenance outages don t interrupt availability 99.99% availability Tier4
