Datacenter 101 provides an overview of key concepts related to data centers including: 1) Data centers are facilities used to house large amounts of electronic equipment like computers and communication hardware. 2) Reasons for data center consolidation include safety during disasters and efficient data storage and hardware virtualization. 3) Physical infrastructure of data centers includes thick walls, HVAC, racks, UPS/generators, and security cameras. Network infrastructure consists of routers, switches, firewalls, peering, bandwidth, and carrier services.

2. What is a Data Center From Wikipedia:- Datacenter is a facility used for housing a large amount of electronic equipment, typically computers and communications equipment

3. Why a Data Center Safety (Nuclear War | Natural Disasters) Consolidation Data Storage Virtualization Hardware Application Services Common Processes High Availability

4. Physical Infrastructure 3 meter thick walls HVAC Cable Trays and POD Cages Racks UPS/Generator Video Cameras/Security Floor(Point|Static) Load

5. Network Infrastructure Hardware: Router|Switch|FW Peering ISP WAN links Bandwidth from Upstream Bandwidth for Downstream ASN Numbers for BGP routing Carrier Neutral - Full Service DC

6. NMS Network Management System Fault Management Performance Management Baselining SNMP: Host Resources SNMP: Network Resources SNMP: Enterprise Logging infrastructure

7. System Architecture Linear Scalability Cheaper | Faster | Reliable Choose any two LP Optimization Least-Cost/User at optimum User Experience for large User numbers

8. Capex and Opex Capacity Planning Capital Expenditure(capex) Right Sizing Operational Expenditure(opex)

9. System Design Define Problems Alternative Solutions e.g. Load Balancer vs App. Config Work as a Team Fully solve problem in one layer Pizza Boxes vs Big Iron Time to market Best Practices TCO vs TBO

10. Data Center Operations System Administrator vs System Operations Individual Efficiency vs Consolidated Processes

11. NOC and SOC Network Operations(NOC) Hardware Network Console access to devices|servers Remote Hands Service Operations(SOC) OS Management Application Management

12. Source to Data Center Development Environment | QA Stage | Training | Production | Disaster Recovery

13. HA Continuum Fault Tolerance Dual power supply, ECC RAM Redundant Hardware Paired devices Graceful Degradation Fail noisily Disaster Recovery Two or more failures MTTR

14. Current Trends High Density Convergence(IP-Telecom) Storage Consolidation & Virtualization OS Virtualization Xen, VMWare, KVM Service Virtualization JVM Microsoft SoftGrid

15. Careers System Operations Unix/Linux vs Windows Network Operations Network|Server Hardware Service Operations Close Development Coordination Development Infrastructure System Architect
