Study Notes
Introduction to Information Technology Equipment (ITE) Centers
- ITE centers house information technology equipment
- Equipment varies widely (computers, servers, routers, etc.)
- Supported by electrical power, heating/cooling, alarms, monitoring, fire suppression, and security systems
- Electrical power is crucial; power systems aim to prevent outages
- Complexities vary based on the ITE installation's criticality
- Article 645 of the NEC applies to ITE facilities
Importance of ITE Centers
- Power outages impact ITE sites significantly
- Businesses lose billions annually due to outages (45.7Binindustrial/digital,45.7B in industrial/digital, 45.7Binindustrial/digital,104B-164Btotal,+164B total, + 164Btotal,+15B-$24B in power quality problems)
- Downtime can lead to costly production losses and data corruption
- Recovery time can take days, weeks or months (affecting software personnel)
Differences in ITE Site Work
- Work at critical sites involves strict procedures, policies, and planning (ITE management)
- Continuous uptime of the installation is a priority
- "Human error" accounts for 54% of critical system shutdowns
- Work is often scheduled when load exposure is minimal and data traffic is low
Types of ITE Infrastructure (Tiers)
-
Tier One (N): Most common, smaller, less critical (5-100 racks)
-
May or may not include standby generator, UPS, and dedicated CRAC
-
Susceptible to single points of failure (SPOF)
-
Often less resilient to unplanned maintenance (e.g., switchgear or chilled water system maintenance)
-
Tier Two (N+1): Higher critical role, redundancy built-in
-
Alternate switchgear, power sources, and alternate power paths (to UPSs and CRACs) to accommodate planned/unplanned maintenance
-
Still requires maintenance shutdown
-
Tier Three (2N): Concurrently maintainable, dedicated facility
-
Designed for ongoing maintenance without interruption
-
Two independent sets of equipment/paths capable of carrying a load during maintenance or testing
-
Can also be upgraded to Tier 4
-
Tier Four (2N+1): Fault tolerant, very large, high-mission critical roles
-
Designed to handle one worst-case unplanned failure/event without impact to critical loads
-
Two separate UPS systems with backup capabilities & dual power inputs for all IT equipment
Raised Floors
- Used in medium/large ITE centers
- Constructed from 2x2 ft. cast aluminum tiles
- Provide cold air distribution
- Space for data/power cabling/chilled water
- Integral component of signal reference grounding systems
- Often used for conduits, alarm panels, and signal reference structures (SRS)
ITE Equipment Entry/Exit Procedures
- Restricted access to ITE rooms is common to prevent unauthorized access
- Identification methods vary in reliability (key, card, biometrics)
- Standard procedures include sign-in/sign-out, temporary access badges, security escorts
- Emergency procedures (EPO operation, disconnecting the electrical and HVAC systems) are required for safety and security
Additional factors
- Fire suppression, and smoke detectors are important consideration in ITE facilities
- Proper cabling, power distribution and grounding are necessary
