MACHINE ROOM DESIGN
  • A presentation to
  • The System Administrators Guild of Ireland
  • by
  • Dónal Cunningham
  • www.sage-ie.org
  • September 2002

2
Topics
  • Rationale
  • Building
  • Access
  • Power
  • Environment
  • Connectivity
  • Conclusion

3
Rationale
  • Why are you (thinking of) building a machine
    room?
  • Co-location/co-hosting
  • Costs
  • Recovery of costs

4
Building I
  • Building ownership, leases
  • Flood plains
  • Construction plans
  • Never build a machine room in the basement...
  • Will it hold people as well as systems?

5
Building II
  • Existing electrical system
  • Existing aircon capacity
  • Security
  • Chill-out zones
  • Existing walls supporting?
  • Doors quantity and size

6
Building III
  • Layout of room
  • Watercourses
  • Dont fill all available space with cabinets.
  • Where do you open boxes?
  • Where do you keep spares/unpacked boxes?

7
Access I
  • No lifts, no machine room
  • Make sure lifts stop at floors with machine
    rooms
  • Trolleys/lifters
  • Ramps/stairwalkers
  • If all else failsIgors

8
Access II
  • Raised floors vs. suspended cable trays
  • Make sure floors can support weight of equipment
  • Make sure trays can support weight of cables
  • If using structured wiring, cables regroup near
    MDF

9
Access III
  • Ducting for electrical/environmental/data
  • Beware the Gardener
  • Links to other locations/buildings

10
Access IV
  • Sufficient space between cabinets
  • Large devices (tape libraries, E6500s)
  • Room for loading/unloading

11
Power I
  • Building capacity
  • Single phase, three phase
  • AC comes in two flavours
  • DC for telco gear
  • Distribution blocks plug types

12
Power II
  • UPS - do you need it?
  • UPS can fail too
  • UPS on different phases
  • Distribution blocks from disparate UPS
  • Scram switches

13
Environment I
  • Is this a comfortable environmentfor systems?
  • What about people?
  • Labs/build areas
  • Monitor environment

14
Environment II
  • Heat - get BTUs from vendors!
  • Spread BTU load
  • Humidity
  • Fire suppression
  • ESD

15
Environment III
  • Noise levels
  • If you can see water, its too late
  • Who monitors the alarms?
  • Worthless unless tested
  • Procedures

16
Connectivity I
  • Structured wiring
  • Copper and Optical
  • Switches in rows vs. in MDF
  • Wiring standards - Cat5, Cat5E, Cat6
  • Ooh, the pretty colours...

17
Connectivity II
  • ISP access
  • PSTN, ISDN (BRI and PRI), DSL
  • Interfaces on routers (and spares!)
  • Spares on site

18
Connectivity IV
  • LABEL EVERYTHING!
  • (especially the external connections)
  • Procedures

19
Conclusion
  • Questions
  • References
  • Horror stories
  • Next meeting - 8th of October
