## GCC Computer Room A

- Constructed Feb. 2004 – Jan. 2005
- Built for 72 racks of 40 computers each (2880 computers), 840 KW of power & 720 KW of cooling
- 55 racks in room now using 450 KW
- Averaging 80% of projected (10 KW/rack)
- 17 rack spaces & 270 KW cooling remaining

## GCC Computer Room A(cont.)

- FY06 acquisition plans
- CMS: 	240 computers (6 racks)
- CDF: 	280 – 320 computers (7 – 8 racks)
- D0:	280 – 320 computers (7 – 8 racks)
- GP Farms: 40 computers (1 rack)
- Total: 20 – 22 racks, meaning 3 – 5 rack spaces short
- So we added electrical for 5 more racks
- Since we are running at 80% projected, we anticipate <720 KW
- Floor space will be essentially full after FY06 acquisitions
- GPP construction cost: $2.2M

## GCC Power Protection

- CRA has 1,000 KVA UPS (840 KW load)
- Networking uses CRA 1,000 KVA UPS and redundant street power
- CRB and new network room will have same power configuration
- Robot room has 40 KVA UPS + redundant power from CRA 1,000 KVA UPS
- CRA, network & tape robot room can be powered by rental generators
- CRB will also have rental generator backup

## GCC Facilities Monitoring

- Metasys – monitoring...
- Most CRAC units except...
- UPS room second CRAC, tape robot room CRAC; Computer Room A two newest CRAC’s (#8, #9)
- UPS-A
- Switchboards for CRAC’s and CRA panels
- Roof AC in Network/Tech Room
- Provides general alarms and paging
- Accessible easily only from Ops Office ;-( !

## GCC Facilities Monitoring

- PowerLogic operational: GCC CR-A example panels (units: 208 amps)

## GCC Facility Monitoring

- Cameras
- deployed in tape robot room, high-bay hallway, entrance way, network/tech, CR-A, UPS room, electrical room
- 30 day retention

- Temperature and Other Conditions
- Operational
- shunt-trip breaker – hard CR-A power-off if 95°F. exceeded
- UPS for CR-A  – on batteries notifies stakeholder equipment
- Not Operational
- rack temperature sensors – yet to achieve peaceful coexistence between PowerLogic and Python temperature sensor read-out script

## Site Scan Web

- Status and Plans
- ordered: s/w (delivered) and h/w (PC)
- facility maps supplied (for drill-down clickable screen visuals)
- GCC first, LCC, FCC next
- expect to deploy in 4 to 6 weeks
- Approach
- monitoring – *not* control – only in CD: GCC, LCC, FCC,...
- allows Ops personnel to monitor from other than Ops Office – maybe even mobile (gasp!) ;-)
- coexists with Metasys
- paging and alerts more customized to CD needs

## LCC Computer Rooms

- Room 108 (built 2 years ago)
- Full with 670 LQCD computers
- No electrical measure yet, but estimate ~120 KW
- Room 107
- Under construction for 52 racks (2080 computers), 450 KW
- Target completion 6/16/06
- FY06 acquisition: 1,000 computers
- LCC does not have UPS power protection
- LCC can be powered by rental generators
- GPP construction cost: $1.65M

## FCC Computer Rooms

- FCC1, FCC1 Mezzanine (tape robots), FCC2
- Max UPS power available 700 KW across 4 UPS’s (500, 60, 2x100 KVA rated)
- Currently running 565 KVA with 135 KVA remaining
- Floor space not an issue
- Partitioned power across UPS’s is an issue since each UPS powers different computer room areas

## FCC Computer Rooms(cont.)

- FY06 acquisitions
- CMS: 	65 KW
- CDF: 	20 KW
- D0: 	20 KW
- Misc:	?
- FY06 projected power 670 KW
- Will need summer load shed plan since building can consume 800 – 850 KW during summer and generator is limited to 1500 KW
- FY07 projected additions: +126 KW
- We might get through FY07 if we can decommission 126 KW

## Bottom Lines

- GCC
- We believe that GCC computer room A will satisfy FY06 additions
- We believe that computer room B will be ready in time for FY07 additions
- LCC: Room 107 new room will satisfy FY06 LQCD acquisitions with room for 1,000 more computers
- FCC: If we can reduce load by ~126 KW through decommissions, we may make it through FY07, however load shedding may be needed on some days of high heat
