SQL DatabaseScalability Considerations
– Database Search Indexes • written & applied to several data sets
– Outcome: performance trade off– The positive:
• Substantially increased data retrieval time• Data download time for registered sets of Daily
and Hourly values now range between quick to nearly instantaneous!!
– The negative:• Substantially slower data entry. Nearly an hour to
load a one hour set of values. Not a sustainable process.
SQL DatabaseScalability Considerations
– Solution: Recent Values vs. Archive• 2 separate sets• Small dynamic set containing recent values
(no indexes needed). This will receive current updates.
• Large static set with full 15/17 yr history of archive values.
– Additional Solution: New platform at Arlington Regional Data Center (ARDC)
• Fail-over power back up• 24/7 sys-op support• Enterprise class data server
ARDC System
• 12 3.5 GHz HT processing cores
• 96 Gb memory
• 12 TB integrated storage for faster IO functions
• MS Server 2008, SQL Server 2008 & ArcGIS Server
Update stream via Unidata Local Data Manager (LDM)
• LDM Connection became active and remained active November 22nd.– Routed from WGRFC through NWS Southern
Region Headquarters and then to UTA.– Extremely dedicated effort by Mike Thompson
of NWS to coordinate the configuration for LDM.

New Project
• Tarrant Regional Water District
• Implement a similar data system to stream multiple data sources.
• MPE, QPF, stream flow, lake levels.
• Purpose: Input for Fort Worth Floodway Model.
• Collaborators: TRWD, NWS, USGS, USACE.
