Presentation Transcript

  1. CDF Farms Transition • Old Production farm (fbs/dfarm/mysql) • SAM-farm (Condor/CAF/SAM) CSS/SCS/Farms and Clustered System

  2. CDF Old Production Farm • Headnode: cdffarm0Dell 6650, 4-Way Xeon HT, 4GB RAM, 0.5TB usable RAID5+0, SLF303 • 2 Servers:fnpcc (FPS) – dual-Xeon 2U, IDEs, FL731(cdffarm2) – duel-Athlon 4U, SCSI • 98 worker nodes: fncdf75-90,155-170,201-266where 8 readers and 8 concatenators CSS/SCS/Farms and Clustered System

  3. Experimental SAM-Farm • Condor/CAF headnode: fncdf171 (fncdf) • 2 SAM stations: fcdfdata057&055 (cdf-farm1&2) – Polywell 2TB/each, IDE RAID • 29 condor workers in FCC2: fncdf172-200 • 40 new workers in GCC: fncdf267-306 (testing SLF303) CSS/SCS/Farms and Clustered System

  4. SAM-Farm functional requirements • dCAF/Condor headnode(s) • Monitoring and Web services • Many Condor worker nodes • SAM:Station(s)Storage: cache and storeConcatenation CSS/SCS/Farms and Clustered System

  5. SAM-Farm hardware mapping • cdffarm0 will replace fncdf171 as headnode, also monitoring and web • All worker nodes will be converted to Condor and SLF303, using Rocks • SAM stations need new machines since 055 and 057 will be out of warranty soon • Add a 2nd headnode? CSS/SCS/Farms and Clustered System

  6. SAM-Farm SAM station requirements • >4TB/day (~50MB/s avg.) in/outnetwork: multi Gb ports/links • >2TB cache RAID usable, thus ~4TB raw • >2TB store RAID usable, ~4TB raw • Sufficient concatenation power • Single or multiple machines? • 24x7 or 8x5 support? CSS/SCS/Farms and Clustered System

  7. SAM station hardware options • SCSI RAID: 4xDell 2850 ($9k each) ~$36kDual-Xeon 3GHz, 4x300GB SCSIs (and mirrored system drives) • IDE RAID: 4xKoi ($5k each) ~$20kDual-Xeon 2.8GHz, 4x250GB IDEs (and mirrored system drives) • LSI or EMC: 2x2TB (~$40k each) ~$70k4WNs w/ Fibre Channel interfaces • Panasas: 4WNs + Panasas (5TB) ~$35k ** D0 will need similar hardware too….. ** CSS/SCS/Farms and Clustered System
