12 TRIUMF Site Report for HEPiX, SLAC, October 10-14,2005 Raid5: Puzzling I/O results Repeated reads on same set of files (at 600MB/sec) – one or more files will “degrade” – typically after set of 16 8GB files have been read 1000 times. Positive: Read ~2PB during 50 days – averaging about 600MB/sec 8 SATA disks on each of pair of RAID5 RocketRaid 1820A controllers

13 TRIUMF Site Report for HEPiX, SLAC, October 10-14,2005 Unix Backups at TRIUMF Amanda system –Dual Opteron 248 2.2 GHz 2G Memory 16 x400G WD disks ~ 6TB (1.5TB present sys ~ 10day cycle) 2 LSI Mega raid 8 disk controllers Disk based ~1 month of backups –At least 2 full backups with daily incrementals 26 Slot Overland DLT tape library SDLT 600 drive 300G native capacity per tape 150 Linux machines (users: home dir, servers: full)

Rebuilds in background. Used to keep live multiple (daily) RSYNC (via DIRVISH) copies of critical servers (for ~ 1 month). See http://www.dirvish.com/

19 TRIUMF Site Report for HEPiX, SLAC, October 10-14,2005 - Site services (Web, Email, Batch, Windows) all much more stable – new hardware, more memory (typically 4-8GB) in servers - Quad Opteron SUN I/O - using external SATA - still limited below 1 GB/sec - Read 16 8GB files repeatedly – averaging over 600MB/sec for ~2PB - Site “Backup” services still problematic - tape media capacity (outgrow in 2 years) - reliability (is SDLT robust?) - Permanent 10GbE TRIUMF-CERN service by year-end. - ATLAS Service Challenges targets being met for TRIUMF as TIER1 - Started using PLONE as content management for TRIUMF Web Server - Moving some phones to voice-over-IP - Scientific Linux (3 &4) still preferred Linux OS at TRIUMF - Moving away from distributed printing to print/scan-to-email/copy stations Conclusions / Observations
