Our application Canary has approx 750 clients uploading to the server every 10 mins, that's approx 108,000 gzip tarballs per day writing to the /upload directory. The parser untars the tarball which consists of 8 ascii files into the /archives directory. /app is our application and tools (apache, tomcat, etc) directory. We also have batch jobs that run throughout the day, I would say we read 2 to 3 times more than we write.
Since we have an alternate server, downtime or data lost is somewhat acceptable. How can we best layout our filesystems to get the most performance. directory info -------------- /app - 30G /upload - 10G /archives - 35G HW info ------- System Configuration: Sun Microsystems sun4v Sun Fire T200 System clock frequency: 200 MHz Memory size: 8184 Megabytes CPU: 32 x 1000 MHz SUNW,UltraSPARC-T1 Disks: 4x68G Vendor: FUJITSU Product: MAV2073RCSUN72G Revision: 0301 We plan on using 1 disk for OS, the others 3 disks for canary filesystems, /app, /upload, and /archives. Should I create 3 pools, ie zpool create canary_app c1t1d0 zpool create canary_upload c1t2d0 zpool create canary_archives c1t3d0 --OR-- create 1 pool using dynamic stripe, ie zpool create canary c1t1d0 c1t2d0 c1t3d0 --OR-- create a single-parity raid-z pool, ie. zpool create canary raidz c1t1d0 c1t2d0 c1t3d0 Which option gives us the best performance? If there's another method that's not mentioned, please let me know. Also, should be enable read/write cache on the OS as well as the other disks? Is build 9 in S10U2 RR?? If not, please point me to the OS image on nana.eng.
