HP-UX & Oracle & SAP Best performance File System and Disk Layout summary(Can be apply for HP-UX & Oracle DB)

** Myself
File System and Disk Layout summary                   
"#OS blocksize for redolog and mirrlog = 1k
#OS blocksize for sapdata and oraarch = 8k"                   
"#SAP Note 1077887
Mount file system option for  sapdata,redolog/mirrlog option on /etc/fstab or dbci.cntl (in MCSG cluster environment)
convosync=direct,mincache=direct,delaylog,nodatainlog
"#mincache=direct (bypass buffer cache on read)
"#convosync=direct (force direct I/O for DB writers)
"#Use for data files and redo log files
For other mount file system for sap and oracle software path (/usr/sap/,/sapmnt/,/oracle/<SID>,and oraarch are use default option
"
*** Because if you mount direct ,mincache in sap or oracle softwae will be very slow in phase install / and usage software path
