Stripe Width Setting

1. Gaja Wrote :-

"Systems that are Hybrid in nature and need to Support large data intensive Transfers , it is Recommended to Set this to at Least 1 MB (or even 4MB in some Cases) "

Qs Would there be any NEGATIVE Effect on OLTP operations in particular if the Stripe Width is OVER-Sized ? NOTE - This is Heavily Loaded Hybrid Systems (Banking Application) which has about 5,000 User processes doing About 5 Million OLTP Transactions in a 5 Hour Window .

Qs Would there be Any Negative Effect on Batch Processing Operations Like Interest Calc ?

2) Gaja Wrote :-
"If the maximum I-O size is 1 MB and the number of Drives in the RAID array is 8 , then Stripe width should be Set to 8 MB and stripe-unit-size/interlace-size at 1MB"

Qs Should one Simply Try to TUNE & Set the I-O Transfer/I-O Size parameters to MAX possible Value and Simply Define the Stripe Width accordingly thereafter ?

Qs What is the I-O Size Tuning Parameter if any on IBM AIX 5.L ? e.g. maxphys is the Corresponding I-O size Tuning Parameterin in Solaris
