Hi experts,
I saw a few reference sites from Fusion IO and I saw a few experts ran SQLIO and long running queries on Fusion. The result is amazing.
However, some experts suggest the customers should analyze the workload first. If wait events do not show huge wait time in PAGEIOLATCH_SH and WRITELOG, it does not make senses to solve performance issue using Fusion IO.
The perfmon info lists below. My IOPS is about 3,066 on average(The system has 1TB DRAM. I drive is the first LUN for database file). My disk transfers per second on transaction log file is about 262. It seems that there is no IO issue in my system.
But I still find there are many long running queries(more than 10 hours and 90% are database time. In SAP, database time includes network time to transfer data to client) in my system.(I use 10GbE network)
It is impossible to borrow a 15TB Fusion capacity to run POC. So the questions are: 1. "Is it possible to eliminate all IO latencies ex: 0.007 and 0.008 to 0.000?"
2. "Is it possible to reduce a long running queries, ex: 10 hours(It might select more than 1 billion records), to ex: 2 hours or less? Even if my storage performance seems good."
