I have a specific requirement where we are upgrading our hardware storage and vendor of new hardware storage has requested few performance counters specifically and these are;
Database read rate MB/sec
Database write rate MB/sec
Vendor is specifically interested in database read and write only other than whole disk read and write operations.
Initially i thoughts counters given below can be used but not sure wether they cover what we need;
PhysicalDisk->Disk Read Rate/Bytes
PhysicalDisk->Disk Write Rate/Bytes
I am recording these counters on SQL Server boxes over the period of 24 hours and then gtting the maximum(and converting from Bytes to Kilo Bytes to MB) value out of it to establish database read and write rate in MB/sec.
Please advise if this is not correct and there are some other couners i need to look at and how to get there answer in MB/sec.
Your help and suggestios are appreciated.
