Slightly off subject

Generally....we are looking for a vendor toolkit that can.....

a) monitor a given server task I/O workload on a given 'real' storage 
subsystem environment/configuration.
b) allow logical modelling changes within the tool to create an 
alternative (theoretical) storage subsystem environment.
c) accurately predict/model the effect to the monitored task of a variety 
of assumed changes to the physical/logical storage subsystem environment.
d) this 'effect' will ideally demonstrate any changes to individual 
Write-I/O's (in milliseconds) and any changes to the tasks overall elapsed 
time. 

Specifically....... 

Tool must provide for monitoring/calibration of tasks on Solaris and 
Windows servers.
Tool will understand (and be able to model) the runtime environments for 
all major storage subsystem suppliers  (minimally EMC and HDS).
Tool will understand (and be able to model) the runtime environments for 
all major SAN switch suppliers (minimally Cisco and Mcdata).
Tool must be able to model the effect of......

        - changing the tasks logical I/O blksize
        - activating EMC or HDS synchronous replication over any required 
distance up to 200 km (based upon DWDM fibre connectivity)
        - different simulated loads (simulated I/O path loading, simulated 
storage cache loading, etc) laid over the monitored workload.
        - all the major switch/storage configuration settings (logical and 
physical).
        - combinations of all the above.

Any help would be appreciated
