IO SIZE PER HOST ( Host performance on HDS )

Hi,

I am struggling to figure out what exact io sizes are being generated by a host, is there any thing in HDS software i.e Tuning manager or CLI that can give me a IO breakdown per host, i.e 4k/64 K.

I reaslize TM/HiCMD has various reports on response time/iops but nothing that says what type of IO is it.

I tried iostat and not quite what i am looking for, dtrace bit more intimidating to use, perfstat on brocade may only give partial picture.

Windows i might try logical disk counter capture.

Let me know if you have any better way to do this.

While back i used 3PAR ( sorry HDS) it had a really nice cmd to give you this info,i am looking for something similar ( histvlan -hostsum & histvlun -metric both)

The reason why i am looking for this to figure out what type of IO a host is generating and how i can tune my enviroment to best suite a host.

Thanks
