Microsoft Exchange Server has high I/O on VMAX

Hi Experts. We are having write pending issues with our Exchange servers/VMAX. There is a plan to add 80 SATA drive and drain device groups. Hopefully, performance will improve.
What could some of the issue for poor performance (high I/O's) be with Exchange and VMAX?

so you are asking what caused high IOPs from the Exchange.

Hi Busbar. Yes. We want to monitor its performance. So any info on it would be appreciated. Thank you qaurav05 that document link is great!

If you want to monitor Exchange IOPs you can check the disk reads/seconds and writes/seconds, more is here
however it might be simply because your users are performing heavy transactions on the Exchange so you might need to add disk so nothing is wrong with Exchange itself.
