You can do it via command line, or in the VSphere client. You can also check for disk read/write latency from the same page(just click advanced and change data sets).
Update on the SAN shopping situation:
After getting all the quotes in from NetApp, Pure, and Nimble, we were so impressed with Nimbles quote that we decided to go with a bigger controller. Instead of the CS300(30k IOPS), we decided to go with the CS500(90k IOPS) instead. This unit has 2.4TB flash and 36TB raw storage.
We also were able to reach out to a few existing Nimble customers(Not recommended by our Nimble Sales team). We found them via various forums and reached out through private messages to set up calls. We got some very good information. I will share one of their stories.
An IT head at a company in Boston, MA was a NetApp shop for 6-7 years and started SAN shopping last year. He ended up doing a POC on 2 devices. The first was an All Flash NetApp array. The second was a Nimble CS400. He stated that the Nimble CS400 was literally 4 times faster than the All Flash Netapp array and the decision to go with Nimble over Netapp became a no brainer...especially as the cost was significantly cheaper. He ultimately purchased the CS500 which has been in production with zero issues since late last summer.
We also asked about having multiple plugins into VSphere seeing how we are adding to our environment and not removing the NetApp at this time and he was doing the same thing without issue. This something the Nimble team said "should not" be a problem but that they were not sure and would get back to us. We will be starting our POC the first week in May. We will also be doing a local replication to our second CS500 and once done, will ship it to our London office.
I will keep you all posted on our progress as soon as the POC starts. My goal is to put so much info on here, that anyone looking for info will get their fill. I will also be providing real time data benchmark results from our production environment for everything(VM boot time. SQL, Exchange, disk read/write latency, CPU Co-Stop, etc...) from both our current NetApp and our new Nimble CS500. If any of you want more info, please feel free to PM me.
acidpaintball - Conclusion.. Nimble is terrible, which it isnt near end of life yet and we are looking to purchase a new device from EMC or Netapp to replace it..

Once we looked at the Graphite data it was pretty clear the NetApp systems of our customer were running at their maximum performance capabilities during the backup window. True, the performance is still not great, but at least now we know what the root cause is.
