EMC Virtual Storage Integrator (VSI) is the free vCenter plugin provided by EMC that extends the vCenter UI to add additional EMC-specific capabilities.
We continue to invest in VSI based on what customers tell us they want….
In EMC VSI 5.1, we introduced performance reporting - one of the most recommended features - which is a simple, lightweight way of seeing the view of the VM, the ESX host and the array in vCenter.
While not as sophisticated as something like EMC ProSphere – this VSI capability means that customers who use EMC and VMware together can see vSCSIstats level info, ESXtop level info, and array level info all in one view, and that it is context-sensitive, only showing info based on the objects selected in vCenter
In EMC VSI 5.1, only VMFS data stores were supported, in 5.2 we added support for NFS datastores on EMC VNX and EMC VG gateways.
VSI can be downloaded from EMC Powerlink under Home > Support > Software Downloads and Licensing > Downloads T-Z > Virtual Storage Integrator (VSI)
You can download this demo in high-rez MOV format here.
Have fun, and please give us feedback!

This is great. I like that EMC is not giving up on VSI and putting everything in ProSphere.
I do have one feature I would like to see in VSI or some other tool: When a VM is getting its disk from a VMFS that is getting LUNs from an AutoTier Storage Pool, it would be nice to get a report about what percentage of the VM's disk is coming from which tier in the storage pool.

VSI - Storage Viewer will give you the breakdown of storage by storage pool in MB\GB\TB, but just not as a percentage. So if your LUN (which holds a VMFS datastore and this virtual disk) is spanned across pools (tiers) then it will list each pool and show the amount of storage used by the LUN in that pool. The percentage would just need to be computed manually.

I can't find the link for this anymore, I hate how EMC makes it hard to find its software.

I found it by going to the Search page on the support.emc.com portal (https://support.emc.com/search/#text=*&resource=ST) then filtering by OS -> VMware in the left column. In the results, sort by date (newest to oldest). At the time of this post, it is the second result from the top. The name is "VSI Unified Storage Management 5.2".
Note, this does not show up in the results when searching for VSI.
