T Models are Designed to give you a Cluster Solution 

If clustering (think federation) is what you want to do, you will want to get PowerStore T models, like the 5000T. You'll get improved management and monitoring with clustering, as well as the ability to move data between appliances within a single cluster.

If you are looking to run a virtual machine, then look at the PowerStore X models.  These models are designed with an Active - Active architecture, giving both nodes access to all the drives and storage resources.

The 5000T and 5000X models differ from the 1000 and 3000 by having all four NVRAM drive slots filled and memory goes up to 1,152GB. Mix models if you like when creating clusters and choose to match your 5000 with models above and/or below it.
