What's the new size limit for local LUNs with ESXi v5.1? My goal is to spin up a Dell 2950 with 6 x 1 TB SATA via RAID 10. I plan to present this RAID 10 array to my ESXi install and in return present it to my StarWinds install which will be a VM on top of the ESXi. Then I'll carve out sections of this and issue to a cluster as centralized storage. My goal is to have two other ESXi servers use this as centralized storage in a cluster. I'll also use the VM on the 3rd ESXi server (the centralized storage one) to I guess manage the cluster for I assume for the other two to be HA a third one will handle the heartbeat/monitoring of the other two. I'll use a USB memory stick for my centralized storage ESXi install and boot from it.. That way I have more storage to work with... But.. I want to boot it via ESXi so need to know what the local LUN limitation is. As I understand with 6 x 1 TB drives I'll get 3 TBs of storage. The other two ESXi servers will simply be 1U servers with 2 x 500 GB SATAs that ESXi will be installed onto.
