ESXi v5.1 local LUN size limitation

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.

thanks.

VMFS-5 now supports datastores up to 64TB in size. VMFS-5 is the new VMFS system in VMware vSphere 5.x. which includes ESXi 5.1.

see this document

Configuration Maximums for VMware vSphere 5.0

So your 3TB RAID 10 array is within these limits.

Personally, I would use USB flash drives or SD cards to install ESXi onto.

I'll look at getting the USB flash drive add on versus using a memory stick... But..  Sounds like my configuration will work.

Thanks.
