VMs over a single iSCSI
connection
• Utilizes one host connection
on the storage array*
• Leverages jumbo frame
support (jumbo frames should
be enabled on the physical
NIC in the parent partition)
• Reduced isolation of LUNs (all
VMs and the parent partition
potentially have read/write)

hot add of
additional disks for the VM (to
