A community hospital has expressed interest in consolidating their legacy Intel servers onto virtual machines with VMWare ESX.  They will migrate most of their 2-way processor servers to two x366’s and have confirmed they would like to use a SAN.  The IBM specialist visited their datacenter to verify their environment and met with the Systems Admin.  Which of the following questions is most critical to verify the solution can be implemented？（）

A.Is there a need for direct attached SCSI？
B.Do any of the legacy servers require access to a parallel port or other I/O device not supported by ESX？
C.Will Flashcopy be required to duplicate VMs？
D.How much do they expect their storage to grow within the next two years？
