A customer needs a test bed server to run 64-bit modeling， simulation， and other technical applications which require 2-way processors and 6GB RAM in a clustered mode.  They also indicated that this server might be used to run 32-bit applications.  Which of the following servers should be recommended to meet the requirements at the least cost？（）

A.Is high availability required？
B.Which network protocols are going to be used？
C.What are the expected I/O’s per second to the storage？
D.To what network infrastructure is the storage pool connected？

A.Ability to add expansion cards
B.More Citrix users per server reduces management costs
C.Ability to run on both 110V and 220V power input
D.Ease of deployment due to infrastructure integration
E.Physical sharing of the SCSI Storage Expansion Unit
F.Fewer cables and better cable management due to modular switches
G.Integrated HBAs for SAN connectivity

A.Yes， the internal LSI SCSI adapter has no write cache.
B.Yes， the internal LSI SCSI adapter is unreliable.
C.No， the downtime to install the card and reformat the drives would be cost prohibitive.
D.No， there will be no performance benefit， because drive performance is the bottleneck.
