A customer is planning to implement a database server for their high volume online business.  Downtime at any point represents a significant loss of revenue， so performance and high availability are extremely important.They requested a 4-way configuration with 8GB RAM and four gigabit Ethernet connections.Which of the following solutions is the most appropriate？（）

• A、x445 4-way Xeon DP machine using 16 x 512MB DIMMS， ServeRAID 6M adapter and Ultra320 15K Hard Disk drives in a RAID-1 set with an additional two BroadCom Gigabit NICs
• B、x366 4-way Xeon MP machine using 16 x 512MB DIMMS， ServeRAID 6M adapter and Ultra320 15K Hard Disk drives in a RAID-1 set with an additional two Intel Gigabit NICs
• C、x445 4-way Xeon MP machine using 16 x 512MB DIMMS， ServeRAID 6M adapter and Ultra320 15K Hard Disk drives in a RAID-1 set with an additional two BroadCom Gigabit NICs
• D、x445 4-way Xeon DP machine using 16 x 512MB DIMMS， ServeRAID 6M adapter and Ultra320 15K Hard Disk drives in a RAID-1 set with an additional two Intel Gigabit NICs
