A customer wants to consolidate storage from four IBM System p servers and one large IBM System i server on a high end disk subsystem. The customer does not have a SAN installed. The customer will require approximately 24 TB of capacity for System p and 20 TB of capacity for System i. The customer states that performance of the System i system is most important. Capacity， multi-path access， and replication functions are important for the System p servers. Which solution best satisfies the customer requirements（）A、IBM DS8700 with 600 GB drives for the System p， 300 GB/15k drives for Systemi； and advanced functions for System p capacityB、IBM DS8700 with LPAR， 300 GB/15k drives and RAID 10 for Systemi； and 600GB drives with RAID 5 and advanced functions for System p capacityC、IBM DS8700 with advanced functions， 300 GB/15k drives and RAID 10 for Systemi performance； and 600 GB drives and RAID 5 for System p capacityD、IBM DS5100 with Enhanced Remote Mirror， 600GB/15k drives and RAID 5 for System p； and 300GB/15k drives and RAID 10 for Systemi
