A mainframe customer would like to receive a proposal for a mainframe storage system with 120 TB raw capacity. The 
mainframe server load is not too high， and they need hard disk drives with the lowest possible power consumption to keep operating costs low. The customer will notincrease the capacity of their mainframe applications in the future but rather invest later into their System p servers. 
Which of the following solutions best meets these requirements at the lowest cost（）

单项选择题A customer has the following non-virtualized servers： - three Exchange servers， each with 2.8 TB database  - five System i Domino servers， each with 2 TB database  - 20 TB usable capacitySun SAP cluster  - 70 TB usable capacity of System p requirement  - annual growth rate of 12 TB usable capacity per year   What is the most cost-effective solution for three years（）

A.IBM System Storage DS5020 with 300 GB drives
B.IBM System Storage DS5300 with 300 GB drives
C.IBM System Storage DS8700 with 300 GB drives
D.IBM System Storage DS5020 with 1 TB SATA drives

单项选择题A customer has an existing IBM System Storage DS8700 2-way model with 8 mega packs of 300 GB disks and 16 fibre ports.  How many additional fibre ports and mega packs can be installed in the base frame（）

A.16fibre ports and 0 mega packs
B.4fibre ports and 8 mega packs
C.8fibre ports and 4 mega packs
D.12fibre ports and 0 mega packs

单项选择题During the pre-installation planning of a customer’s recently purchased IBM System Storage DS8700 the port configuration， cabling， and disk layout were discussed.  What other topic should be discussed in this solution review（）

A.LPAR capacity planning
B.logical volume configuration
C.data migration process
D.audit hosts for HBA worldwide port names

单项选择题A customer has installed an IBM System Storage DS8700 with 20 TB of storage， two-way processor version， 32 GB cache， and 16 Fibre Channel ports. The customer is beginning to experience throughput performance issues.  To address this performance consideration with minimal cost to the customer， which of the following should be the FIRST step to resolve the problem（）

A.add an expansion frame with additionalFibre Channel ports
B.increase the amount of storage by 20 TB
C.conduct a Disk Magic study to identify the source of the performance issue
D.add additionalFibre Channel ports to the existing DS8700

单项选择题The storage specialist needs to prepare an IBM System Storage DS8800 proposal including 64 host ports. The offer needs to meet the lowest possible price.  What is the minimum number of I O Enclosure Pairs PCI-E for this configuration（）

A.one I/O enclosure pair PCI-E
B.two I/O enclosure pairs PCI-E
C.four I/O-enclosure pairs PCI-E
D.eight I/O-enclosure pairs PCI-E
