QUESTION 100
Exhibit:
Refer to the exhibit. A customer is designing a storage network infrastructure that uses the Cisco MDS 9509 Multilayer Director. The network will consist of 40 application servers, four backup servers, two disk arrays, and one tape library. The application servers each have two Fibre Channel host bus adapters and generate 40 to 50 MBps of throughput. The backup servers each have four host bus adapters and generate 130 to 150 MBps of throughput. The disk arrays each have eight 2-Gbps Fibre Channel interfaces that handle 150 to 200 MBps of traffic. The backup servers will be performing incremental backups of snapshot copies of production volumes from multiple application servers concurrently throughout the day. The backup servers will also be performing full backups of snapshot copies of production volumes from the application servers concurrently throughout the week. The customer is redeploying 16 first-generation Linear Tape-Open (LTO) SCSI drives that were previously direct-attached to application and backup servers. The drives will be deployed using Fibre Channel-to-SCSI bridging devices, and each device will have one 2-Gbps Fibre Channel interface and four drives attached. These drives will go into the new library. Which MDS 9509 configuration would best meet the connectivity needs of this customer?
