Expert Solution

Host Bus Adapter (HBA): It is a circuit board that physically connects a host system (like server) to internal or external storage(like hard disk drives, solid state drives etc). So it means HBA allows a host system to connected storage devices to communicate with each other.
We all aware the Network Interface Card (NIC) is used for connecting a system to LAN , similiarly HBA is used for a system to communicate or connect with storage media.


World Wide name (WWN): It is is an unique identifier used in storage technologies including Fibre Channel(FC), Advanced Technology Attachment (ATA) or Serial Attached SCSI (SAS). It is similiar to MAC address on ethernet card here we can say that WWN number on HBA. WWN is 64-bit address, and if two WWN addresses are put into the frame header, this leave 16 bytes of data just for identyfying the destination and source address.
There are some some types of WNN:

  • Fiber Channel Storage Area Network (FC SAN)
  • Advanced Technology Attachment (ATA)
  • Serial Advanced Technology Attachment (SATA)
  • Serial Storage Architecture (SSA)

AudioCables, Inc., is currently manufacturing an adapter that has a variable cost of $0.60 per unit and a selling price of $1.20 per unit. Fixed costs are $14,000. Current sales volume is 30,000 units. The firm can substantially improve the product quality by adding a new piece of equipment at an additional fixed cost of $6,000. Variable costs would increase to $0.75, but sales volume should jump to 50,000 units due to a higher-quality product.a. What is the current profit...

Suppose Host A wants to send a large file to Host B. The path from Host A to Host B has three links, of rates R1 = 200 kbps, R2 = 2 Mbps, and R3 = 1 Mbps. Assuming no other traffic in the network, what is the average throughput for the file transfer? Suppose the file is 4 million bytes, on average, how long will it take to transfer the file to Host B? Repeat (a) and (b), but...

We are sending a MP3 file of 300,000 bits from Host A to Host B. Host A and B are each connected to a switch S via 100 Mbps links. Assume that each link introduces a propagation delay of 10 µs (microsecond). Calculate the total transfer time of the entire file (from first bit sent to last bit received) for the following: Suppose the MP3 file is sent as one message. S is a store-and-forward device; it begins retransmitting immediately...
