First-person (Floyd)
Hello classmates and Dr. Abdelfattah, welcome to week four. A lot of people buy devices for their systems without realizing the specifications and services they provide. For this assignment, I did not know how expensive some of the devices were until I researched different vendors. In networking, switches are devices that are part of the OSI data link layer (2) that transfers data only to the host where it is being addressed. When transmitting data, it will check the destination address to appropriately deliver the packets. The three vendors chosen with specs were:

CDW |
HardDisk Direct |
Office Depot/Max |

Cisco Nexus 9508 (96 port) |
Cisco Catalyst 4507R+E (96 port) |
Allied Telesis AT-X930 (24 port) |

$71,159.99 |
$54,150.00 |
$7,758.99 |

Cisco Nexus 9508 switch-96 port rack-mountable improves performance and efficiency, high density 1/10/10GE compact with 13 rack unit modular chassis. It is a 96x10GBase-T+8x QSFP+. It also has static IP routing, VLAN 4096 for capacity, compliance with IEEE 801.1p, 3,000 watts, 18 expansion slots, front-to-rear air. (New)
Cisco C4507R+E Chas TWO switch is a managed 96 x gigabit SFP – rack-mountable catalyst 4500 has 48 gigabits per slot for all line card slots, allowing the system to scale to 848 Gbps switching capacity. (Refurbished)
Allied Telesis AT-X930-28GPX Layer 3 Switch- 24 Ports Manageable has 10-gigabit ethernet, 10/100/1000Base-T, 10GBase-X, 3-layer supported modular, and built-in power supply. It also works with twisted pair and fiber optic wiring. When supporting optical wiring, the span has a longer distance with high data transmission rates between servers and networks. (New)
For 1,500 employees, the Allied Telesis will suffice for the need of the company because it supports wired and wireless cables along with too many ports that might not ever be used. I will look for the availability of bandwidth, reduce the workload on the host PC, and increase our performance on the network. I will look for a direct connection to our workstation. Using a switch can reduce frame collisions being that switches create collision domains for each connection. A lot of times when purchasing devices or computer hardware, the most expensive does not mean the best, it is all about quality, reliability, and service.
Hello Kelvin,
>I would recommend the Juniper Networks EX Series EX4600 switch, one of its capability features is what the corporate requires.
Would your recommended switch support the corporate headquarters with 1,500 employees? Why or why not?
