Interview your university network specialist. Ask how various parts of the system communicates with each other throughout the university. (Q) Given the chance to redesign the existing setup, enumerate and discuss your keypoints for an effective and efficient network environment ideal for the university.
(at least 3000 words)
A network specialist or a network specialist, as defined by the Wikipedia, concentrates on network design and security. Since we are asked to interview our university's network specialist, we request for a discussion with Mr. A. Reyes, university's network administrator. Due to some unexpected circumstances, we aren't able to conduct the interview instead he let us send our queries and he will be the one to answer those questions. A network administrator has a relative role on a network specialist. Based on a post from Wikipedia, A network administrator is a modern professional responsible for the maintenance of computer hardware and software that comprises a computer network. This normally includes the deployment, configuration, maintenance and monitoring of active network equipment.
The first query we have on the list asks, In system development, how various parts of the system communicate with each other throughout the university? In what way? According to him, the best person to asked about system development are the university's programmers, Mr. Fortich and Dr. Mercado. We also include in our list of queries the various components involved in the university's system. Once again, he commented that his not the right person to discuss the details of software components because there are personnel who are responsible for the job. However, he were able to list some specifications for the university's server used. Since he is the one entrusted to maintain the various servers and make sure it runs 24 hours a day and seven times a week. Currently, we have Web Servers hosted in the university using HP ProLiant ML350 Server. The said server has been used for years but it is still stable. This server was set-up in the Network Office. here are the list of specifications needed for this type of server:
• Intel Xeon 3.0 GHz, 3.2 GHz, or 3.4 GHz processors (dual processor capability) with 1MB level 2 cache standard. Processors include support for Hyper-Threading and Extended Memory 64 Technology (EM64T)
• Intel® E7520 chipset
• 800-MHz Front Side Bus
• Integrated Dual Channel Ultra320 SCSI Adapter
• Smart Array 641 Controller (standard in Array Models only)
• NC7761 PCI Gigabit NIC (embedded)
• Up to 1 GB of PC2700 DDR SDRAM with Advanced ECC capabilities (Expandable to 8 GB)
• Six expansion slots: one 64-bit/133-MHz PCI-X, two 64-bit/100-MHz PCI-X, one 64-bit/66-MHz PCI-X, one x4 PCI-Express, and one x8 PCI-Express
• New HP Power Regulator for ProLiant delivering server level, policy based power management with industry leading energy efficiency and savings on system power and cooling costs
• Three USB ports: 1 front, 1 internal, 1 rear
• Support for Ultra320 SCSI hard drives (six hot plug or four non-hot plug drives supported standard, model dependent)
• Internalstorage capacity of up to 1.8TB; 2.4TB with optional 2-bay hot plug SCSI drive
• 725W Hot-Plug Power Supply (standard, most models); optional 725W Hot-Pluggable Redundant Power Supply (1+1) available. Non hot plug SCSI models include a 460W non-hot plug power supply.
• Tool-free chassis entry and component access
• Support for ROM based setup utility (RBSU) and redundant ROM
• Systems Insight Manager, SmartStart, and Automatic Server Recovery 2 (ASR-2) included
• Protected by HP Services and a worldwide network of resellers and service providers. Three-year Next Business Day, on-site limited global warranty. Certain restrictions and exclusions apply. Pre-Failure Notification on processors, memory, and SCSI hard drives.
Here is a listof the servers used by the university:
* HP ProLiant ML350 Server
* Proxy servers
* Enrollment servers
Based on the questionnaires answered by our interviewee, here are some ideas that he have shared that I would discuss on this post. The university's servers are connected in a shared medium which is grouped as one subnetwork. generally, the network follows the extended star topology and was connected to a dual WAN router. This router serves as the load balancer between our two Internet Service Providers of the university. Every workstations are grouped into various subnetworks as in star topology branching out from the servers subnetworks as in extended star opology. As of now, they are using a class C IP Address for assigning private IP addresses. Workstations are configured either statically or dynamically ane are connected via proxy servers which basically filters user access controls on the internet aside from router filtering/firewall management.
