Hardware selection for IS

Short answer

Hardware selection is critical due to large investment, performance, compatibility, and long-term impact. Factors include application requirements, software compatibility, performance, scalability, total cost of ownership, vendor support, reliability, security, and compatibility with existing systems.

Why do you think that selection of computer hardware for any kind of information system is an important decision for any organization? Discuss different factors that an organization should consider during hardware selection for information system.

Why hardware selection is an important decision

  • Large investment: hardware is a major cost and is hard to replace soon.
  • Performance: a wrong choice makes the system slow or unable to handle load.
  • Compatibility: hardware must support the chosen software, operating system and network.
  • Long-term effect: it limits future growth, upgrades and the life of the system.
  • Reliability and security: failures or weak security hurt business operations.
  • Running cost: power, maintenance and support costs continue for years.
  • Competitive impact: good hardware supports business goals and user satisfaction.

Factors to consider

  1. Application requirements: processing speed, memory, storage, I/O and volume of data and users.
  2. Software compatibility: must run the required OS, DBMS and applications.
  3. Performance and capacity: measured by benchmarks, throughput and response time; also peak load.
  4. Scalability and expandability: easy upgrade of CPU, RAM, disk.
  5. Reliability, availability and fault tolerance: redundant power, RAID, MTBF.
  6. Total cost of ownership: purchase price, installation, training, maintenance and power; not only the initial price.
  7. Vendor reputation and support: warranty, AMC, spare parts, local service in Nepal.
  8. Compatibility with existing equipment and standards (open standards, avoid vendor lock-in).
  9. Security features and ergonomics.
  10. Technology life and obsolescence; energy efficiency and environmental impact.
  11. Network and connectivity needs.
