An IT administrator is responsible for selecting the appropriate storage tier for a new application running on IBM Cloud Power Virtual Servers. They need to consider the workload's peak IOPS and the performance requirements. They are storing data for long-term archival purposes with a minimal I/O load and a peak IOPS requirement of 50. Which storage tier should they choose?
Suggested Answer: A Vote an answer
For storing data for long-term archival purposes with a minimal I/O load and a peak IOPS requirement of 50, Tier 5 storage is the most appropriate choice.
Tier 5 Storage: This storage tier is designed for workloads with low performance and IOPS requirements, such as long-term data archival or infrequently accessed data. Tier 5 offers the lowest cost option and is ideal for scenarios where data is rarely accessed, and there is a minimal input/output operation per second (IOPS) requirement.
Workload Suitability: Given that the workload described involves minimal I/O load and a peak IOPS requirement of 50, Tier 5 provides an optimal balance between cost and the minimal performance needed for such an archival workload.
Reference from IBM Cloud Professional Architect Materials:
IBM documentation on IBM Cloud Storage Tiers indicates that Tier 5 storage is suitable for long-term data storage and archival, where performance requirements are minimal.
Other options are incorrect:
B . Tier 2 storage, C. Tier 3 storage, and D. Tier 1 storage provide higher performance than necessary for the described archival workload, resulting in potentially unnecessary costs.
