io2 Block Express for SAP HANA Storage — Choosing the Right EBS Volume Type
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is deploying a new SAP HANA database on AWS and needs to ensure the EBS volumes are optimized for throughput. Which EBS volume type should be used for the HANA data and log volumes?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
io2 Block Express
For SAP HANA data and log volumes, io2 Block Express (option B) is the correct choice because it provides the highest throughput and IOPS consistency required for SAP HANA's demanding workload. io2 Block Express supports up to 256,000 IOPS and 4,000 MB/s throughput per volume, with 99.999% durability, making it ideal for mission-critical SAP HANA databases on AWS.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may choose gp3 (option C) because it is a general-purpose SSD that can be provisioned with higher IOPS, but they overlook that SAP HANA specifically requires the ultra-low latency and high throughput consistency of io2 Block Express for log volumes, and that gp3's maximum IOPS and throughput are insufficient for large-scale SAP HANA deployments.
Detailed technical explanation
How to think about this question
io2 Block Express leverages a block-level storage architecture with NVMe-based access and a dedicated network path to the EC2 instance, enabling consistent single-digit millisecond latency even under high load. For SAP HANA, the log volume must handle synchronous writes with minimal latency to ensure ACID compliance, and io2 Block Express's provisioned IOPS (up to 256,000) and throughput (up to 4,000 MB/s) meet the SAP HANA sizing guidelines for production environments. In real-world deployments, using io2 Block Express for both data and log volumes ensures that SAP HANA's redo log writes do not become a bottleneck, which is critical for maintaining database performance during peak transaction loads.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

Variation 1. A company is migrating its SAP HANA database to AWS. The database requires high I/O and low latency. Which storage option should be used for the /hana/data volume?
medium- ✓ A.io2 EBS volume
- B.gp3 EBS volume
- C.Amazon S3
- D.Amazon EFS
Why A: The /hana/data volume for SAP HANA requires high I/O and low latency, which is best met by io2 EBS volumes. io2 volumes are provisioned IOPS SSD volumes designed for latency-sensitive transactional workloads, offering up to 64,000 IOPS per volume and 99.999% durability, making them ideal for SAP HANA data files.
