A customer wants to migrate their SAP HANA database to AWS and needs to ensure that the EBS volumes for /hana/data and /hana/log are configured for maximum throughput and low latency. Which EBS volume type should be used for /hana/data?
io2 provides low latency and high IOPS suitable for HANA.
Why this answer
For SAP HANA workloads on AWS, the /hana/data volume requires the highest level of IOPS and low latency to support real-time data processing. io2 Block Express volumes provide up to 256,000 IOPS and sub-millisecond latency, making them the correct choice for /hana/data. io2 volumes also offer 99.999% durability, which is critical for SAP HANA database consistency.
Exam trap
The trap here is that candidates often choose gp3 (Option C) because it is the default general-purpose SSD and can be provisioned for high IOPS, but they overlook that SAP HANA certification for /hana/data mandates io1 or io2 volumes to guarantee the consistent low latency and durability required for production workloads.
How to eliminate wrong answers
Option A (st1) is wrong because st1 is a throughput-optimized HDD volume designed for large sequential workloads like big data and log processing, not for the random I/O and low-latency requirements of SAP HANA /hana/data. Option C (gp3) is wrong because while gp3 offers baseline performance and can be provisioned for higher IOPS, it does not match the maximum throughput and sub-millisecond latency of io2 Block Express, and SAP HANA certification for production /hana/data specifically requires io1 or io2 volumes. Option D (sc1) is wrong because sc1 is a cold HDD volume designed for infrequently accessed data with the lowest cost, and its performance is completely inadequate for the high IOPS and low latency demands of SAP HANA /hana/data.
