If a guest VM is experiencing poor storage performance with a high read ratio, what should be done to improve the situation?

1. Increase the OPLOG.

2. Increase the write cache.

3. Increase SSD capacity.

4. Use HDDs with higher RPM.

The correct answer is: Increase SSD capacity.

When a guest VM is experiencing poor storage performance alongside a high read ratio, increasing SSD capacity can significantly improve the overall storage performance. SSDs provide faster read and write speeds compared to HDDs due to their non-mechanical architecture, which is particularly beneficial in scenarios where read-heavy workloads are prevalent. By increasing the capacity of the SSDs, more data can be stored more efficiently in a higher-performing medium, which can help mitigate issues caused by I/O bottlenecks. This improved performance is especially important when applications are frequently accessing data, as it can reduce latency and increase throughput, leading to a better overall experience for the VM users. In this context, while other options might address different aspects of storage performance, increasing SSD capacity directly targets the benefits that high-read operations can gain from having more resources available, ultimately leading to enhanced performance for the guest VM.
