A Dell Unity administrator is troubleshooting a performance issue. They have enabled FAST Cache, but the performance improvement is not as expected. They notice that the FAST Cache hit rate is high, but the overall latency is still high. What could be the reason?

The workload is write-heavy, and FAST Cache is not effective for writes

The system is using too much DRAM cache, causing FAST Cache to be bypassed

The bottleneck is elsewhere, such as the backend disks or the network

The FAST Cache drives are too slow

A Dell Unity administrator needs to enable FAST Cache on a system that currently has no FAST Cache configured. The system has two storage processors and four unused 800 GB SAS flash drives. What is the correct procedure to enable FAST Cache?

Create a new pool with the drives and then enable FAST Cache on that pool

Add two drives to FAST Cache and keep two as spare

Enable FAST Cache using the CLI, specifying the drive count

Add all four drives to the FAST Cache configuration using Unisphere

After enabling FAST Cache, a Dell Unity administrator notices that the cache hit rate is very low. What is the most likely cause?

The FAST Cache is configured on the wrong SP

The system is using too much DRAM cache

The workload has a large active data set that exceeds the FAST Cache size

The FAST Cache drives are too fast

A Dell Unity administrator is planning to deploy FAST Cache for a new file server workload. The workload is expected to have a mix of random and sequential I/O. What is a best practice for deploying FAST Cache in this scenario?

Enable FAST Cache and monitor the hit rate to determine if it is effective

Disable FAST Cache because file server workloads are not supported

Enable FAST Cache only on the pool that contains the file system

Use FAST VP instead of FAST Cache for file server workloads
