In the database test, we see the read-write cache delivering better performance in the SX8012R when compared to the other configurations. This is a read heavy test, so we expected to see this type of separation. The read/write cache configuration with SATA SSDs on the read side does a good job outperforming the base HDDs only array.
The QSAN XN8012R in all configurations rips past the base Thecus N8880U-10G results in the database test.
We see nearly identical separations in the OLTP test. The placement of the NVMe SSD makes a big difference.
The email server workload shows where having both a read and write cache can really benefit users by reducing latency under heavy conditions.
Archival File Server
The archive test comes from Dell's performance lab. This test measures performance with a mix of different block sizes, random and sequential data, and a mix of reads and writes. If you use your server for several roles at the same time, this is similar to how your server sees the different workloads with data moving in and out at the same time.
