Cybercrime is on the rise, and almost every data breach is extremely costly for the victim. Thankfully, new Dell PowerEdge servers come with an additional security feature, the OpenManage Secure Enterprise Key Manager (SEKM). SEKM provides full disk AES-256 encryption and external key management.

To find out if using the SEKM feature on Dell PowerEdge servers had any effect on disk performance, we set up a hyperconverged infrastructure (HCI) cluster consisting of three Dell PowerEdge R7525 servers in 2- and 3-NVMe disk group configurations. Then, we captured HCIBench performance metrics twice on each configuration: first without SEKM, and then with SEKM. Our results indicate that adding the extra layer of SEKM data security had a minimal impact on disk performance, even at scale when we added more storage.

Find out how easy it was to transition to SEKM and more details from our study.
