The R540 is a 2U dense storage chassis for safety and security workloads. It supports single or dual processors. The R540 chassis supports 16 x 3.5" hard drives. It a single disk controller for both Boot and Storage capacity.
The test results are based on a model in which the constant-bandwidth safety and security video traffic remained unaffected during select storage failure scenarios, such as disk rebuild, failing processors, and failing network paths.
We performed all tests with disk drive failures, node failures, storage process failures, or NIC failures to ensure a worst-case scenario for all sizing parameters.
Dell EMC recommends using RAID 6 with local storage to accommodate the disk rebuild duration. For example, in the Dell EMC Safety & Security Lab , a disk rebuild in a 16 x 10 TB disk system takes at least 36 hours to complete when 10TB of data and 37.5 MB/s (300 Mb/s) of write are in place.
