The PowerEdge R440 and R640 are 1U dense storage chassis for safety and security workloads. It supports single or dual processors.
The PowerEdge R440 is a general purpose platform expandable up to 1TB of memory, up to ten drives and flexible I/O options. The R440 can handle demanding workloads and applications such as data warehouses, e-commerce, databases, and High Performance Computing (HPC).
The R640 system is a powerhouse 2S/1U rack system, which emphasizes performance and reliability in areas such as virtualization, power, thermal and systems management, and usability. It is designed for mid-size to large data centers that require high memory capacity and performance.
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 Technologies 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.
- All tests performed on local storage are Milestone certified.
- Stripe size of 512 was used for video storage virtual drives.
- Servers used for external storage must meet Milestone 's minimum requirements.
