Product identity

The Dell PowerEdge R640 is a 1U rack server built for dense virtualisation and high-performance computing. It ships with dual Xeon Gold 6148 processors, 512GB of DDR4 memory and 30.72TB of enterprise SATA SSD storage.

Included changes

Eight hot-swap 3.84TB SSDs sit behind a PERC H730 RAID controller with 2GB non-volatile cache. Dual redundant power supplies allow replacement without downtime. A Broadcom BCM5720 quad-port 1GbE controller and iDRAC9 Express remote management come pre-installed. Windows Server 2022 Standard 16-core licence is included.

Before ordering

Drives and memory modules are supplied separately and require installation. Verify that your rack provides 1U space and compatible rails. Confirm power infrastructure supports redundant supplies. Ensure operating-system licensing matches the 16-core entitlement.

Questions about this item

How often will the PERC H730 RAID controller's 2GB NV cache need replacement?

The PERC H730 12Gb/s RAID controller includes 2GB NV cache. This non-volatile cache protects data during power loss and has no user-serviceable parts or scheduled replacement interval.

Which component limits sustained throughput first, the PERC H730 12Gb/s controller or the 8 x 3.84TB SATA III 6Gb/s SSDs?

Each 3.84TB SATA III SSD is capped at 6Gb/s. With eight drives, the aggregate device limit reaches the PERC H730 12Gb/s controller ceiling first under sustained sequential workloads.

How much heat and power do the dual Xeon Gold 6148 20-core CPUs produce when running all day?

Dual Xeon Gold 6148 20-core 2.40 GHz processors with 3.70 GHz turbo draw significant power under full load. Redundant hot-swap power supplies and iDRAC9 remote monitoring help manage thermal output continuously.
