Dell PowerEdge R420 Rack Server - System Overview

Description

The 12th generation Dell R420 rack server is ideal as a base for a data center deployment or for use in space-constrained server enclosures. It may only occupy a 1u space but the R420 is densely packed and well-engineered. It supports up to two Xeon processors, up to 384GB of memory, and up to 16TB of storage. With scalable I/O features, this rack server is more than a match for memory-intensive and compute-intensive applications and databases. It's also preferred for email, workgroup collaboration, web hosting, ecommerce file and print, and high-performance computing.

Performance

Up to two Intel Xeon E5-2400 or E5-2400 v2 processors can be installed on this server, which features the C602 chipset.

Memory

There are 12 memory slots total, with each processor supporting six memory modules. Administrators can install up to 384GB of DDR3 memory supporting transfer speeds of up to 1600MT/s. A single processor deployment will support up to 192GB of memory.

Storage

Administrators have options for storage, either four 3.5-inch drives or eight 2.5-inch hot swap SFF drives. SATA, SAS, and Hybrid HDDs and SSDs cabled or hot swap drives are supported. Depending on your choice of storage, HP states a maximum of 16TB is supported. Self-encrypting drives are also available. An optional Dual SD module can be installed for redundant, failsafe hypervisor support. Both hardware and software RAID options are available depending on your choice of RAID controller.

Expansion

The R420 provides two PCIe 3.0 slots with dual processors, compared to just one PCIe slot on the earlier generation PowerEdge R410. In a single processor configuration, you still have two PCIe slots available with one gen 3.0 and one gen 2.0 PCIe slot. The second processor changes the 2.0 lane to a PCIe gen3 lane. An embedded Broadcom 5720 LOM and a dedicated slot for the PERC controller ensure you don't use any PCI slots for network connectivity or storage controllers and can add additional NICs in the PCIe slots to increase I/O or install additional RAID controllers.

Management

Basic management is standard but you can update to iDRAC7 with Lifecycle Controller with the purchase of an Express or Enterprise license. OpenManage Essentials is also supported on the system but to activate additional features, including the OpenManage Power Center, you'll need iDRAC7 Enterprise with Lifecycle Controller.

Summary

The Dell R420 is an excellent choice or for a variety of applications offering high density with scalable architecture in a compact 1u chassis. Applications include; departmental or remote sites of large businesses and public organizations, web hosting, e-commerce, departmental email, workgroup collaboration, and file and print in space constrained environments.
