Dell PowerEdge R420: Specs and Rack Compatibility 

Data center applications and those used in distant offices may both benefit from the scalable, versatile, and two-socket foundation provided by the Dell PowerEdge R420 rack server. The high-density 1U architecture is compatible with consolidated as well as virtualized systems, and it comes with a variety of features that improve the availability, serviceability and reliability of the system.

Description

The 12th generation Dell PowerEdge R420 server is an excellent choice for use as the foundation of a data center deployment or for installation in server enclosures with limited available space. Even though it just takes up 1 u of space, it is well packed and has excellent engineering. It is capable of supporting up to two Xeon processors, as much as 384 GB of memory, and as much as 16TB of storage space. This rack server's characteristics allow for scalable input and output, making it more than capable of handling memory-intensive and compute-intensive applications and databases. Email, workgroup communication, web hosting, file and print services for online retailers, and high-performance computation are some of the uses for this server.

The Dell PowerEdge R420 is a shelf server with two sockets that offers excellent performance and scalability in a compact 1U rack form factor. The server is manufactured by Dell. It is a perfect match for workloads that need high-performance computing (HPC) as well as applications that require a lot of computational power. Because of its compact size, the R420 is an excellent choice for departmental email, workgroup communication, as well as file and print operations, particularly in circumstances with limited available floor space, such as those found in distant locations of major corporations and public organizations. 

Confidence is derived from a combination of performance and dependability

The R420 is equipped with not one, but two Intel Xeon E5-2400 processors, which together provide an exceptional level of performance. However, powerful processors by themselves are not sufficient to offer s, which together provide an exceptional level of performance. However, powerful processors by themselves are not sufficient to offer balanced performance. In order to avoid performance bottlenecks, compute power must be matched with an adequate amount of memory and I/O bandwidth. The R420 has 12 DIMM slots and two PCI Express (PCIe) 3.0-enabled I/O slots, which together provide a considerable memory footprint and broad I/O bandwidth. This allows it to serve programmes and databases that are memory-intensive as well as data-intensive. When it comes to supporting consolidated and virtualized settings, which is a position that the R420 fits well into, these integrated technological characteristics are also crucial design criteria. Your virtualized applications are safeguarded by the R420's provision of dual, redundant SD media, which also renders your hypervisors robust and fault-tolerant. There is also a hot-plug option for up to four 3.5-inch hard drives or eight 2.5-inch hard drives, hardware and software RAID solutions, and redundant hot-plug power supplies, all of which add to the durability and availability of the system. 

The PowerEdge range of server products

The PowerEdge series is made with the right balance of features and performance scalability so that it can handle demanding workloads in both large and small data centers.

The Integrated Dell Remote Controllers 7 (iDRAC7) with Lifecycle Controller is part of the array of system management tools offered by Dell OpenManageTM. This built-in functionality offers assistance to IT managers in managing Dell servers in physical, virtual, local, and remote settings, whether the servers are running in-band or out-of-band and whether or not a systems management software agent is present. The OpenManage system integration portfolio also interfaces and links to the system security solutions provided by third parties. This allows you to keep your single point of control and make the most of the investments you have already made. OpenManage makes it easier to install, update, monitor, and manage Dell PowerEdge servers at every stage of their lives.

OpenManage streamlines the whole lifecycle of managing your Dell PowerEdge servers by making it easier to install, update, monitor, and manage them.

A hot-plug option for up to four 3.5-inch or eight 2.5-inch hard drives, hardware and software RAID solutions, and multiple hot-plug power systems are also included as additional features that contribute to the system's durability and availability.

Combining performance with dependability in order to instill confidence

  • The R420 is outfitted with not one, but two Intel® Xeon® E5-2400 processors, which provide an exceptional level of performance when combined.
  • However, powerful computers alone are insufficient to provide balanced performance.To avoid performance bottlenecks, there needs to be a good amount of memory and I/O capacity for the amount of compute power.
  • The R420 has a high memory consumption and a large I/O capacity, allowing it to handle both memory-intensive and data-intensive programmes and databases.It does this by adding 12 DIMMs and two PCI Express® (PCIe) version 3.0 elastic slots to its CPUs.
  • These paired technological characteristics are also required to enable centralized and virtualized settings, which the R420 does admirably.
  • The R420 has dual SD media, which ensures the redundancy and safety of your hypervisors, allowing you to safeguard your virtualized workloads.
  • Additional features that contribute to the system's stability and security include independent, hot-plug power stations, up to four 3.5-inch or eight 2.5-inch hard drives that may be hot-plugged, and both hardware and software RAID options.

Performance

It is equipped with a chipset manufactured by Intel and can accommodate up to a total of two Intel Xeon E5-2400 or E5-2400 v2 cpu. There are six memory slots available for each CPU.

Memory

There are a total of 12 memory slots available, and each CPU has the capacity to accommodate six memory modules. A maximum of 384 gigabytes of DDR3 memory with transfer rates of up to 1600 megatransfers per second may be installed by administrators. Up to 192 gigabytes of memory may be supported by a single CPU installation.

Storage

There are two distinct chassis variants available for the Intel Core R420 server. Administrators have the option of selecting between a 4-bay chassis with hot-swap or cabled 3.5-inch drives or an 8-bay architecture with hot-swap 2.5-inch drives for their storage solution. There is support for SATA, SAS, and Hybrid hard drives and solid state drives. It is possible to store up to 16 terabytes of data, and there is also the option to use a drive that encrypts data for you. In order to provide redundant and failsafe support for the hypervisor, an optional Dual SD module may be inserted. Depending on the HD/RAID device that you choose, you have the option of using either hardware or software for your RAID array. Depending on the HD/RAID device that you choose, you have the option of using either hardware or software for your RAID array.

Expansion

In contrast to the PowerEdge R410, which is of the previous generation and only has one PCIe slot, the Dell R420 has two slots for PCIe 3.0 and can support multiple CPUs. In a setup with a single CPU, you will still have access to two PCIe slots, one of which will be of generation 3.0, while the other will be of generation 2.0. The PCIe 2.0 channel becomes a PCIe 3.0 lane when a second CPU is added to the system. You won't have to use any of the PCI slots for internet connectivity or storage controllers because the motherboard has an embedded Broadcom 5720 LOM and a dedicated pocket for the PERC controller. Instead, you'll be able to install additional NICs in the PCIe slots to boost I/O capacity or install more RAID controllers.

Management

Management iDRAC7, in conjunction with the Lifecycle Controller, offers fundamental management capabilities. Administrators have the option of purchasing either an Express or an Enterprise license, depending on the number of management tools they want. Additionally, the system supports OpenManage Fundamentals; however, in order to activate other capabilities, such as the OpenManage Power Center, you will need an iDRAC7 Enterprise license. 

Summary

In conclusion, the Dell PowerEdge R420 computer is an outstanding option for a wide range of applications since it combines high density with a scalable design in a chassis that takes up just one unit of space. Applications include distant or departmental sites of major companies and public organizations; online hosting, electronic commerce, corporate email, workgroup communication, and file and print operations in contexts with limited physical space.
