Achieving high data center performance

Data center performance is often tied closely with memory capacity. The Dell PowerEdge M630 boasts an advanced memory capacity of 24 DDR4 DIMM slots, and up to 4 SSD drives. This gives the server enough capacity to handle High Performance Computing. In addition, its Intel Xeon E5-2600 v4 processor makes the M630 rank highly in performance capabilities for your data center.

If you desire a scalable and high-performance server that can handle a variety of workloads, the PowerEdge M640 is a top choice for you. From its build quality and design, the M640 is a performance workhorse. Its outside architecture features a blade server chassis that allows users to get up to 16 Intel scalable dual-socket compute nodes.

This means that you can easily scale up your workloads to handle HPC, Anything as a Service requirement (XaaS), and even cloud applications. As more businesses seek to switch to the cloud to handle critical business processes, the XaaS and cloud computing capabilities of the M640 offer your data center this much-needed capability.

Managing workload capacity

Both the Dell PowerEdge M630 and M640 servers are capable of managing flexible and scalable workloads. They offer flexible memory options and scalable nodes that make it possible for your data center to handle any surges in capacity.

The M630 is able to achieve this scalability primarily through its flexible memory options and bandwidth capability. The M630 offers Dell network adapters that are capable of offering speed, fabric, and vendor that is associated with data center workloads. With these options, you can tailor the server to handle precise workloads according to the specific bandwidth requirements.

Managing workload capacity on the PowerEdge M640 involves a combination of automation, architectural design, and processing power. The 16 Xeon Scalable nodes on the M640 are all housed in a single chassis that compacts power into a highly convenient design. In addition, its half-height construction makes it easy to fit into data centers with tight spaces and high computing requirements.

Automation capabilities

What sets the Dell PowerEdge servers apart is their ability to incorporate automation. The intelligent Dell OpenManage System provides the framework for remote access, virtual environments, and automation of routine tasks by administrators.

Starting with the Dell M630, its OpenManage framework features a systems management portfolio that can integrate with third-party solutions. It also allows for remote monitoring capabilities from a smartphone, tablet or other mobile devices.

And just when you thought automation couldn’t go any further, the PowerEdge M640 came along. It allows for a choice of collective or individual management of servers all via the Dell automation platform (Dell EMC Chassis Management Controller). The Dell EMC platform is compatible with OpenManage to achieve essential automation capabilities such as control from mobile applications or receipt of hardware alerts from anywhere and at anytime.

Wrap up

Ultimately, the choice between the Dell PowerEdge M630 and M640 is a consideration of performance capability, budget, workload management and automation. If you desire advanced memory capabilities, a simple design, and easy to customize interface/workloads, the M630 is the server for you. Another factor is price per performance, with the M630 being one generation older with a lower cost and great value. However, if you prefer a server with a flexible and scalable architecture, high density, and an emphasis on automation and data security – the PowerEdge M640 is the server of choice.
