What is the Dell R740xd2?

The Dell R740xd2 organizes vast amounts of disk space in a compact package, made possible by its innovative design changes. This server effectively addresses the growing volume of information and offers flexible scalability. With the R740xd2, response times can be minimized by positioning compute resources near storage resources. Consequently, system stability is maintained even with the increase in resource-intensive tasks, such as streaming multimedia or email transmission.

Comparison of Dell PowerEdge R740 and R740xd2 servers

The Dell EMC PowerEdge R740 and R740xd2 are both 2U rackmount servers designed primarily to handle complex workloads with scalable memory, I/O bandwidth, and networking options. 

The primary distinction between the Dell PowerEdge R740 and R740xd2 is disk density. The R740xd2 offers 24 x 3.5" drives with an additional 16x3.5" + 10x2.5" option to expand storage in response to increasing workloads. With the R740xd2, there's often no need for external storage subsystems as its total storage capacity exceeds 200 TB, in contrast to the R740's maximum of 80 TB.

Comparison of other datasheet of Dell PowerEdge R740 and Dell PowerEdge R740xd2 is shown in the table:

Dell R740xd2 main advantages

The R740xd2 server offers significant potential for expanding disk capacities within a 2U form factor case, allowing for more efficient processing of data packets and full utilization of storage resources.

The scale-up and scale-out capabilities of the R740xd2 are notable, supporting up to 24 3.5" (364 TB) drives in a 2U rack server and up to 520 3.5" (7.2 PB) drives in a 42U rack server. Additionally, the server can be configured in various combinations of SFF SSDs and LFF HDDs to optimize efficiency and cost, while automatically distributing data across tiers.

Consequently, this server is ideally suited for:

  • Analyzing large volumes of data;
  • Deploying software-defined storage;
  • Supporting Big Data systems. 

The versatility of the R740xd2 is particularly valuable for cloud service and hosting providers offering colocation services.

Dell R740xd2 spec sheet and additional benefits:

  • Integration of OpenManage with VMware vCenter and Microsoft System Center (SC) consoles simplifies server management processes.
  • User-friendly interface displays statuses and alerts for all connected physical and virtual devices.
  • Supports up to 16 DIMMs, enhancing network connections and eliminating bottlenecks.
  • Easily expandable with five PCIe slots.
  • Comprehensive lifecycle management includes predictive diagnostics, firmware updates, and automated problem resolution.
  • Rapid deployment of configurations across multiple physical servers, tailored to unique workload requirements, via OpenManage Enterprise.
  • Streamlined data center IT operations using Dell EMC OpenManage™ tools and solutions.
  • Full automation and federated server and back-end storage management across the entire infrastructure with Dell EMC iDRAC9.

Continual server operation ensured 24 validated front-mount, hot-swappable drives. The R740xd2's security is fortified at the architectural level with embedded security tools and signed authenticated firmware.
