B. DIMMs Supported

The DDR3 memory interface consists of three channels, with up to two RDIMMs or UDIMMs per chan- nel for single-/dual-rank and up to two RDIMMs per channel for quad rank. The interface uses 2GB, 4GB, or 8GB RDIMMs. 1GB or 2GB UDIMMs are also supported. The memory mode is dependent on how the memory is populated in the system:

Three channels per CPU populated identically.

In a dual-processor configuration, the memory configurations for each processor must be identical

•Typically, the system will be set to run in Memory Optimized (Independent Channel) mode in this configuration. This mode offers the most DIMM population flexibility and system memory capacity, but offers the least number of RAS (reliability, availability, service) features.

•Memory modules are installed in numeric order for the sockets beginning with A1 or B1

•All three channels must be populated identically.

•The first two channels per CPU populated identically with the third channel unused

•Typically, two channels operate in Advanced ECC (Lockstep) mode with each other by having the cache line split across both channels. This mode provides improved RAS features (SDDC support for x8-based memory).

•For Memory Mirroring, two channels operate as mirrors of each other — writes go to both channels and reads alternate between the two channels.

•For Memory Mirroring or Advanced ECC Mode, the three sockets furthest from the processor are unused and memory modules are installed beginning with socket A2 or B2 and proceeding in the following order: A2, A3, A5, and A6

•One channel per CPU populated

•This is a simple Memory Optimized mode. Mirroring is not supported.

The PowerEdge R610 memory interface supports memory demand and patrol scrubbing, single-bit correction and multi-bit error detection. Correction of a x4 or x8 device failure is also possible with SDDC in the Advanced ECC mode. Additionally, correction of a x4 device failure is possible in the Memory Optimized mode.

•If DIMMs of different speeds are mixed, all channels will operate at the fastest common frequency.

•RDIMMs and UDIMMs cannot be mixed.

•If memory mirroring is enabled, identical DIMMs must be installed in the same slots across both channels. The third channel of each processor is unavailable for memory mirroring.

•The first DIMM slot in each channel is color-coded with white ejection tabs for ease of installation.

R610 specifications

The Dell PowerEdge R610 is a 1U rack server that combines outstanding performance with advanced management features, making it ideal for enterprises and small to medium-sized businesses. Introduced as part of Dell’s 11th generation of servers, the R610 is designed to meet demanding workloads while optimizing energy consumption.

One of the main features of the R610 is its dual-socket capability, supporting up to two Intel Xeon 5500 or 5600 series processors. This allows significant scaling of compute power, enabling users to run multiple applications concurrently without a hitch. The server supports up to 192 GB of DDR3 memory with 18 DIMM slots, providing ample bandwidth for memory-intensive workloads.

Storage flexibility is another hallmark of the R610. It offers a choice of up to six 2.5-inch SAS, SATA, or solid-state drives, which allows for impressive storage capacities and the option for RAID configurations. This ensures data integrity and high availability, catering to the needs of various applications from databases to virtual environments.

The Dell R610 introduces advanced virtualization technologies, with support for VMware and Microsoft Hyper-V, making it an excellent choice for virtualized environments. With the option to deploy multiple virtual machines on a single physical server, organizations can maximize resource allocation and reduce costs.

In terms of management, the R610 is equipped with the Integrated Dell Remote Access Controller (iDRAC) which provides out-of-band management capabilities. This feature allows administrators to monitor system health, perform firmware updates, and manage hardware without the need for physical access to the server.

Energy efficiency is a notable characteristic of the R610, complying with Energy Star requirements. It utilizes lower power consumption components and features such as dynamic power management, which adjusts the power usage based on real-time workload demand. This characteristic contributes to lower operational costs and a reduced environmental footprint.

The Dell PowerEdge R610 excels in providing an optimal balance of performance, manageability, and energy efficiency, making it a powerful tool for IT environments that demand reliability and scalability. Its robust feature set and support for virtualization technologies position it as a favorable choice for businesses looking to enhance their IT infrastructure efficiently.
