Figure 1. Lenovo ThinkServer RD550

Lenovo’s distinctive AnyFabric design provides an array of powerful HBA, CNA and 1 Gbps and 10 Gbps Ethernet choices to address growing network bandwidth requirements without the use of a PCIe slot.

This storage-rich server provides up to 52 TB of storage capacity and features an Industry-unique Lenovo AnyBay design that allows multiple storage types in the same drive bay. M.2 and SD card options are available, which enable flexible boot drive choices.

The RD550 provides Lenovo AnyRAID technology, a midplane RAID adapter design that connects directly to the drive backplane without using a PCIe slot. A comprehensive portfolio of AnyRAID controllers is available for various applications, which include software, IO Controller, and RAID on Chip-based controllers.

The RD550 delivers impressive compute power per watt, featuring 80 PLUS Titanium and Platinum redundant power supplies. This server is designed to meet ASHRAE A4 standards, which enable customers to lower energy costs.

The ThinkServer RD550 offers the following key features:

• Extremely versatile storage

Innovation is built in to the ThinkServer RD550. A cleverly engineered design allows more storage density and I/O connectivity than ever before — giving you the performance and capacity of a 2U system in a 1U form factor. By creating smaller drive trays and a slightly larger chassis within the same 1U space, the RD550 offers a total of up to 12 front drive bays, which can be used for data storage or better performance. Two additional enterprise-class M.2 SSDs are available as an option for secure booting, as well as SD card options for hypervisor booting. Plus, for ultimate performance, the industry-unique Lenovo AnyBay design allows multiple storage types in the same drive bay, including front-accessible PCIe SSD.

• Highly flexible I/O

In the past, 1U servers were constrained by their size and did not have as many I/O slots as larger servers. With the new RD550, networking configurations that traditionally required a larger server can now fit into a 1U form factor. Leveraging the unique Lenovo AnyFabric design, the RD550 can house up to eight 10 Gb Ethernet ports — without taking up any of the available PCIe slots. If you include network adapters in the available slots, the RD550 can support an incredible amount of network bandwidth in a single 1U server. There’s even an option for four 10 Gb Ethernet ports with two 16 Gb Fibre Channel ports at the same time, without using any of the PCIe slots — an industry first.

• Extra-reliable performance

Data center cooling costs can be greater than the cost of powering the IT equipment itself. One way to reduce these cooling costs is by operating the data center at a higher temperature. With a dynamic environmental design, the RD550 can run continuously at 45 degrees Celsius — with no impact on reliability. In fact, the system has been carefully architected and tested to support long-term reliability. The RD550 is also perfect for organizations that install servers in less strictly controlled environments. Other high-reliability features include error correcting code (ECC) memory, hot-swap hard-disk drive and SSD capability, and hot-swap and redundant power and cooling.

The RD550 supports new tools for easy configuration, deployment and power-planning. ThinkServer System Manager enables you to remotely and securely manage your servers via web browser. With the optional ThinkServer System Manager Premium, you can enhance your management functionality with remote keyboard, video, and mouse (KVM) access; and decrease your power usage with an included license for ThinkServer Energy Manager.

The RD550 supports up to two processors. The following table lists the specifications of the processors that are available for the RD550.

For RD550 server models that come standard with one processor, the second processor can be ordered, if required (see the following table for ordering information). The second processor must be of the same model as the first processor. The part number for the second processor includes a CPU, a heatsink, and two system fans.

Lenovo DDR4 memory is compatibility tested and tuned for optimal ThinkServer performance and throughput. From a service and support standpoint, Lenovo memory automatically assumes the system warranty, and Lenovo provides service and support worldwide.

The RD550 server supports up to 12 DIMMs when one processor is installed and up to 24 DIMMs when two processors are installed. Each processor has four memory channels and there are three DIMMs per channel. The RD550 supports up to 768 GB of memory at up to 1866 MHz when fully populated. The actual memory speed in the system is determined as the lowest of the memory speed that is supported by the specific CPU or the maximum operating speeds for the memory configuration that is based on the number of DIMMs per channel.

ThinkServer engineering tested and validated system designs that support memory speeds beyond Intel’s original plan, which provides benefits for workloads that require memory speed and density. Lenovo ThinkServer memory is fully supported up to the rated speeds that are shown in the following table.

The following rules apply when the memory configuration is selected:

• The server supports RDIMMs and LRDIMMs.
• Mixing different types of memory (RDIMMs and LRDIMMs) is not supported.
• DIMM capacities and rank can be mixed.

• ECC
• Lockstep (SDDC x4/x8)
• Memory mirroring
• Memory sparing
• Patrol scrubbing
• Demand scrubbing

If lockstep or memory mirroring is used, RDIMMs must be installed in pairs (a minimum of one pair per each processor), and both RDIMMs in a pair must be identical in type, size, and rank.

If memory sparing is used, one rank of a DIMM in each populated channel is reserved as spare memory; therefore, single-rank DIMMs cannot be used. DIMMs in a pair must be identical in type, size, and rank.

Lockstep, memory mirroring, and memory sparing modes are mutually exclusive. Only one operational memory mode can be enabled on the server, and it is a system-wide setting.

The following table lists available memory options for the RD550.

The RD550 server supports the following internal storage configurations:

• Server models without any drive bays that can be upgraded to 4x 3.5-inch SAS/SATA hot-swap drive bays
