Key features
The ThinkServer RD550 offers performance and capacity of a 2U system in a 1U rack form factor. Energy-
smart design with powerful high-performance processors, a large capacity of high-performing DDR4
memory, and flexible storage and networking configurations are ideal for business-critical applications and
cloud deployments.
Scalability and performance
The ThinkServer RD550 offers numerous features to boost performance, improve scalability, and reduce
costs:
Improves productivity by offering superior system performance with the Intel Xeon processor E5-
2600 v4 product family with up to 22-core processors, up to 55 MB of L3 cache, and up to 9.6 GT/s
QPI interconnect links.
Support for up to two processors, 44 cores, and 88 threads allows to maximize the
concurrent execution of multithreaded applications.
Intelligent and adaptive system performance with energy efficient Intel Turbo Boost
Technology allows CPU cores to run at maximum speeds during peak workloads by
temporarily going beyond processor thermal design power (TDP).
Intel Hyper-Threading Technology boosts performance for multithreaded applications by
enabling simultaneous multithreading within each processor core, up to two threads per
core.
Intel Virtualization Technology integrates hardware-level virtualization hooks that allow
operating system vendors to better utilize the hardware for virtualization workloads.
Up to 2400 MHz memory speeds with two DIMMs per channel running at 2400 MHz to help
maximize system performance.
Up to 1.5 TB of memory capacity with 64 GB Load Reduced DIMMs (LRDIMMs).
12 Gbps serial-attached SCSI (SAS) internal storage connectivity doubles the data transfer rate
compared to 6 Gb SAS solutions to maximize performance of storage I/O-intensive applications.
Flexible and scalable internal storage configurations that feature an industry-unique Lenovo
AnyBay™ design, which allows a choice of SAS, SATA or PCIe interface drives in the same
bay, provide up to 44 TB of storage capacity in a 1U rack form factor.
The use of SSDs instead of or along with traditional spinning HDDs can significantly improve I/O
performance. An SSD can support a significantly higher number of I/O operations per second (IOPS)
than a typical HDD.
The RD550 server offers up to three PCI Express (PCIe) 3.0 I/O expansion slots and up to two
AnyFabric slots for a total of five I/O slots in a dense 1U rack 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.
The RD550 provides Lenovo AnyRAID® technology, which is a midplane RAID adapter that
connects directly to the drive backplane without using a PCIe slot.
With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon
processor E5-2600 v4 product family. This helps to dramatically reduce I/O latency and increase
overall system performance.
