Key features

The ThinkSystem ST550 is a high-performance dual-socket tower server based on the new Intel Xeon
Processor Scalable Family, supporting a wide range of processors to suit a wide range of budgets and
application requirements.
Scalability and performance
The ST550 offers the following features to boost performance, improve scalability, and reduce costs:
Improves productivity by offering superior system performance with up to two processors, each
with up to 20 cores, and core speeds up to 3.6 GHz.
Hyper-Threading Technology to maximize the concurrent execution of multithreaded applications,
available with most processors.
Intelligent and adaptive system performance with energy-efficient Intel Turbo Boost Technology,
available with most processors, allows CPU cores to run at maximum speeds during peak
workloads by temporarily going beyond processor thermal design power (TDP).
Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operating
system vendors to better use the hardware for virtualization workloads.
Intel Advanced Vector Extensions 512 (AVX-512) enable acceleration of enterprise-class workloads,
including databases and enterprise resource planning (ERP).
Each processor has six memory channels with memory speeds of up to 2666 MHz to help maximize
system performance.
Up to 768 GB of memory capacity with 64 GB load-reduced DIMMs (LRDIMMs)
The 12 Gbps 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 storage configurations support either 2.5-inch or 3.5-inch hot-swap drive bays or a
combination of the two (hybrid configuration). Configurations with 3-5-inch simple-swap drive bays
are also available.
Up to 16x 2.5-inch drive bays with two 5.25-inch media drive bays available
Up to 20x 2.5-inch drive bays with the media bays converted to 4x 2.5-inch drive bays
Up to 8x 3.5-inch drive bays with two 5.25-inch media drive bays available
Up to 8x 3.5-inch + 4x 2.5-inch drive bays with the media bay conversion
Up to 8x 3.5-inch simple-swap drive bays
3.5-inch drive bays support SAS and SATA HDDs and SSDs. 2.5-inch drive bays support SAS and
SATA HDDs and SSDs, as well as NVMe drives.
Support for up to four NVMe PCIe SSDs in a 2.5-inch form factor maximizes drive I/O performance,
in terms of throughput, bandwidth, and latency.
Scalable internal storage configurations provide for up to 95.4 TB of storage capacity using 8x 10TB
3.5-inch HDDs and 4x 3.84TB 2.5-inch SSDs.
The use of solid-state drives (SSDs) instead of, or along with, traditional hard disk drives (HDDs) can
significantly improve I/O performance. An SSD can support up to 100 times more I/O operations per
second (IOPS) than a typical HDD.
New high-speed RAID controllers from Broadcom provide 12 Gb SAS connectivity to the drive
backplanes. A variety of RAID adapters are available, with cache up to 4 TB and support for 20
drives on a single controller.
Supports a new Lenovo patented-design M.2 adapter for convenient operating system boot
functions. Available M.2 adapters support either one M.2 drive or two M.2 drives in a RAID 1
configuration for greater boot drive performance and reliability.
The server has two integrated Gigabit Ethernet ports.
