Lenovo ThinkSystem Servers

What is Lenovo ThinkSystem?

Lenovo ThinkSystem is physical servers - machines for server rooms where you run Windows Server, Linux, databases. It’s a competitor to HPE ProLiant and Dell PowerEdge.

Two types:

• SR (Server Rack) - flat, mounted in 19” rack, occupying 1U, 2U or 4U height
• ST (Server Tower) - towers, placed on the floor, like a large desktop computer

Current generation: V3 - latest Intel Xeon 4/5 generation or AMD EPYC Genoa processors, DDR5 memory, NVMe drives.

Example: A company has 5 ThinkSystem SR650 V3 servers with a hypervisor. They run 200 virtual machines - domain controllers, Exchange, SQL, application servers.

Which models to choose?

Model	Form	Processors	Max RAM	Typical use case
SR250 V3	1U rack	1x Xeon E	128 GB	Small branch, edge
SR630 V3	1U rack	2x Xeon/EPYC	4 TB	Web servers, compute
SR650 V3	2U rack	2x Xeon/EPYC	8 TB	Universal - most popular
SR850 V3	2U rack	4x Xeon	16 TB	SAP HANA, large databases
ST650 V3	Tower	2x Xeon/EPYC	8 TB	Company without server room

SR650 V3 - Lenovo’s “gold standard”. 2U, 2 processors, lots of RAM, lots of drives. Fits 80% of use cases.

ThinkShield - security

Lenovo ThinkShield is a set of hardware and firmware security features:

• Root of Trust - firmware verification at every boot
• Self-healing BIOS - automatic recovery when modifications detected
• Secure Boot - only signed code can run
• TPM 2.0 - hardware cryptographic module
• Encrypted drives - SED drive encryption

ThinkSystem vs competition

Feature	Lenovo ThinkSystem	HPE ProLiant	Dell PowerEdge
Management	XClarity	iLO	iDRAC
Security	ThinkShield	Silicon Root of Trust	Secured Component
4-socket	SR850 V3	DL560 Gen11	R960
AI/GPU	SR675 V3 (8x GPU)	ProLiant DL380a	XE9680

FAQ

What’s the difference between SR and ST? SR = Server Rack (for 19” rack). ST = Server Tower (tower, stands independently).

Intel or AMD? Intel Xeon - better for SAP, Oracle. AMD EPYC - more cores for lower price, ideal for virtualization.

How does XClarity compare to iLO? Similar features. XClarity Administrator (centralized management) is free for small fleets, iLO Advanced is paid.

Do HPE/Dell drives fit? No. Lenovo drives have their own firmware. You can use drives from other manufacturers, but you lose monitoring.

What warranty? 3 years NBD standard. Can be extended to 5 years with 24/7 and 4h response time.

Does Lenovo have GPU servers for AI? Yes. SR675 V3 accommodates 8x NVIDIA H100/A100 for AI/ML workloads.

What about delivery? Warehouses in Europe. Standard 2-3 weeks, CTO 4-6 weeks.

Does nFlo help with selection? Yes. We analyze your workloads and select optimal ThinkSystem configuration.
