High-Speed DDR4 Memory
The SN550 V2 provides 16 DIMM slots when configured with two processors, with eight memory channels per processor.
It supports Lenovo TruDDR4 RDIMM and 3DS RDIMM memory, operating at speeds of up to 3200MHz. With supported 128GB 3DS RDIMMs, the system can accommodate up to 2TB of system memory.
The platform also supports Intel Optane Persistent Memory 200 Series, providing an additional option for memory-intensive workloads such as in-memory databases and dense virtualization.
Flexible Enterprise Storage
The SN550 V2 offers several internal storage configurations.
Depending on the installed backplane, it can support:
- Up to two 2.5-inch hot-swap drives
- SAS/SATA HDDs and SSDs
- NVMe/SATA SSDs
- Up to six EDSFF E1.S NVMe SSDs
- Up to two M.2 SATA/NVMe boot drives
The EDSFF configuration is particularly useful for applications requiring high-performance NVMe storage and increased I/O throughput.
NVMe and RAID Support
The SN550 V2 supports Intel VROC for NVMe and SATA RAID configurations, with additional Lenovo RAID adapters available.
Supported RAID hardware includes:
- ThinkSystem RAID 530-4i
- ThinkSystem RAID 930-4i
The M.2 solution can also support boot-drive configurations with optional RAID 0/1 functionality.
PCIe 4.0 Expansion
The SN550 V2 provides up to two PCIe 4.0 x16 mezzanine interfaces for networking and Fibre Channel adapters.
This enables high-bandwidth connectivity for:
- Ethernet adapters
- Fibre Channel
- High-performance storage
- Enterprise networking
- Data-center infrastructure
The PCIe 4.0 architecture provides increased bandwidth for supported expansion hardware.
High-Speed Networking
The SN550 V2 supports multiple high-speed networking configurations through its I/O expansion adapters.
Available options include:
- 10Gb Ethernet
- 25Gb Ethernet
- 50Gb Ethernet
- Fibre Channel
- FCoE
- iSCSI
Depending on the selected adapter, configurations can include 2-port or 4-port 10GbE, 4-port 25GbE, or 2-port 50GbE connectivity.
This makes the compute node well suited for virtualization clusters, high-speed storage networks, private cloud environments, and enterprise applications.
Lenovo XClarity Management
The SN550 V2 incorporates the Lenovo XClarity Controller (XCC) for hardware monitoring and management.
XClarity-based management provides capabilities such as:
- Hardware health monitoring
- System inventory
- Remote management
- Predictive failure alerts
- Diagnostics
- Firmware management
- Centralized infrastructure administration
Lenovo also supports XClarity Administrator and XClarity Integrator solutions for larger deployments.
Enterprise Security
The SN550 V2 includes enterprise security features designed for data-center environments.
These include:
- Integrated TPM
- Secure management
- Lenovo ThinkShield security
- NIST 800-131A compliance
- Hardware monitoring and predictive failure analysis
These features help organizations maintain secure and reliable infrastructure deployments.
Flex System Integration
Unlike a conventional standalone rack server, the SN550 V2 is a blade-style compute node designed for the Lenovo Flex System Enterprise Chassis.
The chassis provides centralized:
- Power
- Cooling
- Networking
- Management
- Compute-node infrastructure
Up to 14 SN550 V2 nodes can be installed in a compatible Flex Enterprise Chassis, enabling high-density data-center deployments.
