The SR250 V3 server is a compact, cost-effective, single-processor 1U rack server that has been optimized to provide enterprise-class features to small-to-medium-sized businesses, retail stores, or distributed enterprises.

Scalability and performance

The SR250 V3 offers the following features to boost performance, improve scalability, and reduce costs:

• Improved single-socket processor performance:
  • Intel Xeon E-2400 Series processors ("Raptor Lake") up to to 8 cores and core speeds up to 3.5 GHz
  • Intel Pentium G7400 and G7400T processors ("Alder Lake") with 2 cores and core speeds up to 3.7 GHz
• Up to four 4800 MHz DDR5 ECC UDIMMs provide speed and capacity of up to 128 GB
• Offers flexible and scalable internal storage in a 1U rack form factor with up to 10x 2.5-inch drives for performance-optimized configurations or up to 4x 3.5-inch drives for capacity-optimized configurations
• Up to three PCIe slots for I/O expansion, riser dependent, one of which has the new PCIe Gen5 interface to maximize I/O performance
• 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 Lenovo and Broadcom provide 12 Gb SAS connectivity to the drive backplanes
• Supports two M.2 drives for OS boot support with VROC RAID or hardware RAID redundancy
• The server has two integrated Gigabit Ethernet ports
• Support for a NVIDIA GPU for enhanced workload performance

Availability and serviceability

The SR250 V3 server provides many features to simplify serviceability and increase system uptime:

• Designed to run 24 hours a day, 7 days a week
• The SR250 V3 supports UDIMM memory with ECC protection which provides error correction not available in PC-class "servers" that use parity memory. Avoiding system crashes (and data loss) due to soft memory errors means greater system uptime.
• Provides easy access to upgrades and serviceable parts (such as memory DIMMs and adapter cards) with tool-less cover removal.
• Much like hot-swap drives, simple-swap drives are mounted on an easy-to-remove tray and work with the same RAID options. Simple-swap require a system power-down before adding or replacing, however simple-swap drives are less expensive than hot-swap drives.
• Offers data protection and greater system uptime with a choice of affordable onboard SATA RAID or advanced hardware RAID redundancy, along with hot-swap drives (select models).
• The server supports hot-swap power supplies; with two installed, they form a redundant pair to provide availability for business-critical applications.
• The built-in Lenovo XClarity Controller 2 (XCC2) continuously monitors system parameters, triggers alerts, and performs recovery actions in case of failures to minimize downtime.
• Allows preventive actions in advance of possible failure, thereby increasing server uptime and application availability with Proactive Platform Alerts (including PFA and SMART alerts) for memory, internal storage (SAS/SATA HDDs and SSDs, NVMe SSDs, M.2 SSDs), RAID controllers, and server ambient and sub-component temperatures.
• Provides quick access to system status, firmware, network, health, and alerts information via Virtual Operator Panel from the XClarity Mobile App running on the Android or iOS mobile device that is connected to the front USB port with XCC2 access.
• Built-in diagnostics in UEFI, using Lenovo XClarity Provisioning Manager, speed up troubleshooting tasks to reduce service time.
• Lenovo XClarity Provisioning Manager supports diagnostics and can save service data to a USB key drive or remote CIFS share folder for troubleshooting and reduce service time.
• Support for the XClarity Administrator Mobile app running on a supported smartphone and connected to the server through the service-enabled USB port, enables additional local systems management functions.
• Auto restart in the event of a momentary loss of AC power (based on power policy setting in the XClarity Controller service processor) (hot-swap power supplies only)
• One-year or three-year customer-replaceable unit (CRU) and onsite limited warranty with next business day response. Optional service upgrades are available.
