FAQs

Q: What is the maximum memory capacity of the SR550?
A: The SR550 supports up to 768GB of DDR4 memory using 12x 64GB LRDIMMs (6 DIMMs per processor). It supports both RDIMMs and LRDIMMs at speeds up to 2933MHz with second-generation Xeon Scalable processors.

Q: Can I mix first and second generation Xeon Scalable processors?
A: No, mixing processor generations is not supported. The SR550 can be configured with either first-generation (Skylake) or second-generation (Cascade Lake) Intel Xeon Scalable processors, but both processors in a dual-socket configuration must be from the same generation.

Q: What storage configurations are available?
A: The SR550 offers multiple storage configurations: up to 16x 2.5-inch hot-swap drives for performance, up to 12x 3.5-inch hot-swap drives for capacity, or 8x 3.5-inch simple-swap drives. Additionally, it supports 2x M.2 drives for boot purposes, freeing up front bays for data storage.

Q: How many PCIe expansion slots does the SR550 provide?
A: The SR550 provides up to 6 PCIe 3.0 expansion slots when both processors are installed, plus a dedicated LOM slot and an optional ML2 mezzanine slot for 10GbE networking. Slot configuration depends on the riser cards selected. Note that an internal storage controller occupies slot 4.

Q: What management capabilities are built into the SR550?
A: The SR550 includes the Lenovo XClarity Controller for embedded systems management, providing IPMI 2.0 compliant functions, remote KVM, and virtual media support. It integrates with XClarity Administrator for centralized fleet management and includes XClarity Provisioning Manager for firmware updates and OS deployment.
