Product Overview
The Lenovo 1U 6x2.5in SAS/SATA 4 AnyBay Backplane (PN: 4XH7A83856) is an enterprise-grade storage assembly engineered for high-performance server environments. It provides support for up to six 2.5-inch drives within a 1U chassis, making it a space-efficient solution for data centers and system builders. With support for SAS and SATA interfaces, this unit allows users to tailor their storage configuration to match performance and capacity requirements.
One of the key features of this backplane is its compatibility with Lenovo's AnyBay technology. AnyBay slots give administrators the flexibility to install either SAS or SATA drives—and even NVMe in some configurations—within the same drive bay. This allows for dynamic storage tiering and simplified upgrade paths over time. It is ideal for applications demanding both speed and versatility without increasing physical infrastructure complexity.
While detailed electrical and connectivity specifications are not provided, the component is categorized under Lenovo's computer component family, indicating its preferred use in professional server hardware builds. Its support for hybrid drive connectivity, dense design, and manufacturer backing underscore its role as a reliable data center accessory.
