Lenovo ThinkSystem 930-16i 8GB 12Gb/s SAS SAS9460-16i HH RAID Controller 01KN508

Lenovo ThinkSystem RAID 930-16i 8GB Flash PCIe 12Gb Adapter

The Lenovo Part Number 01KN508 (Feature Code: AUNB) designates the Lenovo ThinkSystem RAID 930-16i 8GB Flash PCIe 12Gb Adapter. Powered by the high-performance Broadcom SAS3516 dual-core RAID-on-Chip (RoC) processor, this enterprise-grade Half-Height/Half-Length (HH/HL) adapter is purpose-built to provide maximum internal drive expandability, ultra-high I/O throughput, and ironclad data protection for dense, multi-drive Lenovo ThinkSystem server platforms.

Equipped with a massive 8GB of onboard DDR4 cache and paired with a cache protection power module, it completely eliminates data choke points under demanding enterprise workloads like heavy database processing, massive virtualization arrays, and high-density storage applications.

Key Features & Capabilities

Massive Port Capacity (16-Port Native): Features four internal mini-SAS HD connectors (SFF-8643), allowing direct connection of up to 16 internal SAS or SATA drives without requiring an expander backplane.
Broadcom SAS3516 Dual-Core RoC: Offloads all compute-heavy array, XOR, and parity calculations onto the dedicated hardware controller, preserving host CPU cycles for critical applications.
8GB Cache with Flash-Backed Protection: Integrates a large 8GB DDR4-2133 memory cache to dramatically accelerate read/write execution patterns. In a power outage, the included supercapacitor-powered cache module instantly flushes cached data into non-volatile flash memory, eliminating the risk of data corruption.
Comprehensive Hardware RAID Architecture: Delivers full robust fault tolerance and performance scaling across a complete array matrix: Hardware RAID 0, 1, 5, 6, 10, 50, and 60.
Advanced Storage Technologies: Supports FastPath for maximum SSD performance, MegaRAID SafeStore software for self-encrypting drive (SED) key management, Online Capacity Expansion (OCE), and Online RAID Level Migration (RLM).
System Management Integration: Fully integrated with Lenovo’s XClarity Controller (XCC), allowing secure remote management, real-time inventory tracking, configuration setups, and firmware updates through a unified interface.
