Description
The [Lenovo ThinkSystem ST558](#Lenovo ThinkSystem ST558) is an enterprise-grade 4U rackable tower server powered by up to two Intel® Xeon® Platinum processors (up to 20 cores each, 2.1 GHz base, 4.0 GHz turbo) for mission-critical workloads. With six memory channels per CPU and TruDDR4 support at up to 2933 MT/s, it accommodates up to 768 GB of RDIMM or 768 GB LRDIMM memory, plus optional Intel® Optane™ DC Persistent Memory for a combined capacity of up to 2 TB in App Direct mode Lenovo Press.
Storage configurability includes four hot-swap 3.5″ bays in the base model, expandable to eight 3.5″ or up to sixteen 2.5″ AnyBay bays supporting SAS, SATA, and direct-attach NVMe drives, delivering up to 154 TB of capacity and sub-millisecond I/O latency.
Two internal M.2 slots (RAID 1) handle OS boot without consuming drive bays, and Broadcom 12 Gbps RAID controllers with up to 4 GB cache support large-scale storage arrays Lenovo Press.
Lenovo’s XClarity suite—comprising embedded Controller, UEFI-based Provisioning Manager, and centralized Administrator—simplifies deployment, firmware updates, diagnostics, and power management, reducing provisioning time by up to 95 %
Comprehensive ThinkShield security features—including TPM 2.0, Secure Boot, Platform Firmware Resiliency (PFR), and chassis intrusion detection—protect data throughout the server’s lifecycle
