Lenovo ThinkSystem DE6600H
The ThinkSystem DE6600H is Lenovo's flagship high-performance hybrid storage array, designed for maximum throughput, low microsecond latency, and petabyte-scale capacity. Built on dual controllers offering 128GB total system cache memory, the system handles heavy transactional databases, real-time analytics, machine learning pipelines, and dense backup pools. It features hardware-accelerated NVMe over Fabrics connectivity (including 100Gb RoCE and InfiniBand) alongside 32Gb Fibre Channel and 25Gb iSCSI. When buying second-hand units, administrators should ensure cache modules match, check all internal fan modules, and verify that optical transceivers are authentic Lenovo or NetApp certified optics.
