Use Case
Structera X 2504 is the capacity lever for servers whose DDR slots are full but whose workload footprint keeps growing: it attaches over CXL 2.0 and adds more than 6TB of DDR5 capacity at up to 200 GB/s, with hardware LZ4 compression inline so a given physical DIMM serves more logical data. It is designed alongside hyperscalers and is in volume deployment for AI inference, DLRM and in-memory databases.
