Expand, pool and share memory between multiple servers to increase memory bandwidth and capacity while providing the option to reclaim stranded or under-utilized memory attached to a single server
Requirements and Challenges
Hyperscalerapplications require memory expansion, pooling and sharing solutions with scalable cloud infrastructure to optimizememory-intensive application performance or the utilization of memory across multiple servers to improve infrastructure total cost of ownership (TCO)
Large disaggregated topologieswith multiple cables introduce cable routing, serviceabilityand air flowchallenges
Passive PCIe DACs can only support ~3 meters for PCIe 5.x, limiting the number of hosts and CXL memory appliances that can be supported
Large topologieswith CXL devices require advanced cable and fleet management features essential managing data center infrastructure
Aries Smart Cable Module (SCM) Benefits
Purpose-built for demanding and low-latency disaggregated CXL memory infrastructure and delivers robust signal integrity and link stability over long distances
Improves cable routing and rack air flow with low power active electrical cables (AEC) using thin copper cables to scale disaggregated CXLmemory infrastructure within and across racks
Supports reliable PCIe 5.x/CXL 2.0 reach extension up to 7 meters to enable larger disaggregated CXL memory infrastructure in a multi-rack architecture
