ecs.d3c.7xlarge by Alibaba Cloud

A high-capacity storage instance featuring dedicated processing cores and massive local HDD capacity for large-scale data workloads.

Alibaba Cloud ecs.d3c.7xlarge is a storage-focused server instance built on the x86_64 architecture. It features a dedicated Intel Xeon 8369B processor operating at 2.9 GHz, delivering 28 physical cores and 28 vCPUs with no hyperthreading. The system is configured with 112.0 GB of RAM, providing a balanced 4.0 GB per core ratio. Its primary differentiator is the inclusion of 27,487 GB of local HDD storage, paired with a baseline network bandwidth of 16 Gbps. Operating under a KVM hypervisor, this instance is designed for storage-intensive applications. The massive local HDD capacity makes it highly cost-efficient for large-scale data storage, though it trades off the high IOPS of solid-state drives. It is best suited for distributed file systems, big data processing, and data warehousing workloads.
