GIGA G494-ZB4: High-Performance 4U Dual-Socket Server

The G494-ZB4 is a flagship 4U server designed for extreme compute density, AI training, and large-scale virtualization. Featuring dual AMD EPYC 9004 “Genoa” processors (Zen 4), this powerhouse supports up to 192 cores/384 threads and 6TB of DDR5 memory across 24 DIMM slots. Its 24x 2.5″ hot-swappable bays (supporting SAS/SATA/NVMe) deliver exceptional storage performance, while 8x PCIe 5.0 slots enable massive expansion for GPUs, accelerators, or NVMe storage. With dual 2000W Platinum PSUs and support for up to 4x full-height GPUs, the ZB4 excels in HPC, machine learning, and mission-critical enterprise workloads where uncompromising performance is required.

✔ Best For: AI/ML training, hyperscale virtualization, high-frequency trading, and large in-memory databases.

GIGA G494-ZB1: Hybrid Storage Enterprise Server

The G494-ZB1 offers versatile 4U storage and compute with a dual-socket AMD EPYC 9004 configuration. It balances high-capacity storage (12x 3.5″ + 2x 2.5″ bays) with 6TB DDR5 memory and 6x PCIe 5.0 slots, making it ideal for mixed workloads. The hybrid drive support allows for high-capacity HDDs + fast NVMe caching, while dual 1600W Gold PSUs ensure efficient power delivery. With support for up to 3x GPUs, this server is optimized for enterprise databases, software-defined storage (SDS), and private cloud deployments.

✔ Best For: Virtualized storage, big data analytics, and enterprise applications requiring a balance of capacity and performance.

GIGA G494-ZB0: Entry-Level 4U Storage Server

The G494-ZB0 is a cost-effective single-socket 4U server designed for SMBs and general-purpose workloads. Powered by a single AMD EPYC 9004 CPU, it supports up to 3TB DDR5 memory via 12 DIMM slots and 12x 3.5″ hot-swappable bays (SAS/SATA). While it has fewer PCIe lanes (4x PCIe 5.0 slots), it remains capable of handling 2x GPUs for light acceleration tasks. The single 1600W PSU (optional redundancy) makes it budget-friendly while still delivering enterprise-grade reliability.

✔ Best For: Backup servers, file storage, light virtualization, and edge computing deployments.
