Intel Xeon E-2400 processors/Intel Xeon 6300 processors
Designed for small- to medium-sized businesses (SMBs) and cloud-service providers, offering robust and secure solutions. These processors support up to eight cores and 16 threads, with a maximum frequency of 5.6 GHz and a 95 W TDP, ensuring rapid data processing and application responsiveness. They support up to 128 GB of DDR5 4400 MT/s memory (Intel Xeon E-2400) or up to 4800 MT/s memory (Intel Xeon 6300) and PCIe 5.0 interfaces, providing server-grade 24/7 reliability for business-critical services and customer data, and cost-effective performance for entry-level bare-metal cloud services.
PCIe 5.0 ready
Faster storage, graphics and networking capabilities PCI Express® (PCIe®) 5.0 delivers 32GT/s bandwidth, which is twice the speed of PCIe 4.0, and offers lower power consumption, better land scalability and backwards compatibility. ASUS servers are PCIe 5.0 ready with scalability design to satisfy the increasing workloads for modern data center.
Redundant Platinum PSU support
RS300-E12-RS4 supports redundant 450W 80 PLUS Platinum power supplies, which are 96%+ efficient, directly reducing operating costs and capital expenses. The 1+1 power-supply design allows the server to keep working even if one power supply requires maintenance, enabling uninterrupted operation.
