Electrical Facilities

Depending on whether data availability is critical to your application or not, when you configured your system, you chose either an uninterruptible power source or a power distribution unit to supply rack components with AC power. The AC supply lines required by each of these devices is specified in the following paragraphs.

Uninterruptible Power Source (UPS)

If you have purchased one or more UPSs to supply AC power to your system and your system is located in North America, each UPS requires a 3-wire

30-Amp single-phase 120 Volt receptacle within six feet of the rear of the system rack. The UPS power cord comes equipped with a NEMA L5-30P power connector.

If your system is located in Europe, it requires a 240 Volt receptacle. The UPS power cord comes equipped with an IEC-320-C20 power connector.

Power Distribution Unit (PDU)

If you have purchased one or more PDUs, each PDU requires a 3-wire 30-Amp single-phase 120 Volt (240 Volt in Europe) receptacle within 10 feet of the rear of the system rack. The UPS power cord comes equipped with a NEMA L5-30P power connector (US models).

The servers in this series support Intel's latest Xeon processors, which offer powerful performance and energy efficiency, making them ideal for compute-heavy applications.

In terms of memory, the NEC EXPRESS800 series supports large capacities and high-speed DDR4 RAM, ensuring that applications run smoothly even under heavy loads. This is particularly important for virtualization and large-scale data processing tasks that require rapid data access. The system also implements advanced error-correcting code (ECC) technology, which enhances data integrity and system reliability.

Storage is another key characteristic of the EXPRESS800 series. The servers feature a variety of storage options, including traditional HDDs and high-speed SSDs, allowing for optimized performance and flexibility in storage management. NEC’s implementation of high-performance RAID technology ensures data redundancy and enhances data access speeds, which is crucial for mission-critical applications.

Security features are also paramount in the design of the EXPRESS800 series. NEC incorporates Trusted Platform Module (TPM) integration, providing hardware-level security against unauthorized access. Additionally, the systems are designed to facilitate secure remote management, enabling IT administrators to monitor and control server performance from virtually anywhere.

Another notable technology integrated within the EXPRESS800 servers is virtualization support. With robust hypervisor capabilities, these servers permit efficient resource utilization, allowing multiple virtual machines to run concurrently without compromising performance. This is complemented by NEC’s advanced management software, which provides comprehensive tools for system monitoring and optimization.

Power efficiency is a critical consideration, and the NEC EXPRESS800 series is built with energy-efficient components and smart power management features. By optimizing power consumption, businesses can reduce their operational costs while minimizing their environmental impact.

In summary, the NEC EXPRESS800 series combines advanced technology, versatility, and high performance in a server solution that meets the diverse needs of modern enterprises. Its modular design, efficient processing power, superior memory capabilities, and robust security features position it as an ideal choice for organizations seeking reliable and scalable server solutions.
