The CS58 NetBrain server is based on an 800MHz version of the Crusoe processor, which represents a step up from the 600MHz chip used in the last model. Other areas have also been improved with the top-of-the-range model featuring 640Mbytes of memory and a pair of 80Gbyte RAID hard disk drives.
Additional features include a 24X CD-ROM drive, two PCI card slots, Fast Ethernet port and two USB ports. Some models also feature a PC Card slot, internal speaker, second Fast Ethernet port and uninterruptible power supply (UPS).
The extra features mean the CS58 uses more power. Peak energy consumption is estimated at around 43 watts, which is roughly double that of the CS56. However, the energy-efficient Crusoe processor means it is still lower than that of most servers based on Intel and Advanced Micro Devices (AMD) processors. Like the previous version, the CS58 will run quietly as the Crusoe processor requires no fan.
Prices range from ¥100,000 (£527) to ¥178,000 and NEC said it has no immediate plans to put the server on sale overseas.
