HP Server tc2120T01 Desktop Server (2.66 GHz Pentium 4, 256MB RAM, 36.4GB hard drive, 48x CD-ROM) (3335874-001 )

HP's affordable tc2120 desktop server makes running a small network for your business a hassle-free breeze. It boasts Error Checking and Correcting (ECC) memory, fully functional gigabit networking, and 64-bit PCI technology. And it's specifically designed for and rigorously tested with server operating systems in demanding server configurations. The ergonomic chassis makes addition of memory, drives, and devices quick and easy. This model configuration of the tc2120 features the following specifications: Processor: 1 Intel Pentium 4 2.66 GHz (standard) Cache Memory: Integrated 512-KB Level 2 cache Memory: 256 MB (Standard) to 4 GB (Maximum) PC2100 DDR SDRAM DIMM Memory running at 266 MHz, with Advanced ECC capabilities Network Controller: NC7760 PCI Gigabit NIC (embedded) 10/100/1000 WOL (Wake on LAN) Storage Controller: HP Single Channel Ultra3 SCSI Adapter Hard Drive: 36.4 GB Ultra320 SCSI 10,000 rpm 1-inch drive Internal Storage: 109.2 GB maximum Optical Drive: 48x IDE (ATAPI) CD-ROM Drive With an industry leading five 64-bit PCI slots, the tc2120 provides more than enough performance and expandability for additional NICs, RAID cards, or other devices. This 64-bit PCI support is critical for overall server performance. In the tc2120, the PCI bus hosts all networking devices and PCI cards such as gigabit NICs or SCSI disk controllers. Moving from a 32-bit (as is still used in desktops) to a 64-bit bus doubles the amount of data transferred for a given unit of time. To achieve true gigabit NIC support (send a{section} receive), a 64-bit PCI bus is required. When running multiple tasks in parallel, such as communicating with the network and writing to the SCSI drives, the higher bandwidth 64-bit bus reduces bottlenecking that can impact system performance. Additionally 64-bit PCI support increases the number of supported devices (such as PCI-X cards or RAID controllers not able to run on 32-bit buses). The chassis features one-finger removal of the side panel to access all internal components and a color-coded g
