Combining high-performance architecture with high-performance Xeon processors twice as many FSBs as before and each is 60% faster than before. Intel Extended Memory 64 Technology (EM64T) 64-bit extensions allow the Xeon processor to use large memory addressing when running with a 64-bit operating system. This in turn lets individual software processes directly access more than 4GB of RAM, which was the limit of 32- bit addressing. This can result in much higher performance for certain ki

Combining high-performance architecture with high-performance Xeon processors High-Speed Scalability Ports When more than one chassis is used, they are simply cabled together via one or more scalability cables. Up to three cables connected to low-latency, 10.24Gbps full-duplex ports (5.12Gbps in each direction), supported by up to 1GB of L4 cache, provide exceptional interchassis throughput (30.72Gbps aggregate). Because of this design, an x3950 M2 server has the incredible flex

Combining high-performance architecture with high-performance Xeon processors 3 times the maximum throughput of a 133MHz PCI-X adapter . (A x1 adapter offers throughput similar to a 66MHz PCI-X slot.) Because the SAS, ServeRAID-MR10k, dual Gigabit Ethernet, and systems management controllers are integrated onto the system board, the seven adapter slots are all available, which offers you a wide degree of latitude in expansion options. (Even though the HP DL580G5 has eleven total slots,

Combining high-performance architecture with high-performance Xeon processors front LED indicates an error condition, by pressing a button on the front of the server an LED panel will pop out and drop down for easy viewing without the need to open the server cover or remove the server from the rack. The light path diagnostics panel tells the servicer which component requires attention. In addition, many components have their own identifying LEDs. For example, each of the memory modules
