Dell PowerEdge | IBM 325 instruction

Outstanding 32/64-bit price/performance in a rack-dense 1U, 2-way server for HPC applications

3.Sell cost: Dramatically lower system price, plus the option of IDE or SCSI drives make the e325 a tremendous price/performer vs. the rx2600. Half the rack space required means fewer racks are required when large numbers of servers are involved, and less data center floor space.

Dell PowerEdge 1750

e325: The e325 with the Opteron processor can support a peak HyperTransport Tunnel bandwidth of 16.0GB per second, 375% better than that of Xeon.

PowerEdge 1750: The peak FSB bandwidth of Xeon is 4.26GBps in a system with a 533MHz FSB.

e325: Full-speed memory access (1.4GHz-2.0GHz, currently, depending on the model), due to the memory controller integrated into the Opteron processor.

PowerEdge 1750: Xeon accesses memory at the FSB speed (400MHz or 533MHz, currently).

e325: Supports 333MHz PC2700 DDR ECC memory with higher performance than PC2100 memory.

PowerEdge 1750: Supports only up to 266MHz PC2100 DDR ECC memory.

e325: The Opteron processor can support a peak aggregate memory bandwidth of 10.6GB per second in a 2-way configuration, up to 2.5X that of Xeon.

PowerEdge 1750: The peak aggregate memory bandwidth is 4.26GBps in a system with a 533MHz FSB.

e325: Supports up to 12GB17 of memory, 50% more than the Dell.

PowerEdge 1750: Supports up to 8GB of RAM.

e325: The e325, with the 64-bitOpteron processor, is capable of running either 32-bit or 64-bit software, or both at once.

PowerEdge 1750: Using the 32-bit Xeon processor, the PE 1750 is limited to only 32-bit software.

e325: Offers integrated RAID-1mirroring, standard.

PowerEdge 1750: An extra-costcard is required for RAID-1 support.

e325: The Opteron processor can support a peak aggregate I/O bandwidth of 12.8GB per second in a 2-way 2.0GHz configuration, 4 times that of Xeon.

PowerEdge 1750: The peak aggregate I/O bandwidth is 3.2GB per second.

e325: Provides integrated systems management functionality for remote management monitoring.

PowerEdge 1750: Requires an extra-costERA/O card for equivalent systems management capabilities.

e325: Models available with either low-cost IDE/ATA or high-performance Ultra320 SCSI drives.

PowerEdge 1750: Offers only SCSI models.

e325: The shallower depth of the e325 (65cm/25.6”) simplifies rack cable management and serviceability.

PowerEdge 1750: The PE 1750 at 68.6cm/27” is nearly 6% deeper than the e325.

e325: The e325 offers optional ACT cabling technology. This dramatically simplifies the cabling of rack-mounted servers and eliminates the need for up to hundreds of KVM cables per rack of 1U servers and associated PDUs and KVM switches. This can save the customer as much as thousands of dollars per rack over standard KVM cabling, as well as significant administration time. Also, the interconnection can be done without opening the chassis, and a server can be taken offline without changing the wiring.

PowerEdge 1750: Dell offers nothing equivalent to ACT. The administrator must install many KVM cables, switches and PDUs for a rack full of PE 1750 servers. Whenever a server is taken offline the remaining servers must be rewired—a time-consuming process.

1712GB capacity requires a 2-way system using 2GB DIMMs. A uniprocessor system is limited to 8GB of RAM.
