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 12GB
17
of memory, 50% more than the Dell.
PowerEdge 1750: Supports up to 8GB of RAM.
e325: The e325, with the 64-bit Opteron 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-1 mirroring, standard.
PowerEdge 1750: An extra-cost card 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-cost ERA/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.
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.
