posted a floating-point score that was 41% better than that of the Xeon-based HP DL360 G3

 

 

server, and at a slightly lower cost. The same e325 score was 63% of that posted by the Itanium

 

 

2-based HP rx2600 server, but at one-seventh the cost!

 

 

In short: Compared to the x335, the e325 is faster (faster processor for integer operations, faster

 

 

DDR memory), has greater memory capacity, and it offers the ability to run both 32-bit and

 

 

64-bitapplications concurrently. When running a 64-bit operating system, the e325 breaks

 

 

through the “4GB barrier” for memory addressing imposed by 32-bit processors.

 

 

 

 

 

 

What’s New? (Compared to the x335)

Key Features

 

 

y AMD Opteron processors with HyperTransport technology, integrated memory controller and

 

 

1MB of L2 processor cache

 

 

y PC2700 333MHz DDR Chipkill ECC memory (vs. PC2100 266MHz DDR Chipkill ECC

 

 

memory for the x335)

 

 

y 12GB memory capacity (vs. 8MB for the x335)

 

 

y Four USB 1.1 ports (2 front, 2 rear)

 

 

y Optional USB floppy drive

 

 

 

 

 

 

 

High-Performance Opteron Processors

 

 

The e325 offers a choice of processors:

 

 

y AMD Opteron 240, 242 and 246

 

 

The integrated memory controller and 1MB of L2 cache run at the full processor clock rate, not the

 

 

stepped down rate of the front-side bus (FSB) used in Intel processors. Because of this, the

 

 

Opteron 246’s Hyper Transport Tunnel offers peak throughput of 16.0GB per second vs. only

 

 

6.4GBps for the (1.5GHz) Itanium’s front-side bus (FSB) — up to 250% faster than Itanium 2, and

 

 

a maximum of 4.26GBps for the (3.06GHz) Xeon’s FSB (up to 375% faster than Xeon). Similarly,

 

 

the maximum aggregate peak memory throughput of the Opteron in a 2-way configuration is

 

 

10.6GBps, or up to 250% higher throughput than the peak rate of 4.26GBps provided by the

 

 

533MHz FSB of the Intel Xeon processor used in the x335, and up to 24% more than the 8.5GBps

 

 

of the Itanium 2. I/O performance is equally strong, with the Opteron supporting a peak I/O

 

 

bandwidth of 12.8GBps, or up to 50% more than the Itanium’s 6.4GBps maximum, and up to 400%

 

 

of the 3.2GBps of the Xeon.

 

 

The e325 ships with one processor, upgradable to two.

 

 

 

 

 

 

 

 

DDR Chipkill ECC Memory

 

 

The e325 supports up to 12GB4 of memory in six DIMM sockets. It uses registered PC2700

 

 

double data rate (DDR) two-way interleaved memory (operating at 333MHz) for faster access,

 

 

and incorporates the same renowned IBM Chipkill ECC technology used in more expensive IBM

 

 

servers, for up to 16X better error correction than standard ECC memory.

 

 

Memory must be installed in pairs. It is available in 512MB and 1GB (2GB DIMMs are planned).

 

 

 

 

 

 

 

 

 

Large Disk Storage Capacity

 

 

The e325 offers a choice of disk storage, supporting up to two internal HDDs:

 

 

Hot-swap SCSI

 

 

y Ultra320, 10,000 RPMs — 36.4, 73.4 or 146.8GB (293.6GB maximum)

 

 

y Ultra320, 15,000 RPMs — 36.4 or 73.4GB (146.8GB)

Fixed IDE (ATA-100)

y7,200 RPM — 40, 60, 80 or 120GB (240GB)

The SCSI drives are hot-swappable, while the IDE drives are not. If the customer needs more storage space, terabyte capacities are possible with external IBM ServeRAID SCSI or IBM FAStT Fibre Channel storage solutions. The Ultra320 SCSI hot-swap drives use the Converged Tray for interchangeability with xSeries systems and FAStT expansion units.
