Other New Features
y Four USB 1.1 ports — The flexibility to add more external devices, with two ports in the front
and two in the rear.
y High-resolution video — Up to 1600x1200 resolution, with a color depth of 24 bits at 85Hz
refresh rate, using the ATI Rage XL SVGA video controller.
y USB-attached floppy drive support — Optional drive can be relocated to share among
multiple systems.
y Toolless features — No tools are required for rack installation, cover removal, adapter
retention, power supply replacement or HDD installation/removal.
64-bit High-Speed PCI-X Adapter Slots
The e325 has one full-length and one half-length adapter slot, capable of supporting 100MHz
64-bit and 32-bit PCI-X adapters and/or older 64-bit and 32-bit 66MHz and 33MHz PCI adapters.
Because the Ultra320 SCSI, dual Gigabit Ethernet and systems management controllers are
integrated onto the system board, the two available high-speed adapter slots offer customers a
wide degree of latitude in expansion options.
Dual-Channel Gigabit Ethernet Controller
The e325 includes a two-channel integrated Broadcom BCM5704 Gigabit Ethernet controller for
up to 10X higher maximum throughput than the dual 10/100 Ethernet controllers used in some
systems. Having integrated controllers saves PCI slots. Optional PCI adapters offering failover
and load balancing between them are available for better throughput and system availability.
Ultra320 SCSI Controller
The integrated single-channel Ultra320 SCSI controller (LSI 53C1020) allows speeds of up to
320MB per second

across the SCSI bus and supports two internal Ultra320 or Ultra160 SCSI
LVD (low-voltage differential) drives with selectable RAID-1 disk mirroring.
Optional IBM ServeRAID controllers increase the RAID support to nine different levels. For
low-cost RAID support of internal IDE drives, use the ATA-133 RAID Controller. Supported RAID
controllers include:
y ServeRAID-6M — Ultra320, 2-channel, 256MB battery-backed cache, 133MHz PCI-X
y ServeRAID-6M — Ultra320, 2-channel, 128MB battery-backed cache, 133MHz PCI-X
y ServeRAID-4Lx — Ultra160, 1-channel, 32MB cache, 66MHz PCI
y ATA-133 RAID Controller (IDE) — ATA-133, ATA-100, ATA-66, 2-channel, half-length
The ServeRAID-4 and ServeRAID-6M controllers support external SCSI expansion via the IBM
EXP300 Storage Expansion Unit. Each EXP300 adds up to 2.055TB of external Ultra160 SCSI
storage capacity.
The RAID subsystem is closely linked with IBM Director to allow proactive monitoring of the disk
subsystem. This feature is used to generate alerts in the event of an impending disk failure or an
actual disk failure via Predictive Failure Analysis

What’s Hot?
Dual SMP Processors with HyperTransport Technology
The e325 supports up to two high-performance AMD Opteron processors, allowing customers to
upgrade to a second processor as business needs require.
HyperTransport technology is a high-speed, low-latency, point-to-point link, designed to increase
the communication speed between circuits. It eliminates a key bottleneck currently caused by the
Outstanding 32/64-bit price/performance in a rack-dense 1U, 2-way server for HPC
applications

Data transfer rates depend on many factors and are often less than the maximum possible.
