Ultra320 SCSI Controller

The integrated single-channel Ultra320 SCSI controller (LSI 53C1020) allows speeds of up to 320MB per second5 across the SCSI bus and supports two internal Ultra320 or Ultra160 SCSI LVD (low-voltage differential) drives with selectable RAID-1disk 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:

yServeRAID-6M — Ultra320, 2-channel,256MB battery-backed cache, 133MHz PCI-X

yServeRAID-6M — Ultra320, 2-channel, 128MB battery-backed cache, 133MHz PCI-X

yServeRAID-4Lx— Ultra160, 1-channel, 32MB cache, 66MHz PCI

yATA-133 RAID Controller (IDE) — ATA-133, ATA-100, ATA-66, 2-channel, half-length

The ServeRAID-4and ServeRAID-6Mcontrollers 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® (PFA).

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.

64-bit High-Speed PCI-X Adapter Slots

The e325 has one full-lengthand one half-lengthadapter 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.

Other New Features

yFour USB 1.1 ports — The flexibility to add more external devices, with two ports in the front and two in the rear.

yHigh-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.

yUSB-attached floppy drive support — Optional drive can be relocated to share among multiple systems.

yToolless features — No tools are required for rack installation, cover removal, adapter retention, power supply replacement or HDD installation/removal.
