ServeRAID Ultra160 SCSI Family

The ServeRAID-4 Ultra160 SCSI products offer advanced RAID technology to help manage your business storage needs. These new offerings complement this line by improving performance over the predecessor ServeRAID-4M and -4L Ultra160 SCSI Controllers. Combining a ServeRAID-4 controller with an xSeries or Netfinity® server results in superior performance, availability, and scalability to meet your business storage requirements.

New ServeRAID Ultra160 SCSI Controllers

The ServeRAID-4Mx and -4Lx Ultra160 SCSI Controllers provide higher levels of performance. They are powered by a 100 MHz Intel Zion GC80303 processor that provides:

  • 66 MHz PCI bus performance for xSeries and Netfinity servers containing a 66 MHz PCI bus
  • Up to 528 MB/s data transfers across the PCI bus

As members of the popular ServeRAID-4 SCSI Controller family, they offer:

  • Leadership performance and reliability
  • Support for up to 14 HDDs per channel — Provides massive RAID-protected data storage

  • Manageability and ease-of-use through ServeRAID Manager software
  • Support for nine RAID levels — More choices to meet unique business needs

ServeRAID-4Mx Ultra160 SCSI Controller: This dual-channel, mid-range controller:

  • Includes 64 MB ECC SDRAM battery-backed ECC cache
  • Contains two channels supporting internal and external connections:
    • Two internal, 68-pin, ANSI connectors — Flexible internal connections
    • Two external industry-standard .8-mm VHDCI connectors — Supports moderate external RAID-protected data storage

ServeRAID-4Lx Ultra160 SCSI Controller: This very affordable, single-channel, entry-level controller includes:

  • 32 MB of ECC cache — Provides balanced performance
  • Support for either an internal or an external connection:
    • One internal, 68-pin, ANSI connector
    • One external industry-standard .8-mm VHDCI connector

Key Features of ServeRAID-4Mx and -4Lx Controllers

  • Support for Ultra160 SCSI data transfer rates — up to 160 MB/s
  • Support for RAID levels 0, 1, 1E, 5, 5E, 00, 10, 1E0, and 50
    • RAID levels 1E, 1E0 and 5E are IBM exclusives

  • Support for adapter failover in Windows NT environments
  • Support for clustering with Microsoft Cluster Services and NetWare High-Availability Services

ServeRAID-4Mx and -4Lx Useability: Excellent usability features are provided by the ServeRAID-4 controllers for setting up, monitoring, and modifying the disk array. Logical Drive Migration (LDM) is included with ServeRAID controllers. It allows various complex RAID setup and maintenance operations to be administered in a simple straightforward manner.

Product Positioning

The ServeRAID-4Mx and -4Lx Ultra160 SCSI Controllers outperform the predecessor products, the ServeRAID-4M and -4L Ultra160 SCSI Controllers. These new controllers are positioned beneath the ServeRAID-4H Ultra160 SCSI Controller that provides greater performance and additional channels for greater storage function.

These new controllers are scheduled to replace the ServeRAID-4M and -4L controllers in the upcoming months.
