    Chapter 1 - Getting Started The power feed must be electrically isolated from any AC power source, provide a reliable connection to earth (battery room positive bus is connected to the grounding electrode), and capable of providing up to 600 watts of continuous power per feed pair. Overcurrent Protection Requirements Overcurrent protection devices must be provided as part of each equipment rack.

  • Page 17: Cooling Fan Module

    Chapter 1 - Getting Started If any one fan should fail, cooling redundancy and efficiency are degraded. The cooling fans and enclosure temperature are constantly monitored by the SAF-TE processor for fault conditions. In the event of a fault condition the front panel Fan Status LED will change from a green state to a solid amber state in the case of a fan failure, or to a blinking amber green state in the case of an over-temperature condition.

  • Page 18: Saf-Te Disk I/O Card

    Chapter 1 - Getting Started The SAF-TE Disk I/O card has a firmware-based VT-100 interface which provides an option to manage fan speed. This option provides a whisper mode fan operation for noise sensitive environments. When enabled (default), and based on a set of conditions, the software will manage the cooling fans RPM speed to maintain the enclosure temperature while minimizing noise levels.
  • Page 19 Chapter 1 - Getting Started At power up, the SAF-TE processors read the SCSI switch settings and configures the system for the appropriate addresses. It then executes instructions from firmware performing a self-test diagnostics. The firmware is flash upgradeable using the SAF-TE RS-232 Service port located below the I/O card slots at the rear of the enclosure.

    Chapter 2 - Theory of Controller Operation A Word about Clustering Minimizing Downtime for Maximum Data Availability So-called open systems, such as Windows NT servers, just don’t provide the level of availability that IS managers are familiar with on mainframes. A partial solution to this problem is server clustering.
  • Page 29 Chapter 2 - Theory of Controller Operation from one node to two nodes. Going from one node to a four node cluster generally yields a 2.5x or 3x performance boost. However, the cluster performance is application dependent. For example, READ operations may yield a 1.8x performance increase going from one to two nodes, but in a WRITE intensive application, you may only see a 1.4-1.6x improvement.
