  • Page 11: Introduction

    Introduction The MSA1000 includes a high performance array controller in a 14-drive storage cabinet, capable of 2 Gb/s speeds over Fibre Channel. It may be expanded by adding two more storage cabinets for a total capacity of 42 drives. The MSA1000 is compatible with 1 Gb/s and 2 Gb/s hub and fabric switch interconnects and includes options for embedded switches and hubs.

  • Page 15: Hot-Pluggability

    Introduction Hot-Pluggability Hot-pluggability allows components to be removed and replaced without powering down the MSA1000. The following MSA1000 hardware components are hot-pluggable: Hard Drives—Failed drives in fault-tolerant configurations can be replaced without interrupting system operation. Data on the failed drive is restored automatically to the replacement drive online.
  • Page 16: System Power

    Introduction System Power Power to the MSA1000 does not shut off completely with the power switch. The two positions of the front panel power switch should be considered as on and standby, instead of on and off. The standby position removes power from most of the electronics and the drives, but portions of the power supply and some internal circuitry remain active.

    MSA1000 Hardware Components The standard shipping configuration of the MSA1000 includes one MSA1000 Controller, one MSA Fibre Channel I/O Module, one SCSI I/O Module, and two power supply/blower assemblies. Option kits are available for redundant MSA1000 Controllers and Fibre Channel I/O Modules as well as for embedded switches and hubs. MSA1000 hardware components include: ■...
  • Page 18: Msa1000 Controller

    MSA1000 Hardware Components MSA1000 Controller The MSA1000 Controller is a drive array controller specifically designed for installation in the MSA1000. The MSA1000 comes equipped with one Controller installed. An additional controller for redundancy can be purchased separately. To ensure uninterrupted service, two copies of the controller firmware are stored in Read Only Memory (ROM) on the controller.

  • Page 20: Array Accelerator Features

    MSA1000 Hardware Components The read-ahead cache detects sequential accesses to the array, reads ahead data, and stores the data in the cache until the next read access arrives. If the data is of a sequential nature, the data can be loaded immediately into memory, avoiding the latency of a disk access.
  • Page 21: Array Configuration Overview

    MSA1000 Hardware Components This also applies if the Array Accelerator is removed from the MSA1000 Controller. When power is restored to the MSA1000 storage system, an initialization process writes the preserved data to the disk drives. This is particularly important for data that has been cached by a posted-write operation, but has not yet been written to the hard drives.
  • Page 22: Array Fault Tolerance Levels

    MSA1000 Hardware Components Array Fault Tolerance Levels Fault tolerance refers to several possible methods used to protect your MSA1000 storage system from data loss in the event of a hardware failure somewhere in the storage system. Each method has its advantages; choosing one requires careful planning for your particular requirements.

  • Page 25: Power Supply/Blower Assemblies

    MSA1000 Hardware Components Power Supply/Blower Assemblies The MSA1000 includes redundant power supply/blower assemblies. The power supplies share the electrical load equally. If either supply fails or is removed, the other power supply assumes the full load without interruption. Hot-pluggability allows you to replace the failed supply without shutting down the MSA1000 storage system.
  • Page 26: Fibre Channel I/O Module

    MSA1000 Hardware Components Fibre Channel I/O Module The Fibre Channel I/O Module is a single-port, 1-Gb/2-Gb Fibre Channel device that includes a 2 Gb/s Small Form Factor Pluggable Transceiver (SFP) port. This module can be removed and replaced with other interconnect options, such as the MSA SAN Switch 2/8 or the MSA Hub 2/3.
  • Page 27: Msa San Switch 2/8

    MSA1000 Hardware Components MSA SAN Switch 2/8 The MSA SAN Switch 2/8 is an optional 2-Gb/s, integrated 8-port fabric switch (1 port internal to the MSA1000), that enables full duplex non-blocking performance on all ports. For information about the MSA SAN Switch 2/8, refer to the HP StorageWorks MSA SAN Switch 2/8 Installation Guide.
  • Page 28: Msa Hub 2/3

    MSA1000 Hardware Components MSA Hub 2/3 The MSA Hub 2/3 is an optional input/output device designed to replace the single port Fibre Channel I/O Module that comes standard with the MSA1000. This option is designed to provide an inexpensive and easy way for a clustered pair of servers to access the storage controller (using the arbitrated loop configuration) without having to buy an external hub or switch.
