NOTE: The MSA operates in a non-redundant mode during this procedure. a. Access a supported management utility for the MSA. b. In the utility, disable the controller to be removed. For details, see the utility online help or MSA user documentation. c. Wait for array controller disabled to display on the controller LCD panel. d. Remove the disabled controller for servicing or replacement. CAUTION: If an operational controller is removed without first being disabled, the active controller might halt. To clear this fault condition, you must power-cycle the MSA. For more information, see the HP StorageWorks 1000 Modular Smart Array maintenance and service guide, available on the Technical documentation page of the MSA1000 website: http://www.hp.com/go/msa1000 . Plan your storage configuration Proper planning of the system storage and its subsequent performance is critical to a successful deployment of your MSA. Improper planning or implementation can result in wasted storage space, degraded performance, or inability to expand the system to meet growing storage needs. Considerations include: • System and performance expectations • Striping methods • RAID levels • Hard drive sizes and types • Spare drives • Array sizing (capacity) System and performance expectations To help you determine the best way to configure your storage, you must first rank the following three storage characteristics in order of importance: • Fault tolerance (high availability) • I/O performance • Storage efficiency With your priorities established, you can determine which striping method and RAID level to use. As highlighted in the following sections on Striping methods and RAID levels, some configuration methods offer greater fault tolerance, while other configuration methods offer better I/O performance or storage efficiency.
