Chassis Install Instructions (734751-001, March 2014)

Confirming warranty support and finding out about related services
The standard warranty protects against product defects and some causes of downtime. You can
extend your warranty with HP Care Pack Services. This portfolio of predefined packages is flexible,
allowing you to extend coverage to the exact level of support required. You choose the support
level that meets your business requirement, from basic to mission-critical.
Recommended service levels and appropriate related services for your particular disk enclosure
model are listed on the QuickSpecs. For more information, see the Storage Services website:

Gathering and recording information
A brief worksheet is included on the getting started instructions that is shipped with the disk
enclosure. As you gather and identify the hardware and software components for your environment,
use the worksheet to record information about your components and your configuration. Some
information is easily obtained before installing the disk enclosure, while some of the information
is created during the configuration process.
A basic worksheet is included on the poster, but HP recommends creating and keeping more
detailed records.
Information recorded on the worksheet is used during the initial system setup and configuration,
and is helpful for future configuration changes and troubleshooting purposes.
NOTE: If a supplier is installing or configuring your disk enclosure, provide them with the poster,
and verify that they complete the worksheet and record other important configuration and set up
information.
Planning the storage configuration
Proper planning of the system storage and its subsequent performance is critical to a successful
deployment of the disk enclosure. Improper planning or implementation can result in wasted storage
space, degraded performance, or inability to expand the system to meet growing storage needs.
Storage planning considerations include:
• System and performance expectations
• Striping methods
• RAID levels
• Disk drive sizes and types
• Spare drives
• Array sizing (capacity)
NOTE: For the minimum supported configuration, and other configuration information, see the
QuickSpecs for the disk enclosure.
System and performance expectations
To help determine the best way to configure your storage, rank the following three storage
characteristics in order of importance:
• Fault tolerance (high availability)
• I/O performance
• Storage efficiency
With priorities established, you can determine which striping method and RAID level to use; some
configuration methods offer greater fault tolerance, while other configuration methods offer better
I/O performance or storage efficiency.
