Step 1: Review and confirm your plans
Before installing your MSA1500 cs, HP recommends thoroughly researching,
studying, and establishing an installation and configuration plan for your
environment. Proper planning ensures a successful installation of your
MSA1500 cs.
■Complete the planning worksheet on the configuration overview poster
■Go to the Internet for the most recent MSA1500 cs and SAN information
■Plan your storage configuration
■Review MSA1500 cs installation best practices
Complete the planning worksheet on the configuration overview poster
The printed MSA1500 cs Configuration Overview poster, included in the shipping
carton, is a companion to this Installation Guide, and should be completed before
installing your MSA1500 cs.
Use the poster to:
■Gather all of the components necessary for installing your MSA1500 cs
■Verify that the components you plan to use are supported for use with the
MSA1500 cs and your operating system environment
■Record important information about the components that you plan to use
■Learn about this installation process
Record system information in the worksheets in Appendix C: “MSA1500 cs
Worksheets” on page 85 or on the poster.
Information in these worksheets is required for multi-pathing, future
configuration changes, and troubleshooting purposes.
Note: If a supplier is installing the MSA1500 cs for you, be sure that they complete
these worksheets.

Plan your storage configuration
Proper planning of system storage and its subsequent performance is critical to a
successful deployment of your MSA1500 cs. 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
■LUN 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.

20 Modular Smart Array 1500 cs Installation Guide
Striping methods
A storage array combines the capacity of several physical hard drives into one
virtual unit called an array or logical unit (LUN.) These LUNs are then presented
to the operating system as a single disk device. The physical layout of a LUN can
be one of two configurations:
■Vertical striping
■Horizontal striping
In a vertical configuration, a LUN uses hard drives from separate storage
enclosures and different SCSI buses. In a horizontal configuration, the LUN uses
multiple drives contained within the same storage enclosure.
Vertical and horizontal LUNs each have advantages and disadvantages:
— Vertical striping offers ultimate fault tolerance and performance, but at the
price of storage efficiency
— Horizontal striping allows for the creation of large LUNs and efficient use
of storage capacity, but at the price of I/O performance and less fault
tolerance.
RAID levels
In conjuction with the striping method, the assigned RAID level also determines
the fault-tolerance, I/O performance, and storage efficiency of the LUN.
See Table 3 on page 21 for a comparison list of the different RAID levels.
When selecting a RAID level for a LUN, consider the type of data that will be
stored on the array.
For example:
■For transitional data, you may want to use RAID 0, which provides no fault
tolerance, but provides rapid storage and access of large amounts of data.
■For critical data, use a fault-tolerant RAID level, such as RAID 1, RAID 1+0,
RAID 5, or RAID ADG, choosing the RAID level that offers the desired
combination of fault-tolerance, I/O performance, and storage efficiency.
Depending on the assigned RAID level, one or more drives within a LUN can fail
without bringing the drive sub-system down.
