Configuring the InfiniteStorage 6120
This section provides information on configuring your InfiniteStorage 6120.
NOTE :
The configuration examples provided here represent only a general guideline.
These examples should not be used directly to configure your particular InfiniteStorage
6120.
The CLUI (command line user interface) commands used in these examples are fully
documented in Sections

2.3.1
Planning Your Setup and Configuration
Before proceeding to configure the storage settings for the InfiniteStorage 6120, it is necessary to
understand the basic organization of the system.
The InfiniteStorage 6120 uses storage pools and virtual disks to configure drive storage for use by
host systems. A storage pool (sometimes referred to as a RAID group) is a collection of 5 to 10 disk
drives, ideally of the same capacity and type. In RAID5, the capacity of one drive is reserved for
parity, allowing data recovery in the event of a single drive loss in the storage pool. In RAID6, the
capacity of two drives is reserved for parity, allowing data recovery if either one or two drives are
down in a storage pool.
A single RAID5 storage pool can be configured using 5 or 9 drives. A single RAID6 storage pool can
be configured using 6 or 10 drives. The InfiniteStorage 6120 supports up to 24 storage pools in a
single system. A storage pool can be configured with drives of different capacity, in which case the
InfiniteStorage 6120 will use the lowest capacity for all drives, but this is not recommended.
A virtual disk is the storage unit presented to any attached host. Virtual disks allocate space in 8 GiB
increments. For example, 16 GiB of storage space will be allocated when creating a virtual disk of
10 GiB. You can create up to 64 virtual disks per storage pool.
NOTE :
In this document, the terms
GB
and
GiB
are used interchangeably and denote
1,073,741 bytes (2
30
bytes).
The drives in the system are categorized into one of the following pools:
• Unassigned pool - By default, all the drives or replacement drives are initially allocated to this
pool. When a drive has failed or been released (from a spare pool, for example) it is also moved
to this pool.
• Storage pool (sometimes referred to as a RAID group) - A collection of 5 to 10 disk drives,
ideally of the same capacity and type.
• Spare pool - This type of pool contains drive(s) that can be used as spare drives in one or more
storage pools.
