Storage controller overview

The information in this document might differ from your product if it contains custom configuration options or features. The following information is subject to change over time. For the most up-to-date information, contact H3C Support.

The software screenshots used in this document are for illustration only and might differ from your products or versions.

The model name of a hardware option in this document might differ slightly from its model name label.

A model name label might add a prefix or suffix to the hardware-coded model name for purposes such as identifying the matching server brand, applicable region, or capacity. For example, the RAID-LSI-9560-LP-16i-8GB or LSI-9560 storage controller model represents the storage controller model name label UN-RAID-LSI-9560-LP-16i-8GB-M.

Storage controllers provide powerful I/O transmission and bandwidth processing capabilities and support various RAID expansions to improve system performance. With support for multi-disk fragment storage of data and data read/write concurrency over multiple disks, storage controllers effectively reduce disk access delay and can meet RAID requirements in various scenarios.
