Product Description
HP supports both software-based and hardware-based RAID. For example, HP now implements software RAID in embedded SATA controllers in some of the ProLiant servers and RBSU is used to enable it. Software-based RAID It is possible to have a RAID configuration without an array controller. This is known as software RAID. With software-based RAID, the array management functions are implemented by software executing in a host environment such as the operating system. Software RAID requires additional transfers across the I/O bus. Although software RAID is not as versatile as hardware RAID, it offers a cost-effective, entry-level, fault-tolerant solution. The advantages of software-based RAID are: - The ability to span multiple host controllers (duplexing) - Lower cost Hardware-based RAID With hardware-based RAID, the array management functions are implemented by the hardware and firmware within a RAID controller. The RAID controller orchestrates read and write activities in the same way a controller for a single disk drive does, treating the array as if it were a single physical or logical drive. Hardware-based RAID is transparent to the host software and is self-contained within the storage solution. It does not interfere with the primary function of the host, which translates into higher overall performance and a potential for advanced RAID capabilities. With a hardware RAID solution, there is no extra activity on the I/O bus, memory bus, or frontside bus after the data reaches the array controller. All RAID-related activities are local to the array SCSI bus. When a single sector is written to the disk, 64 transfers are executed on a 64-bit PCI bus. The advantages of hardware-based RAID are: - Faster, more reliable performance than software RAID - Support for RAID 1+0 or RAID ADG - Support for online spare drives - Decreased processor load - User-friendly configuration utilities - No operating system interface required when starting a rebuild Advantages of HP hardware-based RAID HP implements RAID at the hardware level with value-added features in its Smart Array controllers. The advantages of HP hardware-based RAID are: - Safe write caching through a battery-backed array accelerator on some models - Superior manageability such as multiple volumes with different RAID levels - High flexibility such as separating I/O in to different disk volumes - Automatic recovery and online spares - Automatic data distribution and I/O balancing across multiple disk drives - Superior performance and I/O optimization
