Description
Product overview of HP 443999-001 256MB PCI Express
The HP 443999-001 is a RAID (Redundant Array of Independent Disks) controller that can support both SATA (Serial Advanced Technology Attachment) and SAS (Serial Attached SCSI) hard drives. The controller is designed to work with servers that use PCI Express x8 interfaces, and it can support up to 256MB of memory.
A RAID Controller
A RAID controller is a hardware device that manages multiple hard drives to work together as a single logical unit. It provides fault tolerance and improved performance by distributing data across multiple disks. A RAID controller can operate in different modes, such as RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10. Each mode offers a different level of performance and data protection.
PCI Express x8 Interface
The HP 443999-001 RAID controller is designed to work with servers that have a PCI Express x8 interface. PCI Express is a high-speed serial computer expansion bus that connects the motherboard to peripheral devices. The x8 interface provides eight lanes of data transmission and can support a maximum bandwidth of 4 GB/s.
SATA and SAS Support
The HP 443999-001 RAID controller supports both SATA and SAS hard drives. SATA is a popular interface for consumer-grade hard drives, while SAS is a more robust interface designed for enterprise-class storage systems. SAS offers higher data transfer rates, better error detection and correction, and more advanced features, such as hot-swapping and dual porting.
256MB Memory
The HP 443999-001 RAID controller can support up to 256MB of memory. The memory is used for caching data and improving performance. The controller can use different types of memory, such as DDR2 or DDR3, depending on the specific model.
Smart Array Technology
The HP 443999-001 RAID controller uses Smart Array technology to manage the RAID arrays. Smart Array technology provides advanced features, such as online capacity expansion, logical drive extension, and RAID level migration. These features allow administrators to manage their storage systems more efficiently and without disrupting operations.
Online Capacity Expansion
Online Capacity Expansion (OCE) is a feature of Smart Array technology that allows administrators to expand the capacity of a RAID array while the system is still running. OCE is a non-disruptive process that does not require downtime or data migration. This feature is useful for organizations that need to add more storage capacity to their systems without disrupting operations.
Logical Drive Extension
Logical Drive Extension (LDE) is another feature of Smart Array technology that allows administrators to extend the logical drives without having to rebuild the RAID array. This feature is useful for organizations that need to add more storage capacity to their systems without having to copy the data to a new array.
RAID Level Migration
RAID Level Migration (RLM) is a feature of Smart Array technology that allows administrators to migrate the RAID level of a logical drive to a higher level. For example, an administrator can migrate a RAID 1 array to a RAID 5 array without having to copy the data to a new array. RLM is a useful feature for organizations that need to change their data protection level or performance requirements.
In Summary, The HP 443999-001 RAID controller is a high-performance storage device that provides advanced features for managing RAID arrays. It supports both SATA and SAS hard drives and can operate in different RAID modes. The controller is designed to work with servers that have a PCI Express x8 interface and can support up to 256MB of memory. Smart Array technology provides advanced features, such as online capacity expansion, logical drive extension, and RAID level migration, which allow administrators to manage their storage systems more efficiently.
