Description
Product overview of 462918-001 HP Smart Array P411 PCI-E
The 462918-001 HP Smart Array P411 is a PCI-E X8 SAS Raid LP (Low-Profile) controller card that is designed to provide advanced RAID capabilities and data protection for servers and storage systems. In this article, we will provide a detailed explanation of the features and benefits of the HP Smart Array P411 controller card.
PCI-E X8 Interface
The HP Smart Array P411 controller card features a PCI-E X8 interface, which provides high-speed connectivity to the server’s mainboard. The PCI-E X8 interface offers a maximum data transfer rate of 2GB/s per lane, which results in a total bandwidth of 16GB/s for the controller card. This high-speed interface ensures that the controller card can efficiently handle large amounts of data traffic and reduce data latency.
SAS RAID Capabilities
The HP Smart Array P411 controller card offers advanced SAS RAID capabilities, which include RAID levels 0, 1, 10, 5, 6, 50, and 60. These RAID levels provide different levels of data protection and performance optimization for different types of applications and workloads. RAID 0 offers high performance and no data redundancy, while RAID 1 provides complete data redundancy at the cost of reduced performance. RAID 10 offers a combination of high performance and data redundancy, while RAID 5 and 6 provide data protection with distributed parity. RAID 50 and 60 offer a combination of data striping and data mirroring for high-performance and high-reliability applications.
Advanced Data Protection
The HP Smart Array P411 controller card offers advanced data protection features, which include online capacity expansion (OCE), online RAID level migration (RLM), and drive roaming. OCE allows users to add more drives to the RAID array without disrupting the system’s operation, while RLM enables users to change the RAID level of an existing array without data loss or system downtime. Drive roaming allows users to move drives between different slots on the controller card without disrupting the RAID array’s operation.
Battery-Backed Write Cache
The HP Smart Array P411 controller card features a battery-backed write cache, which provides enhanced data protection in case of power failure or system crash. The write cache holds data in volatile memory before writing it to the disk, which can improve system performance. However, in case of a power outage or system crash, the write cache can lose its data, which can result in data loss or data corruption. The battery-backed write cache ensures that the data in the write cache is saved to the disk in case of a power outage or system crash, which reduces the risk of data loss or data corruption.
Low-Profile Design
The HP Smart Array P411 controller card features a low-profile design, which makes it suitable for use in servers and storage systems with limited space. The low-profile design allows the controller card to fit into a half-height PCI-E slot, which is commonly found in rack-mount servers and storage systems. The low-profile design also helps to improve system airflow and reduce cooling requirements.
Compatibility
The HP Smart Array P411 controller card is compatible with a wide range of HP ProLiant servers and storage systems, including HP ProLiant ML/DL/SL servers, HP StorageWorks Modular Smart Array (MSA), and HP StorageWorks Enterprise Virtual Array (EVA). The controller card also supports a wide range of SAS and SATA hard drives and solid-state drives (SSDs).
In Summary,The HP Smart Array P411 controller card is an advanced SAS RAID controller card that offers high-speed connectivity, advanced data protection, and a low-profile design. The controller card is compatible with a wide range of HP ProLiant servers and storage systems and supports a wide range of SAS and SATA hard drives and SSDs. The HP Smart Array
