Review HP Dual Port Pci e Hca Full Height

The HP 661685-001 554QSFP Dual Port PCIe HCA (Half-Height, Add-in Card) is a high-performance data storage solution designed for servers and data centers. This HBA (Host Bus Adapter) is equipped with two QSFP (Quad Small Form-factor Pluggable Plus) ports, enabling it to support high-speed data transfer rates of up to 40 Gbps per port and delivering a total bandwidth of 80 Gbps.

This HP HBA is based on the HP 55400 series controller, which is known for its reliability and robustness. It is a half-height, dual-port add-in card, making it an excellent choice for servers where space is a concern. The card is designed to fit into standard PCIe slots, ensuring easy installation and compatibility with a wide range of servers.

The HP 661685-001 HBA supports both Fibre Channel and iSCSI protocols, allowing it to connect to a variety of storage systems, including Fibre Channel arrays, iSCSI targets, and NAS (Network-Attached Storage) devices. This versatility makes it an ideal solution for data centers that require a high-bandwidth connectivity option for their storage infrastructure.

This HBA also comes with built-in RAID support, allowing it to protect data by providing redundancy in the event of a drive failure. The card supports various RAID levels, including RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10.

The HP 661685-001 HBA is designed with power efficiency in mind. It features HP's Power Savings System (PSS) technology, which helps to reduce power consumption by putting idle ports into a low-power state. This not only helps to reduce energy costs but also contributes to a greener data center.

This HP HBA comes with the HP Smart Array P816i RAID controller firmware pre-installed, making it easy to manage and configure. The card also supports HP's Intelligent Provisioning feature, which simplifies the process of provisioning new LUNs (Logical Unit Numbers) to servers.

In summary, the HP 661685-001 554QSFP Dual Port PCIe HCA is a high-performance, versatile, and efficient data storage solution designed for servers and data centers. With its support for high-speed data transfer rates, compatibility with various storage protocols, built-in RAID support, power-saving features, and easy-to-use management software, this HBA is an excellent choice for organizations that require a reliable and robust storage connectivity solution.

The HP 661685-001 554QSFP 649281-B21 Dual Port PCIe HCA is a high-performance, dual-port Fibre Channel Host Bus Adapter designed for data center environments. This HBA allows servers to connect to Fibre Channel storage systems or switches for transferring data at high speeds. Let's discuss the pros and cons of purchasing this particular model.

1. High-Performance: With dual 6Gbps Fibre Channel ports, this HBA offers high-speed data transfer, making it suitable for handling large workloads in data-intensive applications.

2. Dual Port: Having two ports increases the availability and reliability of the data transfer, as servers can switch to the other port if one fails or is under heavy load.

3. Hot-Pluggable: The hot-plug design allows for easy installation, replacement, or maintenance without requiring system downtime.

4. Broad Compatibility: This HBA is compatible with various server models and operating systems, ensuring versatility in different environments.

5. Robust: HP is a well-established brand with a reputation for producing high-quality, reliable hardware, ensuring that the HBA is robust and reliable.

1. High Cost: Compared to other PCIe HBAs, this model is more expensive due to its high-performance capabilities and dual-port design.

2. Fibre Channel Connectivity: While Fibre Channel is a proven technology for enterprise storage, it may not be as common or accessible as other connection types like iSCSI or Ethernet.

3. Requires Fibre Channel Infrastructure: To utilize this HBA, you need a Fibre Channel infrastructure, which includes cabling, switches, and storage systems, adding to the overall cost and complexity.

The HP 661685-001 554QSFP 649281-B21 Dual Port PCIe HCA is an excellent choice for organizations that require high-performance, reliable, and dual-port Fibre Channel connectivity for their data center applications. Its compatibility with various server models and operating systems, hot-plug design, and robustness from a reputable brand are additional benefits. However, its high cost and the requirement for a Fibre Channel infrastructure may deter some potential buyers. Ultimately, if your organization's needs align with the HBA's features, it can be a worthwhile investment.

If you're in the market for a high-performance, dual-port Fibre Channel Host Bus Adapter, the HP 661685-001 554QSFP 649281-B21 is a solid choice due to its robust design, compatibility, and reliability. However, carefully consider your organization's requirements, budget, and existing infrastructure before making a purchase. If Fibre Channel is not a necessity, alternative options like iSCSI or Ethernet HBAs might be more cost-effective for your needs.
