8 Installing and Maintaining HCA Cards and Mezzanines A feature of InfiniBand fabrics is that individual components can contain an InfiniBand host channel adapter (HCA), or as in the case of an HP BladeSystem server blade, a mezzanine HCA. Every device containing an HCA is a visible and manageable part of the InfiniBand fabric. The HCA can be an integrated circuit that is embedded on the circuit board of a device, (such as a storage array controller) or it can be in the form of a PCI card that you install in a server. In HP Cluster platform, the HCA can be a single-port, or a dual-port InfiniBand PCI card. This chapter thoroughly describes Voltaire HCA cards and briefly describes several other models used in HP Cluster Platform as follows: • Voltaire HCA 400 PCI-X and HCA 400 PCI-Express. (See Section 8.1). • Installing the HCA, (See Section 8.2). This chapter also provides brief descriptions of the various HCAs used in HP Cluster Platform: • Topspin/Mellanox SDR PCI-X. (See Section 8.3). • Topspin/Mellanox SDR PCI-Express. (See Section 8.4). • Mellanox SDR PCI-X. (See Section 8.5). • Mellanox SDR PCI-Express. (See Figure 8-6). • Mellanox Memory-Free SDR PCI-Express. (See Section 8.7). • Mellanox Memory-Free DDR PCI-Express. (See Section 8.8). • Mellanox DDR PCI-Express. (See Section 8.9). • HP HPC 4x DDR IB Mezzanine HCA (See Section 8.9.2). Note: Specific combinations of HCA card and card firmware are required to support operating environments such as HP XC.

Information about the HCA-400 and HCA-400Ex is provided in this section. In the text, the card is referred to as the HCA and any differences between the two models are clearly specified.

8 Installing and Maintaining HCA Cards and Mezzanines
A feature of InfiniBand fabrics is that individual components can contain an InfiniBand host
channel adapter (HCA), or as in the case of an HP BladeSystem server blade, a mezzanine HCA.
Every device containing an HCA is a visible and manageable part of the InfiniBand fabric. The
HCA can be an integrated circuit that is embedded on the circuit board of a device, (such as a
storage array controller) or it can be in the form of a PCI card that you install in a server. In HP
Cluster platform, the HCA can be a single-port, or a dual-port InfiniBand PCI card. This chapter
thoroughly describes Voltaire HCA cards and briefly describes several other models used in HP
Cluster Platform as follows:
•
Voltaire HCA 400 PCI–X and HCA 400 PCI–Express. (See
Section 8.1
).
•
Installing the HCA, (See
Section 8.2
).
This chapter also provides brief descriptions of the various HCAs used in HP Cluster Platform:
•
Topspin/Mellanox SDR PCI–X. (See
Section 8.3
).
•
Topspin/Mellanox SDR PCI–Express. (See
Section 8.4
).
•
Mellanox SDR PCI–X. (See
Section 8.5
).
•
Mellanox SDR PCI–Express. (See
Figure 8-6
).
•
Mellanox Memory-Free SDR PCI-Express. (See
Section 8.7
).
•
Mellanox Memory-Free DDR PCI-Express. (See
Section 8.8
).
•
Mellanox DDR PCI-Express. (See
Section 8.9
).
•
HP HPC 4x DDR IB Mezzanine HCA (See
Section 8.9.2
).
Note:
Specific combinations of HCA card and card firmware are required to support operating
environments such as HP XC.
