6 Implementing Cisco InfiniBand on IBM BladeCenter
The benefits of the blade approach will be obvious to anyone tasked with running down
hundreds of cables strung through racks just to add and remove servers. With switches and
power units shared, precious space is freed and blade servers enable higher density with far
greater ease.
There are two InfiniBand daughter cards available for IBM BladeCenter servers:
Cisco InfiniBand 1X HCA Expansion Card, part number 32R1896
Cisco InfiniBand 4X HCA Expansion Card, part number 32R1760
For information about the 4X daughter card, see 2.2, “Cisco 4X InfiniBand HCA Expansion
Card” on page 18.
Table 1-1 shows which blade servers support the InfiniBand daughter cards.
Table 1-1 Blade servers and InfiniBand support information
We describe the HS21, LS21, and JS21 in the following sections.
1.2.1 BladeCenter HS21 XM server
The BladeCenter HS21 XM (extended memory) servers are positioned as high-density
servers. With one or two dual-core or quad-core Intel processors plus up to 32 GB of DDR2
memory with 8 DIMM sockets, they represent a new approach to the deployment of
application servers where performance, capacity, high-availability design, systems
management, and easy setup features are combined in an extremely dense package.
Reducing an entire server into as little as .5U of rack space does not mean trading away
features and capabilities for smaller size.
Integrated dual Gigabit Ethernet controllers are standard, providing high-speed data transfers
and offering TCP Offload Engine (TOE) support, load-balancing and failover capabilities.
Through optional expansion cards, each blade can also connect to additional Ethernet,
Myrinet, Fibre Channel, iSCSI, InfiniBand, and other high-speed communication switches
housed in the chassis. Optional 2-port Expansion Cards add additional fabrics to the HS21
XM server as needed. This blade is designed with power management capability to provide
the maximum uptime possible for your systems. In extended thermal conditions or power
