• QLogic further expands broadest portfolio of QDR InfiniBand solutions with industry’s first QDR IB Pass-Through Module

• New QLogic 12005-PT16 QDR Pass-Through Module available for Dell PowerEdge blade servers• Designed to fit seamlessly into the Dell PowerEdge M1000e chassis• Provides dedicated 40Gb/sec QDR IB interface for Dell blade servers • Extends connectivity from the server’s IB mezz card to any external,

industry-standard IB switch

• QLogic raises the stakes in the HPC sector

The News

March 2010

QLOGIC CONFIDENTIAL7

• A Mellanox internal blade server switch occupies two slots and is limited to a specific location in each half of the Dell Blade server

• This limits customer configuration options; a major client complaint• Q’s single slot solution has no limitations and 45% power savings• Q’s 12005-PT16 is a cost-effective alternative for cluster computing

• Eliminates latency associated with internal switch hops• Connects blade servers directly to external QDR core switches

• By taking up only a single I/O fabric module space in Dell servers, the 12005-PT16 frees other PowerEdge I/O modules for expanded configuration options

Why This is Important
