QLE7240 Host Channel Adapter.
The QLE7240 InfiniBand (IB) Double
Data Rate (DDR) HCA delivers industry-leading performance for a cluster
interconnect and allows organizations to gain maximum advantage and
return from their investment in clustered systems. As a result, organizations
relying on clustered systems for critical computing tasks will experience a
significant increase in productivity.
High Performance Computing (HPC).
The QLE7240, with its low latency,
high messaging rate, and increased bandwidth, provides the key building
block for HPC clustering systems.
Data Center and Enterprise.
The supporting software includes standards-
based high performance sockets, a Linux TCP/IP stack, an OpenFabrics
(OFED) stack, and QLogic’s value added Upper Layer Protocols (ULPs) over
OFED. For data center applications, the QLE7240 supports storage and
networking.
With three different stacks available, the high performance sockets and
the Linux TCP/IP stack can be used simultaneously with the OFED stack.
QLogic also provides management features such as IFS tools and subnet
management.
Interoperability.
InfiniBand ecosystem partner certifications, combined with
agency and regulatory testing, ensures all products meet industry compliance
with hardware and software specifications. All HCAs are tested extensively
with third-party hardware, along with multiple software applications, to
ensure best-in-class InfiniBand interoperability and compatibility.
Investment Protection.
For over 15 years, QLogic has been a technological
leader with products that address the current needs of customers, yet
provide strong investment protection to support emerging technologies and
standards. QLogic stands alone in the industry with its product portfolio
depth and experience in successfully delivering technological solutions that
address the needs of today and tomorrow.
