QLogic FlexSuite adapters offer PCIe 3.0 support

QLogic announced recently that its FlexSuite line of adapters now support PCIe 3.0 for servers running Intel Xeon E5-2600/1600 v2 processors, which the company said will

help eliminate I/O bottlenecks while dealing with large data workloads.

QLogic's FlexSuite 2600 Series Gen 5 Fibre Channel adapters and 8300 Series Converged Network Adapters are intended for data-intensive situations, such as cloud deployments, virtualization and heterogeneous environments, according to the company.

The adapters also feature "port-level isolation architecture," which the company said improves reliability by using two independent channels, and either port can operate securely even if its counterpart encounters problems.

QLogic said the 8300 series also offers support for multiprotocol traffic -- including TCP, Fibre Channel over Ethernet and iSCSI -- for servers based on the new Intel chips. The 8300 series adapters also support SR-IOV, which allows for multiple guest operating systems to share I/O access in a device without using a software hypervisor.

The addition of PCI Express (PCIe) 3.0 support for the Xeon E5-2600/1600 v2 processors will help users of environments relying on those processors to deploy clouds for platform and data protection applications, as well as make the handling of big data loads more efficient, according to a statement from Intel.

Greg Schulz, founder of the Stillwater, Minn.-based analyst firm StorageIO, said PCIe 3.0 is an important enabling technology for the cloud, for virtual and physical computing, as well as technologies that can be taken for granted, like storage I/O and networking. He said small changes on a large scale can have big improvements due to the reduction in overhead for the data-encoding scheme.

"In the past, improvements have been tied mainly to increased clock speed or adding more bits and bytes, [and] with this generation, there are some clock speed enhancements," Schulz said. "However, there is also a significant reduction in the overhead, meaning more actual work or data gets moved."
