QLogic NPAR Technology Widely Available for Critical I/O Virtualization Requirements in the Data Center
ALISO VIEJO, Calif., Oct 27, 2011 (GlobeNewswire via COMTEX) -- Continuing to execute on its Adaptive Convergence(TM) strategy, QLogic Corp. (Nasdaq:QLGC) today announced that its NIC partitioning (NPAR) switch-agnostic, I/O virtualization solution is now available to channel partners on QLogic(R) 3200 Series intelligent Ethernet adapters and 8200 Series converged network adapters. Standard with QLogic 3GCNA adapters, QLogic VMflex(TM) NPAR technology is the most widely available solution for critical I/O virtualization requirements in the data center and serves as a precursor to industry-standard I/O virtualization technologies such as Single Root I/O Virtualization (SR-IOV) across a wide variety of operating systems.
QLogic VMflex delivers the numerous benefits of I/O virtualization for any of today's industry-standard or proprietary OEM virtualized environments. As enterprises transition to virtualized and cloud-based environments, QLogic adapters with VMflex reduce virtualized operating system (OS) software overhead on the physical controller to avoid bottlenecks and provide VM portability that can be used to follow cloud-based and virtual resources wherever they are provisioned.
"ESG research indicates that just over 30 percent of server virtualization users cited that they will soon have 25 or more VMs per physical host, dramatically increasing I/O traffic," said Bob Laliberte, senior analyst for ESG. "QLogic developed VMflex and NPAR I/O virtualization technology specifically to handle these increased loads and enable enterprises to enhance performance and network utilization, while simultaneously reducing complexity."
The demand and complexity of I/O traffic has increased significantly in the virtualization era. If not properly managed, I/O can negatively impact application performance and limit the number of virtual machines (VMs) deployed. I/O bottlenecks and memory performance issues can be reduced by giving VMs direct access to hardware I/O devices, eliminating the overhead of embedded software switches and improving system performance while reducing system power consumption and providing greater cost-savings. While the SR-IOV specification will enable multiple guest operating systems to simultaneously access an I/O device without having to rely on the software (hypervisor), SR-IOV requires support that is not yet available from most OS vendors.
To address the gap between present and future, QLogic built the powerful NPAR feature into VMflex. NPAR allows users to divide a single physical Ethernet port into four partitions or virtual ports with the capability to run TCP/IP, Fibre Channel over Ethernet (FCoE) or iSCSI on any of the virtual ports in a converged environment. As the industry gears up to fully support SR-IOV, QLogic NPAR, available now, provides the same benefits to customers today, as well as a seamless path to future SR-IOV deployments.
"As enterprises transition to virtualized and cloud-based environments, virtual I/O is a primary consideration in any company's IT strategy," said Amit Vashi, vice president of marketing, Host Solutions Group, QLogic. "With the ability to create multiple partitions--each supporting TCP/IP, FCoE or iSCSI--and take advantage of flexible bandwidth provisioning on our 10GbE converged network adapters, VMflex reduces adapter, cabling, switch port, and management costs and gives customers more options in choosing Ethernet switches. VMflex enables the application of quality-of-service (QoS) to virtual ports, improving I/O performance while maintaining a low total cost-of-ownership."
By providing NPAR technology to channel partners on the QLogic 3200 Series of intelligent Ethernet adapters and 8200 Series converged network adapters, QLogic is now the industry's first to ship switch-agnostic NIC partitioning technology to end-users on its company-branded and OEM-branded adapters.
