with existing 10GbE installations while allowing an upgrade to 25GbE full 25GbE bandwidth per port. Public and private cloud virtualized server infrastructure. This technology enables cloud providers and large-scale farms can now achieve 2.5 times the VM density for the best price and VM data center operators to reduce operating expense while continuing ratio. to scale their network of server and storage nodes to meet increasing demands of the future. QLogic 25GbE technology is cost-efficient WIRE-SPEED NETWORK VIRTUALIZATION and power-efficient because it uses a single lane, compared to other Enterprise-class data centers can be scaled using overlay networks to alternatives such as quad-lane 40GbE. The QL41262HMKR CNA is carry VM traffic over a logical tunnel using NVGRE, VXLAN, and GENEVE. compatible with 25Gbps lanes used in 100GbE switches, paving the way Although overlay networks can resolve virtual LAN (VLAN) limitations, to a seamless upgrade path to to connect to 100GbE switches that have native stateless offloading engines are bypassed, which places a higher 4×25GbE capability. load on the system’s CPU. STREAMLINING NETWORKING WITH SWITCH INDEPENDENT QLogic FastLinQ QL41262HMKR 10/25GbE CNAs efficiently handle this PARTITIONING load with advanced NVGRE, VXLAN, and GENEVE stateless offload engines Switch Independent Partitioning helps simplify the data center and that access the overlay protocol headers. This access enables traditional the network and storage infrastructure in several ways. For example, stateless offloads of encapsulated traffic with native-level performance when connecting servers, administrators may need to use many cables, in the network. Additionally, FastLinQ QL41262HMKR 10/25GbE CNAs sometimes adding switches to reduce cable proliferation. Switch support VMware NSX® and Open vSwitch (OVS). Independent Partitioning provides an alternative: consolidating connections onto significantly reduced numbers of devices. Like switches, Switch HYPER-SCALE ORCHESTRATION WITH OPENSTACK Independent Partitioning reduces the number of cables without adding QLogic FastLinQ QL41262HMKR 10/25GbE CNAs support the OpenStack workloads on the network. However, Switch Independent Partitioning open source infrastructure for constructing and supervising public, private, requires fewer devices compared to using switches and cables, thereby and hybrid cloud computing platforms. They provide for both networking reducing network sprawl, maximizing network scalability, and simplifying and storage services (block, file, and object) for iSER. These platforms administration. allow providers to rapidly and horizontally scale VMs over their entire, diverse, and widely spread network architecture to meet the real-time ACCELERATE ANY NETWORK WITH UNIVERSAL RDMA OFFLOAD needs of their customers.
