Adapters for ThinkServer
Product Guide (withdrawn product)
The Emulex OCe14000 family of 10 Gb Ethernet Networking and Converged Networking Adapters for ThinkServer builds on the foundation of previous generations of Emulex Ethernet adapters by delivering performance enhancements and new features that reduce complexity and cost and improve performance. With FCoE and iSCSI offloads standard on most adapters in the family, these adapters delivers a set of powerful features and capabilities that are designed for the virtualized enterprise environment, multi-tenant and single- tenant cloud environments, I/O intensive environments, and converged infrastructure environments. Figure 1 shows the 2-Port SFP Converged Network Adapter.

Did you know?
The Emulex OCe14000 family of adapters for ThinkServer are equivalent to the VFA5 family of adapters for System x with some differences. The  Ce14000 adapters support Universal Multi-Channel virtualization, which is equivalent to switch independent mode (vNIC2) in System x. The VFA5 adapters support Virtual Fabric NIC (vNIC1), Unified Fabric Port (UFP), and vNIC2. The OCe14000 and VFA5 adapters share common drivers and can be managed by Emulex OneConnect management software.

Features

The Emulex OCe14000 family of adapters for ThinkServer offers virtualized networking, supports a converged infrastructure, and improves performance with powerful offload engines. The adapter has the following features and benefits.
Reduce complexity

• Virtual NIC emulation
  The Emulex OCe14000 adapters all support Universal Multi-Channel virtualization, which is equivalent to switch independent mode (vNIC2) in System x. With NIC virtualization, each of the 10 GbE physical ports on the adapter can be logically configured to emulate up to four virtual NIC (vNIC) functions with user-definable bandwidth settings. With a four-port adapter, up to 16 vNIC functions are supported. With the 40 GbE adapter, up to 16 vNIC functions are supported on the 40 GbE port. Also, each physical port can simultaneously support a storage protocol (FCoE or iSCSI).

• Common drivers and tools
  You can deploy faster and manage less when you implement Emulex adapters for ThinkServer and System x Ethernet, Converged Network Adapters (CNAs), and Virtual Fabric adapters (VNAs) and Fibre Channel Host Bus Adapters (HBAs). Ethernet, CNAs, VFAs, and HBAs that are developed by Emulex use the same installation and configuration process, which streamlines the effort to get your server running and saves you valuable time. They also use the same Fibre Channel drivers, which reduces time to qualify and manages storage connectivity. With Emulex’s OneCommand Manager, you can manage Emulex adapters through the data center from a single console.

Reduce cost

• AnyFabric form factor adapters are a lower-cost offering and do not use a PCIe slot The AnyFabric adapters are a mezzanine-style adapter design that is supported in servers, such as the RD550 and RD650. AnyFabric adapters do not occupy a regular PCIe slot. Although they occupy minimal space in the server chassis that is similar to an onboard adapter, they allow the flexibility that is not available with a built-in controller. AnyFabric adapters are often cheaper than their PCIe counterparts.
• Multi-protocol support for 10 GbE The Emulex OCe14000 adapters offer a “triple play” of converged data, storage, and low latency RDMA and RDMA over Converged Ethernet (RoCE) networking on a common Ethernet fabric. The Emulex CNAs provide customers with a flexible storage protocol option for running heterogeneous workloads on their increasingly converged infrastructures.
• Power savings
  When compared with previous generation Emulex adapters, the Emulex OCe14000 family you can save up to 50 watts per server, which reduces energy and cooling OPEX through improved storage offloads.

Improve performance

• VXLAN/NVGRE offload technology
  Emulex supports Microsoft’s network virtualization by using generic routing encapsulation (NVGRE) and VMware’s virtual extensible LAN (VXLAN). These technologies create more logical LANs (for traffic isolation) that are needed by cloud architectures. Because these protocols increase the processing burden on the server’s CPU, the OCe14000 adapters have an offload engine that is designed for processing these tags. The resulting benefit is that cloud providers can realize the benefits of VXLAN/NVGRE while not being penalized with a reduction in the server’s performance.

• Full hardware storage offloads
  The Emulex OCe14000 adapters support a hardware offload engine as standard that accelerates storage protocol processing, which enables the server’s processing resources to focus on applications. This benefit improves the server’s performance.

• Advanced RDMA capabilities
  RoCE delivers application and storage acceleration through faster I/O operations with support for Windows Server SMB Direct and Linux NFS protocols. With RoCE, the adapters help accelerate workloads in the following ways:
  ° Capability to deliver a 4x boost in small packet network performance versus previous generation adapters, which is critical for transaction-heavy workloads
  ° Desktop-like experiences for VDI with up to 1.5 million FCoE or iSCSI I/O operations per second (IOPS)
  ° Ability to scale Microsoft SQL Server, Exchange, and SharePoint by using SMB Direct which is optimized with RoCE
  ° More VDI desktops and servers because of up to 18% higher CPU effectiveness (the percentage of server CPU usage for every 1 Mbps I/O throughput)
  °  Superior application performance for VMware hybrid cloud workloads because of up to 129% higher I/O throughput compared to adapters without offload

NIC virtualization

The Emulex OCe14000 adapter family supports NIC virtualization with the Universal Multi-Channel (UMC) feature. With UMC, each physical port is divided into four virtual ports; therefore, for a 2-port adapter, you can have up to eight virtual NICs per adapter. The default bandwidth for each vNIC is 2.5 Gbps. Bandwidth for each vNIC is configured in the adapter and IEEE 802.1Q VLAN tags are used to separate the vNIC functions. The VLAN tags are added to the packet by the applications or drivers at each endpoint. vNIC bandwidth allocation and metering are performed by the adapter. The bandwidth of each vNIC can be between 100 Mbps and 10 Gbps with up to a total of 10 Gb per physical port (a total of 40 Gb per port for the 40 Gb adapter).
The vNICs can also be configured to have 0 bandwidth if you must allocate the available bandwidth to fewer than four vNICs per physical port. A unidirectional virtual channel is established in which the bandwidth management is performed only for the outgoing traffic on the adapter side (server-to-switch). The incoming traffic (switch-to-server) uses all available physical port bandwidth because no metering is performed on the adapter or switch side.
When storage protocols are enabled on the adapter, the following virtual port counts apply:

• 10 Gb adapters: Up to two vNICs (one per physical port) can be iSCSI or FCoE. The remaining six vNICs (three per physical port) can be Ethernet.
• 40 Gb adapter: Up to four vNICs can be iSCSI or FCoE. The remaining 12 vNICs can be Ethernet.
