Ship: Call for next available delivery Features The Intel X520 and X540 adapters have the following features: Load balancing on multiple processors, which increases performance on multiprocessor systems by efficiently balancing network loads across processor cores when used with Receive Side Scaling from Microsoft or Scalable I/O on Linux. Header Splits and Replication in Receive helps the driver focus on the relevant part of the packet without needing to parse it. Multiple queues allow packet handling without the waiting/buffer overflow, which provides efficient packet prioritization. Storage offloads: The ThinkServer adapters listed in Table 2 support the following storage protocols: FCoE (Data Center Bridging DCB, Converged Enhanced Ethernet CEE) iSCSI The X520 OCP adapter for the sd350 supports iSCSI but does not support FCoE.
